TelemetreeContinuous root-plate monitoring

Weather tells you what the storm did.
Telemetree tells you what your tree did.

Protect your customers’ most valuable, irreplaceable trees with a continuous record of how their root plates respond to wind—not just a snapshot from the last inspection.

The pull test, reimagined

Every gust becomes a dynamic pull test.

A traditional mechanical pull test takes a specialized crew, a winch anchor, and a load cell to measure root-plate tilt during a single afternoon. Telemetree observes the tree’s response every time the wind blows.

A single sensor at the root flare records root-plate tilt. Paired with wind speed, those measurements form a structural response curve—updated after every windy day.

Root-plate tilt plotted against wind speed, with observed points and a structural response curve
Root-plate tilt × wind speed: the tree’s structural response.

One sensor. At the root flare.

Measure root-plate movement where the tree meets the ground.

Wind supplies the load.

Correlate each tilt response with the wind that caused it.

A baseline that builds over time.

Compare each windy day with the tree’s own historical response.

Unprecedented sensor precision

Small movements. Meaningful measurements.

Subtle root-plate shifts demand extraordinary sensitivity. Telemetree’s sensor noise floor is ten times finer than a premium six-foot level.

Precision comparison using a 72-inch level: paper at 0.003 degrees, business card at 0.010 degrees, three dimes at 0.127 degrees, and pencil at 0.25 degrees. Business card thickness is 0.32 mm.

Data that drives decisions

The storm passes. The record stays.

Every tree develops its own historical baseline. Granular storm-event records capture peak swings and settling, so you can compare a new response with the one you’ve come to expect.

We provide the signals.
You make the final call.

If a tree’s response curve steepens significantly over a 60-day period, Telemetree flags a “significant stability change” and recommends a site visit. It’s a prompt for your professional assessment—not a replacement for it.

Continuous monitoring helps surface long-term structural changes between inspections, giving you a clearer basis for deciding what happens next.

Storm Scout · Area-wide triage

By sunrise, know where to go first.

Track monitored trees and passing storm cells across your clients’ properties. After severe weather, a prioritized triage list helps arborists and urban foresters focus their first visits.

Critical

Severe anomalies, such as a permanent shift in resting lean.

Warning

Gust responses significantly above the tree’s normal baseline.

Check

A sensor may be offline and needs a physical check.
