Abstract
Revegetation programs are an important aspect of environmental rehabilitation across Australia. The current paradigm for germplasm selection for revegetation projects is to use locally sourced seed, but this approach may not provide the best outcomes if the local environment has been or will be altered from its "natural" (i.e., historical) state by human activities and/or climate change. We are investigating whether there is adaptive genetic variation in widespread keystone species that could be exploited to maximise survival of foundation species in revegetation projects at sites where environmental conditions have changed/are changing. We are taking an ecological genomics approach, combining genomic scans (DArTseq) and physiological measurements, to assess the degree and nature of genetic adaptation of several widespread eucalypt species across environmental (i.e.,aridity) gradients. Here we present the genomic results we have obtained from Eucalyptus loxophleba ssp. lissophloia (York Gum).
