The project consists of listening to bats to develop a bio-indicator specific to wetlands.

When nature works for Nature

Wetlands represent a very important ecosystem for the populations of Chiroptera, more commonly known as bats. The 34 species found in France are all protected, and use wetlands every day to drink and hunt.

Consequently, they are sensitive to any deterioration in the aquatic ecosystems due to the accumulation of pollutants. Tracking the populations of bats can provide information on the wetlands’ quality and be used to develop relevant indicators. 

Using advanced technology to listen to bats

The Centre for Ecology and Conservation Sciences (CESCO) aims to develop a bio-indicator specific to wetlands, based on the analysis of the data accumulated over the past 10 years by the Vigie-Chiro programme, a participative network of acoustic recordings of bats’ hunting activities.

The project uses technologies in the forefront of bioacoustics with live recordings at very high frequencies. The automatic signal processing tools use artificial intelligence processes, such as machine learning.
The members of the jury were thrilled by the innovative aspect of the project, as well as its use of data produced by a participative sciences programme.

The winning team

The Centre for Ecology and Conservation Sciences (CESCO) conducts researches into the preservation of biodiversity and the main mechanisms that govern it. These questions are addressed from the perspective of the ecology and evolution, but also of the human and social sciences.

CESCO is the laboratory of the Ecology and Biodiversity Management Department of the French National Museum of Natural History (MNHN). The MNHN is an historical institution founded in 1635, at the crossroads between the Earth, Life and Human Sciences, with a mission to better understand and valuate nature and, therefore, to better protect it.
