2016 National Tree Day planting

.

Location: Junction of Geebung and Federation Tracks (behind green water reservoir)

We will do a walk through the National Tree Day planting and some light weeding then move onto the Mickey Mouse Plant Ochna serrulata.

The planting site is looking great with trees and vines planted in 2015 now flowering and producing seed. A Sickle Leaved Wattle Acacia falcata is already hosting caterpillars of the Imperial Hairstreak Jalmenus evagoras butterfly.

.

The caterpillar is protected by “Kropotkin” ants – Small Meat Ant Iridomyrmex sp. The ants provide protection in return for sugary fluids secreted by caterpillar. Imperial Hairstreaks will only return to breed where both caterpillar food plants and the ants are present.
Kropotkin is a reference to Russian biologist Peter Kropotkin who proposed a concept of evolution based on “mutual aid” between species helping species from ants to higher mammals survive.

The combination of rain and clearing Creeping Lantana Lantana montevidensis means the Ochna is thriving and it is covered in flowers and seeds. However, the rain also means must easier to pull our either by hand or Treepopper.

Jisu is keen to meet a Koala but neither of us expected to meet a Kangaroo on the Griffith Inter-campus. This youngster was happily nestled into his substitute pouch on the wildlife carer’s lap.

On Saturday morning our Griffith Mates partners joined us at the National Tree Day planting site for some Citizen Science: doing an initial check on the nest boxes installed in July, to see if any boxes were occupied and meeting some of the local wildlife.

I led the team on an off track adventure to reach the nest boxes. While Carl operated the GoPro camera on the extendable pole the ground crew monitored on iPads using WiFi connection.

Carl became a real professional keeping the tall wobbly pole under control while he lifted the lid on each box and inserted the camera.

Not surprisingly none of the boxes had been occupied in the short time since installation. However, it is valuable to get a information on how long it takes before boxes are adopted.

Then is was back through the bush to the Lantana Busting site.

1,600 square metres of Creeping Lantana Lantana montevidensis were cleared and raked into swales on National Tree Day. Now we are doing the detail work of clearing the remaining roots to eradicate this invasive garden escapee.

There is an amazing about of wildlife among the leaf litter as well as in the trees. We disturbed a Scolopendrid centipede which I think Baoyi wanted to keep as a pet. Be careful handling centipedes as they may bite if disturbed or handled. The bite may cause severe pain and associated swelling.

Centipedes are predatory and will kill and consume a variety of other invertebrates such as spiders, molluscs, many insects, slaters and other centipedes. Prey is usually immobilised by venom injected through the fangs and then torn into pieces by the mandibles and the soft parts are eaten.

All that hard work deserves a reward. Thanks to Mt Gravatt Environment Group member Dana for the home made cakes.

Neighbours, Roger and Margaret called a short while ago. A Koala had just come down one tree and jumped across to another tree in the gully.

Looks young and definitely male.

Breeding season has started so the males will be on the move.

Koalas are particularly to dog attack when they are on the ground moving between trees. So it is important that dogs are kept on a leash when visiting Mt Gravatt Conservation Reserve.

Sunday morning 31 July and one hundred and thirteen volunteers have arrived for 2016 National Tree Day. So I took one team to tackle the Creeping Lantana Lantana montevidenses while Sue Jones organised the other team to start the planting. The teams swapped jobs after morning tea.

Creeping Lantana is a major weed threat in Mt Gravatt Conservation Reserve. Lantana competes for native plants for scarce water reserves and nutrients, physically smothers other plant and the chemicals in Lantana have a significant negative effects on native plant species.

The Lantana Busting teams cleared an amazing 1,600 square metres with one group raking the weed into long swales to manage erosion and retain water while others followed up, hand pulling the remaining roots. I explained that once the roots are removed the Lantana can be left piled up without regrowing. Slow, detailed but amazingly effective work. I showed the teams the natural regeneration of native grasses: Pademelon Grass Oplismenus imbecillis and Creeping Beard Grass Oplismenus aemulus, Tufted Scleria Scleria mackaviensis (native sedge) and Slender Grape Cayratia clematidea (native vine). Nature works 24/7 to build on our work and the forest will regenerate naturally if we clear the weeds.

Planting - 31 July 2016

Over with the planting team it was all action, lots of smiles and a big job in hand. This year the team is building on the work from 2015 National Tree Day with in-fill planting of 564 creepers, grasses, shrubs and trees to provide safe habitat and food for small forest birds, including nectar, pollen, insects and seeds. 2016 National Tree Day Planting List

Like last year, this was real cross-cultural event with the Griffith Mates Bushcare Team, Ahmadiyya Muslim Association and Alpha Phi Omega teams returning. This year we welcomed a new team representing carbon neutral energy supply company Viridian Energy Australia. Viridian team members traveled from the Sunshine and Gold Coasts to join us making a practical contribution carbon sequestration to protect our children’s future.

Kids having fun - 31 July 2016

And the kids were there digging in to build their own future. Kids love digging in dirt and look at the skill development! Let’s invite these future builders back for 2017 National Tree Day.

Morning tea - 31 July 2016

All that hard work deserves some tea and bikkies and time to learn about our native bees from Len Kann.

 

Ross Vasta - National Tree Day - Mt Gravatt Conservation Reserve

I show Ross Vasta and his son an Acacia Falcata planted in 2015 and already flowering.

Of course events like this are not possible without the strong support we receive from our local, state and federal politicians. We were pleased to welcome Ross Vasta MP, Federal Member for Bonner and Jo Kelly MP, State Member for Greenslopes.

Ian Walker MP, State Member for Mansfield and Cr Krista Adams, Councillor for Holland Park both wanted to attend but had other prior commitments.

Event supported by:

BCC Habitat Brisbane
Bulimba Creek Catchment Coordinating Committee (B4C)
Planet Ark National Tree Day
Peaks to Points Festival

supporters

An amazing event – see Stats below, and importantly it looks like 2017 National Tree Day will be even bigger with all the teams and local community members telling me they want to come back.

Stats:

115 participants including two BCC Habitat Brisbane team members

  • Three groups from 2015 returned this year, one new group and lots of locals
  • All fours groups want to return next year when I hope to hold the event at the Summit

273.5 volunteer hours

564 plants

  • 30 creepers
  • 230 grasses
  • 114 shrubs
  • 190 trees

1,600 square metres of Creeping Lantana cleared.

OWeek Semester 2 2016

It is always a pleasure to lead a guided walk with our Griffith Mates partners, sharing some of the surprising relationships between different plants and between plants and the animals that depend on them for food and shelter.

Many of the students who join the walk are international so it is a great opportunity to introduce these visitors to our unique bushland. Unfortunately no Koalas spotted this time.

Walking Acacia Way we discussed the importance of tree hollows for nesting and the curious Allocasuarina: male trees have russet (red-brown) flowers on tips of leaves and female trees have red ball flowers growing directly from the branches.

Stopping at the interpretative sign I used the QR code to bring up the online video of a Striated Pardalotte Pardalotus striatus with its “chip-chip” call on my iPhone. As soon as the birds high in the trees head the call they started to respond with their own calls.

Settlers Flax Gymnostachys anceps has an interesting history of use by indigenous people and white settlers:

“Fibres were used to make fishing line. There are records of use as string by Europeans (to bind and carry pigs by the feet).” Save Our Waterways Now (SOWN)
