5. Kilpisjärvi Biological Station GEOGRAPHY II Kilpisjärvi lies c. 473 metres above sea level Landscape is mosaic of treeless mountain heaths, willow bushes and small lakes and ponds Landscape dominated by fjelds, such as Saana (1029m) and Halti (1328m) Large rivers: Könkämäeno, Poroeno, Rommaeno and Lätäseno

6. Kilpisjärvi Biological Station GEOLOGY Rocks in the Kilpisjärvi region (400-500 million years old) are remarkably younger than in the surroundings (up to 2 billion years old) Rockbed is in connection with the Scandinavian mountain ridge Basic metavolcanic rock Dolomite Arkose quartzite Shale and slate Sandstone and blueish quartzite

7. Kilpisjärvi Biological Station CLIMATE I Kilpisjärvi is one of the coldest places in Continental Europe measured by annual mean temperature For example: Abisko (Sweden) 385 m. a.s.l. -1,0  C Finse (Norway) 1222 m a.s.l. -2,0  C Kilpisjärvi (Finland) 480 m a.s.l. -2,3  C The annual mean temperature in Kilpisjärvi in 1952-2002

8. Kilpisjärvi Biological Station CLIMATE II Mean temperatures: January (-13,6  ), February (-12,5  C) June (+7,5  C), July (+10,9  C) Yearly precipitation: 450 mm Length of growing season: 100 days Snow cover from mid-October to early-June No sunrise between 25 Nov and 17 Jan, continuous sunshine from 22 May to 22 Jul

12. Kilpisjärvi Biological Station NATURAL HISTORY - FLORA Flora Major biotopes: Mountain birch forest Mountain heaths Marshland Factors affecting the vegetation 1. Continental-maritime divide= Very continental climate (cold winters, warm summers) but the proximity of sea (50 kms) affects the vegetation (lot of winter precipitation) Grayleaf Willow (Salix glauca)

14. Kilpisjärvi Biological Station NATURAL HISTORY – FLORA III For more images, see: www.kilpis.helsinki.fi www.kilpis.helsinki.fi Some 450 vascular plant species in the Kilpisjärvi region of which 28 species found only there Lapland Buttercup (Ranunculus glacialis) Lapland Rose Bay (Rhododendron lapponicum)

15. Kilpisjärvi Biological Station NATURAL HISTORY - FAUNA Fishes 13 breeding species, many lax species Amphibians & Reptiles Only common frog and lizard found, both adapted to the northern climate Birds 188 species observed 97 of which regular breeders Mammals 24 breeding species (e.g. the Norwegian lemming and the Arctic Fox) Redstart (Phoenicurus phoenicurus) Photo: Josef Timar

17. Kilpisjärvi Biological Station HOW DO PEOPLE LIVE? I INHABITATS The Commune of Enontekiö: 2150 Kilpisjärvi: <100 Lots of seasonal workers from March to September 70 % OF THE SURFACE AREA OF ENONTEKIÖ PROTECTED Käsivarsi wilderness area, Pallas-Ounastunturi national park, Malla strict nature reserve and other protected areas OVER 36 000 TURISTS YEARLY + OTHER VISITORS

18. Kilpisjärvi Biological Station HOW DO PEOPLE LIVE? II Shopping-tourism from Norway (some 100 000 in 2002) Passing cargo from Norway to Finland and Sweden In spite of remote location, Kilpisjärvi is a very popular place among visitors and tourists Norwegian settlements in the village Tourism and trade major sources of income Hiking Centre

19. Kilpisjärvi Biological Station ECONOMY Main means of livelihood Tourism: Hotels, accommodation, transport Trade: Shop, gas station, cafés Public services: Border guard, customs, Forest Research Institute, Forest and Park Service, Biological Station, Kilpisjärvi School Reindeer herding: Not significant Rate of unemployment in Enontekiö: 19,7 % (2002) Lot of construction in 2003-

20. Kilpisjärvi Biological Station TRANSPORT By airplane and taxi Kittilä or Hetta (Enontekiö) By train and bus From Kolari or Rovaniemi Distances Rovaniemi: 470 kms Kolari: 290 kms Kittilä: 270 kms Hetta 180 kms

21. Kilpisjärvi Biological Station ENVIRONMENTAL THREATS I Main biotopes: Treeless mountain heaths (75 %) Sub-alpine birch forest and willow bushes (14%) Marshland (10%) Lakes and ponds (4%) Biotopes have suffered little of human activities due to the remote location: No power plants, no oil emissions No heavy industry, no emission of heavy metals No large establishments Very little fall-out of pollutans from Kola Peninsula

22. Kilpisjärvi Biological Station ENVIRONMENTAL THREATS II POTENTIAL THREATHS IN THE FUTURE: 1. Construction Impossible in large parts of the Kilpisjärvi area (protected areas). Locally a possible threat 2. Global change of climate Potential risk 3. Grazing of reindeers Potential risk for rare alpine plants? Over-herding in the late 1980’s, at the moment the amount of reindeer only 50% of that

23. Kilpisjärvi Biological Station ENVIRONMENTAL THREATS III POTENTIAL THREATHS IN THE FUTURE: 4. Disturbance (snow mobiles, tourism) Potential risk for breeding of rare birds (Gyrfalckon etc.) Mechanic erosion in the hiking tracks and around wilderness huts 5. Increase of transportation Is limited in the proximity of the main road Air traffic (airplanes, helicopters)

24. Kilpisjärvi Biological Station INFRASTRUCTURE OF STATION I The four station buildings comprise 1600 m 2 Seismic station of the University of Helsinki Four laboratories, computer room, library, offices and catering centre in the main building. Three separate accommodation buildings Accommodation for some 60 people Two lecture halls for either 30 or 60 people Laboratories equipped with basic laboratory equipment. Wide variety of field equipment is available.
