SelecTree - SelecTree is an interactive tree selection website developed by the Urban Forest Ecosystems Institute at Cal Poly. The goal is to help select the right tree species for a specific site. Users can select for native trees, trees fit for growing under powerlines, trees that attract bees and other wildlife, flowers or leaves of a specific color, disease resistance and many other traits. This is truly one of our favorite sites for information on trees--don't miss this one!
iTree Suite - iTree is a state-of-the-art, peer-reviewed software suite from the U.S. Forest Service that allows communities of all sizes to strengthen their urban forest management and advocacy efforts by quantifying the environmental services that trees provide and assessing the structure of the urban forest. The environmental benefit data presented in the San Diego County Tree Map comes directly from iTree Streets.
