SelecTree Tree Selection (A tree selection guide) is an interactive program designed to match trees with planting sites. Selectree will search a database of 1,156 trees with (ultimately) over 60 tree and site characteristics. Selectree is sponsored by CDF CDFFP (California Department of Forestry and Fire Protection) and UFEI UFEI (Urban Forest Ecosystems Institute.) At this time Selectree is intended for use in California only.
