(415) 338-3703

Dr. Michael Vasey is a passionate believer in the need for good science to inform management decisions and public engagement in the cause of conserving the San Francisco Estuary (SFE). He left a career in teaching conservation biology at San Francisco State to practice conservation biology as manager of the SF Bay NERR. Mike earned his Ph.D. in Environmental Studies from UC Santa Cruz and, before that, an MA in Ecology and Systematic Biology from San Francisco State. He co-led a research team assessing tidal wetland vegetation in the SFE and brings this ecological expertise to his work as the SF Bay NERR manager. For over ten years, Mike was the lead in a collaborative process to design the SF Bay NERR and this resulted in its successful designation in 2003. He returned as Interim Director in June 2013 and later was hired to the permanent Director position in March 2015 after a national search. Dr. Vasey has actively worked to build good relations with staff and core partners, and also to position the SF Bay NERR to make an important contribution to regional science and management in the SFE. In his spare time, Mike pursues an avid interest in manzanita systematics and the impacts of summer fog on coastal chaparral.
