Ron Duke is a wildlife and wetlands ecologist who has directed thousands of projects since he started with the firm more than 30 years ago. President of H. T. Harvey & Associates since 1990, he guides its overall technical and philosophical direction as a premier ecological consulting firm. He is an expert on the endangered salt marsh harvest mouse and the ecology and restoration of the marsh habitat on which it depends.

While Ron’s work has covered most aspects of the firm’s services, over the last decade he has focused his project work mainly on marsh restoration and ecology projects. These have included the following efforts:

  • South Bay Salt Pond Restoration Project —the largest (~15,000 acres) restoration project of its kind in the western United States
  • Bair Island Restoration Plan—  more than 1000 acres of tidal marsh restoration
  • Elkhorn Slough Restoration Plan—a major project to raise the elevation of dying marshes
  • SAFER Bay Shoreline Levee, Menlo Park to Mountain View—a 10-mile-long levee to prevent coastal flooding and protect from sea-level rise
  • San Francisco Bay Invasive Spartina Control Biological Assessment and Refuge Island Plans—creation of high-tide refuge for Ridgway’s rails as invasive Spartina is removed
  • Humboldt Bay Invasive Spartina Management Plan—a program to eliminate invasive Spartina from the entire bay and the Eel River
  • Jose Permit Assistance Program, South Bay Marshes—a 23-year study to characterize the effects of effluent discharge on the marshes of the south San Francisco Bay

Ron received an M.A. in animal ecology from the University of Colorado, Boulder, and a B.A. in biological sciences/ecology from the University of California, Berkeley.
