High mountain rivers and streams
High mountain streams and rivers have one main characteristic: their flow is highly influenced by snow. As a result, the water volume changes significantly throughout the year, peaking in spring when the snow melts rapidly, which can cause major floods. Extreme conditions at the headwaters These ecosystems, especially at the headwaters, can freeze completely or…

Restoration of mires in the Pyrenees: stopping the invasion of trees
The subalpine mires of the Pyrenees are wet ecosystems characterized by the accumulation of decomposing organic matter. Currently, around 27% of the mires in the Central Pyrenees host adult pines, compared to 11% in the mid-20th century. The invasion of trees and the densification of these populations endanger the health and functionality of these ecosystems.…

Published the third brochure of the project
The high mountain lakes are isolated from the rivers below by physical barriers that have prevented fish from colonising them naturally. However, we find fish in a substantial number of lakes as a result of a historical process of introduction. In addition to being introduced species, they are considered invasive species, as they have a…
