Utility Vegetation Management Program Administration and Planning

This domain tests whether you can run a utility vegetation management (UVM) program as a documented, risk-based system rather than a series of tree jobs. The exam emphasizes planning, prioritization, records, and the link between vegetation and reliability.

Core rules and concepts

  • A written UVM plan should define scope, objectives, clearances, cycle lengths, species strategy, notification, environmental compliance, and emergency response.
  • Maintain an inventory: circuit or line voltage, spans, species, compatibility, access, landowner, and hazard ratings in GIS or a work-management system.
  • Prioritize by risk, not miles alone: likelihood of contact or outage multiplied by consequence (critical customers, public safety, fire, regulatory exposure).
  • Use a work cycle for routine maintenance, plus hot-spot and emergency work; track backlog, completed units, and rework.
  • Document inspections, prescriptions, permissions, and completion; use KPIs such as trees per crew-day, clearance compliance, outage reduction, and cost per mile.

Worked example

A 12.47 kV feeder has had three vegetation outages in two years, 40% incompatible species, and a school crossing. A high consequence score and high likelihood move it ahead of a longer rural circuit with few customers. The plan schedules inspection, landowner notices, directional pruning, removals, and follow-up in one work package.

Traps that cost marks

Treating cycle length as a clearance standard; measuring success only by trees trimmed; ignoring outage history; failing to document landowner contact; and assuming all circuits deserve equal priority.
