| Title | Mountain lakes of Mont Avic Natural Park: ecological features and conservation issues |
| Abstract | Mountain lakes provide some fundamental ecosystem services (i.e., water supply for drinking and energy production) and have an
enormous aesthetic and conservation value. Ecological knowledge on mountain lakes, however, is still scarce and limited to a few
geographical areas and mainly to abiotic features. To fill this gap, a limnological campaign was carried out on 19 lakes of the Mont
Avic Natural Park (Aosta, Western Italian Alps). Bathymetric maps of the lakes are provided in this paper, as is data on the lakes'
physical properties, chemistry, nano- and pico-plankton, zooplankton, littoral macroinvertebrates, amphibians and introduced fish. The
aim of this study was to create a reference database of ecological data for the development of new studies and conservation
measures/actions. To this end, ecological data are discussed from both a limnological and a conservation perspective, allowing for the
identification of major threats affecting the lakes in the protected area. Despite local threats which include water exploitation, organic
pollution, and introduced fish, water quality was good. Lake biota can however be affected by such threats, in particular introduced fish
(Salmonidae and Cyprinidae), representing a challenging conservation problem. |
