Are All Hollow Trees Hazardous?

Hollow Tree

Some people may look at this stump and conclude right away that it is a hazard.  An arborist may look at this stump and say “not so fast.”  This tree looks scary, but whether or not this tree is a hazard, is based on the amount of solid wood that surrounds the area of decay.

A good rule of thumb is that a tree needs 1-inch or more of sound wood for each 6-inches of stem diameter.  There are other factors involved in determining how hazardous a tree is, but that 1-inch per 6-inches is a good place to start.

An arborist can use a resistograph to help measure the area of decay inside the tree.  If you suspect that you have a hollow tree, before you automatically remove it, talk to your arborist and ask if he can investigate the area of decay. Contact Wood Acres Tree Specialists, certified artborists for a thorough analysis of your trees.

Split Stems in Trees

If you have a tree with co-dominant stems and you see those stems separate like these two are doing, then the tree should be removed as soon as possible.   Cabling systems can be installed in trees with multiple stems to help reduce the risk of this happening, but the cables need to be installed before the stems start to fail. This tree, which is an ailanthus, is a very fast growing species. The faster the growth rate of the tree, the weaker the bonds of the wood are and that increases the risk of failure. Contact Wood Acres Tree Specialists to inspect your trees.

Fungi on Trees

Fungi on trees come in many shapes and sizes. These fruiting bodies indicate that there is some type of fungus living in/within the tree. Some fungi are meaningless, some can be wood destroying organisms. If you see a mushroom growing on your tree, contact Wood Acres Tree Specialists and have us take a look to make sure the tree is okay.
