Tool may save species from climate change
Posted on: Thursday, 28 May 2009, 11:05 CDT
University of Notre Dame scientists have published a paper that describes a program designed to help save various species from the effects of climate change.
The paper, written by Assistant Professors Jessica Hellmann and Jason McLachlan, along with Associate Professor Alejandro Camacho, is aimed at helping policy makers determine when and how to use an environmental strategy known as managed relocation.
Managed relocation, also known as assisted migration,
is a means of preserving species endangered by rapid climate change and other environmental threats, the scientists said. The concept involves moving an entire species potentially hundreds of miles to a place thought to be more accommodating, but which is outside of the species' native range.
The strategy is controversial, since some scientists and policy experts fear such relocations could harm the new habitats, cause extinctions of local species or create further environmental problems, as has been the case with invasive species.
The researchers note the tool does not, by itself, produce management recommendations. They said even within the working group, disagreements still arise over the ethics and efficacy of the managed relocation strategy.
The study that included David Richardson of South Africa's Stellenbosch University is detailed in the Proceedings of the National Academy of Sciences.
