Hazardous Trees: How to Detect Them

Your property landscape won’t be complete without having seeing a tree in it. No matter whether it is small or big, their presence just gives life to the environment. Nevertheless, we may not be aware that trees do also have diseases that need to be eliminated or treated. You wouldn’t wish to have a dying or rotten tree in your right?

It can’t be ignored that sometimes we can’t find out whether our tree is already afflicted with disease or not but through preventive measures we could stop them. You can expect some signs or symptoms so that you can instantly detect the potential problems.

i.    Decay: Inspect trunks and branches for peeling bark, hollow cavities or mushroom and fungi growth on the bark. Presence of these is often a sign of decay, especially if the origin of the growth comes from within the wood instead of the extremity of the bark only. The decision whether or not to preserve the tree depends on your arborists.

ii.    Hangers: They are damaged branches still hooked up in the tree. Whether partially or completely split up from the trunk, hangers may fall suddenly. Hence, they ought to be removed quickly. Make sure you remove the stubs left by the broken or dead branches to avoid the spread of decay.

iii.    Cankers: Cankers usually are due to wounding or disease. These are hollow spots on the branch or stem where the bark is supposed to be. A canker that grows more than half of a tree’s circumference can cause failure even if your exposed wood areas look fine.

iv.    Lean:  Though trees do not automatically have to grow erect, leaning trees may indicate a problem. If you see some exposed roots or cracked soil at the bottom of the tree, this could be an indication that it has started to lean.

v.    Multiple trunks: If a tree has multiple trunk or leaders, chances are it will be less strong than a healthy tree. The form of a trunk or where the union of stem links shows whether a tree is potentially dangerous. Should there be excess or more than two leaders, then you definitely must tie all of them.

vi.    Dead wood: Absolutely nothing much that you can do with a dead tree rather than having it removed immediately. Dead trees and branches are quite unstable and may fall anytime. Dead wood is dry, brittle and easily breaks since it cannot bend once the wind blows like a living tree.

vii.    Weak branch union: That is the area in which the branches aren’t properly or firmly linked to a tree. When branches with similar sizes grow too close with each other, an ingrown bark grows between the branches and inside the union. This bark doesn’t have enough structural strength and the branch unions are also weaker than others that don’t have included barks. The abnormal bark growth can also act as a wedge and result in the branch union to break or split apart.
