eVeg is a web interface about baseveg data (CATMINAT program, by Philippe Julve).
It gives you access to a database about french's vegetations extended to Europe (holartic and eurasiatic for some units) and is founded on integrated synusial phytosociology principles.
Each known vegetation is described (ecology, geographical repartition, synonyms, blbliography) and comes with some illustrations and diagnosis tables (work in progress : your help is welcome).
