Assisted colonisation (also known as assisted migration and managed relocation) has the potential to be an incredibly useful, but contentious, management strategy to combat climate change. Defined as the “intentional movement and release of an organism outside its indigenous range to avoid extinction of populations of the focal species” (IUCN/SSC 2013), it is part of the new conservation introduction toolkit. The IUCN guidelines for reintroductions and other conservation translocations describe issues for assessing the feasibility, planning and implementation of assisted colonisation. These issues are to be tackled using clear, transparent, and explicit decision-making frameworks. We will present an overview of the field of decision-making, and show how relevant it is to assisted colonisation under climate change. The structured decision-making approach highlights the need for us to think more about our values, uncover more information about the economic and social costs of different outcomes from an assisted colonisation (e.g. extinction, species becoming pests, novel ecosystems), and evaluate the different kinds of success following assisted colonisation trials.

Species on the Move

An International Conference Series

The conference brings together scientists and natural resource managers working in the disciplines of global change, biogeography and evolution, and relevant in contexts of natural resource management, biodiversity management and conservation, and theoretical ecology.


Species responses to climate change is a rapidly evolving research field, however, much of our progress is being made in independent research areas: e.g. understanding the process vs responding to the implications, terrestrial vs marine ecosystems, global meta-analyses vs in depth species-specific approaches. This interdisciplinary conference develops connections between these parallel streams, and across temporal and spatial scales.
