Ellen Tatum Pimentel is a senior plant ecologist at H. T. Harvey & Associates, with nearly 15 years of experience. She plans, implements, and monitors a variety of projects in vernal pool, grassland, riparian, freshwater and tidal wetland, and coastal dune communities throughout California. Ellen has led or conducted vernal pool branchiopod and amphibian surveys, vegetation classification and mapping, invasive plant mapping and control, botanical surveys, and vegetation and wetland monitoring and ecological assessments. She also is adept at preparing annual summary reports and technical analyses in support of federal Endangered Species Act Section 7 and Section 10 compliance permits, biological resources content of CEQA and NEPA compliance documents, wetland delineation reports, and biological constraints analyses. Ellen is trained in wetland delineation and the California Rapid Assessment Method (CRAM) for riverine, depressional, estuarine, and vernal pool wetlands, as well as in Clean Water Act (Section 404), CEQA, and other regulatory permitting requirements. She holds federal and California permits to conduct surveys for listed vernal pool crustaceans and amphibians, and a collecting permit for state listed plants.

Examples of her project roles include:  

  • Serves as project coordinator and plant ecologist for the Los Vaqueros Reservoir watershed project in Contra Costa County, California. Ellen oversees the implementation of conservation measures for special-status species, including the California red-legged frog, California tiger salamander, western pond turtle, and San Joaquin kit fox. She conducts surveys for vernal pool branchiopods and rare plants and monitors restoration areas on the watershed and conservation properties. Ellen also prepares and reviews technical memorandums and annual reports required for compliance with the project’s federal and state permits.
  • Coauthor of a habitat conservation plan (HCP) for the Feather River region on behalf of the California Department of Water Resources. The HCP covers numerous species that may be affected by management of this large, complex river system, including the giant garter snake, Swainson’s hawk, bank swallow, tricolored blackbird, valley elderberry longhorn beetle, vernal pool fairy shrimp, and vernal pool tadpole shrimp.
  • Led surveys for special-status species associated with vernal pools, including plants, branchiopods, and amphibians in Sacramento, Placer, and Yuba Counties and within California’s Bay Delta Conservation Plan area.

Ellen received a M.A. in Biology and a B.S. in Environmental Science from Humboldt State University.
