Beginning in 2001, the annual reports include non Federal Aid research as well as Federal Aid. Beginning in 2014 the annual report was issued with executive summaries for each project. For those projects receiving Federal Aid funding, the full Federal Aid report is included in the print binder and cataloged by project title in the Library catalog. Progress reports for mammals and avian Federal Aid research. See Mammals Research: Progress Reports (1939-current) for a listing of collated reports for each mammals project (avian to be added in the future).Continues: Wildlife Research Reports.
