Les classes sociales des arbres selon Kraft :\u00a01 super-dominant ; 2 dominant ; 3 co-dominant ; 4 domin\u00e9 ; 5 compl\u00e8tement domin\u00e9.
\nLe h\u00eatre est l’une des essences foresti\u00e8res les plus importantes \u00e9conomiquement en Europe centrale. Cependant, cette essence pr\u00e9sente une forte sensibilit\u00e9 \u00e0 la s\u00e9cheresse et sa capacit\u00e9 \u00e0 faire face aux \u00e9pisodes secs est incertaine.
\nUne \u00e9tude en Allemagne s\u2019est pench\u00e9e sur le sujet et a \u00e9tudi\u00e9 plus pr\u00e9cis\u00e9ment la tol\u00e9rance du h\u00eatre \u00e0 la s\u00e9cheresse de 2003 en fonction de plusieurs facteurs et en particulier l’intensit\u00e9 de l’\u00e9claircie. La croissance de 126 arbres adultes a \u00e9t\u00e9 mesur\u00e9e en comparant plusieurs facteurs : la classe sociale des arbres (super-dominant, dominant et co-dominant), la station (s\u00e8che et humide) et l\u2019intensit\u00e9 d\u2019\u00e9claircie (t\u00e9moin, \u00e9claircie forte et tr\u00e8s forte).
\nLes r\u00e9sultats de l\u2019\u00e9tude montrent que les arbres co-dominants et dominants ont une croissance plus faible et se sont moins bien r\u00e9tablis apr\u00e8s la s\u00e9cheresse, par rapport aux arbres super-dominants. Au niveau des stations, les arbres en station s\u00e8che pr\u00e9sentent une croissance plus faible, mais une r\u00e9silience plus grande face \u00e0 la s\u00e8cheresse par rapport aux arbres situ\u00e9s sur station humide, ce qui met en \u00e9vidence un compromis entre la croissance et la tol\u00e9rance \u00e0 la s\u00e8cheresse.
\nEn ce qui concerne le traitement sylvicole, les r\u00e9sultats sugg\u00e8rent clairement que la r\u00e9sistance et la r\u00e9silience apr\u00e8s la s\u00e9cheresse de 2003 ont consid\u00e9rablement augment\u00e9 pour les arbres \u00e9claircis. En conclusion, l’\u00e9claircie peut att\u00e9nuer partiellement les effets de la s\u00e9cheresse s\u00e9v\u00e8re sur les h\u00eatres et peut donc \u00eatre appliqu\u00e9e comme mesure d’adaptation.
