Some species face extinction if they are unable to keep pace with climate change. Yet proposals to assist threatened species’ poleward or uphill migration (‘assisted migration’) have caused significant controversy among conservationists, not least because assisted migration seems to threaten some values, even as it protects others. To date, however, analysis of ethical and value questions about assisted migration has largely remained abstract, removed from the ultimately pragmatic decision about whether or not to move a particular species. This paper uses (...) the case study of the whitebark pine, a keystone species of sub-alpine habitats in western North America, to consider how particular cases of assisted migration may be ethically approached. After taking into account the value of species, wildness, place, ecosystems, culture and sentient animals, we conclude that, on balance, there appear to be good reasons to move the whitebark pine.

Our language and metaphors about environmental issues reflect and affect how we perceive and manage them. Discourse on invasive species is dominated by aggressive language of aliens and invasion, which contributes to the use of war-like metaphors to promote combative control. This language has been criticised for undermining scientific objectivity, misleading discourse, and restricting how invasive species are perceived and managed. Calls have been made for alternative metaphors that open up new management possibilities and reconnect with a deeper conservation ethic. (...) Here, we turn to Indigenous perspectives because they are increasingly recognised as offering important and novel voices in invasive species discourse. We examine how Australian Aboriginal elders and land managers (rangers) speak about 'environmental weeds' (the term used to describe invasive plants in Australia) and weed management. Based on qualitative research with five Aboriginal groups in the Kimberley region of Western Australia, our findings indicate that Aboriginal elders speak about weeds through passive, neutral language and prefer metaphors for weed management that focus on health, care and creation. We outline the influence that this language has for how rangers practice weed work and discuss its implications for the mainstream paradigm. (shrink)

Culture, livelihoods and political-economic status all influence people's perception of introduced and invasive species, shaping perspectives on what sort of management of them, if any, is warranted. Indigenous voices and values are under-represented in scholarly discourse about introduced and invasive species. This paper examines the relationship between the Xeni Gwet'in First Nation (one of six Tsilhqot'in communities) and wild or free-roaming horses in British Columbia, Canada. We outline how Xeni Gwet'in people value horses and experience management actions, contextualising the controversy (...) over wild horses amidst power imbalances in the expression of environmental values. We suggest that Indigenous voices are vital to include when evaluating impacts of controversial species and developing management strategies. (shrink)

Ronald Sandler's ‘Climate change and ecosystem management’ provides a fine summary of reasons to modify our approach to ecosystem management given ‘rapid and uncertain ecological change’. We...
