Gresswell Forest with George Paras

WEBVTT
00:00:00.000 --> 00:00:07.200
I'd like to acknowledge the Wandru Warong people as the traditional owners of the land where this recording was made.
00:00:10.960 --> 00:00:18.160
Over the past few months, I've been walking through reserves around Melbourne, NAM, and recording conversations along the way.
00:00:18.399 --> 00:00:28.079
I've met with traditional owners and First Nations peoples, conservationists, ecologists, and others who've chosen a place that matters to them.
00:00:28.480 --> 00:00:35.280
We walk and talk about nature, what lives there, what's changed, and what needs protecting.
00:00:35.520 --> 00:00:43.439
You'll hear our footsteps, the wind in the trees, the birds overhead, and the city not too far away.
00:00:44.079 --> 00:00:47.759
This is Finding Melbourne's Nature.
00:00:52.399 --> 00:00:58.560
Today, we're walking through Greswell Forest in Melbourne's Northeast with the legendary George Paris.
00:00:59.119 --> 00:01:10.159
George spent more than 36 years as a ranger at Latrobe's Lightlike Temporary Wildlife Sanctuary, helping to restore and care for the Greswell Forest as well as the surrounding bushland.
00:01:10.719 --> 00:01:15.120
These days he works in ecological restoration and environmental education.
00:01:15.359 --> 00:01:20.400
But as we got started, George told me about his career in conservation and how it was an accident.
00:01:20.799 --> 00:01:28.319
While studying at Latrobe, Electra noticed his interest in native fish and suggested he meet the head ranger Rod Foster.
00:01:28.640 --> 00:01:30.480
That set everything in motion.
00:01:30.799 --> 00:01:40.319
George got involved in environmental groups, found mentors and a community, and stayed with it, eventually building a career working on the ground in restoration.
00:01:40.560 --> 00:01:44.640
As we walk, George shares his knowledge of decades in the field.
00:01:44.879 --> 00:01:52.159
What works, what doesn't, what it takes to bring the landscape back, and the relationships that hold it all together.
00:02:08.400 --> 00:02:08.960
Thanks, Ben.
00:02:09.039 --> 00:02:09.280
Yeah.
00:02:09.439 --> 00:02:17.039
So Greswell Forest is a place I met when I was a uni student at La Trobe in the early 80s.
00:02:17.360 --> 00:02:23.039
At the time it was being managed by La Trobe University, Wildlife Reserves Department.
00:02:23.439 --> 00:02:32.080
La Trobe Uni had a wildlife reserve established on its own land going back to the 60s when La Trobe was established.
00:02:32.159 --> 00:02:37.759
It was meant to have a place, a biological reserve, like a big outdoor lab.
00:02:38.639 --> 00:02:42.879
And there were people working on that since 1967, 68.
00:02:43.599 --> 00:02:50.240
But particularly in the 70s, the focus there started on indigenous restoration.
00:02:50.639 --> 00:02:58.800
And there were a whole lot of people that were students at La Trobe in the 70s and academics that drove the direction.
00:02:58.879 --> 00:03:10.240
And to the best of my knowledge, it's the first ecological restoration project in Melbourne, if not Victoria, where the emphasis was on recreating indigenous things.
00:03:10.800 --> 00:03:26.960
Now, at some time in the 70s, Gresle Forest as an important remnant of grassy woodland was being seen by the naturalists, the botanists, the students, the postgrads at La Trobe as a valuable resource.
00:03:27.919 --> 00:03:38.479
And the then head ranger at La Trobe University Wildlife Reserves, the late Rod Foster, he and others were collecting seed in Gresle Forest.
00:03:38.560 --> 00:03:47.360
So some of his contemporaries like Jeff Carr, Randall Robinson, Cam Betzel, others, they knew Gresel Forest was quite important.
00:03:48.159 --> 00:04:07.759
And I don't know the exact details, but somehow the interest in conserving Gresel Forest led to a campaign by the Vice-Chancellor, Professor John Scott, to approach the mental health authority, because this land was part of that greater hospital system around Mont Park.
00:04:08.319 --> 00:04:15.039
And I'll get on to why areas of bush like this survived, and it was no longer needed for its original purpose.
00:04:15.199 --> 00:04:23.279
Its original purpose was, as bush land, clean air, around the Greswell tuberculosis sanatorium.
00:04:23.439 --> 00:04:24.000
Oh really?
00:04:24.399 --> 00:04:32.079
So back in the year old days, uh people coming back from wars or whatever when there were tuberculosis were isolated.
00:04:32.319 --> 00:04:40.079
They were given good nutrition and fresh air until they recovered, until modern medicine caught up with the treatment.
00:04:40.480 --> 00:04:50.160
And of course, they had buffers around them with no cattle grazing, no agricultural activity, and a place for people to recuperate.
00:04:50.480 --> 00:04:58.720
And that's why there's a hell of a lot of bush around Greswell Hill, Gresl Forest, and all that that had survived right through the 70s.
00:04:58.959 --> 00:05:04.319
Greswell Sanatorium was no longer tuberculosis sanatorium in the 70s.
00:05:04.560 --> 00:05:10.800
It became an alcohol rehabilitation centre, Greswell Hospital for drug and alcohol rehabilitation.
00:05:11.199 --> 00:05:30.800
And so back in those days, surplus crown land that was no longer needed for health purposes could easily move to a university for education and conservation purposes without needing to be sold like surplus crown land and public assets are these days.
00:05:31.120 --> 00:05:32.079
Fascinating.
00:05:32.240 --> 00:05:33.439
So that's why it's here now.
00:05:33.600 --> 00:05:34.560
Yeah, so that's why it's here.
00:05:34.800 --> 00:05:37.279
And what did it look like when you first saw the place?
00:05:37.680 --> 00:05:45.040
Well, I started volunteering down at the wildlife reserve at La Trobe Buny in the early 80s.
00:05:45.839 --> 00:05:53.759
I was introduced to it, not because I was doing botany or zoology or ecology, I was actually an agricultural science student.
00:05:54.000 --> 00:06:00.319
And one of my animal sciences lecturers, he was on the management committee of the wildlife reserves.
00:06:00.480 --> 00:06:04.319
And he was of Scottish background and a mad keen fly fisherman.
00:06:04.959 --> 00:06:09.279
And he realised that I knew a lot about fishing and a lot about native fish.
00:06:09.519 --> 00:06:11.279
It was a growing interest of mine.
00:06:12.079 --> 00:06:20.639
And he said, George, you should go over and introduce yourself to the ranger at the Wildlife Reserve, the late Rod Foster.
00:06:21.439 --> 00:06:27.759
He knows a lot about plants, but he doesn't seem to know about fish or anything like that.
00:06:28.240 --> 00:06:34.560
They got these wetlands there, and he said, see if we get some decent fish in there so I could go fishing at lunchtime.
00:06:35.600 --> 00:06:39.199
So I became a volunteer in the Friends of the Wildlife Reserves.
00:06:39.839 --> 00:06:45.279
And there was also a student group that developed a few years later called the Ecological Society.
00:06:45.360 --> 00:06:47.439
It was basically a student naturalist club.
00:06:47.839 --> 00:06:51.199
We hung out at the reserve and did all sorts of things.
00:06:51.600 --> 00:06:56.959
So to set the scene where it's sort of walking up a hill, how do you describe this forest in front of us?
00:06:57.199 --> 00:07:05.759
Well these days, this southwestern part of south eastern part of Greswell Forest with its westly aspect is a lot denser than it was back then.
00:07:06.000 --> 00:07:08.480
There's been a lot of regeneration.
00:07:08.560 --> 00:07:16.959
The eucalypts, which had survived that hospital era, official clearing had ceased in the early 1900s.
00:07:17.360 --> 00:07:19.519
There was still firewood collecting.
00:07:19.680 --> 00:07:21.920
I know that from other locals.
00:07:22.240 --> 00:07:34.480
I've moved into the McLeod area and there was even a wood merchant, firewood merchant, that used to come in here in the hospital lands, and he'd target things that were easy work.
00:07:34.959 --> 00:07:38.639
And he'd target also, particularly yellow box, I found out later.
00:07:38.800 --> 00:07:45.680
So some of the lesser representation of yellow box is probably because it was selectly harvested in the early days.
00:07:45.839 --> 00:07:46.319
Right.
00:07:46.560 --> 00:07:48.000
So it was more open.
00:07:48.240 --> 00:08:00.079
Now, of course, a lot of the seedlings of River Redgums and some of the wattles that were here in the early 80s have now grown to full height or maturity.
00:08:00.319 --> 00:08:01.360
It's a lot woodier.
00:08:01.439 --> 00:08:03.439
There's some shrubs that have come in over the years.
00:08:03.600 --> 00:08:07.600
Yeah, we're walking through now what looks like stunning bush.
00:08:07.680 --> 00:08:17.519
That when you look at an aerial photo, it looks like there's all these housing developments around it, yet in this bush right now, you don't have a feeling at all that you're surrounded by suburbia.
00:08:17.600 --> 00:08:22.160
It feels rich and big and the ground story is in fantastic condition.
00:08:22.480 --> 00:08:24.160
Yeah, very few weeds.
00:08:24.480 --> 00:08:32.080
We had had at one stage in the 90s a huge grant from Melbourne Water.
00:08:32.399 --> 00:08:41.919
And we're grateful because Tamera Creek Management Committee pushed the boundaries as to where Melbourne water funding could go.
00:08:42.799 --> 00:09:07.039
They were the first agency that argued that this pool of money that had been developed, which was originally the Melbourne Metropolitan Border Works, Parks and Waterways Division pie of money, that other agencies that were managing substantial metropolitan open space and waterways should be able to bid for.
00:09:24.159 --> 00:09:27.600
And we did some major work in the Creek Valley that we'll walk past later.
00:09:27.840 --> 00:09:28.960
I look forward to it.
00:09:29.279 --> 00:09:35.440
What was the hydrology like, do you think, before this area had been interfered with in any sense?
00:09:35.840 --> 00:09:44.480
So about 20% of this 50-hectare reserve was just thickets and deltas of weeds.
00:09:44.879 --> 00:10:05.279
The bits that weren't affected by stormwater were where you had the intact understory, you had a dormant seed bank, so new indigenous plants would occasionally surprise us as the you know the mass of grassy of the grassy layer you know was suppressed.
00:10:06.080 --> 00:10:08.159
The grass layer composition changed.
00:10:08.240 --> 00:10:11.279
In areas that were more open and sunny, they were dominated by thermata.
00:10:11.440 --> 00:10:14.639
They later became dominated by uh weeping grass.
00:10:14.799 --> 00:10:15.120
Yeah.
00:10:15.279 --> 00:10:18.159
Now some botanists say, well, that's a problem.
00:10:18.720 --> 00:10:20.000
Well, is it or isn't it?
00:10:20.080 --> 00:10:27.200
Was it the previous scenario just the fireprone ecosystem that kept it open?
00:10:27.440 --> 00:10:32.240
What happened before all human intervention and land management?
00:10:32.559 --> 00:10:34.799
Uh areas might have been woodier, okay?
00:10:35.519 --> 00:10:42.080
Gullies were and riparian strips were bushier, were lusher, etc.
00:10:42.320 --> 00:10:50.879
So and speaking of riparian, we're standing, um it's a marvellous cue for what we're standing over right now.
00:10:51.120 --> 00:10:51.759
What have we got here?
00:10:51.840 --> 00:10:54.399
Is this all stormwater or is there a natural creek line?
00:10:54.639 --> 00:10:55.840
This is a natural creek line.
00:10:55.919 --> 00:11:05.440
This is one of the three uh tributary creek lines that go together to form the west branch of the Salt Creek that flows down to MacLeod.
00:11:05.600 --> 00:11:11.919
But on this branch here, we're sitting around a small artificial farm dam, you could call it.
00:11:12.240 --> 00:11:15.840
So this was constructed before my time.
00:11:16.399 --> 00:11:26.879
Back in the late 80s, I started putting indigenous wetland plants into it and we created a bit of an island and planted that out.
00:11:27.120 --> 00:11:31.759
So it's got swamp paper bark as well as naturally regenerated wood at lands, etc.
00:11:32.000 --> 00:11:49.279
So ended up we ended up focusing on this area and making sure that a lot of those weeds of disturbance around the periphery were dealt with through restoration because just up there, and Park's Tory has put a rootproof fence around that, is the famous wildflower patch.
00:11:49.440 --> 00:11:50.720
The famous wildflower patch.
00:11:50.960 --> 00:11:53.759
Yeah, that was like the pinnacle of you know grassy woodland thing.
00:11:53.840 --> 00:11:56.480
That's the one with you know the most species and all of that.
00:11:56.559 --> 00:12:00.080
That was the one that after the 82, 83 fires, people took photos of it.
00:12:00.240 --> 00:12:05.200
There's slides somewhere on file of you know just wildflower meadows.
00:12:05.440 --> 00:12:07.039
Is it still as good?
00:12:08.159 --> 00:12:08.399
No.
00:12:08.720 --> 00:12:11.759
No, not not not not as good, but there's a longer history there.
00:12:11.919 --> 00:12:15.120
But interestingly, there's a whole story here.
00:12:15.440 --> 00:12:20.480
We would become like West wetland plant, wetland restoration experts.
00:12:20.559 --> 00:12:22.559
We were helping others on small projects.
00:12:22.639 --> 00:12:29.519
We were running courses of how to improve your wetland, you know, for hobby farmers, for people in other land management agencies, etc.
00:12:30.720 --> 00:12:38.960
And we had a field day here where we even had uh uh fish biologist John McGuckin with some of his survey equipment here.
00:12:39.440 --> 00:12:44.399
And we did a survey here because we thought we could bring it here because someone had dumped some goldfish here.
00:12:44.559 --> 00:12:50.799
And we thought, oh, we'll demonstrate, you know, the techniques and maybe get a few of those goldfish out, which we did.
00:12:51.600 --> 00:12:59.120
And in the middle of the workshop, he picked up two individual climbing a Galaxius.
00:12:59.600 --> 00:13:00.159
How's that work?
00:13:00.480 --> 00:13:02.000
The Galaxis Breverpenis.
00:13:02.159 --> 00:13:02.480
Yeah.
00:13:03.360 --> 00:13:14.960
Now this is a fish that back then managed to get past that 1967 lump of concrete that people call dye.
00:13:15.200 --> 00:13:18.879
It's I'm not gonna call it falls, it's a weir.
00:13:19.120 --> 00:13:19.440
Yeah.
00:13:19.840 --> 00:13:20.480
Right?
00:13:20.879 --> 00:13:23.919
So those fish breed in the estuary.
00:13:24.240 --> 00:13:29.600
And they and diadromus, they head upstream and colonize the roots.
00:13:29.919 --> 00:13:39.919
And out of all the galaxia family and galaxia species, they're the ones that are more capable of getting up past wet surfaces.
00:13:40.159 --> 00:13:53.600
You know, if you've ever been on a fish survey and got Galaxy Brevapinus in the bucket, you go to pour the water out, some of them are climbing up the sides of the bucket, you know, the last to sort of, you know, exit the bucket.
00:13:53.840 --> 00:14:01.679
So you think about those two fish that were found up here, they have come up the Yarra, all the way to Heidelberg.
00:14:01.919 --> 00:14:17.519
At Heidelberg, near Warringle Park, they've done a left turn up Salt Creek, past the old Anglican historical church there, where there's a you know sort of bluestone channel from the 1800s, etc.
00:14:18.000 --> 00:14:23.759
They've crossed under Rosanna Road into that concreted drain section.
00:14:24.559 --> 00:14:28.080
You think Melbourne Water pouted a lot of in the post-war years?
00:14:28.480 --> 00:14:33.440
There was one agency that poured more than Melbourne Water, it was the Dandelong Valley Authority.
00:14:34.480 --> 00:14:38.240
Concrete drains were dirty in the 60s and 70s.
00:14:38.399 --> 00:14:54.399
And this thing came up to about Edgar Street, then entered a drain, a barrel drain, and proceeded upstream for almost a kilometre under Lower Plenty Road, Rosanna near the service station, and saw sunlight again at Rosanna Parklands.
00:14:54.639 --> 00:15:46.240
And these fish would have gone up through Rosanna Parklands, nice bit of you know, open waterway, all the way to behind the McLeod Tennis Courts near McLeod Railway Station, and would have entered another barrel drain that went all the way up to that retarding basin at Harry Potter Reserve that we passed on the way here, where they would they would have seen sky at one caged pit, and their drive, they would have kept going right up that drain, right up through the Dunvegan estate, and we came in at the south end gate of Greswell Forest, near the Dunvegan Park, uh near the corners of Vincent Street, and they would have then found Greswell Forest and thought, wow, and got into this habitat that you'd newly created with beautiful plants.
00:15:48.080 --> 00:15:49.360
Get here too.
00:15:50.159 --> 00:15:56.639
So we've got to see this land management, bush land that we manage is part of the continuum.
00:15:56.879 --> 00:16:04.159
It's like now there's people putting up maps of the Yarra showing all its tentacles.
00:16:05.360 --> 00:16:07.279
So we we're all part of that.
00:16:07.919 --> 00:16:09.120
Life in a catchment.
00:16:09.279 --> 00:16:16.639
And so those two ambassadors of their species, there's a whole story of what goes on there.
00:16:16.720 --> 00:16:25.200
And you start thinking about there was one fishway attempt on at Dyes Falls using the old historical raceway.
00:16:25.360 --> 00:16:32.000
That worked to some extent, but it also served to uh threaten the heritage, you know, the bluestone mill raceway.
00:16:32.159 --> 00:16:34.960
So they built a new one next few years later.
00:16:35.039 --> 00:16:40.159
And so you go to Dyes Falls on the north side, and there's this whole caged fishway.
00:16:40.399 --> 00:16:43.120
The reality is very few fish get past it.
00:16:43.279 --> 00:16:48.879
A lot do, but it's high velocity, even though it's got sort of spots and whatever.
00:16:49.200 --> 00:17:00.799
And for small-bodied native fish, of which millions depend on being you know born in the estuary or the salem waters, they like the shallow riffles.
00:17:01.840 --> 00:17:03.360
So what happens there?
00:17:03.679 --> 00:17:16.160
A lot of fish, I'd say I I don't know the science, would just live out their life in that big sort of salem kayak circuit, not find their way into the fishway.
00:17:16.640 --> 00:17:23.200
If anything, they're probably going to the far side of Galaxia Point on the south side where it's the shallow beach side of the Yarra.
00:17:23.920 --> 00:17:26.960
And you know, some of those smaller fish would prefer to think here.
00:17:27.200 --> 00:17:32.559
But things like Climb Galaxius have made it up the kunung, uh the Mullum.
00:17:33.039 --> 00:17:39.759
So a lot of the area that's been impacted by North East Link works was that wonderful restoration bit of the kunang.
00:17:39.920 --> 00:17:50.400
When the Eastern Freeway was linked, they uh did some wonderful work with wetlands, artificial creeks, re-vegetation along there, and that's been redug up again.
00:17:50.960 --> 00:18:01.599
Wow, so the potentially the fish here have a relationship with the Yarrow River and the estuary parts right out of towards the bay.
00:18:01.839 --> 00:18:02.319
Yep.
00:18:02.559 --> 00:18:07.279
And at some point they probably move downstream again if they get the urge to breed.
00:18:08.160 --> 00:18:25.920
This is what blows me away is like thinking about all these relationships that we we don't understand and how much of an impact it has when we have development and things that could break that um tenuous length that we have and that that that journey that you've described of where the fish have travelled, that's incredible to think.
00:18:26.079 --> 00:18:30.160
There've been that whole journey to get to a place that's safe and healthy here.
00:18:30.480 --> 00:18:33.440
And live out there, you know, sort of adult life pre-breeding.
00:18:33.759 --> 00:18:37.839
And a huge thanks to you for giving them a safe and comfortable home.
00:18:38.079 --> 00:18:40.160
There's a lot of things we don't see, these aren't seen things.
00:18:40.319 --> 00:18:40.640
Yeah.
00:18:40.960 --> 00:18:49.599
Like we we look at the uh surface vegetation, we don't look at the subterranean seed bank.
00:18:49.839 --> 00:19:11.680
So restoration, long-term, we're trying to exhaust the weed seeds, but we've probably got uh propagules, whether they're seed or corms or bobs or spores, orchids, lilies, whatever, dinnellas, just by simply resting the land that come up from that dormant seed.
00:19:11.920 --> 00:19:23.519
When they demolish some of those Mont Park uh buildings, some that have been there for 80 years, one of the peas that came up in the area, previously unrecorded in the area.
00:19:23.839 --> 00:19:25.680
Lying dormant in the soil just ready to come.
00:19:26.000 --> 00:19:29.680
Goodya uh Medico Giana, yeah.
00:19:30.000 --> 00:19:34.960
And Michael Sincota, who was working with us at the time, he sort of found that.
00:19:35.200 --> 00:19:39.039
So we knew Goodyear, a lot of folia occurred in some places near here, etc.
00:19:39.279 --> 00:19:40.240
was growing on this.
00:19:40.640 --> 00:19:43.839
So these are the things uh people don't see.
00:19:44.079 --> 00:19:45.759
What's beneath the ground?
00:19:46.000 --> 00:20:04.799
When you talk about the seed bank still being intact even after 80 years, maybe more, um, does it give you hope when we think about Melbourne conservation that um we could turn some things around and yes, you've got to see the restoration potential in every sod of open space we have.
00:20:05.200 --> 00:20:30.400
You know, we we saw that era, the growth in private consultants and developers ticking boxes, they're reporting on sites and they're being uh scored lowly because no one is there to do this enduring longitudinal work of just leaving bloody rest in the land and dealing with a small number of weeds to show the full potential of these sites.
00:20:31.039 --> 00:20:36.079
So sites are being written off, they're being scored, there's now a more modern scoring thing.
00:20:36.559 --> 00:20:49.200
So what you're saying is that the condition we see it in now might not represent what the potential condition is based on underlying seed sources or um restorative efforts.
00:20:49.519 --> 00:20:58.000
Um and and I've been uh lucky, you know, people look at you like a freak, what you've worked for the same you know job for that many decades.
00:20:58.160 --> 00:21:00.079
Like, you know, what sort sort of freak are you?
00:21:00.319 --> 00:21:04.880
Can't survive in the real competitive world of you know career advancement.
00:21:05.279 --> 00:21:30.559
But I've seen places that were totally wrested, that were farmed on the campus wildlife reserve, in the wildlife sanctuary, that the land was rested long enough that dormant seed bank things came up in areas that had been grazed as part of the Mont Park Psychiatric Hospital, the Great Hospital in the post-war one years, was a dairy farm, was a market garden.
00:21:30.640 --> 00:21:37.519
There were bits that were more ploughed and more fertilized and bits that weren't, people bits that were just cleared and burnt and grazed.
00:21:37.759 --> 00:21:45.839
And we saw how many dinalinas come back in the fourth decade of my career there.
00:21:46.000 --> 00:21:46.640
Yeah.
00:21:47.519 --> 00:21:54.960
There were places on the edge of La Trobe where two species of pterostylus have come up.
00:21:55.039 --> 00:21:56.240
There's some that have come up here.
00:21:56.400 --> 00:21:58.319
Terastylus has never accorded around here.
00:21:58.559 --> 00:21:59.680
To see Terastylus, yeah.
00:22:00.240 --> 00:22:03.839
Go to the east side of Melbourne, the northeast of Melbourne, St.
00:22:04.079 --> 00:22:09.759
Helena, and beyond, and all the terrace is and you see all those orchid photos that naturals take.
00:22:10.000 --> 00:22:29.279
So even in and so I've had long discussions with uh one of the guys uh that became arranged in Park Victoria uh uh and a park planner, Gary French, and he became a keen orchid conservationist orchid enthusiast and conservationist, and now in retirement is actively involved in orchid conservation.
00:22:29.519 --> 00:22:53.680
And there were places up in Pliny Gorge where you'd see an echidna dicking, had done some scarif micro disturbance, probably got into an ant nest, sugar ant nest or something like that, and all of a sudden you'd find certain orchids coming up there, and they weren't in the immediate surrounding area, so you can't say they just uh came up or were there all along.
00:22:54.000 --> 00:23:40.079
And we think that even the finest spores probably survive in these granaries, you know, they're then in ant chambers, the apothecaries of the seed bank, just like peas and wattlesed do, below the surface, where it takes a very intense fire, intense disturbance, in the case of uh uh Goodya, Bedico Giana, or whatever, to come back, but in the same way, even finer spores potentially could be existing in that humidity crib of the right humidity, the right temperature buffering, whatever, and with fungi and germinate after an echidna event.
00:23:40.400 --> 00:23:41.759
Is that bit of disturbance?
00:23:42.079 --> 00:23:43.440
Yes, some things to get it going.
00:23:43.759 --> 00:23:50.240
But it's not just disturbance, it's an echidna, it's an ant nest.
00:23:50.480 --> 00:23:54.480
Anyway, we'll head into the uh wildflower patch.
00:23:54.799 --> 00:24:09.920
Um with so much of your career being around restorative actions and understanding things, I guess we don't have many people like you who've spent, did you say, four decades in this space and watched things and experimented with things?
00:24:11.039 --> 00:24:16.720
Um how do you find the way that things are being managed these days?
00:24:16.799 --> 00:24:21.839
And do you think do you see people coming through who can pick up that mantle of where you left off?
00:24:22.480 --> 00:24:23.680
I don't see a lot of it.
00:24:23.839 --> 00:24:24.000
Yeah.
00:24:24.240 --> 00:24:25.200
Look at look at this area.
00:24:25.359 --> 00:24:29.279
We're we're standing the most biodiverse part of Gresel Forest.
00:24:29.440 --> 00:24:33.519
Someone's been in here with chainsaw chopping down old wattles.
00:24:34.160 --> 00:24:35.200
What were they thinking?
00:24:35.279 --> 00:24:35.759
Yeah, I don't know.
00:24:35.920 --> 00:24:37.759
That old dead wattles are a fire hazard?
00:24:38.079 --> 00:24:38.559
Yeah, I don't know.
00:24:38.799 --> 00:24:41.440
In the middle of nowhere, nowhere near the boundaries.
00:24:41.759 --> 00:24:43.519
They've created this disturbance.
00:24:43.759 --> 00:24:53.839
Do you realise that this area here, Gresel Forest and Gresle Hill, the high bits of ground that aren't affected by drainage are also very important for so many butterflies.
00:24:55.119 --> 00:25:08.319
My eyes were open to you know the plant, insect, ant butterfly associations or grizzle forests early on, by a mate of mine who was also involved in those student organisations who went on to become Australia's butterfly expert, Dr.
00:25:08.400 --> 00:25:09.359
Michael Braby.
00:25:09.839 --> 00:25:10.880
So we're good mates.
00:25:10.960 --> 00:25:18.799
We used to volunteer together under Rod Foster's Tutilage, and I learned about the Imperial Blue Butterflies Association between the ant young wattles.
00:25:19.039 --> 00:25:25.440
He introduced me to this butterfly that occurs in very old senescent wattles.
00:25:26.160 --> 00:25:42.160
And it's uh the azure blue, or it's called something else now, and it's tendered by an ant that lives in the hollows of old senescent wattles, the hollows that have been created by beetle larvae.
00:25:42.240 --> 00:25:47.759
You know, you get those very old death-warmed-up black wattles, for example, or golden wattles.
00:25:47.920 --> 00:25:48.160
Yep.
00:25:48.559 --> 00:25:57.119
Those last few years old wattles are the essential food plant for that butterfly.
00:25:57.200 --> 00:26:08.880
And sent by a species of ant that lives in those old senescent wattles in the hollows created previously by a whole succession of beetles that live in wattles.
00:26:08.960 --> 00:26:11.359
And of course, why does everything live in wattles?
00:26:11.920 --> 00:26:14.960
Because they're nitrogen fixers, they're loaded with amino acids.
00:26:15.119 --> 00:26:16.799
What are the wattles trying to do?
00:26:16.960 --> 00:26:19.279
They're trying to fight off all these herbivores.
00:26:19.519 --> 00:26:35.680
While they're young, they're producing all the nasty herbivore-deturing chemicals they can, the tannins, the alpha toxins, the you know, whatever that legumes do to stop themselves being eaten.
00:26:35.759 --> 00:26:38.400
And as they senesse, they're losing this war.
00:26:38.559 --> 00:26:54.079
They become this living city with millions of invertebrates and fungal succession and galls, and there's a whole, there's tones of books being written by the scientists, entomologists like Tim Yu, who was my boss, he's written tomes about you know uh insect wattle associations.
00:26:54.480 --> 00:27:11.759
And when there's been studies done in the 70s on the invertebrate life on different trees, in random, in proper experimental plots that were trade that planted all these wattles, pinate, non-pinate, those with fire loads, local to Melbourne, non-local to Melbourne.
00:27:12.160 --> 00:27:15.279
And you know who won for the most biodiversity on individual trees?
00:27:15.440 --> 00:27:15.759
Who?
00:27:15.920 --> 00:27:16.799
The indigenous ones.
00:27:16.960 --> 00:27:17.119
Yeah.
00:27:17.279 --> 00:27:31.599
And out of all the indigenous ones, the pinnates, that ugly acacia mercei and acacia dilbata, was scoring up to 600 and 700 taxa of invertebrates on individual trees.
00:27:31.920 --> 00:27:32.880
On individual trees.
00:27:34.240 --> 00:27:34.880
Right?
00:27:35.920 --> 00:27:41.920
The exotics, wattles from New South Wales or West Australia, were below 200.
00:27:42.400 --> 00:27:50.480
So to understand biodiversity and life, we need to understand the role that these species play and and get a better feel for that.
00:27:50.799 --> 00:27:54.480
What do you think the best way to disseminate that information is out to people?
00:27:54.880 --> 00:27:57.839
How do we teach people about these intricacies?
00:27:58.400 --> 00:28:00.960
Well, you join the bloody field, Matt.
00:28:04.720 --> 00:28:05.920
Go out with mentors.
00:28:06.079 --> 00:28:06.400
Yeah, yeah.
00:28:06.640 --> 00:28:08.559
I was lucky, you know, you mentioned some of them, you know.
00:28:08.720 --> 00:28:12.960
People like uh Cam Beardsall had immense patience for me.
00:28:13.039 --> 00:28:17.359
Yeah as a young, you know, volunteer or you know, early industry star.
00:28:17.839 --> 00:28:20.400
People like Randall Robinson, Darcy Duggan.
00:28:20.960 --> 00:28:28.799
They had great encouragement, great approaches to, you know, make you think about what was going on out there.
00:28:31.200 --> 00:28:36.640
We've got a bit of a chorus for people maybe able to hear of the birds around us at this place.
00:28:37.119 --> 00:28:40.720
Is the bird diversity at Greswell Forest quite significant?
00:28:41.119 --> 00:28:41.680
It is.
00:28:42.160 --> 00:28:45.200
It's less uh than it used to be when it started here.
00:28:45.279 --> 00:28:54.640
Like we used to get a lot more insectivores, uh crested shrike tits, but Greswell Forest and La Troy Beuny wildlife centres still turn up some jeb.
00:28:54.880 --> 00:28:59.440
So if you follow the social media, you'll still see we get a whole lot of the robins turn up here.
00:28:59.680 --> 00:29:07.680
We've had uh you know scarlet honey eaters, we've had uh the robins in particular have stayed the the distance.
00:29:08.160 --> 00:29:13.359
We don't uh we still get uh swift parrots in here, occasionally stopping over in this McLeodla Tribunium.
00:29:13.519 --> 00:29:16.480
We're still it still is a good place for bushland birds.
00:29:16.880 --> 00:29:20.079
And you can see uh heaps of dinulla lina.
00:29:20.960 --> 00:29:26.720
When I started here, it was referred to as uh dinola lonifolia.
00:29:26.799 --> 00:29:29.039
Jeff Carr used to call it the nutfield form.
00:29:29.839 --> 00:29:34.319
And we knew it wasn't uh dinulla lonifolia, and it wasn't Dianulla Revoluta.
00:29:34.640 --> 00:29:45.119
And he eventually went on and you know he published the things, and we now know it it's uh endemic to central southern Victoria, its epicenter of you know, it's almost northern Melbourne.
00:29:45.359 --> 00:29:51.839
So for people who might not realise that's a nationally endangered species that's pretty prolific in here for the year.
00:29:52.000 --> 00:29:55.039
Yeah, but we used to manage it at the time, knowing it was different.
00:29:55.200 --> 00:29:55.920
Ah, okay.
00:29:56.160 --> 00:29:59.759
Uh even though we didn't have a botanical name for it.
00:29:59.839 --> 00:30:06.720
And we knew it was different to other lonifolias, which are also found in here, along with Dianella Revoluta.
00:30:08.720 --> 00:30:25.039
So if someone's a land manager and they're thinking about the patch of bush that they're managing, or it whether it's their garden or whether it's a big bush land reserve, what advice would you have for them in terms of thinking about how to plot it out and how to make sure that they went about it the right way?
00:30:25.279 --> 00:30:33.279
Look, I think it's uh synonymous, uh, or similar to moving into a new house, similar advice.
00:30:33.519 --> 00:30:40.400
I wouldn't make any radical changes until you've lived at least a year and seen it in all seasons.
00:30:42.240 --> 00:30:47.119
And then you start on your triage, you think, what can I fix?
00:30:47.839 --> 00:30:50.799
And what you can fix is the alien flora.
00:30:52.400 --> 00:30:56.000
And there's a triage, just a witch alien flora.
00:30:56.480 --> 00:31:05.119
Even the old advice of the Bradley sisters still holds true today in terms of a strategic approach.
00:31:06.319 --> 00:31:08.720
Start with your best years, your outliers.
00:31:08.880 --> 00:31:09.839
So patience.
00:31:10.160 --> 00:31:10.640
Patience.
00:31:11.039 --> 00:31:32.640
Fix what you can fix, what is obvious, in a uh in a way that's sympathetic, minimal impact, got to get people out of vehicles, out of excavators, all this stuff that you know the state agents isn't doing by redeploying these forestry contractors that overcapitalising these machines, that's what it takes.
00:31:32.799 --> 00:31:46.880
It takes bush land restorationists, regenerators, our TAFES, our punching out how many neat or resource management students, whatever the diplomas call these days, conservation land management or whatever it's called, it's changed names.
00:31:47.440 --> 00:31:50.799
There's great people that need work.
00:31:51.039 --> 00:32:03.519
Absolutely, and I think that's why volunteering at a local reserve or a friends group can be really good because you can you can have all sorts of things change around you, but uh you can still play a role in that reserve's future.
00:32:03.839 --> 00:32:28.640
Yeah, on one recent social media post uh there was someone on the Field Naturalist Club of Victoria Facebook page asking for advice to get into this career, and I can't remember it was it might have been uh uh Greg Mueller uh responded you're better off getting a day job as a plumber and working two days a week and spending the rest five days volunteering in this environment.
00:32:28.880 --> 00:32:30.799
And there's a lot of people that do that too.
00:32:30.960 --> 00:32:31.599
Hello, how are you?
00:32:31.920 --> 00:32:33.759
G'day good, what are you finding?
00:32:34.000 --> 00:32:41.599
Oh, we're just having a walk down memory lane here, looking at uh some of the biodiversity in Greswell Forest in the Nature Conservation Reserve.
00:32:41.680 --> 00:32:51.680
Yeah, and Ben Cullen here, he's a podcaster, and because I've had many years of working in this field and used to work on this patch in the La Trobini days, yeah.
00:32:51.920 --> 00:32:56.000
Uh he's we're having a conversation, a recorded conversation, I must warn you.
00:32:56.160 --> 00:32:56.640
Oh yeah.
00:32:56.880 --> 00:32:59.920
Yeah, you might be a feature in it now.
00:33:00.799 --> 00:33:02.640
Have you been walking in this area a lot?
00:33:02.960 --> 00:33:05.920
Uh yeah, I discovered it during COVID.
00:33:06.000 --> 00:33:07.759
I grew up in Rosanna.
00:33:08.400 --> 00:33:16.799
We used to ride our bikes around in what was Mont Park then, but I wasn't really aware of this area.
00:33:17.039 --> 00:33:24.559
Um but since COVID I've been coming here pretty regularly and I really enjoy this little area.
00:33:25.440 --> 00:33:31.440
Um and I do a little bit of weeding in here, and I'm just looking and needs a bit more weeding.
00:33:31.759 --> 00:33:36.640
We were just talking about the exact same thing about the value of people doing that little bit of weeding, yeah.
00:33:36.880 --> 00:33:38.400
So assisted regeneration.
00:33:38.880 --> 00:33:40.079
Yeah, yeah, yeah.
00:33:40.160 --> 00:33:43.279
And I've worked in bush regeneration for 20 years.
00:33:43.680 --> 00:33:44.559
Oh wow.
00:33:44.880 --> 00:34:07.839
Can I hit you with a real basic question, or perhaps it's a hard question, but for people to try and understand why is it so important to protect patches like this, particularly around Greater Melbourne, there's little patches left, and some are at risk today, some may be at risk tomorrow, but why is it so important to protect patches like Greswell Forest that we're in right now?
00:34:08.159 --> 00:34:17.760
Look, some of people used to complain about you know the urban environment conservation movement as being misplaced, you know, there's millions of hectares out there, why are you borrowing this?
00:34:18.400 --> 00:34:26.639
And now we're seeing the emerging science, you know, by people at RMIT and University of Melbourne, urban ecology.
00:34:26.960 --> 00:34:33.599
We're seeing, you know, people like Professor Sarah Beckase, her team, Jacina Humphreys, new project she's working on.
00:34:34.079 --> 00:35:05.199
And we're now learning that that theoretical ecology, that single large reserves were more important than smaller ones, and the emerging evidence is that a whole lot of smaller nodes of biodiversity can be important habitat and note right, and even though they may not appear contiguous, like there was a lot of stuff done on wildlife corridors, a lot of it in West Australia, etc., and so on.
00:35:05.360 --> 00:35:12.960
Uh people write popular books like Roll and Breck with what wildlife corridors, the team saunders and all that in West Australia.
00:35:13.119 --> 00:35:29.840
And now the emerging science is that all these little reserves in the Melbourne area that we've been fighting for, or that we've been parochially uh consistently volunteering in, all these various French groups, are actually important nodes of biodiversity.
00:35:32.000 --> 00:35:39.440
So having and at a time of change, remnants are very important.
00:35:39.760 --> 00:35:54.000
Which gets me back to my earlier criticism, how many consultants have written off small remnants simply because they've been damaged goods without seeing their full potential under appropriate management?
00:35:54.239 --> 00:35:57.360
And appropriate management isn't necessarily more expensive.
00:35:59.199 --> 00:36:04.800
It's not about just seeing the moment in time, it's about seeing the potential and the opportunity within that.
00:36:05.199 --> 00:36:07.920
Yeah, and the same goes for the big forest too.
00:36:08.000 --> 00:36:08.639
Yeah.
00:36:09.199 --> 00:36:13.760
What are some of the special things around here in terms of invertebrates, mammals?
00:36:13.920 --> 00:36:18.800
What are what are what are some of the exciting things that uh exist in this place?
00:36:19.599 --> 00:36:22.960
Well, one of the most exciting things that's made a comeback.
00:36:24.880 --> 00:36:35.679
Back when I was a volunteer in the early 80s, the late Rod Foster would say there were sugar gliders somewhere in the hospitals near the big sugar gums.
00:36:36.880 --> 00:36:42.079
Never saw them, hadn't been detected, but he reckons they had been.
00:36:42.159 --> 00:36:43.599
I'm not sure who else knew about them.
00:36:43.679 --> 00:36:45.679
I think Cam Beertz might have known about them.
00:36:46.320 --> 00:36:52.960
Anyway, back in the 90s when I was working there, we got this federal money unemployment scheme.
00:36:53.280 --> 00:36:56.079
We employed these 25 long-time unemployed.
00:36:56.320 --> 00:36:59.760
You think that's a big task in its own right, but we did.
00:37:00.079 --> 00:37:09.119
And between Bruce Smith and Chris Robbins, who was employed as a team leader for that project, and Adrian Daniel, who was Dr.
00:37:09.199 --> 00:37:22.400
Adrian Daniel, our you know, uh our Nazi professor, our sort of ecologist who was the education arm of our uh department, they went about uh devising a nesting box for sugar gliders.
00:37:22.800 --> 00:37:23.519
Specifically.
00:37:23.840 --> 00:37:24.320
Yeah.
00:37:24.719 --> 00:37:45.599
And so Bruce came up with Chris Robbins, this box where there was a spout, so birds couldn't get in and use it, like we had issues with uh common minor and other things, uh with a hole too small for any of the possums.
00:37:45.920 --> 00:37:50.400
Instead of the hole being at the top, the hole was at the bottom, so they went up the spout and into the chamber.
00:37:51.280 --> 00:37:53.519
And so that's become the bee's knees.
00:37:53.599 --> 00:37:58.400
It's the nest box that gliders have been known to leave their natural homes to move into.
00:37:58.639 --> 00:37:58.880
Okay.
00:37:59.440 --> 00:38:00.239
The upgrade.
00:38:00.639 --> 00:38:04.079
So by 96 we started testing these various things.
00:38:04.400 --> 00:38:08.719
Gliders turned up using them at La Trobe.
00:38:08.800 --> 00:38:09.599
Yeah, great.
00:38:10.159 --> 00:38:13.840
Anyway, so the population started getting busters.
00:38:13.920 --> 00:38:17.760
We were able to show people at night, whatever we knew, these insectivores, whatever.
00:38:18.000 --> 00:38:21.119
They were even detected, even before the Mr.
00:38:21.280 --> 00:38:28.639
Boxes got there, in a survey of surplus land in the Laurundel Hospital site at the north end.
00:38:29.119 --> 00:38:30.960
So uh, who was it?
00:38:31.039 --> 00:38:39.440
It was Lincoln Kern from practical ecology, employed one of the naturalists I knew, Bob Taylor, and they found them up in this little grassland patch.
00:38:39.519 --> 00:38:43.679
You talk about small patches at the north of Laurundel Hospital near Pliny Road.
00:38:43.840 --> 00:38:45.199
And they found gliders up there.
00:38:45.280 --> 00:38:47.440
Yeah, and they found more at the south end.
00:38:48.719 --> 00:38:52.880
And a couple of years later, someone found one dead on Pliny Road.
00:38:52.960 --> 00:38:55.199
This is the multiple duplicated Pliny Road.
00:38:55.280 --> 00:39:01.280
So they had been potentially moving between Bundura Park and things in low densities.
00:39:01.519 --> 00:39:04.800
Anyway, so we didn't rolled them out, we started sold them.
00:39:05.119 --> 00:39:08.320
Everyone, the people started putting them up in the bush, they became a survey tool.
00:39:08.480 --> 00:39:16.079
Gliders and Fascagales and Yellowfoot endocrinists would move into them, so you can they could even be used to detect the presence of things.
00:39:16.960 --> 00:39:20.880
Anyway, I get this call from Rob Ewell from Land Care Victoria.
00:39:21.119 --> 00:39:25.840
Rob was a you know really good supporter of urban forestry, conservation, etc.
00:39:26.320 --> 00:39:31.119
He goes, George, I got this pro I've got some people, some money, and they want to do a project.
00:39:31.199 --> 00:39:32.639
They're from the Bank of Melbourne.
00:39:32.880 --> 00:39:34.320
Can you think of a project?
00:39:35.599 --> 00:39:37.360
And I thought, you know, disgust the phone.
00:39:38.079 --> 00:39:39.119
It's gotta happen then, it's gotta happen.
00:39:39.519 --> 00:39:42.400
And 40 people, I've got a project.
00:39:42.800 --> 00:39:43.760
Crazy idea.
00:39:44.320 --> 00:39:53.039
We got this glider population down at La Trobe, and we're managing Gresel Habitat Link and Gresel Forest, but no gliders.
00:39:55.519 --> 00:39:57.039
It had to happen in a weekend.
00:39:57.360 --> 00:40:12.719
We put up 40 nesting boxes from the back of La Trobe along Main Drive, across near the Gresle Grange Lakes, which we were co-managing, parts of the Strath Island Gulf Course habitat link all the way up to the northwesternmost corner of Gresel Forest.
00:40:13.280 --> 00:40:14.559
40 nesting boxes.
00:40:14.800 --> 00:40:15.280
Wow.
00:40:16.400 --> 00:40:26.000
Anyway, by the following year, we got up on the ladders, had a look inside, 50% of them had been used.
00:40:26.159 --> 00:40:29.760
You saw the telltale glider things, and the couple we found them in.
00:40:30.639 --> 00:40:37.039
Within a year to a year and a half, we're finding them in Grasel Forest.
00:40:38.960 --> 00:40:45.679
Anyway, two and a half years later, down in that grassland patch, we're doing a little ecological burn.
00:40:48.079 --> 00:41:03.920
Lo and behold, two years later, gliders had made it down there, and in this little burn, a glider leaps out of the shittiest little tree that you can imagine, cleared out whatever.
00:41:04.800 --> 00:41:05.840
We think, shit.
00:41:07.360 --> 00:41:19.280
Then some years later, a group down at Friends of Salt Creek Rose on the parklands, they turned up there, and Professor Mike Clark lives down there, and he was fine.
00:41:20.000 --> 00:41:21.440
So they turned up there.
00:41:21.679 --> 00:41:24.960
And this is all because of this Nest Box comeback.
00:41:25.280 --> 00:41:25.920
So there's hope.
00:41:26.639 --> 00:41:27.280
Yeah, there's hope.
00:41:27.519 --> 00:41:27.920
There's hope.
00:41:28.239 --> 00:41:29.199
Can we fix it?
00:41:30.400 --> 00:41:31.280
We can try.
00:41:31.519 --> 00:41:32.400
We can try for sure.
00:41:32.639 --> 00:41:34.079
We can go down trying.
00:41:36.079 --> 00:41:44.639
Oh, by the way, one of the things that's returned to Melbourne area, which was absent in the early 80s started, is common bronze wing pigeon.
00:41:44.800 --> 00:41:45.440
Yeah.
00:41:46.239 --> 00:41:51.199
Now, most of their diet is hard seeds, like wattle.
00:41:51.360 --> 00:41:57.760
So you think of that 70s, all those employment programs, planting wattles up and down the Darbin and everywhere else.
00:41:58.239 --> 00:42:08.880
Our tolerance of wattles, our planting wattles, our encouragement of wattles in re-vegetation areas, and voila, bronze rings made a comeback.
00:42:09.440 --> 00:42:23.039
And so I owe I owe their recovery or their recolonisation element to the population of wattles and wattle seed, seed bank that they're constantly picking up.
00:42:23.360 --> 00:42:32.880
But I saw another thing a few years ago, one cherry ballard at a trobe laid in fruit, full of bronze wings.
00:42:33.280 --> 00:42:33.760
Really?
00:42:35.119 --> 00:42:42.000
So they were feeding on the ripe cherry ballard fruit, which also has a hard seed.
00:42:42.239 --> 00:42:55.280
Now pigeons have a crop, so they ingest little pebbles, stone gravel, and they use that to scarify, to break up the seed, which they then digest.
00:42:56.159 --> 00:43:09.199
So I suspect that the recovery of cherry bellite has followed the recovery of bronze wing pigeons in the northern Melbourne area.
00:43:10.079 --> 00:43:23.519
And the recovery of bronzewing pigeons followed the recovery of wattles and having a mass unseen resource of wattle seed on the ground.
00:43:24.000 --> 00:43:26.880
Wow, that's that blows my mind.
00:43:26.960 --> 00:43:33.119
And oh it's still that same thing of thinking what relationships do we not know about?
00:43:33.280 --> 00:43:42.320
What what potential is there for us by supporting indigenous vegetation to rehabilitate the habitat for things to come back?
00:43:42.559 --> 00:43:47.360
And having the patience for things to start for for things.
00:43:47.920 --> 00:43:50.320
Well, we're working with nature, not against it.
00:43:50.480 --> 00:43:50.800
Yep.
00:43:50.960 --> 00:43:53.840
We've got to remind ourselves can we work with nature?
00:43:54.400 --> 00:43:59.840
If someone's feeling helpless and want to do something about nature, they're keen to learn and they're keen to get out there and do something.
00:44:00.159 --> 00:44:02.159
Something, what would you encourage them to do?
00:44:02.480 --> 00:44:05.679
Look, it's a big dive to get involved in an existing group.
00:44:06.239 --> 00:44:11.440
But you may consider a course that's been run in across Melbourne and in some rural areas every year.
00:44:11.679 --> 00:44:14.960
Nature Should's course is a really good one.
00:44:15.360 --> 00:44:16.639
I'm wearing the shirt today.
00:44:16.800 --> 00:44:17.360
Oh yeah.
00:44:19.599 --> 00:44:25.679
Because I think it it has introduced people that I don't already meet in these long established groups.
00:44:25.760 --> 00:44:26.400
Yeah.
00:44:27.039 --> 00:44:35.679
And people turned up, so two people that had never been to a working bee after the recent course at uh Hume, Merribeck, and Mooney Valley.
00:44:36.000 --> 00:44:42.079
I get this call on Saturday morning because I'd shared the information about the Friends of Organ Pipes, which is a well-established group.
00:44:42.880 --> 00:44:45.360
And they said, Oh, we're in this car park and Dunny.
00:44:45.519 --> 00:44:46.800
Do you know where this work bee is?
00:44:47.119 --> 00:44:52.800
I said, No, I don't, but let me make a call and um I'll put you in touch with uh someone I know.
00:44:52.960 --> 00:44:59.840
And I um had Robert Irvine's number, passed it on to them, they managed to phone it, found their way to the work and bee.
00:44:59.920 --> 00:45:03.199
Anyway, the Friends of Organpipes National Park sent me their newsletter.
00:45:03.360 --> 00:45:08.000
Next newsletter I got last this week, there are their faces joined into this group.
00:45:08.800 --> 00:45:14.239
So Harumi is new to Australia, from Japan, whatever, she's up there doing this stuff.
00:45:14.480 --> 00:45:21.199
So I think Nature Stewards is an ideal course for those people who aren't already into it.
00:45:21.440 --> 00:45:29.760
You want to take it to the next level, right, and you're a volunteer, whatever you found your way into some groups, you do the habitat conservation and management course.
00:45:30.320 --> 00:45:37.119
Where there's both hardcore volunteers and industry people alongside the course.
00:45:37.840 --> 00:45:41.760
And what has this connection with nature done to you personally?
00:45:41.840 --> 00:45:43.280
What's it meant to you?
00:45:43.679 --> 00:45:46.639
Oh look, it's uh it's an ongoing connection.
00:45:46.719 --> 00:45:49.760
I mean, I'm an immigrant to this country.
00:45:50.000 --> 00:45:56.000
When we came out, uh even though it was only a toddler, it was completely different.
00:45:56.239 --> 00:46:02.960
We you know, we we grew up, well we were growing up, in a mountain village in the Palaponnese.
00:46:03.679 --> 00:46:07.760
Uh village that had no electricity, no plumbing to every house.
00:46:07.920 --> 00:46:12.159
There was one village spring that mum would go fill water containers to.
00:46:13.039 --> 00:46:16.079
And mum was like this crazy naturalist.
00:46:16.400 --> 00:46:19.440
She knew every plant and animal, every weed, every whatever.
00:46:19.679 --> 00:46:24.960
She worked hard, she worked hard during the war years, during the famine, during the civil war, whatever.
00:46:25.360 --> 00:46:28.079
Dad was a bit older, he'd lived through all that.
00:46:28.480 --> 00:46:34.480
And here we were in industrial Yarreville, surrounded by factories, fumes.
00:46:35.599 --> 00:46:52.320
Every summer night you'd open your window, and depending which way the breeze was blowing, you'd get smorgans, the tannery, you know, Australia Carbon Black, ICI, Petrol Refineries Australia, Odors from the Maverick, whatever.
00:46:52.800 --> 00:46:54.719
Could Island, you name it.
00:46:55.360 --> 00:46:58.159
And they and they hated it.
00:46:59.519 --> 00:47:03.920
And then we started going on picnics in family groups, people from our village.
00:47:04.320 --> 00:47:07.679
Dad got his uh station wagon back in 1972.
00:47:08.000 --> 00:47:10.159
That was the freedom machine.
00:47:11.280 --> 00:47:14.320
Every weekend there'd be a picnic somewhere out west.
00:47:15.039 --> 00:47:24.239
We'd jump in the car, you know, a hamper, maybe another family, kids in the back, two families to a station wagon, go out and have a picnic.
00:47:24.800 --> 00:47:25.519
They loved it.
00:47:25.599 --> 00:47:29.760
There were places like Jeruard Gorge, you know, New Anthony's cutting.
00:47:29.920 --> 00:47:35.119
I've got photos from the 70s there with mum and dad at that historic bridge down by the creek.
00:47:35.360 --> 00:47:38.960
We'd go in search of lion parks that we couldn't afford the tickets to.
00:47:39.760 --> 00:47:44.079
You know, we'd end up at Melton Reservoir, we'd end up at Werrib South, we'd buy produce.
00:47:44.719 --> 00:47:47.119
And so we were out in nature all the time.
00:47:47.679 --> 00:47:50.800
And then we had some relatives with Mitsu Rosanna.
00:47:50.880 --> 00:48:02.639
And once you got on the east side of the city, you could drive almost this uninterrupted greenery along the Yarra Boulevard to the back of uh Heidelberg and the Yarrow there to visit them in Rosanna.
00:48:02.880 --> 00:48:04.400
Parks everywhere.
00:48:04.639 --> 00:48:06.079
And so we just started getting out.
00:48:06.400 --> 00:48:09.039
And my mother, who's 91 now, still loves.
00:48:09.519 --> 00:48:20.719
They moved to Heidelberg in the in 1992, uh 82, 83, and they've got a huge green place, and they've got indigenous plants and garden for my influence.
00:48:20.960 --> 00:48:24.159
And yeah, it's just part of a natural transition.
00:48:24.400 --> 00:48:32.480
And when I um started inquiring things when I was in the university age, I was the first non-English kid at some of these conservation groups.
00:48:32.639 --> 00:48:33.280
Oh really.
00:48:36.480 --> 00:48:39.519
Yeah, so I I found a natural home there.
00:48:39.679 --> 00:48:41.440
There were some great old mentors.
00:48:41.599 --> 00:48:54.000
One of the things I mentioned in uh the 90s, I got this grant to do all the woody weeds in this section of the salt creek from here all the way down.
00:48:54.159 --> 00:48:54.639
Wow.
00:48:55.679 --> 00:49:10.800
Either side of the creek and its various Anna branches was like this 20-foot deep patch of blackberries with hawthorns in it, some cotoniastas, some prunus, you know, and all that sort of thing.
00:49:10.960 --> 00:49:19.440
And we got into it on a big scale, like even this lamandra patch here had a whole lot of blackberry canes all around it and so on.
00:49:19.679 --> 00:49:21.519
Wow, and it looks so fantastic now.
00:49:22.079 --> 00:49:26.719
So these are remnant lamandras, and there was another remnant patch near the grassland area there.
00:49:26.960 --> 00:49:43.280
And this was the site of the first butterfly reintroduction project in Australia, inspired by Mike Braby, and we got the local school involved, and then Greenwood High, and there was this uh cohort of students called doing a subject called practical science.
00:49:43.360 --> 00:49:45.679
They were the non-academic stream.
00:49:46.320 --> 00:49:49.119
The kids called it veggie science.
00:49:50.480 --> 00:50:18.000
And we collected seed and propagated more laundras, and then we discovered the other patch, and we started, they were growing it in the school, and then he organized an excursion where we went out to all the places, like from Mitchum right around to you know, in an arc around Melbourne to eight different sites with school kids at the right time of year and collected eggs and larvae and brought them here and positioned them on these.
00:50:18.239 --> 00:50:18.559
Really?
00:50:18.719 --> 00:50:23.920
The Simomas Skipper butterfly exclusively grazes on Lamandra longifolia.
00:50:24.239 --> 00:50:27.760
Lo and behold, we saw butterflies.
00:50:28.079 --> 00:50:31.679
But the real test was the following year they were here again.
00:50:31.840 --> 00:50:32.480
Wow.
00:50:33.199 --> 00:50:44.719
And two years later they found at the far end of Greslin that other patch which we had liberated from weeds, and a year later they turned up at La Trove, 2.4 kilometres away.
00:50:45.039 --> 00:50:46.559
Is the butterfly still around?
00:50:46.719 --> 00:50:47.599
Yeah, yeah.
00:50:47.760 --> 00:50:51.599
So this is one of the two oldest trees in the reserve, probably 800 years old.
00:50:51.840 --> 00:50:54.079
Oh my god, that took me by surprise.
00:50:54.159 --> 00:50:57.679
We just looked one way and there's this huge tree.
00:50:57.920 --> 00:51:05.599
So this is the poster tree of you know, you see the you know, the multi-story habitat tree.
00:51:05.760 --> 00:51:15.760
But I was here with a bunch of school teachers one day, yeah, and uh they had a like a day off from teaching, but no students, you know, and in service it was like a gradual cluster of schools around here.
00:51:16.000 --> 00:51:30.000
And I was looking at them, and I was giving a talk and point out, and one of the teachers came up here and she's looking at her, and because I'm looking at her, I look here and there's something there that was jet black.
00:51:30.159 --> 00:51:32.880
Oh like almost charcoal.
00:51:34.320 --> 00:51:49.199
And I come up here and right here, this is about 20 years ago, in this little fissure was single men's corners for a gold squaddle bat.
00:51:49.519 --> 00:51:49.840
No.
00:51:50.960 --> 00:51:54.719
I think there's no better place to leave it than right at a gold squaddle bat.
00:51:54.800 --> 00:51:58.719
There's so many more stories with George, but we'll have to leave it there for today.
00:51:59.039 --> 00:52:07.039
I encourage you check him out on social media, you can keep track of where he might be doing a talk and have a look at the Nature Stewards course as well.
00:52:07.360 --> 00:52:18.480
