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.

Metsähallitus (Forest Service) decided to protect two areas around Hiisijärvi lake in Eastern Finland already in 1916. Later, a natural park was suggested to be established in the area. A survey of the vegetation in the area was composed in 1931-1932. The total land area of the protected area was 3.5 km3. A vegetation map was drawn based on a nature inventory. A detailed description of the forest site types, peatland types, aquatic flora and the vegetation of the area are included in the article. The calcareous soil promotes rich vegetation. Typical for the area are also rich fens. The area can be divided to a eutrophic and a oligotrophic part.
