Document Summary
Prediction of species loss based on current activities. Habitat destruction is the major cause of species extinctions. The destruction of habitats drives the loss of species. However, predictions from theory do not match observations. We don"t see as many extinctions as predicted in theory. Such habitat destructions are predicted to cause time-delayed extinctions. We only have a small proportion of documented species extinctions to compare this with, and there are even rediscoveries of such extinct species. This is because extinction requires the animal not to be seen for 50 years. Need to look at whole picture in order to determine the effect on species. So, be ready to explain major threats to australian biodiversity. Biodiversity offset: aims to minimise loss in biodiversity from development. Predict damage to see if there is no-net loss. Land in kingsgrove was removed for m5 expansion. We needed to find the same thing of equal value nearby to conserve the effect.
