Conservationists ’on the fence’ about barriers to protect wildlife in drylands

ScienceDaily (May 6, 2015)

To fence or not to fence ? That is the question facing conservationists concerned with barriers that keep wildlife in and people out. Researchers say that new policies must be developed before fences are erected — particularly in dryland ecosystems where mobility is essential for both humans and wildlife.

The study’s authors caution that evidence is limited showing that fences are effective management tools, particularly in drylands.

"Large-scale fencing can disrupt migration pathways and reduce access to key areas within drylands, such as seasonal foraging areas," said lead author Sarah Durant of ZSL. "This can lead to severe reductions in migratory wildlife populations and may prompt wider impacts on non-migratory species."

The study says that policies are needed to evaluate whether fences should be erected and should be evaluated based on wildlife movement and distribution, climate change predictions, costs and benefits to local people, and other factors
