- Description
- At Mount Owen Mine, rehabilitation efforts aim to reconstruct a sustainable native forest ecosystem functionally similar to Ravensworth State Forest, through which the coal mine is passing. The greatest challenge is establishing native plants on foreign substrates such as spoil, chitter and subsoil or mixtures of these, as well as using stockpiled pasture topsoil. These need to be used because forest topsoil (biologically the most appropriate choice) is in short supply. Establishment issues are being tackled by choosing hardy native plant species present in the forest, or local to the region, to initiate vegetation cover for the different plant strata. Germination trials have been carried out on selected species used in the rehabilitation seed mix to determine treatments promoting germination in the laboratory, shade house and the field. Boiling, scarification, and oven heating of the seeds had different effects on different species as is to be expected. The interaction of species with the soil replacement media, to be used in the rehabilitation site, has also given some interesting results that are species dependent.
