SMART FOREST – ACOUSTIC MONITORING OF FOREST AREAS
A Forest Can Change Before Anyone Knows
Illustrative sequence: one access road, five moments. By the next patrol, the landscape has changed.
- Full forest
2. First clearing
3. Loss spreads
4. Major clearing
5. Extensive loss
A sound breaks the pattern.
A tree-mounted sensor flags a possible cutting sound.
Nearby sensors hearing the same sound help narrow down its source.
A sensor listens from the tree
A tree-mounted sensor listens for sounds that need attention.
- Listen continuously between patrols.
- Flag chainsaw and impact sound patterns.
- Send a candidate event for review.
Inside the forest sensor.
Microphone, radio and battery in one sealed unit, strapped to a tree.
- Acoustic sensing flags sounds that need review.
- Battery supports autonomous field operation.
- Sends short alerts over LoRaWAN — no mobile coverage needed at the tree.
Map the monitored zone.
Turn a suspicious sound into a located, reviewable alert.
- Compare nearby sensor signals to corroborate the event and flag possible false alarms.
- Review the sensor location, time, sound type and confidence.
- Forward the alert and supporting details to the responsible ranger.
