Study: High Arctic’s biodiversity down 26 percent since 1970

Mammals, birds and fish living in the High Arctic experienced an average 26 percent drop in their populations between 1970 and 2004 due to the loss of sea ice, according to a new report from The Arctic Species Trend Index, “Tracking Trends in Arctic Wildlife .”

The 2010 report, commissioned and coordinated by the Whitehorse, Yukon–based Circumpolar Biodiversity Monitoring Program (CBMP), was presented Wednesday at the State of the Arctic Conference in Miami. It covers 965 populations of 365 species, representing 35 percent of all known vertebrate species found in the Arctic.
