Below are two Phase I Avian Risk Assessments reports, prepared by Paul Kerlinger, for Vermont's East Haven Wind Farm (July 2003) and New Hampshire's Lempster Mountain Wind Power Project (June 2005). Phase I assessments have proven inadequate in assessing mortality at several sites in the U.S. including Mountaineer in West Virginia and Meyersdale in Pennsylvania. The US Fish and Wildlife Interim Wind/Wildlife Guidelines calls for multi-year evaluation of avian and bat activity using remote sensing.

Starting with our first interagency meeting on April 8, 2005, we have generally discussed three broad categories of activities that pose a potential concern for fish and wildlife resources. These include the potential for bird and bat collisions with turbines, habitat fragmentation effects on wildlife and impacts to waters/wetlands. At the April 8, 2005 interagency meeting, we recommended that CEI collect three (3) years of radar data on spring and fall bird/bat migrations to document the spatial and temporal use of the airspace by these flying vertebrates. Three years of radar data should be sufficient to gather information on the spatial and temporal distribution of birds in the airspace, including the year-to-year variability in migration patterns at this site, and represent our normal request for these data at wind projects. We have consistently requested that this data be collected at our meetings and field visits and continue to make this request for radar information.
