Most Recent Update: 5 July 2006.
(1) This is the archived version of the 1966 - 2005 analysis. Remember the disclaimer! The interactive programs on the website are no longer supported, and may not be fully operational.
(2) There are probably a few species naming issues that lead to empty result pages.
(3) Maps (e.g., distribution maps) have not yet been updated with 2005 data. Older versions are still available, so please note the time periods covered by each set of maps.
(4) Some species are grouped for analysis. These are indicated on the selection lists.
(5) Data for annual index graphs are now listed below the graphics in the regional and species-specific trend results.
(6) Credibility codes for trend estimates updated on 6/03/2005 in response to user comments.
(7) Earlier versions of the web site have been archived, and are accessible via links.
(8) Trend results are now highlighted to indicate significant population declines or increases.
(9) (Caution added 1-17-2007) Some of the route-level results are currently unavailable due to security concerns.
Summary information on population change by region and time period
This program allows you to display trends for 3 time intervals, by species. Indices are provided as links from the species names
