AI-powered Tech is Tackling Illegal Logging in Rainforests

Illegal logging is the third-largest transnational crime, generating between US$50bn and US$150bn annually. 

It not only contributes to widespread deforestation but also accelerates climate change by reducing the planet’s natural ability to store carbon.

Rainforest Connection’s (RFCx) solar-powered AI platform, Guardian, is designed to detect illegal logging in real time, helping conservationists and local authorities respond quickly to threats. 

By using advanced acoustic monitoring and machine learning, Guardian provides a scalable solution to protect forests and the biodiversity they support.

How Guardian works to prevent deforestation

Guardian is an AI-powered device that operates from the treetops, continuously recording and transmitting audio from the rainforest. 

Equipped with solar panels and durable microphones, it collects environmental data for real-time analysis, allowing conservation teams to act before irreversible damage occurs.

The technology is designed to work in extreme rainforest conditions, where heat, humidity and pests create constant challenges. 

RFCx founder and CEO Topher White explains: “While we’re trying to help fight climate change, we have our own battle with nature. The rainforest is a terrible place to put an electronic device. 

“It’s brutally hot, the sun is as dangerous to our devices as it is necessary to power them and termites will deconstruct everything they possibly can just for fun.”

Guardian’s microphones capture the ambient sounds of the forest within a radius of 50 to 1,500 metres, detecting patterns associated with illegal activity. 

It transmits this data via Global System for Mobile Communications (GSM) or satellite, where AI processes the recordings to identify potential threats. 

When Guardian is connected via satellite, its on-board system performs an initial analysis before sending alerts in real time.

Topher highlights: “Arm technology allows us to pick up all the sound of the forest 24 hours a day, package it up and send it up into the cloud over any network that’s available, where we then use AI to analyse it. 

“It plays a vital role in this constant connection between us and the rainforest and allows us to alert rangers of environmental threats in real time.”

By detecting the sound of chainsaws, trucks, gunshots or other indicators of illegal activity, Guardian enables conservation teams to respond swiftly, preventing deforestation and habitat destruction before they escalate.

Built to endure rainforest conditions

For Guardian to function effectively in remote and hostile environments, it is constructed using custom-designed components that prioritise resilience and efficiency.

Its solar panels are specifically engineered to make use of the limited light that penetrates the dense canopy, ensuring uninterrupted power. 

The device includes several key features to maintain reliability:

• IP66 weatherproof enclosure: Protects against rain, humidity and extreme temperatures
• Wi-Fi, Bluetooth, GPS: Enables remote tracking and data access
• Built-in satellite communications (SWARM): Allows connectivity in areas without mobile networks
• On-board accelerometer: Detects and alerts against tampering attempts
• Solar panel array: Generates up to 30W of power to sustain continuous operation
• Battery storage: Two on-board batteries store 50WH of energy for night-time use
• Custom power board: Manages energy distribution and optimises battery life
• Aluminium mounting frame: ​​​​​​​Secures the device high in the canopy for optimal data collection.

These features ensure that Guardian can operate autonomously for extended periods, continuously monitoring forests without the need for frequent maintenance.

The impact of AI-powered forest monitoring

RFCx has deployed Guardian devices in 587 tree canopies across 37 countries, monitoring a total of 736,200 hectares of protected land. 

This translates to the conservation of more than 1.8m acres, safeguarding crucial carbon storage and biodiversity.

Through continuous acoustic monitoring, the platform has recorded 160 million audio files, identifying 4,208 species, including 408 classified as near-threatened, vulnerable, endangered or critically endangered. 

As Guardian’s machine learning capabilities improve, the system can now detect 955 species automatically, with this number expected to rise over time.

Highlighting the urgency of conservation, Topher says: “There is no solution to climate change unless we protect rainforests.

“That doesn’t mean that we regrow what we’ve lost. That doesn’t mean we can cut them down and then grow them back. It means they have to stay in place, as they are. That’s a fact, and it’s this fact that drives us.”

Forests play a critical role in capturing and storing carbon, making deforestation a major contributor to rising global emissions. 

By leveraging AI and real-time acoustic analysis, RFCx’s Guardian platform provides a powerful and scalable approach to combating illegal logging, protecting biodiversity and strengthening global conservation efforts.
