Summarry of the thesis

The main objectives of this program are :

• A database development upon the vegetation of Nord, Pas-de-Calais, Somme and Aisne départements.
• The description of primary and secondary vegetation succession in these territories.
• The identification of spatial connectivity of these series by detection of teselas and catenas (symphytosociology).
• The building of a database upon landscape patterns of these regions.
• The production of Mendeleïev tables upon these territories to illustrate the dynamic and topographic links of identified vegetation.
• The statistical check of the synusia-phytocenosis-tesela-catena model in the study area.

This project is a part of the CarHAB program of the Ministry of Ecology, which aims to map the terrestrial natural and semi-natural habitats of France at 1/25,000.
