Principal and founder of EcoBridges, formerly cofounder of Ibis Environmental, Anne has been a working biologist since 1982, an environmental consultant since 1986, an environmental consultant in California since 1990, a certified wildlife biologist since 1992, and a business owner since 1995. Her MS in Wildlife Science was received from Utah State University in 1988.

In 34 years, her professional pursuits have included

  • research, inventory, survey, trapping, tagging, writing, recommending, and analyzing
  • endangered birds, mammals, amphibians, fishes, reptiles, invertebrates, and plants, and
  • sensitive and endangered habitats such as wetlands, vernal pools, and riparian systems
    • in compliance with NEPA, CEQA, state/federal endangered species acts, the federal Clean Water Act, and most other relevant local, state, and federal regulations
    • including surveys, impact assessment, environmental compliance, and mitigation development
    • in riparian, desert, coastal, woodland/forest, grassland, lowland, and mountain habitats
    • for biological assessments, EA/ISs, EIR/EISs, Caltrans NESs and NES-MIs
    • in the Sierra foothills, the Modoc Plateau, northeastern California (Modoc and Lassen counties), northern Central Valley, southern Central Valley, the Coast Ranges, San Francisco Bay estuary, and the Gold Country (Sierra foothills)
    • and in Oregon, Utah, Idaho, Montana, Wyoming, Colorado, Florida, New York, Hawaii, and Puerto Rico
    • for pipelines, transmission lines, highways, recreation trails, mine-site reclamation, geothermal development, Air Force airspace actions, wind farms, FERC hydroelectric relicensing, vegetation management programs, and marsh restoration
    • for cities, counties, state agencies, federal agencies, consulting firms, utilities, and nonprofits.

Her primary focus and first love have been identification, biology, and distribution of birds, especially raptors and wetland/riparian species. Much of her experiential background has been in and around freshwater wetlands, wet meadows, salt marshes, riparian zones, and their associated uplands, particularly in northern California and northern Utah.

But her professional experience base is broad and includes, birds, amphibians, reptiles, mammals, invertebrates (VELB, vernal pool branchiopods), and a few plants.
