Abstract
In the years 2000–2002 floristic and phytosociological investigations were carried out
around of eleven permanent sites in the Ina River valley between villages Sowno and
Przemocze. Nineteen phytocoenosis on the eleven humidity habits were selected. Ascertain
ecotone zone of vegetation were dependent on site. The biggest surface were occupied by the
floral assemblage situate the most closer to the Ina River on the fresh and wet habitation. Next,
along with distance accrue ascertain occurrence of strong wet and wet habitation as well as dry
seasonally humidified habitation on the higher areas of researched area. The high value of
synanthropisation and apophytisation indexes indicated the negative changes on the meadows
communities. Two protected plant species and ten protected animals species (including insects,
amphibians, birds) were found on the studied area.
