Project: This project was initiated to document the tree species (including shrubs with tree-like forms) in Old East Davis (OED). The trees inventoried included street trees, front yard trees (and a few backyard trees), and commercial property trees. Additional information was obtained from the City of Davis Landmark Trees list and the Street Tree maps. This list will be updated as needed. Sixty-one species or genera of trees were documented in OED. Errors in this document are the responsibility of the author.
Location: This list of trees is specific to OED. The boundary of OED is: L Street on the east; 2nd Street railroad tracks on the south; I Street railroad tracks on the west, and Yale Drive on the north.
