- Abstract
A bryological survey of Barrès Beech forest (Ardèche) was performed. 96 bryophyte taxa were observed among which several remarkable species, such as Seligeria recurvata, S. calcarea or Serploeskea confervoides. Orophilous taxa are well represented within this mountain enclave in the heart of Mediterranean vegetation. This is a biogeographic originality. Bryophyte assemblages are described and compared with abyssal Beech-wood of Sainte-Baume or Massane. The virtual absence of dead-wood bryophytic communities and the scarceness of corticolous assemblages are underlined. The originality of Barrès bryophyte flora could significantly be improved as a result of adequate forest managment. In the strict nature reserve, non-intervention type of managment is recomended. Outside the reserve, restructuring by selection of best branches in multi-trunks trees and a more irregular management are pointed as main objectives.
