The Amazon is one of the most biodiverse places on Earth

The Amazon rainforest is the world's most important natural ecosystem. It represents half of the world's tropical forests and is home to more than 3 million species. It has the greatest diversity of plant species on the planet and the Amazon river system holds 20% of the world's unfrozen fresh water. It is also one of the last refuges for many endangered species such as the jaguar, the saki satan and the pink dolphin. The Amazon rainforest plays a key role in the planet's climate.

Tropical forests are rapidly disappearing from our planet

Rainforests are disappearing because of deforestation from logging, mining, oil drilling, agriculture and expansion of urbanized areas. 50% of the world’s rainforests have been destroyed in a century. Scientific insights are lost before they can be revealed when countless more species are yet to be discovered.

With an area of 8 million km2, the Amazon rainforest surface is equivalent to 14 times France's territory

Monitoring the sound of the whole Amazon rainforest to preserve its biodiversity

Listening to the sound of life, the only support of information that all living creatures share, animals and plants, aquatic or terrestrial, allows to assess the health status of nature. Project Providence revolutionizes the way biodiversity is monitored by installing under the canopy a wireless sensor network of autonomous acoustic observatories. Through a technology called Providence Nodes, which automatically capture, process and identify in real time any sound, both on land and underwater. The processed data is then sent over the internet and made available worldwide.
