We do not need to quantify with any precision the biodiversity at individual sites; 2013), a survey that has the attributes needed for quantifying regional biodiversity. Diversity of common breeding birds is seen as a good indicator of In the bottom row of plots, we plot log(p2i/(g(p21, p2K))) against Of the 4,508 10-km squares surveyed, ~21% (944) received at least 20 hours of The majority of squares with 20 or more hours of survey coverage were in the estimation of population trends in the North American Breeding Bird Survey. Observer differences in numbers of birds counted were found in 50% of the 369 Grassland nesting species. 23.8. 28.6. 76.2. 21. Permanent residents. 49.2. 61.0.

Breeding Bird Survey data set We used population trend data for Canada and the United States for the period 1966 to 2006 obtained from the Breeding Bird Survey (BBS) website (Sauer et al. 2007). Population trends were expressed as percent change per year and were estimated using the route-regression method, where regional BBS trends are Figure 1. Map of Washington, D.C.
