A tree hazard, also known as a hazardous tree, refers to a tree that poses a potential risk to people or property due to its condition, location, or structural integrity. Identifying features can help determine whether a tree is hazardous or not. Here are some key features to look out for when assessing tree hazards:

1. Leaning or Unbalanced Growth: A tree that leans significantly to one side or shows signs of unbalanced growth may indicate root problems or structural instability, making it prone to falling.
2. Cracks or Cavities: Visible cracks or cavities in the trunk, branches, or main stem can weaken the tree's structure, making it vulnerable to breakage or collapse.
3. Dead or Dying Branches: Dead branches or those with no foliage are known as "widowmakers" and can fall unexpectedly, posing a serious danger. These branches can be identified by their lack of leaves, brittle appearance, or bark that easily detaches.
4. Decay or Fungus Growth: Presence of fungal growth, conks, or mushrooms around the trunk or base of the tree often indicates internal decay. Decay weakens the tree, making it more susceptible to failure.
5. Root Problems: Visible signs of root damage, such as heaving soil around the base of the tree, exposed roots, or severed roots due to construction or erosion, can compromise the tree's stability.
6. Multiple Trunks or Codominant Stems: Trees with two or more trunks that grow closely together and share the same attachment point can be structurally weak. The connection between these trunks is often prone to splitting.
7. Proximity to Structures or Utility Lines: Trees that grow too close to buildings, power lines, or other structures can pose a hazard if they fall or drop branches.
8. Previous Damage: Trees that have been previously damaged by storms, lightning strikes, or improper pruning may have weakened structures that increase the risk of failure.

It's important to note that assessing tree hazards can be complex, and it's recommended to consult with a professional arborist or tree expert for accurate evaluations and appropriate action.
