How trees become hazardous
There are many reasons why your tree may pose a threat to you and others. Trees become a hazard for many reasons. One of them is when they begin to lean. This is a problem obviously because a collapse is possible. Once the roots are showing, and there is cracked soil around the perimeter’s base, there is a definite hazard for those around this tree. A tree with cavities also poses a hazard. This weakens the tree and could lead to it’s death.
If a tree has more than 1 trunk, it’s very capable of breaking if the trunks aren’t firmly attached. Trunks that are large with splits and/or crack are more likely to fail. Branches that are weakly attached become a problem immediately thereafter. Look for V-shaped forks branches. They’re more delicate than U-shaped ones. Any branch that’s a “hanger” should be removed immediately.
These create a great hazard to anyone immediately underneath one. Deadwood is another hazardous situation where eventually a branch or limb will collapse and fall. This situation calls for fast attention. The branches should be removed for the safety reasons before property or physical damage occurs. Trees do not need to be a hazard with effective pruning and preventative maintenance.
