Vegetation Encroachment Is a Data Problem, Not Just a Maintenance One

Vegetation management programs are usually built around a maintenance cadence: clear the corridor, move to the next section, come back on schedule. That structure works until growth rates vary across a network, which they always do, and the schedule quietly stops matching reality.

The Corridor Doesn't Grow on a Calendar

Rainfall, soil type, and species mix mean some spans need attention long before their scheduled clearing date, while others could safely wait. A fixed-interval program either over-services the slow-growing spans or under-services the fast ones. The second failure mode is the one that produces an outage.

Where Aerial Survey Changes the Calculation

A structured aerial corridor survey turns vegetation management from a scheduling exercise into a measurement exercise. Instead of assuming every span needs the same attention on the same interval, the survey tells you which spans are actually approaching clearance limits, so crews get sent to where the risk is, not where the calendar says to look.

This is the same discipline we apply to inspection and stringing work: the aircraft's job is to produce a reliable answer to a specific operational question, not just to fly over the corridor and generate footage.
