In cases where assisted colonisation is the appropriate conservation tool, the selection of recipient sites is a major challenge. Here, we propose a framework for site selection that can be applied to the Australian biota, where planning for assisted colonisation is in its infancy. Characteristics that will be important drivers in the decision-making process include the size of a recipient site, the potential to augment corridors and respond to niche gaps, the maximisation of climatic buffering, bioregional similarity, tenure security, and the minimisation of opportunities for hybridisation and invasiveness. Sites we suggest be precluded from assisted colonisation include sites of high species endemism, IUCN category 1 reference reserves and fully-functioning threatened ecological communities.

Northern Australia's globally significant savannas and rivers face major threats, from cattle to weeds to land clearing to climate change. In the face of imperatives and pressures such as reducing carbon emissions, nature conservation, alleviating Indigenous disadvantage, the resources boom and global food security, how should development be managed to protect its globally significant ecosystems? Nine planks in a ‘Sustainable Northern Australia’ agenda are proposed: (i) enhance investment in mitigating pervasive landscape threats; (ii) strengthen support for Indigenous Caring for Country activities and incorporation of Traditional Ecological Knowledge into land management; (iii) align and strengthen invasive species control and management; (iv) facilitate new economic development pathways focused on sustainability; (v) build climate resilience by maintaining and enhancing landscape-scale connectivity; (vi) protect free-flowing rivers from dams and major water resource development; (vii) establish and effectively manage a large interconnected network of protected areas; (viii) develop cooperative governance arrangements; and (ix) enhance knowledge generation and research and monitoring capacity.
