As a co-founder and former President of WRA Inc., Mike formed the company to incorporate the best scientific information on the environment to assist clients with environmental compliance and to assure successful implementation of habitat protection and restoration actions. Mike’s work has focused on environmental permitting and habitat restoration, large scale conservation planning, and expert testimony.

Mike has consulted internationally on wetland ecology and restoration. He has authored or edited several books and more than 50 articles on wetland ecology and mitigation published in national and international scientific journals. He was a Professor of Biology at San Francisco State University for 22 years and was the Director of the University’s Romberg Tiburon Center for Environmental Studies. He was trained as a US aquanaut in the NOAA “Man-in-the Sea” program and participated in five underwater missions.

Mike has successfully completed major wetland mitigation and restoration projects for transportation agencies, port authorities, utilities, private developers, and non-profit organizations. He has been the lead biologist for major conservation plans at Tejon Ranch in Kern County, for the Sunrise Powerlink in San Diego, and for several large scale wetland restoration projects throughout the nation. He has received awards for his work at the 1000-acre Bolsa Chica tidal restoration project (Bolsa Chica Conservancy Conservator of the Year, 2000), the Gateway Center tidal wetland on San Francisco Bay, and for the design of freshwater wetlands at the Santa Lucia Preserve in Monterey.

As a recognized expert in his field, Mike has served on national advisory committees to the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Administration, and the National Wetlands Technical Council in the development of federal wetland policy and research. He has served as a peer reviewer for State TMDL programs, serves on the Wetland Recovery Program’s Science Advisory Panel, and is a member of the City of San Francisco Wastewater Treatment Technical Advisory Team. Mike has participated in scientific advisory missions to the Philippines, Japan, and China. He has also provided expert witness services to the Department of Justice, the State of California, and many private parties.

Mike is a Professor Emeritus at San Francisco State University. He has taught courses in wetland restoration and mitigation for the U.S. Army Corps of Engineers, the Wetland Training Institute, and CLE International. He also teaches the 40-hour Wetland Delineator Certification course.

Mike serves on a number of expert panels and provides peer review consultation. He is a member of the South San Francisco Bay Salt Pond Restoration Project Science Advisory Team, the southern California Wetland Recovery Plan Science Advisory Panel, the Ballona Wetlands Science Advisory Panel, the City of San Francisco Wastewater Master Plan Technical Advisory Committee, and the Boeing Santa Susanna Laboratory Expert Stormwater Panel. He is also a peer reviewer for TMDL’s proposed by various State Regional Water Quality Control Boards including the Lake Elsinore nitrogen TMDL and the Guadalupe River Hg TMDL.

Mike has provided expert consultation and witness services for litigation involving land valuation, wetland delineation, and wetland restoration. He has testified for both defendants and plaintiffs and his clients have included the US Department of Justice, the California State Attorney General’s office, and private parties. He has been accepted as a qualified witness in federal and state courts. Additional information is available on the cases he has testified in through request.

Mike was elected in 1984 as a lifetime Fellow of the California Academy of Sciences.
