Natural regeneration is of high priority but plantations are still common. The number of<br />
commercialized beech seedlings produced is <strong>de</strong>creasing: 1, 4,000 seedlings in 2008, 2,553,000 in<br />
2005 and 4, 14,000 in 1998. Beech is the most affected species by this phenomenon. It has several<br />
putative origins: (i) high priority for natural regeneration, (ii) fall of plantation <strong>de</strong>nsity, (iii) cost of<br />
beech plantations, (iv) risk with climatic changes and (v) global <strong>de</strong>crease of artificial regeneration in<br />
France.<br />
In France, we have only ‘selected’ seed stands for forest reproductive material. France is divi<strong>de</strong>d in<br />
16 provenance regions and has 169 selected beech seed stands. They cover a surface area of , 16.9<br />
ha (Tab. 4).<br />

The <strong>de</strong>lineation of the provenance regions (Fig. 2) was carried out according to:<br />
– Genetic data for the following provenances regions (Comps et al. 198 , Vernier, Teissier du<br />
Cros 1996, Magri et al. 2006): Nord (FSY102), Nord East (FSY201) and Pyrenees (FSY601,<br />
FSY602 and FSY603);<br />
– Soil conditions (Tessier Du Cros, Lepoutre 1983) for Massif Armoricain (FSY101), Charentes<br />
(FSY301) and North East (FSY201) ;<br />
– Climatic conditions for Massif Central (FSY401, FSY402 and FSY403);<br />
– Soil and climatic conditions: Jura (FSY501) and Alps (FSY502 and FSY503).<br />
