NATURE & PHOTO: JOSEF TIMAR ENVIRONMENT The unique nature of the Kilpisjärvi area was one of the reasons why the Biological Station was founded there. Kilpisjärvi is the only part of Finland extending into the Scandinavian mountain ridge. Rocks containing limestone are abundant in the area. Kilpisjärvi belongs to the subalpine birch forest zone, mountain birch being the dominant plant species. The majority of the area is a mosaic of treeless alpine heath and ponds. The climate is arctic and the annual mean temperature is only -2.3°C which is one of the lowest in Continental Europe. The length of the growing season is 100 days, which is about half the length of growing season in southern Finland. The ground is covered with snow on an average from mid-October to early-June and Lake Kilpisjärvi is covered with ice on average from November to mid-June. In summer, the sun shines without setting for about two months from 22 May to 27 July, but remains below the horizon from 25 November to 17 January, respectively. In spite of the relatively low number of plant species, many rare arctic-alpine calcophilic plant species are numerous in the area. In this sense the Kilpisjärvi region is unique in the scale of all Fennoscandia. Rare plants are the Glacier Buttercup, the Lapland Rose Bay and the Small-white Orchid (image). Just as the number of plants species, the number of animal species also decreases HOW TO GET HERE? There is a regular bus service to Kilpisjärvi departing either from Rovaniemi (440 km) or from Kolari (280 km). There is also a regular taxi service from either Kittilä (280 km) or from Hetta, Enontekiö (180 km). For detailed information, please check our websites. towards the North. In spite of this, there are many breeding animal species, the distribution of which concentrates in the North and in the Kilpisjärvi area. Such species are the Gyrfalckon, the Ring Ouzel and the Bluethroat, the density of which is highest just in the Kilpisjärvi area. The Norwegian lemming, being best known for its mass occurences, is a very typical species in this area. The regular fluctuation of small rodent densities in the cycles of 4 or 5 years affects the breeding of many avian and mammalian predators. The Reindeer are the common herbivores in the area, whereas the Wolverine, the Ermine and the Least Weasel are typical mammalian predators. In addition, some 16 specialized butterfly species are only found in the Kilpisjärvi area in Finland.

KILPISJÄRVI BIOLOGICAL STATION CLIMATOLOGICAL DATA LOCATION THE STATION RESEARCH ACTIVITIES Kilpisjärvi Biological Station is situated in the northwestern-most part of Finland, in the municipality of Enontekiö. Here the landscape is dominated by fjells extending into the Scandinavian mountain range, such as the Saana Fjell (1029m) and the Pikku-Malla Fjell (738m). Kilpisjärvi lies 473 metres above sea level. The Kilpisjärvi Station, established in 1964, is a scientific research station belonging to the University of Helsinki. The principal aim of the station is to promote biological and geographical research in the north as well as to provide students of biology and geography with information about natural phenomena. The station is open to researchers of all nationalities in all branches of science. The four station buildings comprise 1600m2. The main building has been renovated in 2003. The main building has two lecture halls (with space for either 30 or 60 people), a computer room, library, catering centre and laboratory facilities. In the main building and three separate buildings, there are bedrooms for a busload of people. The Station has four laboratories, which are equipped with basic laboratory equipment. A wide variety of field equipment is also available. For more information, please see our websites. Widely respected, long-term followup studies form the core of the scientific activities at the station. The most long-lasting series of observations concerns the fluctuations of the small rodent densities over a 50-year period. Futhermore, the population dynamics of passerines have been monitored since 1957. Long-term research projects also include the periodicity in the quality and quantity of vegetation in the mountain region. Recent research activities have extended from animal and botanical ecology into hydrobiological and paleolimnological research. In addition, regular studies on geography and geophysics has been conducted at the station. Seismic station of the Institute of Seismology is situated at th Biological Station. The Station also publishes its own newsletter, “Kilpisjärvi Notes”. THE SAANA FJELL. UP-TO-DATE FACILITIES ARE SUITABLE FOR COURSES OR SYMPOSIA.
