In The Nature Conservancy’s California Chapter, Greg provides science guidance and leadership to direct engagements in the state’s Great Central Valley. Current areas of focus include advancing waterbird conservation through compatible agriculture, and restoring riparian and riverine ecosystems through floodplain restoration. His research focuses on evaluating the effects of management actions and advancing understanding of ecosystem dynamics so that conservation actions can be critically evaluated and new restoration strategies can be developed.

Prior to joining the Conservancy, Greg worked as a wildlife biologist studying seabirds for the U.S. Fish and Wildlife Service in Alaska. He has a Ph.D. in Biology and an M.S. in Marine Sciences from the University of California, Santa Cruz and has authored over 30 peer-reviewed publications.  

What Greg is working on now:

I am currently overseeing the monitoring of our fall BirdReturns program which is being implemented to provide habitat for migrating shorebirds on Sacramento Valley rice fields. At the same time, I am revising a journal article that describes the results of first two years of the program. Lastly I am organizing a special session focused on the Sacramento River for the upcoming Riparian Summit conference.
