Hydrosère

Une hydrosère est la succession végétale qui se produit dans un lac d'eau douce. Avec le temps, un espace ouvert d'eau douce comme un lac va naturellement se combler et devenir à terme une forêt. Au cours de ce changement, qui prend des centaines, voir des milliers d'années, une gamme de différents milieux se succèdent tels que les marécages et marais.
La succession va de l'eau ouverte au climax, qui peut être une forêt.
On utilise aussi ce terme pour désigner la succession végétale au niveau spatiale, du lac à la forêt.
