We have examined trees that have fallen on houses and landscapes and participate in the CA Tree Failure Report Program, a University of CA sponsored program that tracks tree failures, and provides data on these failures, The program sponsors an annual presentation that we attend, where scientific and anecdotal information is exchanged, and tree professionals learn about worldwide work on the problem.
