Species Conservation Assessments - Birds

The Region 2 Species Conservation Program species assessment reports for the majority of the sensitive species and management indicator species for the region. More than 200 reports for plants and animals are posted on this Web site.

Note: You will need Acrobat Reader to view the below PDF documents. If you do not have Adobe Acrobat Reader, please click the above link to download and install this free program.

Recommended citation for Region 2 assessments can be found on page 2 of each assessment. For a complete alphabetical bibliography of assessments published by the R2 Species Conservation Program, click here!

Errata may have been posted with individual Assessments, to document subsequent corrections or clarifications.

We have also been doing a pilot test of Addenda, as a method to maintain the currency of information in the assessments. Fifteen examples of these addenda have been posted as well, underneath the relevant Species Assessment. We would appreciate hearing your feeback about the value of the Addenda, to help us decide whether to pursue this approach. Please e-mail Peter McDonald (peter.mcdonald@usda.gov) your feedback.
