Méthodologie de suivi des espèces végétales rares mise en place par un réseau d’acteurs de la conservation

Abstract

AbstractThere is an increasing need for data on the patterns of population changes for rare species at the regional, national and European scales in the context of the Natura 2000 reporting on the state of species’ conservation. This reporting requires the use of the same protocol over a whole region or country with the major constraint that it has to be shared by a large array of conservations and monitoring structures. The protocol has therefore to be both precise and reproducible but also simple enough to be used over a large number of sites and years, and has moreover to be accepted by various conservation structures.In this aim, the Alps-Ain flora conservation network (Reseau Alpes-Ain de Conservation de la Flore), a network composed of flora conservation stakeholders for 2 regions, Provence-Alpes-Cote d’Azur and Rhone-Alpes, set up a series of nested protocols to monitor populations at different spatial scales (levels). Each monitoring level is set up to answer to a specific aim and corresponds to a...
