(1) This is the first release of the 1966 - 2002 BCR analysis, and we ask for public comments. Because this analysis is a new product, we suggest that you carefully review results before use, and report possible problems to us.
(2) There are probably a few species naming issues that lead to empty result pages. Please bring these to our attention, and we will correct them.
(3) Trend results from earlier analyses have been moved to archives, and we provide a link to the standard regional analyses.
(4) Some species are grouped for analysis. These are indicated on the selection lists.
