Pacific Bazza - 4 Mar 13

Pacific Baza Aviceda subcristata

By: Michael Fox

You always know when a Pacific Baza Aviceda subcristata is around because all the other birds kick up a fuss although they don’t seem to be a direct threat, being more interested in stick insects.

The Pacific Baza’s favorite prey is large insects, particularly stick insects and mantids, and frogs. They sometimes eat fruit as well. Bazzas will move through the canopy, or perch and watch, then make short dives, with feet extended, to snatch prey from the foliage or from the air.  Birds in Backyards

Three of these magnificent birds have been visiting various parts of Fox Gully over the past week. While I was watching one of the Bazas flew into the trees planted in the Zone 8 restoration then landed back on the same branch to eat something long and green. I was too far away to photograph but I suspect it was a stick insect.

Squirrel Glider - A Moore - 21 March 11

Squirrel Glider Petaurus norfolcensis

By: Michael Fox

Key threats to Mt Gravatt Conservation Reserve:

Much of our work in restoring habitat in the Reserve is cleaning up damage done by easy to avoid action, like people dumping their garden waste in the bush when they could often simply put it into their wheelie bin.

Keeping our family cats inside at night takes a bit of effort. However it is still a relatively simple action that has huge benefits for our nocturnal wildlife like gliders and possums.

Gliders are one of the cutest of our Australian native animals. Sugar Gliders Petaurus breviceps and Squirrel Gliders Petaurus norfolcensis are found in Mt Gravatt Conservation Reserve. Restoration work at Fox Gully Bushcare site includes installation of nest-boxes to provide habitat for hollow dwelling animals like gliders, possums and birds.

Glider cat attack - Souther Star - 20 Feb 13

Southern Star – 20 Feb 2013 – page 8

So it was heart breaking to see the remains of a glider attacked by a domestic cat.

Sharing the story with the Southern Star is one way to help people think about doing things differently.

Another simple change we can make is to use wildlife friendly netting for our fruit trees. See article in Southern Star – go to page 8 and click to enlarge for reading. Information on wildlife friendly netting from Bat Conservation & Rescue Qld. Inc.

GPP storm damage - 5 Feb 13

Storm damage Gertrude Petty Place Bushcare

By: Michael Fox

Over the last two days I have walked the tracks in the Reserve to see what damage was done by last week’s storm. Being a mountain flooding is not a problem however we have lost a significant number of large eucalypts, a number of Casuarinas and a significant number of dead old trees (stags) which are often important habitat because of their nest hollows. A number tracks are blocked by fallen trees which will take time to clear as the Council teams prioritise clean up work.

Mountain Bike tracks

Storm block illegal mountain bike tracks

However, the storm has created some unexpected benefits for the habitat as fallen trees have blocked tracks used by illegal downhill mountain bike riders. We have had a number of reports that mountain bike riders have been seen in the Reserve so I also walked the areas that have been damaged illegal riding. I found some evidence of bike riding including clearing of logs placed by Council contractors to block tracks and minimise further erosion. So I was pleased to find a number of tracks blocked by large branches broken in the storm.

I am also heartened by seeing wildlife thriving in the post storm environment.

Shepherd’s Crook Orchid

I also found the Shepherd’s Crook Orchid flowering again at the Fox Gully Bushcare site. This is particularly important as this beautiful native orchid has been returned to the Reserve as a result of restoration work undertaken at the Fox Gully site.

Koala and Joey - Fox Gully wildlife corridor

Koala and Joey – Fox Gully wildlife corridor

Just this week the Southern Star reported that Koalas are fighting back and printed our map of sightings in Mt Gravatt Conservation Reserve.

Then on Friday night Matt Hill heard a scratching noise in the trees behind his deck. Thinking it was probably a possum he investigated with with torch picking up the glint of four eyes in the trees. He was delighted to find a Koala mum with her Joey comfortably nestled in her arms while she munched on leaves.

Koala sightings Fox Gully wildlife corridor

Matt and his family have been active supporters of our Fox Gully Bushcare restoration work and has been controlling weed trees, like Camphor Laurel, on his gully property. So, in December, he was proud to show me what looked like Koala scratches on a tree restored to the habitat only five years ago. This was an exciting find and now with this weeks photos we have confirmation that Koalas are not only active in the wildlife corridor but also breeding successfully. We also received another report this week of a Koala sighted high in a tree beside the footpath to the Griffith University Bus Station.

Ringtail Possum Pseudocheirus pereginus

Ringtail Possum Pseudocheirus pereginus

Restoration of this key wildlife corridor is now supported by seventeen property owners whose backyards include the gully and community members committed to restoring habitat for Koalas, birds, butterflies, frogs and native bees.

Restoration of the of the wildlife corridor is having a positive effect as shown by the number of Koala sighting as well as increasing other wildlife. At the top end of the gully, Roger and Margaret have a family of Ringtail Possums Pseudocheirus pereginus living in the top of staghorn ferns. Just before Christmas a mother with two babies on her back was sighted and Friday Margaret called to say the father had been disturbed from his staghorn nest when Roger was hosing.

Note his spiky hair and spiky attitude as he cleans water off his coat.

f

Common Ringtail Possum – not that common

Please be patient with these cute creatures if they eat some of your fruit. During the 1950’s Common Ringtail Possum populations severely declined in numbers. Currently populations seem to have recovered but they are at risk of attack by cats loose at night.

Unlike Brushtail Possums Trichosurus vulpecula, Ringtails tend to avoid house ceilings, preferring to nest in trees or the tops of staghorns, so they are not considered pests in suburban areas.

Southern Star – January 16, 2013

We host international students at times and today we received a note from the Japanese student who will be living with us during February. One thing she was very clear about: “I want to see a Koala.” With latest sighting, reported this week, of a Koala in a tree beside the footpath leading to Griffith University Bus Station there is an increasing chance that she will see a Koala on the way to university.

It really is fun to watch international students/visitors when they see a Koala just sitting (usually sleeping) in a tree or an Echidna walking across the track … and not a zoo keeper in sight. The most amazing experience though was watching Jian, an international student from Shanghai, when he came face to face with a Koala right on our back deck.

Southern Star – January 16, 2013

You can get involved with bush restoration,  reporting any Koala sightings on Koala Tracker or simply slowing down and reporting sick or injured wildlife to 1300 ANIMAL 24/7.

The Southern Star interview with Adrian Schrinner and Natalie Forrest is very valuable in building community awareness. However, it is not only out at Gumdale and Chandler that we need to be increasing careful if we want to have Koalas living in our backyards. We have had one Koala killed on Klumpp Road and another rescued on Creek Road after a car strike.

The outlook for Mt Gravatt Conservation Reserve is looking good with good rain forecast through to February which will greatly enhance the habitat restoration at our Bushcare sites.

We are also seeing positive signs with our wildlife. Two Rainbow Lorikeet Trichoglossus haematodus chicks have been hatched out in one of the nest boxes installed at the Fox Gully Bushcare site.

When we first confirmed the chicks had hatched we were not sure that they were Rainbows but one week on there is now no doubt as their colours develop. Click on the photo to enlarge.

We have also had another Koala report this week from Ramita Street near Ekibin Creek.

Neighbours pitch in to clear up

A 20 metre Chinese Elm Celtis sinensis creates a lot of green waste to be chipped and cleared from the gully. Neighbours Rebecca, Didier, Don and Clair pitched in to clear up the huge pile of branches.

A big clean-up needs a big chipper. Miranda loved using our Greenfield’s 8.5hp Piecemaker that virtually sucks the branches into the blades for chipping. Thanks to Southside Sport & Recreation Club who provided the grant for purchasing the chipper.

The Piecemaker is proving its value saving over $2,000 on the cost of removing the Chinese Elm, a benefit for our whole community, in particular restoration of Mt Gravatt Environmental Reserve.

Even the local wildlife is joining in the clean up. This Laughing Kookaburra Dacelo novaeguineae is hunting for worms and spiders among the leaf litter. The Kookaburras are really enjoying the restoration work as more worms, insects and spiders are thriving among the planting, mulching and logs.

Northern Jumping Spider Mopsus mormon

It is inspiring to find the variety of wildlife returning to the gully. This beautiful Northern (Green) Jumping Spider Mopsus mormonwas hunting for flies, moths or grasshoppers for lunch. Creating habitat for wildlife means we have natural pest control and over time we will hopefully tempt some of the beautiful insectivorous birds out the forest. Birds like the Striated Pardalots Pardalotus striatus and the beautiful Black-faced Monarch Monarcha melanopsiss not only add sound and beauty to our backyards, they also hunt insects like mosquitos on our behalf.

Striped Marsh Frog eggs

Another amazing find was these eggs of the Striped Marshfrog Limnodyynastes peroni in one of semi-permanent rock pools created by the return of the permanent spring.

Striped Marsh Frogs are a native ground dwelling frog with a distinctive “toc …. toc …. toc” call. To listen scroll to Calling on the Frogs of Australia web page and click “Hear it now.”

With the Chinese Elm down and the chipping finished we can now plant nine advanced Red Cedars donated by Dave and Liz, Roly Chapman Bushcare. Red Cedars (common name for a number of Toona species) are an attractive fast growing native that will help restore the gully habitat and privacy for the neighbours.

Splendid Ochre Trapezites simmomus

The Love Flower Pseuderanthemum variabile, caterpillar food for Australian Leafwing butterfly Doleschallia bisaltide, Waxflower Vine Hoya australis and Coinspot Treeferns Cyathea cooperi are all growing. The Creek Mat-rush Lomandra hystrix are thriving even with the dry weather. These Lomandara are caterpillar food for the Splendid Ochre Trapezites simmomus and Brown Ochre Trapezites iacchus butterflies as well as providing valuable erosion control in the gully.

Ready to climb

Some weeds don’t come out easily so extreme measures are required.

Dale, owner of Climb n Grind, straps on his spikes to scale this 20 metre high weed, an invasive Chinese Elm Celtis sinensis.

Chinese Elm or Chinese Celtis is a Class 3 Environmental Weed:

Starting the climb

“Thousands of small, orange berries are produced and are dispersed when eaten by birds. Celtis often grows in clay soils associated
with alluvial creek flats and gullies. It is an invader of riparian habitats …”

Sales of Chinese Elms have been prohibited for some years however this fast growing invasive weed is still growing in many backyards and spreading to neighbouring backyards as well as bushland areas like Mt Gravatt Conservation Reserve.

In 2012 Mt Gravatt Environment Group has been working closely with BCC Habitat Brisbane Officers to remove large Chinese Elms within the Conservation Reserve.

Time to relax?

Invasive weeds are one of the three key threats to the long term health of this unique Koala habitat. So it is inspiring to work with community members committed to restoration of the Fox Gully wildlife corridor and paying for removal of these weeds on their own properties.

In this case Annette has contracted professional tree climber Dale to scale the tree and to deconstruct it without damage to surrounding building or fences and with minimal damage to the restoration planting.

Walking up a vertical surface

Watching Dale operate was amazing. Having strapped on spikes and hanging an extraordinary collection of ropes, tools, even a chainsaw, from his belt Dale simply started “walking” up the side of this tree, making it look as easy as stroll in the bush.

The tree was covered in hundreds or perhaps thousands of immature berries that would have been spread by birds or washed down the gully to infect other properties or Roly Chapman Reserve and Mimosa Creek. Prior to targeting Chinese Elms for removal we would remove two or three hundred seedlings each year in each of our bushcare sites so removal of this tree is a significant boost to our restoration efforts.

November 2007 we held our first Community Planting Day.

King Parrot feeding on Brisbane Fringed Wattle

Four hundred and ten native plants represented the first big step in restoring the Fox Gully habitat.

Aside from native herbs and grasses we also planted a number of Acacia falcata and Acacia fimbrata. Acacia fimbrata, also called Brisbane Fringed Wattle, is one of the most beautiful of our local wattles and a favourite with at least one of our neighbours – read the story.

Brisbane Fringed Wattle is also a favourite of our beautiful King Parrots Alisterus scapularis who visit each year to feast on the seed pods. Watch the video to see the amazing skill in getting each seed then moving the pod along to get the next seed … and no hands needed.

Pale-headed Rosellas inspecting nest box

We had a day of inspections today with a pair of Pale-headed Rosellas checking out prospective new homes. Unfortunately they started with two boxes designed for Scaly-breasted Lorikeets. The smaller entrance diameter means the boxes are kept available for these smaller birds that are losing out on breeding sites with resulting drop in numbers.

Fortunately the Pale-headed ended up down behind Alan’s house where there is a box with a larger diameter entry.

They made it too small … let’s chew our way in.

This box looks like someone has had a go at expanding the entry size but still not large enough.

While we were walking we also noticed a pair of Rainbow Lorikeets inspecting the Owl box – designed for Boobook or Barn Owls not Lorikeets.

Too small for Kookaburra … need to find a larger termite nest.

Up the track near the big water reservoir we found two Kookaburras sitting on a branch between the new Kookaburra box and the termite nest they had been trying to hollow out. The Kookaburra box was installed because clearly the termite nest was too small the make an effective nest hollow. Hopefully today’s sighting means they are considering the new box.

Tawny Frogmouth being a dead branch

Of course there is always someone who relaxes and wonders what the fuss is about. We almost didn’t see this Tawny Frogmouth pretending to be a dead tree branch. He deigned to half open an eye to check us out then dismissed us and went back to being a dead branch.
