Amanda launched her attack on Ochna

By: Michael Fox

Our Griffith Mates friends returned for Fox Gully Bushcare last Saturday.

The job for the day was attacking our three most invasive weeds.

Amanda launched her attack on the Mickey Mouse Plant Ochna serrulata. Ochna is a garden escapee that spreads when birds eat the bright coloured berries then fly into the bush, then spreads quickly as the shrubs get established.

Ochna is a particularly difficult weed to remove because of the deep tap-root.  The Treepopper is the ideal weapon attack these woody weeds and you get a great sense of satisfaction as you pull these weeds out roots and all, and no poison needed.

Emmanuel attacks Asparagus Fern

Emmanuel launched his attack on another garden escapee – Asparagus Fern Asparagus aethiopicus – again spread by birds eating the red fruit.

Emmanuel used a Cyclone 2 Prong Hoe to remove the Asparagus Fern before trimming off the leaves and roots and collecting the crown for removal off-site. The crown is the brain of the Asparagus Fern, so removal means the plant will not regrow.

Tomorrow identifies Basket Fern from her visit to Cairns

It is a real pleasure to share the forest with our international visitors. I was particularly impressed when Tomorrow identified Basket Fern Drynaria rigidula.

With Tomorrow digging using the 2 Prong Hoe and Emmanuel on the Treepopper the team managed to pull out the largest Ochna trunk I have seen.

Sienna, Amanda, Ho Yi and Sau To attacked the Creeping Lantana Lantana montevidenses again a garden escapee spread by birds eating the purple fruit.

The Lantana team cleared a large area of weed, raking it into swales to compost, control water runoff and reduce spread of weed seed.

Stick Case Moth - 26 Sept 2015

Stick Case Moth Clania lewinii

.

A successful morning for all. Amanda filled her five specimen containers with a bush cockroach, butterfly and other insects for her university collection.

We also added Stick Case Moth Clania lewinii to our species list for the Reserve.

The shape and construction materials of a case moth’s portable home allow identification of the moth species. Stick Case Moths build their case moth bags using sticks of similar length. Similar bags are built the Faggot Case Moth Clania ignobilis with one or two longer sticks.

Meeting the locals – Golden-tailed Spiny Ant nest

How better to finish the day?

I showed how turning over a couple of rocks could expose a whole new world.

Mia & Camilla dressed for action

By: Michael Fox

I was very proud of our Griffith Mates partners today. Rain and mud did not stop Camilla and Mia.

The rain meant it was unsafe to work removing Fishbone Fern on the steeper areas of the gully, so our focus was restoring and strengthening the silt filters along the Farm Fire Trail.

The silt filters are proving very effective. Simon Fox, our BCC Habitat Brisbane coordinator, is impressed with our simple low-tech solution to reduce erosion. Recycled deck timber is used to make stakes and timber barriers to hold the mulch forming the silt filter.

Muddy silty water

The filters slow muddy water so the silt has time to settle out while the water filters away. In some areas up to 100mm of silt has been captured and stopped from flowing into Mimosa Creek.

Golden-tailed Ant nest - 23 Aug 2014

Golden-tailed Spiny Ant nest

Camilla and Mia were fascinated by what we found while we were looking for rocks to help manage erosion. The first two rocks we turned over we found ant nests so we carefully restored their home.

The first nest was a Golden-tailed Spiny Ant Polyrhachis ammon. When they named it spiny they were not kidding. Aside from the spines over the head and caster (tail) this ant has extraordinary sharp horns on the body.

Under the second rock we found a new ant to add to the species list for the Reserve. Black-headed Strobe Ant Opisthopsis rufithorax.

Enough work. Time to get out of the rain, have a hot drink and warm up.
