Listening to Albania's forests, one second at a time
September 28, 20266 min read
At three in the morning, a protected beech forest is anything but silent. Wind moves through the canopy, an owl calls, a stream runs somewhere below. And sometimes — faint, mechanical, out of place — a chainsaw starts. Jehonë exists for that moment.
Why sound comes first
Illegal logging and poaching happen where nobody is watching: at night, in ravines, far from roads and patrol routes. Cameras need light and line of sight. Patrols cannot be everywhere. Sound, on the other hand, travels — a chainsaw carries for kilometres through still night air.
That is why every Jehonë sensor node starts with a microphone. Acoustic monitoring covers ground that no feasible number of cameras or rangers could, day and night, in fog and darkness, without anyone having to be there.
From sound to signal
Listening is only half the job; understanding is the other half. Each node classifies what it hears on the device itself: chainsaw, gunshot, vehicle, or the ordinary life of the forest. Only the verdict — a label, a confidence score, a timestamp and a location — travels over the network.
Raw audio never leaves the node. This is a deliberate design choice with two consequences that matter: the network stays usable on fragile rural links because it carries grams instead of kilograms of data, and the forest keeps its privacy — conversations, voices and everything else are discarded where they were heard.
Knowing where, not just what
A detection without a location is only a rumour. When several nodes hear the same event, the platform triangulates its position from the differences in arrival time — no GPS required on the threat itself, and no dependence on mobile coverage.
The result appears on the command map as a living event: what was heard, how confident the classification is, and where it sits relative to ranger teams, roads and protected boundaries.
What happens next
Detection is the beginning of a response, not the end of a pipeline. Events flow into an alert inbox where they are acknowledged, assigned and tracked — and every step is written to an audit trail so the whole chain of decisions can be reviewed later.
In our field exercises in the Kukës and Tropojë districts, we rehearse exactly this loop: detect, locate, notify, verify. The technology earns its place only insofar as it makes the rangers faster — everything else is scaffolding.
- Detect — the node classifies the sound on-device, in seconds
- Locate — overlapping nodes triangulate the position
- Notify — ranger teams receive an actionable alert with a map
- Verify — the outcome feeds back into the record

How the detection pipeline is engineered so that the minutes that matter most are never wasted — from edge classification to the ranger’s phone.
Designed with rangers, for rangers
Technology earns its place in the forest only if the people who protect it can use it half-asleep at 3am. How field work shapes every screen we ship.
