Hydro line operations are a major maintenance practice in all municipalities that can have a large affect on its urban forests. Trees conduct electricity and therefore trees planted under or next to power lines must be regularly pruned or removed to ensure public safety and maintain hydro supply. When tree branches grow into or come in contact with hydro wires, they can cause fires, power outages and can become safety hazards. Some jurisdictions have responded by executing long term plans that involve such practices as site-specific plantings i.e. species that will not reach a height that will interfere, pruning or removing trees to maintain clearance and prevent unsafe conditions.
