English title: Vegetation and flora in the planned national park of Rokua in Northern FinlandAbstract
The 4.4 km2 sized area of Rokua is a sandy ridge situated in the transitional zone between Central and Northern Finland. It has been suggested to become a new national park due to its, in the area unique landscape and geological characteristics.
The vegetation of the area has been little studied. A vegetation analysis was performed in 1945, 1947 and 1949. Due to low nutrients in the sandy soil, the number of species is relatively low, including 236 vascular plants. The climate is continental. Lichen covering of soil in the Scots pine (Pinus sylvestris L.) dominated forests is mostly intact compared to the more northern areas, because grazing of reindeer has been little. Fellings have increased in the surrounding areas of the planned national park. The article includes a detailed description of vegetation and flora in the area.
The article includes a summary in German.
