English title: Flora and vegetation of the Sinivuori Nature Park in Southern Finland.

The Sinivuori Nature Park, located in the northeast part of the county of Häme in Southern Finland represents the rare fertile forest lands in the country, and belong partly to the so-called centre of herb‐rich forests of Häme. Sinivuori is one of the smallest nature reserves in Finland (64 ha). The detailed vegetation analysis was performed in 1969, supplemented by earlier and later observations. The area was divided into 69 one-hectare squares for the study of the flora and vegetation.

The most common rock in the park is mica schist. The pH of the soil is relatively high, in average 6.6. Thermal-time sum is 1,100–1,200. The vegetation differs to a large extent from the surrounding areas. 169 vascular plants were found in the area, some of which very rare in the area. The paper lists the plants and their abundance in the area, and the vegetation is described by the forest types. Distribution maps are presented for the species.

The PDF includes a summary in German.

English title: Herb-rich forests and their vegetation in northern Pirkkala-Tyrvää area in Southern Finland.

Vegetation inventory was made to study plant species growing in herb-rich forest in northern Pirkkala-Tyrvää area in Southern Finland. The area belongs to a district that is rich in grass-herb forests, where the bedrock is calciferous. Six herb-rich forest site types were identified in the area. The species composition in the herb-rich forests was compared to those in Turku in southwest Finland, and in Ladogda Karelia in Eastern Finland.  The main characteristics of the plant associations were similar, but there were a few species that are common in Pirkkala-Tyrvää area that are rare in the other areas, and vice versa. The district rich in grass-herb forests of Pirkkala may extend more westwards than it has been assessed earlier. Finally, the article lists the plant species found in the herb-rich forests in the area and defines their distribution and abundance.

English title: Distribution of fertile lands and vegetation indicative for herb-rich forest sites in Längelmävesi area in Southern Finland.

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.
