RESEARCH

Tim Bargar moved joined the USGS in 2008 and has worked to build research collaborations with federal partners to evaluate contaminant impacts on the nation’s trust resources. He has developed working partnerships with biologists at the Everglades, Biscayne Bay, and Virgin Islands National Parks to better understand the potential impacts from existing and potential future contamination. Owing to his previous employment with the USFWS, he has continued his work with the National Key Deer Refuge to evaluate the impacts of mosquito control operations on species that are candidates for listing under the Endangered Species Act.

BACKGROUND

His dissertation investigated a potential non-lethal, non-invasive method for assessing oviparous organism exposure to persistent organic contaminants. Prior to joining the  U.S. Geological Survey, Dr. Bargar worked with the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency, and the U.S. Fish and Wildlife Service. While with NOAA, he participated in the investigation of pesticide impacts in the Everglades National Park while completing his PhD. He moved on to the Office of Pesticide Programs of the USEPA where his responsibility was the conduct of pesticide ecological risk assessments within the Federal Insecticide, Fungicide, and Rodenticide Act process. He then joined the South Florida Ecological Services Office of the USFWS in 2003 and participated in activities related to the Comprehensive Everglades Restoration Plan (CERP). His responsibilities primarily involved the assessment, and associated ecological risks to federally listed species, of contamination on properties acquired for incorporation within the CERP. Additional responsibilities included evaluation of pesticide risk to federally listed species as a result of pesticide use on national wildlife refuges.
