Summary:

Riverline woodland habitats are extremely valuable in terms of ecology, and many of them are included to the Natura 2000 network. Unfortunately, in recent decades water conditions on these areas have considerably changed, what is causing their degradation. For that reason, studies on differentiation of habitats determined by variable water conditions in flading areas have been curried out. The case study was Oława-Lipki flood polder, covered with forest. This article presents an analysis of water and habitat conditions executed in years 1997–2000.
