To see if it is at risk…
- Tree defects
- Decay development
- Reducing risk
- Limit large low branch removal
- No flush cuts
- Pruning
- Planting properly
- Avoid root damage
- Structural pruning
- Potential causes of risk
- Tree strength and weakness
- Strength of different trees
- Strength of different parts
- Strength reduces with age
- Impairment of uniform stress distribution
- Distribution of loading
- Interruption of growth by living agents
- Inadequate root anchorage
- Damage to existing support
- Direct physical injury
- Cracks from mechanical loading
- Decay
- Risk not related to mechanics
- Remedial Actions
- Move the target
- Remove the defective tree or parts
- Reduce the load on defective part
- Root collar exam and treatment
