Arboriculture guide: dangerous trees, rigging, and working at height
A client-friendly guide to dangerous tree indicators, when to remove a tree, working-at-height hierarchy, and tree rigging basics.
When to remove
Removal is considered when defects, targets, species condition, access, and practical mitigation options make retention unreasonable.
Working at height hierarchy
Work should be planned to avoid height exposure where possible, use safer access methods when needed, and reserve climbing or complex rigging for suitable situations.
Tree rigging
Rigging controls how limbs and stems move when they cannot be safely dropped. It depends on anchor points, load paths, friction, landing zones, and communication.
