General Site Description: 

The Lammi LTER area is located 130 km north of Helsinki, 35 km east of the city of Hämeenlinna and 40 km west of the city of Lahti in uplands between two major river basins, i.e. rivers Kokemäenjoki and Kymijoki. The Lammi LTER area consists of several core sites/areas from which the Evo Forest and Lake Area (EVO) is the largest one and has a special value in terms of long term ecological studies. Another important study area is Lake Pääjärvi and its surroundings. The EVO area is among the largest coniferous forest areas in southern Finland. Lake Pääjärvi and its surroundings have been studied since early 1960s as a result of the establishment of the Lammi Biological Station in 1953 by the University of Helsinki.

Purpose of Site : 

The aim of the Lammi LTER site is to enhance and deepen our understanding on the key biogeochemical and physical processes and their interaction and coupling with organisms, populations and ecosystems along space and time in the context of global change and multiple environmental stressors in the southern Boreal Zone. Thus, the Lammi LTER site will provide reliable multi-variable information on the ecosystems and their compartments in relation to unstable environment both in terms of time and space, and in particularly due to the gradual changes in our physical, chemical and biological environment caused by the human society. The research themes involved in the Lammi LTER site are: i) meteorology and lake physics, ii) biogeochemical processes, iii) climate change impacts and greenhouse gases fluxes, iv) biodiversity studies, v) ecosystem and landscape studies, vi) human-ecosystem interactions and forecasting long term changes, vii) demographic structure of fish populations in small forest lakes, and viii) natural long-term changes in food webs of small forest lakes.
