Ike left a mess all across East Texas in his wake, and the extensive tree damage will take awhile to completely clear up. Many trees will retain scars for their rest of the life, though those scars will eventually be hidden. I’m referring to broken branches not properly pruned, or stripped bark, leading to internal decay and hollow trunks and weakend branches. This is why a careful evaluation of the trees on your property is important.
Leaning trees are potential hazards, and need to be carefully evaluated. If roots have been broken, then the tree has little chance of a good, robust recovery. Mature trees that have been partially uprooted, or, with major crown damage, are candidates for removal since full recovery is unlikely and future problems are probable.
I found some very good information out of the University of Florida Extension service on hurricanes and trees. They ought to know, since they have dealt with many devestating hurricanes in the last several years. The Texas Forest Service also has some useful information storm-damaged trees. These links, and a link to an article I wrote on trees and storm damage can be found at: http://easttexasgardening.tamu.edu/treesandstormdamage.html
There is also a link on finding a certified arborist. The International Society of Arboriculture (ISA) is one of the leading tree care (arboriculture) industry’s associations, and it sponsors a rigorous certification program for its members. Certified arborists have passed a comprehensive examination showing competency and understanding of tree biology, management and related issues. You can learn more about the ISA and find members on their web site Trees Are Good.
