streszczenie
Wełtyń Plan is a typical agricultural region with intensive cultivation and fertilization. This causes different landscape changes as a result of application of high doses of mineral fertilizers and pesticides. Presented results were collected in the years 1995-2003. On the studied area 95 small midfield ponds were analyzed considering factors threatening the correct functioning of small ponds such as: changes of ponds forms, transformation (devastation and degradation) of plant cover introduced by different kinds of contamination. Summing up, it was ascertained that flora relatively quickly responded to changes in the environment caused by agricultural activity.
