Une \u00e9quipe de chercheurs a \u00e9tudi\u00e9 la dynamique de r\u00e9g\u00e9n\u00e9ration d\u2019une for\u00eat apr\u00e8s temp\u00eate, dans le Sud-Est de la Pologne. Les donn\u00e9es relev\u00e9es sur la r\u00e9g\u00e9n\u00e9ration naturelle pendant l\u2019\u00e9tude concernaient :
\nD\u2019apr\u00e8s les r\u00e9sultats de cette recherche, pour laquelle les mesures ont \u00e9t\u00e9 relev\u00e9es pendant 7\u00a0ans apr\u00e8s la temp\u00eate, les individus qui \u00e9taient plus grands avant la temp\u00eate ont conserv\u00e9 leur position jusqu’\u00e0 la fin de l’\u00e9tude. Des esp\u00e8ces pionni\u00e8res sont apparues sporadiquement.
\nSept ans apr\u00e8s la perturbation, le peuplement analys\u00e9 \u00e9tait une mosa\u00efque de groupes d’arbres matures qui ont surv\u00e9cu \u00e0 la perturbation et de jeunes fourr\u00e9s denses domin\u00e9s par la r\u00e9g\u00e9n\u00e9ration pr\u00e9existante.
\nLe h\u00eatre, qui \u00e9tait l’une des esp\u00e8ces dominantes dans le peuplement avant la temp\u00eate, a perdu beaucoup d’arbres dans la canop\u00e9e, mais a conserv\u00e9 sa supr\u00e9matie\u00a0en raison de l’importante r\u00e9g\u00e9n\u00e9ration pr\u00e9existante lib\u00e9r\u00e9e par la perturbation.
\nLe charme a tr\u00e8s bien surv\u00e9cu \u00e0 la temp\u00eate et s’est r\u00e9g\u00e9n\u00e9r\u00e9 dans la zone perturb\u00e9e de mani\u00e8re v\u00e9g\u00e9tative et sexu\u00e9e.
\nL’\u00e9rable sycomore, en revanche, est beaucoup plus abondant dans la r\u00e9g\u00e9n\u00e9ration post-temp\u00eate que dans le peuplement adulte avant la temp\u00eate. C’est pour cette esp\u00e8ce qu’\u00a0a \u00e9t\u00e9 constat\u00e9e\u00a0la plus grande diff\u00e9rence de taille.
\nL\u2019\u00e9tude montre ainsi que la r\u00e9g\u00e9n\u00e9ration pr\u00e9existante \u00e0 la temp\u00eate a jou\u00e9 un r\u00f4le majeur dans la dynamique de renouvellement, tandis que les esp\u00e8ces pionni\u00e8res n’\u00e9taient pr\u00e9sentes que ponctuellement.
