What is WUCOLS?

Water Use Classifications of Landscape Species (WUCOLS) provides a guide to estimating irrigation water needs of landscape plantings in each of 6 distinct California climate regions. WUCOLS was developed by the University of California Cooperative Extension in cooperation with landscape professionals and funded by the California Department of Water Resources.
This app provides the WUCOLS III version of the list, which is not the current version. The WUCOLS IV version will be forthcoming.
