Collection Overview: This lidar dataset was collected as part of an NCALM Seed grant for Kyle Hemes at the University of California, Berkeley. This project was designed to understand ecosystem structure as a driver of climatic, habitat, and hydrological services in heterogeneous restored wetlands. The survey area covers Sherman, Twitchell, and Bouldin islands in California for a total of approximately 63 km2Publications associated with this dataset can be found at NCALM's Data Tracking Center
