Abstract

Eucalypt

climate change

The long term success of revegetation efforts will depend upon the planted species' resilience to climate change. Restoration of Australia's degraded and fragmented multi-use landscapes represent multi-million dollar investments, yet current practices take little account of climate change. Until recently there has been a strong focus on using local genetic stock (germplasm) for optimal restoration. In a changing climate this paradigm is being questioned and research on this is urgently needed. Many widespread species occur across a range of climatic conditions and, thus, may possess adaptations that could be utilised to improve climate resilience of restored ecosystems. Species can achieve a widespread distribution via two main mechanisms; (1) by genetically diverging into a series of populations, each specialised for the local conditions, and/or (2) through high phenotypic plasticity (the ability of an individual to adjust its characteristics in response its environment), enabling each individual to thrive in a wide range of conditions. The extent to which each population is specialised or plastic in response to climate will determine the seed-sourcing strategy required for optimal restoration outcomes under a changing climate. In addition, highly specialised populations are likely to be more severely impacted by a changing climate than highly plastic populations, and so the nature of adaptation to climate has implications for the ongoing management of both natural and restored ecosystems.
