A local endangered species in Bomaderry is the Broad Headed Snake. This snake has lost its homes thanks to the bush rock industry. The nocturnal snake can only survive where there are rocks on top of rocks in sunny spots near cliff edges. Shoalhaven Landcare need to make 300 new homes out of fibre reinforced concrete to replace all the natural rock homes that have been taken from our local bushland. The students at Bomaderry High School will spend two days mixing the concrete and moulding the stones. The artificial habitats have to be just the right thickness and size for the endangered reptiles, as well as coloured to match the bushland. The concrete is coloured with natural ochres, and poured into sand moulds. The students create unique moulds in sand for the concrete, each mould having to match the known sizes of the natural rocks the endangered reptiles require. Coffee grounds are added to the sand mould before the concrete is poured in, this creates a layer of acidic organic material that mosses and lichens will colonise.
Once the artificial habitats are set, they will be trucked to areas of local bushland that have suffered from humans taking the natural rock.
This project replicates the work by Dr. Jonathan Webb who has studied the endangered Broad Headed Snake in our locality on the South Coast. For the next three years the artificial habitats will be monitored by scientists to see if we can save this local species.
