Under the European Nature Restoration Regulation (NRR), European Union member states have until
2040 to document the condition of all terrestrial, coastal and freshwater habitats listed under Annex
I of the Habitats Directive. In this context, the French Biodiversity Office (OFB) has launched several
programs, including the one proposed here, with the participation of national institutions. The CarHab
program will be one of the key tools for mapping these habitats. However, it has become apparent
that CarHab is not sufficiently effective at identifying complex habitats such as scree slopes. We
therefore propose to combine the skills and expertise in habitats and remote sensing held by CESBIO
and National botanical conservatory of the Pyrenees and Midi-Pyrénées (CBNPMP) to investigate a
complementary methodology to better map scree slopes and assess their potential condition
(degradation) with the collaboration of the LESSEM (INRAE).
Consequently, the objectives of this study are as follow, order by priority:
– to establish a knowledge database on scree habitats – of which there are five in this study – using
existing data (surveys and maps) held by various botanical conservatories and, where possible,
through field surveys
– to develop a multi-resolution classification method for the five Annex 1 habitats, using optical
satellite imagery and environmental data (topography, geology, etc.)
– to validate the maps through several field trips in different eco-climatic contexts
– to assess, as far as possible, the conservation status of these scree slopes in light of the pressures
and recreational activities to which they are subjected
