\nLe ch\u00eane sessile, essence incontournable de nos for\u00eats, serait-il menac\u00e9 par les changements climatiques annonc\u00e9s ? Une \u00e9tude men\u00e9e conjointement par l\u2019ONF, l\u2019Inra et des partenaires europ\u00e9ens a permis de mettre en avant la r\u00e9silience de cette essence face \u00e0 des variations de temp\u00e9ratures et de pr\u00e9cipitations.
\nUn r\u00e9seau de plantations de ch\u00eanes install\u00e9 il y a 30 ans dans diff\u00e9rents pays europ\u00e9ens issu de 116 origines a montr\u00e9 que cette essence est tr\u00e8s peu sensible aux variations climatiques mais qu\u2019elle ne supporte pas le manque d\u2019eau.
\nIl est \u00e9galement av\u00e9r\u00e9 que l\u2019origine des plants conduit \u00e0 des r\u00e9ponses diff\u00e9rentes face \u00e0 ces modifications : les individus provenant de pays chauds ont une croissance inf\u00e9rieure \u00e0 ceux provenant de pays froids, le climat d\u2019origine contribue donc \u00e0 la diff\u00e9renciation g\u00e9n\u00e9tique per\u00e7ue.
\nDe plus, les zones de survie futures du ch\u00eane sessile ont \u00e9t\u00e9 d\u00e9termin\u00e9es en tenant compte des changements climatiques \u00e0 venir. Seules les populations proches de la limite Nord de son aire de distribution conserveraient une croissance \u00e9lev\u00e9e, les zones au sud verraient la croissance du ch\u00eane, voire leur survie, affect\u00e9es.
