Our Griffith Mates partners have again provided valuable for restoration of our Fox Gully Bushcare site. At the last event for 2016 we first checked what species can now be found in the Small Bird Habitat.

Griffith Mates participated in the 2015 National Tree Day planting of the Small Bird Habitat so it was great to be able to show the increase in species diversity in just one year.

The Small Bird Habitat is an initiative to create the specialised habitat our small forest birds like Variegated Fair Wrens Malurus lamberti. These small insect eating birds are valuable partners in controlling pests in our backyards. Building an effective habitat requires attracting a diverse range of insect species to provide food.

Finding several Painted Pine Moth Orgyia australis caterpillars on site is a good excellent start.

Lydia Lichen Moth Astura lydia

We inspected the Imperial Hairstreak Jalmenus evagoras butterfly caterpillars on Sickle Leaved Wattle Acacia falcata. I explained that the caterpillars are protected by “Kropotkin” ants – Small Meat Ant Iridomyrmex sp.

We also found a Lydia Lichen Moth Asura lydia with its curious eyelash like antlers.

Other excellent signs of habitat building progress was finding seed on Sickle Leaved Wattle Acacia falcata, Native Sarsaparilla Hardenbergia violacea and Kangaroo Grass Themeda triandra which will provide food for seed eating birds.

Ochna Blitz

After inspecting the Small Bird Habitat progress we moved onto our Ochna Blitz. Mickey Mouse Plant Ochna serrulata is a deep rooted invasive garden plant with attractive red and green berries that are eaten by birds then spread into our bush habitat. The objective is to start breaking the weed cycle by collecting, bagging and dumping the seeds then poisoning the plant. Eradicating or at least reducing Ochna in the Reserve will take years but systematic clearing of smaller areas will progressively reduce the spread.

We look forward to partnering with Griffith Mates again in 2017.
