Lorenz, A.A., and Byrd, K.B., 2018, Habitat Structure Maps for the Central Valley of California 2013-2017: U.S. Geological Survey data release,


We produced a time series of maps of habitat structure within wetlands of the Central Valley of California. The structure of open water and tall emergent vegetation, such as Typha spp. and Schoenoplectus spp., is critical for migratory birds. Through field observation and digitization of high resolution imagery we identified the locations of tall emergent vegetation, water, and other land cover. Using a random forest classification, we classified multispectral Landsat 8 imagery 2013-2017. We used images from the fall when most wetlands are flooded and the summer to separate trees and tall emergent vegetation. The final maps show the distribution and extent of tall emergent vegetation within wetlands. Final time series has two products: [...]

The data were created to quantify habitat change within wetlands in Central Valley of California specifically to quantify tall emergent vegetation extent and distribution in the fall, at the time of wetland flood up and beginning of the migratory bird season.
