Landscape design the particular placement of areas devoted to restoration of native vegetation at landscape scales – may facilitate the maintenance of larger populations as well as shifts in species distributions, both of which should help native species adjust to changing climates. However, it is unclear exactly how to design landscapes to best achieve these goals, particularly because future landscapes will involve changed land uses and distributions of native communities which may interact with landscape designs. This supplementary report accompanies the original report by Doerr et al. (2013) (Located at: https://www.nccarf.edu.au/sites/default/files/attached_files_publications/Doerr_2013_Landscapes_biodiversity_climate_change_Summary.pdf) which found that all current landscape design approaches were insufficient for improving the likelihood of persistence for native species (and decreasing the likelihood of persistence for key invasive species) against future climates. For this supplementary report, additional analyses were performed to validate these results using a third case study landscape, the area managed by the WimmeraCatchment Management Authority in Victoria. The Wimmera was selected because it has an overall drier climate, somewhat different vegetation types, smaller total area, and slightly different vegetation types. The supplementary study found that the original conclusions are still valid and that only that the restoration of landscapes to ~30% native vegetation cover improved future landscapes relative to current landscapes.
