Gavin Archbald is a senior restoration ecologist and project manager with H. T. Harvey & Associates, specializing in the management of restoration projects in wetland and riparian communities. He has nearly a decade   of experience working in tidal marsh, freshwater wetland, riparian, coastal scrub, marsh-upland ecotone, and oak woodland communities. He is skilled in delineating wetland and riparian habitats and is certified in applying the California Rapid Assessment Method (CRAM) in tidal marshes, depression wetlands, and riparian areas. Gavin has extensive experience mapping and monitoring a range of vegetation communities, including through the use of remote sensing technology.

At H. T. Harvey & Associates, Gavin creates cost-effective, feasible restoration designs that provide multiple benefits. He contributes to all restoration project phases from planning and regulatory permitting, to design and construction, to long-term monitoring and permit compliance reporting.

Examples of his project roles include:  

  • Managing all maintenance, monitoring, and reporting, as well as coordinating subcontractors, for a 10-acre riparian and wetland mitigation site owned by BART in Fremont, California.
  • Provides planning, permitting and construction support for 20 new high tide refuge islands for the California Coastal Conservancy to be constructed in 2020-21; leads monitoring of previously constructed high tide refuge islands.. Read the report of the first project phases here and a project poster here.  
  • Screening soils for contaminants and suitability, including by writing the QA plan for soils imported to the South Bay Salt Pond Restoration Project, and by assessing soils for Phytophthora and invasive plant risks before they were used to remediate scrub and historical forests in San Francisco.
  • Evaluating the health of tidally influenced streams in Santa Clara County using the California Rapid Assessment Method (CRAM).
  • Analyzing soils, hydrology, and invasive plants and writing a mitigation and monitoring plan to enhance native riparian oak woodland through weed control, plantings, and cattle exclusion in Dublin, in Alameda County, California..

Gavin earned an M.S. and B.S. in Biology from San Francisco State University and a B.A. in Communications from the University of California, San Diego.
