Thumbnail of and link to report PDFExecutive Summary

As part of an interagency agreement between the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS), the Alamosa/Monte Vista/Baca National Wildlife Refuge Complex requested help with the synthesis of scientific information for 10 focal species and their habitat requirements in response to common Refuge management activities in the San Luis Valley, Colorado. This information will be instrumental in developing the Service’s Comprehensive Conservation Plan (CCP), which is required by law for each unit of the National Wildlife Refuge System. After consultation with Refuge managers and USGS staff, the 10 species chosen for detailed literature reviews and synthesis of information were the following: (1) American Avocet (Recurvirostra americana); (2) Wilson’s Phalarope (Phalaropus tricolor); (3) Sora (Porzana carolina); (4) White-faced Ibis (Plegadis chihi); (5) Black Tern (Chlidonias niger); (6) Short-eared Owl (Asio flammeus); (7) Brewer’s Sparrow (Spizella breweri); (8) Savannah Sparrow (Passerculus sandwichensis); (9) Northern Leopard Frog [Lithobates (=Rana) pipiens]; and, (10) Tadpole Shrimp (Triops longicaudatus).
