Detailed Description

This infographic shows how the density-weighted proportion--or dwp--software package estimates the fraction of carcasses that fall outside the searched area at wind energy facilities. A) Carcass density as a function of distance from the turbine. B) Relative carcass density in the area around the turbine, the total area under the “volcano” equals 1. C) Layout of the area searched. D) The probability of a carcass lying inside the searched area is the volume of the volcano above that area.

Accounting for the fraction of carcasses outside the searched area in the estimation of bird and bat fatalities at wind energy facilities Accounting for the fraction of carcasses outside the searched area in the estimation of bird and bat fatalities at wind energy facilities

Accurate estimation of bird and bat mortality at wind energy facilities requires accounting for carcasses that lie outside the search plots because they lie beyond the search radius or in areas within the search radius that remain unsearched due to sub-optimal search conditions such as thick vegetation, rough or dangerous ground, water, or restricted access to the land. However, carcass...
