Shortlist from Station Catalogue over facilities and science disciplines.
STATION NAME AND OWNER
Värriö Research Station is managed by University of Helsinki, Department of Physics.
The area is a The area immediately south of the Arctic circle. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climate. In other words, the subarctic is the region between the... More pine forest with several mountains and ridges reaching 500–600 m.a.s.l. The station is located in the Värriö Strict Nature Reserve, and thus access without permission is forbidden. Small lakes, wetlands and rivers are located in the surroundings of the station, which lies in the S slope of a small hill. Nearest population centres and industry, yet in small-scale, are 100 km away.
BIODIVERSITY AND NATURAL ENVIRONMENT
The station is located in a strict Nature reserve, and thus the natural state of the environment in the region is protected. The Alpine tree line (Pinus sylvestris, Betula pubescens subsp. czerepanovii, Betula nana) lies at about 470 m.a.s.l. Below it, old-growth pine forests with some open mires and spruce swamps are the main vegetation types. Open dry A type of ecosystem in which tree growth is limited by low temperatures.

Several rare northern and eastern species nest in the Nature Reserve, e.g. dotterel (Charadrius morinellus).and red-flanked bluetail (Tarsiger cyanurus).
HISTORY AND FACILITIES
The station was established in 1967 when the first log cabin of 50 m2 was built in the middle of wilderness. Later on, the station has been extended and currently it can accommodate ca 20 researchers indoors and more outdoors in tents. There are small but efficient working facilities for indoor research work including e.g. wireless network, workstations and reference library. The station is connected to the main electricity network but has also a generator for exceptional cases. The station has staff on duty every day year around. The nearest commercial facilities such as grocery store and health centre are located 100 km away in Savukoski village.

The nearest local village is Savukoski, about 100 km SW. The forests in the close-by region are in intensive use of forestry and reindeer husbandry. The nearby Urho Kekkonen National Park and other protected areas as well as fish-rich rivers fascinate large numbers of tourists annually. Recently, there have been plans for opening a large open pit phosphorus mine and a concentration plant in the close vicinity of Värriö Strict Nature Reserve.
The station is accessed by foot (summers) or by skis (wintertime), assistance with snowmobile or a quad bike is available for instruments and larger luggage. The walking distance from the nearest (unpaved) road to the station is about 7 km. The distance to closest airport (Rovaniemi) is about 300 km and to the nearest railway station (Kemijärvi) about 190 km.
