Vegetation surveys in mountainous area (Pyrenees, France)

Description :

 The data file contains absolute cover percentage of plant species from vegetation survey in the Vicdessos mountainous area (Pyrenees, France). The data have been collected in 2015 and 2020 within the framework of two projects: ANR-10-JCJC-1804 MODE-RESPYR (Modeling Past and future land cover changes in the Pyrenees) and the PASTSERV project funded by the Observatoire Hommes-Milieux Pyrenées Haut Vicdessos (Labex DRIIHM ANR-11-LABX0010). 
All observed vascular plant species were listed and the cover of each species was estimated using the seven degrees of the Braun-Blanquet scale (r, +, 1, 2, 3, 4, 5). These codes were then converted to absolute percentage cover (van der Maarel 1979).

Project :
Title : MODE RESPYR/ PASTSERV
Abstract : Few studies have explored the effect of historical land-use on past and modern plant and animal dynamics, as well as their long-term ecological functions, especially in mountain areas. Even rarer are those which integrate the spatio-temporal evolution of ecosystems over more than a hundred years. To do this, PASTSERV, an interdisciplinary exploratory project, will combine several recent models developed in paleoecology, geography and ecology to produce historical land-cover and ecosystem services maps in the sector of Bassiès for the last 200 years. PASTSERV will compare the reconstructed trajectory of past ecosystem services with a set of possible trajectories. This approach will advocate the usefulness of long-term approaches to achieve a good level of understanding of the effect of pastoral activities on the dynamics of flora diversity, the production of ecosystem services and the multifunctionality of the Bassiès pastures. The project will seek in particular to understand whether the bouquet of ecosystem services has varied over time following the abandonment of pastoral practices. Has the range of potential services necessarily decreased over the past 200 years?
