Koalas on Mt Gravatt: Who’d have thought it?

Sunday morning 4th December and John McCrystal and a friend were riding Shire Road to the summit of Mt Gravatt. John, a member of Team Fatboyz, was practicing for the Rio Tinto Ride to Conquer Cancer – August 18-19, 2012, he certainly didn’t expect to encounter two Koalas running down the road towards him!

Koalas travel 5 to 10km to find new home territory.

“They came running down the mountain and then starting running toward us on the road. They then froze in front of us started snorting, I think they were scared. We had to shoo them off the road. They then climbed the first tree they found.” John

John grew up on the side of Mt Gravatt and he had never heard of Koalas on the Mountain. I have heard from others that there have “never been” Koalas on Mt Gravatt and any animals found must have been relocated there after recovery from injury. This has always seemed to be an unlikely explanation because injured animals, including Koalas, are returned to locations as close as possible to where they were found.

Koalas on Mt Gravatt – What is the answer?

Southside Community News – Jan 2012

.

Professor Carla Catterall, Griffith School of Environment, advises that from the 1970s to the 1990s koalas were not seen in Toohey Forest, in spite of many naturalists  walking in the forest and doing ecological surveys there.  This has been a puzzle given that Koala food trees are present in reasonable numbers.  Professor Catterall suggests that Koalas may have previously been in the forest then extirpated (local extinction) in the early 20th century.

Koala fur industry

.

Hunting for Koala pelts was a major industry after European settlement. Who would want to wear Koala fur? The Koalas I have handled didn’t exactly feel luxurious and soft. Glenn Fowler’s 1993 report, “BLACK AUGUST” Queensland’s Open Season On Koalas in 1927 available at Australian Koala Foundation site, provides and insight into this unlikely trade.

‘Although (fortunately for the koala) not highly valued, the koala’s thick soft fur soon acquired the reputation as being a particularly effective insulator against the cold – ideal for protecting the human body from “the icy blasts of winter in Northern Canada and Europe”. Koala fur was renowned for its ability to withstand any amount of hard usage.’ Fowler, 1993.

For me, the really sobering thing was realising that as recently as 1927 the Queensland Government approved a six month open season on Koalas. More than 500,000 Koala pelts were delivered to market – a huge impact given the number of pelts that would have been unusable and the joeys left to starve.

Koalas returning to Mt Gravatt

Koala sightings Mimosa Creek Precinct

.

Nature is now giving us a second chance with Koalas now breeding successfully in the Reserve and increasing sightings particularly around our Fox Gully Bushcare site: Mimosa Creek Precinct.

Griffith University researchers believe that there is more functional linkage between Toohey Forest and other forest areas in the western past of Brisbane than might easily be assumed: in spite of the hazards of roads. We have one sighting of a Koala successfully crossing the Motorway onramp however the recent death of a Koala hit by a car on Klump Road highlights the need for safe wildlife corridors connecting Mt Gravatt Reserve with Mimosa Creek, Roly Chapman Reserve and Toohey Forest.

Cathyrn Dexter, Griffith University, is leading a project with Main Roads Department which aims to create permeable landscapes that will allow animals to move around without having to interact with roadways: safer for wildlife and drivers.

We will draw on Cathyrn’s research as we restore the Fox Gully wildlife corridor to improve the chance for Koalas to move safely across Klumpp Road. In the short term we are working with Cr Krista Adams to have Koala crossing signs erected on Klumpp Road. While the active police presence is likely to have much greater impact on speeding, Koala crossing signs will be a valuable community education tools building awareness that nature is returning a special animal to our urban bushland environment.

Living on the edge of Mt Gravatt Reserve we often have butterflies visiting our yard. Today I videoed this Cabbage White Pieris rapae feeding on the Thyme flowers in our rose garden.

Michael Braby in Butterflies of Australia describes this erratic flight and feeding behaviour. This butterfly is using his proboscis or haustellum, a hollow straw-like tongue, to feed on nectar. The proposcis in normally kept rolled and extended for feeding.

Our Pollinator Link initiative, described in my Southside News article, aims to bring more butterflies to suburban backyards.

If you have citrus trees you may find the leaves being eaten by the caterpillars of Orchard Swallowtail Papilio aegeus butterflies.

2011 has been a big year for Mt Gravatt Environment Group so to receive two top awards from Bulimba Creek Catchment Coordinating Committee (B4C) is a very satisfying way to round off and prepare for 2012.

I was personally awarded Environmentalist of The Year which is a great honour coming from some of the most committed and experienced environmentalists I have ever met.

Mt Gravatt Environment Group was awarded Bushcare Group of 2011 which truly reflects the extraordinary work of a large number of community members but particularly our Bushcare coordinators:

Our achievements also build on the strong support of Kate Flink, our BCC Habitat Brisbane Officer, the B4C team, Ann Moran and Alan Moore who presented our Environmental & Photography Workshop, community groups like Mt Gravatt Men’s Shed, McGregor Lions Club, Southside Sport and Recreation Club and Mt Gravatt Historical Society, Griffith University, BCC Mt Gravatt Library and local politicians Phil Reeves MP and Cr Krista Adams and their excellent staff.

Now it is time to take a holiday and get ready for an even more extraordinary 2012.

Saturday 26 December – Morning tea after a morning pulling weeds and planting at Gertrude Petty Place Bushcare. A simple happy and appropriate way to celebrate another successful year.

Our Gertrude Petty Place team have been steadily cleaning up the gullies and doing restoration planting. To October the team has put in 211 volunteer hours and planted 249 native plants most of which were propagated by the team members themselves.

Female - Spotted Pardalote - Photo A Kittila

Missing from the photo are Sheamus O’Connor who organised the Mt Gravatt SHS planting at the start of the Summit Track and Brett Dugdale – Rover Street Bushcare … and Kate Flink our wonderful BCC Habitat Brisbane Officer who was taking the photo.

It is important to note that 211 volunteer hours is only the time spent on-site. As well as that time our volunteers spend time on propagation, talking to school and community groups, applying for grant funding, preparing track guides and coordinating corporate groups like Conservation Volunteers Australia and McGregor Lions.

Others generously contribute information and photos of wildlife like the Spotted Pardalote Pardalotus punctatus and Black-faced Monarch Monarcha melanopsis. Andrea has added three bird species to our Flora & Fauna of Mt Gravatt Reserve bringing our count to fifty one bird species in the Reserve.

CVA team roll up weeds on Mt Gravatt

Removing weeds with Tree Popper

By Susan Jones

Last Saturday, Conservation Volunteers Australia (CVA) brought a corporate group of twelve young volunteers to assist Mt Gravatt Environment Group with weed removal at the entrance to the Summit Track.   Their main targets for the day were Creeping Lantana Lantana montevidensis and Mickey Mouse Plant Ochna serrulata.

Group leader, Fabian was interested in trying out our Tree Popper on the Mickey Mouse Plants, as he had not seen one of these used before.  The tool is placed around the main stem of the ground at ground level, the pincers are closed firmly and the tool levered towards the user.  With very little effort the weed emerges from the ground with its deep tap-root intact.

Whilst the blokes were grappling with Mickey Mouse Plants, the girls were rolling up Creeping Lantana like a carpet.  After shaking off the dirt, the ‘carpet’ was laid out to dry.  Once the materials has dried out, it will be returned  to the earth as mulch.

Rolling up Creeping Lantana

Thanks to Conservation Volunteers Australia  and the volunteers for a great day’s work!

Conservation Volunteers organise groups of local volunteers, often corporate groups, as well as volunteers from around Australia, New Zealand and the rest of the world.

The researchers have finshed and the report is now available to help us plan restoration of our wildlife corridors and provide scientific evidence to support funding applications to support implementation of our Mimosa Creek Precinct Landscape Plan.

The report was prepared by Biodiversity Assessment and Management Pty Ltd with funding provided by the Department of Environment. Click on link to download a copy Mimosa Creek Precinct Flora & Fauna Assessment Nov 2011

Koala sightings Fox Gully

The report assessed the potential for the development of three potential wildlife corridors linking Mt Gravatt Reserve with Mimosa Creek. Koalas are breeding on Mt Gravatt and already starting to move into the Fox Gully corridor, see map, so our initiatives like our Community Gully Day are increasing important.

This research and report was made available through the strong support provided by Bulimba Creek Catchment Coordinating Committee (B4C), Griffith University School of Environment and EcoCentre, Butterflies and Other Invertebrates Club (BOIC), and Cr Krista Adams.

Particular thanks to our local state MP Phil Reeves and past Environment Minister, Hon Kate Jones who supported our application for research funding.

Blue Banded Bees and Variegated Fairy Wren

A Blue Banded Bee – Amegilla cingulata getting nectar from one of our special Bottle Brush Grass Tree – Xanthorrhoea macronema.

It is particularly pleasing to photograph my first Blue Banded Bee today because I am currently writing an article on Pollinator Links for the Southside Community News. Pollinator Links are a form of wildlife corridor that has potential to work in our fragmented urban landscape and they are a key strategy in our Mt Gravatt Showgrounds Precinct Landscape Plan.

Blue Banded Bees are an Australian native bee and an important pollinator of our food crops like tomatoes. Some plants will only release pollen when the flower is vibrated rapidly – buzz pollination.

The importance of these and other native buzz pollinators is highlighted by the fact that the commercial honey bee – Apis mellifera, cannot perform buzz pollination. The Blue Banded Bees website cites significant benefits for crops such as tomatoes, kiwi fruit, eggplants and chillies. Blue Banded Bees are thought to improve yields in Australia by at least 30% overall.

I also managed to photograph one of our beautiful Variegated Fairy Wrens Malurus lamberti. A male in full breeding colour. There was a least one female around but she would not sit still for a photo. These delicate little birds like scrubby areas where they are safe from predators, often Lantana. So part of our bush restoration work is ensuring there is that there is replacement habitat established before we remove large areas of Lantana. As we establish Pollinator Links we aim to bring special birds like these back into our community backyards.

Mt Gravatt Showgrounds Precinct Landscape Plan

Showgrounds Precinct - click to enlarge

Mt Gravatt forms an inspiring backdrop for Showground events like last Sunday’s Green Heart Fair and the Showgrounds link our mountain heart with our community in a way unique in Brisbane and possibly the world.

The Mt Gravatt Precinct Landscape Plan aims to build those community links as an integral part of the environmental restoration of this important and diverse Australian bush habitat only 10 kilometres from Brisbane CBD.

Click here to download the plan: Mt Gravatt Showgrounds Precinct Landscape Plan – ver 3.0 email

The plan is based on our vision for the restoration of Mt Gravatt and complements the Mimosa Creek Precinct Landscape Plan.

Pollinator Links, a key part of the Landscape Plan, will link Mt Gravatt Reserve with Bulimba Creek via the Showgrounds and Jo’s Creek. Pollinator Links are an innovative approach to creating wildlife corridors through the fragmented urban landscape. These urban ecological corridors will allow pollinators such as Sugarbag Stingless, Leafcutter and Blue-banded bees (all recorded on Mt Gravatt) to move between fragmented habitats.  Birds like Grey Fantails and Golden Whistlers, butterflies like Orchard Swallowtails and Tailed Emperor will also utilise these pathways, thereby returning these species to our backyards.

While the environment is the key focus building and maintaining long-term financial and community commitment requires creation of shared value through identification of business opportunities and community benefits derived from habitat restoration. The Showgrounds – Mountain Link Track is one example of shared value creation – creating easier access to mountain walking tracks and opportunities for “King of the Mountain” type tourism events based at the Showgrounds.

Koala Mum and Joey on Mt Gravatt

We know that Koalas are breeding on Mt Gravatt. We are getting regular reports of sightings from all around the mountain and I have even woken to find a young male climbing onto the deck at night. However, today, our Rover Street Bushcare co-ordinator, Brett Dugdale, shared something I have never seen before: a mother and joey together.

In Mt Gravatt we live only ten kilometres from Brisbane CBD and we have Koalas in our “backyard”. As a community we are stewards of a truly unique piece of Australian bush habitat.

I am honoured to know Brett. He is not only passionate about protecting and restoring the mountain habitat; he also brings a wealth of practical restoration experience gained working with Bulimba Creek Catchment Co-ordinating Committee (B4C).

Brett notes that the Brisbane City Council fox eradication program – seven foxes have been removed from Mt Gravatt Reserve in the last twelve months – is having a positive effect on the mountain wildlife. However, as Koala numbers increase,  conflict with domestic pets will become an increasing problem: a young Koalawas attacked by a dog in a local backyard last week. That lucky Koala was OK after being checked out by RSPCA vets and returned to the mountain.

Please keep your dogs on-leash when walking in the Reserve and of course carry bags for dog droppings. Koalas tend to avoid areas where they can smell dog droppings so if we want to encourage Koalas we need to clean up after our dogs.

If you find any injured wildlife in the Brisbane area you can call the BCC Wildlife Ambulance – BCC Call Centre 3403 8888.
