Unlike banks, there are no trees that are too big to fail. Some failures are tragic and spectacular, others cause no harm. Assessing the likelihood of failure and risk is always a good idea, especially when large trees and valuable targets are involved. The Monterey cypress (Cupressus macrocarpa) pictured here fell over because its roots were repeatedly damaged by mowing the lawn underneath it, the soils the roots were growing in was shallow and weakly structured, the tree had been excessively and poorly pruned and was top heavy, high winds were constantly hammering the tree, and trees in the vicinity had been removed. I am offering a tree risk assessment package to help clients identify and manage potential risks posed by trees.
