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.
