Abstract

Typical for the area of Längälmävesi, in Satakunta in Southern Finland, are densely populated fertile lowland areas near the waterways and poorer sparcely populated upland areas. The changes in fertility of the land influence the vegetation, and has directed where the population has settled. A vegetation survey was made using specific plant species as indication to fertility. A detailed description of the species composition and distribution of the plant species indicative for fertile land is presented in the article.

Analyzing the fertility only based on the plant species indicative for rich soils underestimates the proportion of fertile lands. Farmlands, on the other hand, have been cleared also on less fertile soils, which would give an overestimate of the fertile lands. A map of fertile lands was drawn based on both vegetation and location of the fields. The changes in fertility influenced also bird species observed in the area.
