Rebuilding Sustainable and Functional Biodiversity following Coal Mining. Open-cut mines are a significant land-use in Australia and generate considerable GDP. Poor management prior to mining has caused much topsoil to be lost and microbes vital to sustainable nutrient cycling reduced to <10% that of a sustainable forest. To address this problem we are developing a rehabilitation model using Mount Owen open-cut coal mine which passes through a Upper Hunter forest. This project will discover ways ....Rebuilding Sustainable and Functional Biodiversity following Coal Mining. Open-cut mines are a significant land-use in Australia and generate considerable GDP. Poor management prior to mining has caused much topsoil to be lost and microbes vital to sustainable nutrient cycling reduced to <10% that of a sustainable forest. To address this problem we are developing a rehabilitation model using Mount Owen open-cut coal mine which passes through a Upper Hunter forest. This project will discover ways of utilizing microbe-derived nitrogen vital to a sustainable supply for native forests. Our aim is to reestablish these microbes in mine soils and determine their impact on forest community development.Read moreRead less
Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This pr ....Environmental fingerprints of biogeochemical cycles embedded in tree rings: Linking global climate change to local long-term forest productivity. Forests cover one-third of the Earth's land surface and account for 80-90% of plant carbon and 30-40% of soil carbon. Forest carbon stocks and dynamics respond to and interact with global climate change (GCC). Recent tree ring research highlights the worsening impact of GCC and acid deposition on long-term forest productivity in central Europe. This project seeks to develop and apply novel tree ring technologies for linking biogeochemical cycles of carbon and nutrients to long-term forest productivity in different regions, and to provide a scientific basis for accounting for long-term forest productivity and carbon stocks in response to future GCC.Read moreRead less
Is reintroduction of soil foraging animals critical for the restoration of degraded semi-arid woodlands? Locally-extinct animals are important, not only for their intrinsic value, but because they are thought to be essential for maintaining and restoring healthy ecosystems. This project will give us valuable insights into how ecosystems may have functioned prior to the loss of native animals, and how ecosystems can be restored when the animals are reintroduced. Our research will provide Australi ....Is reintroduction of soil foraging animals critical for the restoration of degraded semi-arid woodlands? Locally-extinct animals are important, not only for their intrinsic value, but because they are thought to be essential for maintaining and restoring healthy ecosystems. This project will give us valuable insights into how ecosystems may have functioned prior to the loss of native animals, and how ecosystems can be restored when the animals are reintroduced. Our research will provide Australian Wildlife Conservancy with the knowledge they need to continue their reintroductions, and information that encourages land managers to adopt strategies to ensure the survival of reintroduced animals outside of formal reserves.
