Dear Maurizio,
I do not know which taxa you are interested in. May I suggest that you specify your question in this regard.
The global biodiversity information facility (http://www.gbif.org/) is always a good starting point. Otherwise check "species occurrence data at the diva-gis website http://www.diva-gis.org/Data
I hope this helps.
Cheers
Darius
Hi Darius, many thanks for your answer. I'm looking for data about Pinus nigra, Douglas fir and Fagus sylvatica.
Hi Maurizio,
the key adress is efi.int with. Several projects deal with this kind of problems. First of all it's an issue of terms and definitions:
http://www.efi.int/files/attachments/publications/ir_13_bw.pdf
Then several maps have been created: Maps + data (including beech, but no on so called minor species, like this one for instance:

Maps are available at: efi.int Data most probably upon request, I think!

Dear Maurizio,
try doing a search with these keywords
ONF NFI douglas fir
(Office National des Forets-France)
(National Forest Inventory)
Kind regards

The species you are looking for are well represented in National Forest Inventories (NFI). I don't know if a joint public database exists, but you may find the NFI datasets ready to download in their webpages (check http://efdac-catalog.jrc.ec.europa.eu/efdac_subthemes.jsp?DI=8) or even in the GBIF data portal (e.g. Spanish NFI, http://www.gbif.org/dataset/fab4c599-802a-4bfc-8a59-fc7515001bfa)
Maybe useful: there is a new tree species atlas of the JRC, and can (for now) be downloaded fully: http://forest.jrc.ec.europa.eu/european-atlas-of-forest-tree-species/
