Mia & Camilla - Griffith Mates 1 - 23 Aug 2014

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.

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.
