The aim of the study was to verify a hypothesis that the proximity of different ecosystems have an
impact on the richness of flora in three forest patches in the Choszczno Forest Inspectorate (West Pomeranian Province in NW Poland). Between 2013–2015, the survey involved three areas with different adjacent
ecosystems: forest, built−up area, and grassland. At each object we analyzed four test plots consisting of
inner, middle and outer zones. The composition of tree, shrub, herbaceous, moss and lichen species was
determined in each object, plot and zone. It was shown that adjacent ecosystems influenced the richness of
flora in the analyzed forest areas. Differences in the numbers of species and in their habitat affiliation were
also found between ecotone zones. The outer ecotone zone had the richest flora composition, particularly in
terms of grassland species – present in 12 zones of all three objects.
