Meeting Information

California Tree Failure Report Program Annual Meeting - SOLD OUT

* This meeting is sold out!

Date & Time:

Thursday, January 9th, 2014 - 8:30 am - 4:00 pm


The California Tree Failure Report Program (CTFRP) was established in 1987 to collect quantitative information on the mechanical failure of urban trees (trunk breaks, branch breaks, and uprootings). This information is used to develop "failure profiles" for genera and species to more accurately assess failure probability in standing trees and thereby reduce failure potential in urban forests.

Over 200 tree care professionals in California are cooperating in this effort by systematically inspecting fallen trees and reporting failure details for entry into the CTFRP database.
