A comprehensive evaluation of elemental contamination was done on the Alamose/Monte Vista national Wildlife Refuge, San Luis Valley, Colorado,during 1989-90. Water, sediment, mallards, mallard eggs, American coots,and mallard food items were collected for elemental analyses. In addition, adult mallards were collected during winter and 20 different tissues were removed for histological analysis and diagnosis of avian cholera. Copper and zinc from several sources exceeded aquatic life standards for the Rio Grande River Basin. Acute toxicity tests using Ceriodaphnia dubia as the test organism were performed on water samples during both years. In 1989, mortality of the test organisms for all samples was less than 20%. In 1990, a sample from well #7 resulted in 44% mortality and a sample from well #5 resulted in 33% mortality.Chemical characteristics of all water samples were within normal ranges for wetlands during both years.

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) Whitefaced 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).
