For most native wildlife, it is not known how their population will respond to climate change and land use change, making it challenging to manage these species for future conditions. Modelling can be used to help predict the viability of species under different scenarios. Focused on the Greater Glider, this research set out to link biophysical models with models of landscape dynamics and population dynamics to improve our understanding of future changes in species populations. Our results predicted significant declines in greater glider populations over a 50-year period and when considering biophysical processes, our modelling framework suggested additional population declines.
