The challenge

A snapshot can’t show a trend.

Visual inspections, sonic tomography, and resistance drilling reveal a tree’s condition at a point in time. They don’t show how its structural response changes as decay spreads or reaction wood develops.

Continuous monitoring adds the missing time dimension: evidence of whether a tree’s response is changing, between assessments.

The solution

Continuous visibility.
Meaningful signals.

A compact sensor at the root flare uses aerospace-grade motion sensing to track movement relative to the tree’s normal resting state. Local weather data puts every movement in context.

Observed root-plate tilt plotted against wind speed with a structural response curve
Root-plate tilt × wind speed: the tree’s structural response.

Ultra-precise sensing

Detect 0.01° of trunk lean—about a business card beneath a six-foot level.

Always-on monitoring

Track movement and changes in resting lean continuously, not just during a site visit.

Weather calibration

Automatically relate tree movement to local weather and measured wind speed.

Smart alerts

Receive an alert when tilt for a measured wind speed exceeds expectations for a healthy tree of that size and species.

Data-backed decisions

Your trees.
Your thresholds.
Your judgement.

Follow trends, capture weather events, and build a documented record of how each tree changes. Adjust default alert thresholds per tree for client risk tolerance and site-specific factors.

Use the signals to inform your recommendations for pruning, cabling, removal, or continued monitoring. Telemetree supports your professional assessment—it doesn’t replace it or guarantee safety.

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.

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.

How Telemetree works

From installation
to insight.

Compact Telemetree weather-proof monitoring sensor

About the size of a computer mouse.

  1. 1

    Identify qualified trees

    Choose high-value, historic, or heritage trees, or trees whose location carries a risk to safety or property. Residential properties, commercial campuses, parks and arboretums, transportation and utility corridors, and government facilities are all potential settings.

  2. 2

    Install & activate · about 20 minutes

    Your existing crew affixes the weather-proof device at the root flare using common tools. Enter sensor orientation, trunk diameter, sensor height, species, and age group in the activation app. The device transmits data wirelessly to the Internet.

  3. 3

    Monitor & report

    Access real-time data, alerts, trends, and weather-event records. Generate periodic assessment reports and share your data-backed recommendations with customers.

  4. 4

    Designed for minimal maintenance

    The device and battery require no maintenance and are designed to last 2+ years. If a device is damaged or removed, an alert is sent.

FOR YOUR ARBORIST BUSINESS

Stability-as-a-Service.

A differentiated offer for your high-value residential, commercial, and government accounts—and a new recurring revenue line for your practice.

Recurring revenue

Each installed device creates an opportunity for ongoing income with minimal additional labor.

Your crew can install it

Use existing crew members, common tools, and a simple activation app.

A documented record

Support your recommendations with evidence of how each tree changed—and build customer trust.

A differentiated service

Offer ongoing stability monitoring alongside your existing assessments and tree care.

Faster client reports

Automated reports replace hours of paperwork with a 15-minute review and sign-off.

More proactive care

Earlier identification of compromised trees helps you schedule work rather than react to emergencies.
