“…A more pronounced effect of T at low current temperature sum was to be expected (III), because low summer temperature limits growth more in northern than in southern Finland (Mäkinen et al 2002). Similarly, in provenance experiments trees of northern origin have been found to benefit more from increasing temperatures (Beuker 1994). Also in this work (III), the simulations' results were in line with the assumptions regarding Scots pine and silver birch, which reacted to elevated T more vigorously at sites with a low current temperature sum.…”

“…In Beuker's (1994) data, growth increased relative to the natural rate of growth, when trees were taken from northern Finland and transplanted to southern Finland into an environment 2-5 centigrade warmer than the site from which the seed was collected. He concluded that in areas where low temperature is the major limiting factor for increment, tree growth would benefit from an increase in annual mean temperature.…”

“…He concluded that in areas where low temperature is the major limiting factor for increment, tree growth would benefit from an increase in annual mean temperature. Beuker (1994) refers mainly to the responses of trees in the northern parts of Finland (see also Karjalainen 1996a,b).…”

“…The impact will be seen primarily as an increase in growth and productivity resulting from the prolonged growing season (Junttila and Nilssen, 1993;Beuker, 1994;Fries et al, 1998). At the timberline ecotone, the growing season is expected to change from the present 110 -120 days up to 150 -160 days by 2100 (Kellomäki et al, 1997).…”

ABSTRACT. Seedling density, tree density and basal area of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst) were monitored and compared in the timberline areas of northern Finland during the period 1983-99. Rows of 9-12 circular plots were established at 13 localities in four regions: pine-dominated northern and southern regions and spruce-dominated western and eastern regions. Temporal changes were monitored in three altitudinal zones: in the forest, at the coniferous timberline (where forest canopy closure ceases), and at the tree line (where coniferous trees higher than 2 m cease). Pine seedling densities decreased abruptly in the southern region, especially at the timberline, but increased slightly in the northern region. The zone · region · change interaction was significant. The change in spruce seedling densities was small in the forest and timberline zones, but the densities more than doubled at the tree line. Tree density and basal area increased in all the zones and regions. New regeneration and tree establishment during the study period indicate a potential for the tree line to advance. However, there was great heterogeneity in regeneration and seedling establishment among the localities.Key words: climate change, climatic variation, regeneration, Pinus sylvestris, Picea abies, seedling density, tree density, basal area, timberline, tree line RÉSUMÉ. La densité des semis, la densité des arbres et la surface terrière du pin sylvestre (Pinus sylvestris L.) et de l'épinette de Norvège (Picea abies [L.] Karst) ont fait l'objet d'une étude et d'une comparaison dans des zones situées à la limite de la forêt de la Finlande septentrionale durant la période allant de 1983 à 1999. Des rangées de 9 à 12 parcelles circulaires ont été créées à 13 sites répartis dans 4 zones: les régions septentrionale et méridionale où dominait le pin sylvestre, et les régions occidentale et orientale où dominait l'épinette de Norvège. On a mesuré les changements temporels dans 3 zones d'altitude différente: dans la forêt, à la limite de la forêt de conifères (là où cesse la fermeture du couvert forestier), et à la limite des arbres (là où cessent les conifères de plus de 2 m de haut). La densité de semis du pin sylvestre diminuait brusquement dans la région méridionale, en particulier à la limite de la forêt, mais elle augmentait légèrement dans la région septentrionale. L'interaction zone-région-changement était significative. Le changement dans la densité de semis de l'épinette de Norvège était faible dans la forêt ellemême et dans les zones de la limite de la forêt, mais la densité avait plus que doublé à la limite des arbres. La densité des arbres et la surface terrière augmentaient dans toutes les zones et les régions. Une nouvelle régénération et un nouvel établissement d'arbres durant la période d'étude révèlent que la limite des arbres pourrait progresser. Il y avait toutefois une grande hétérogénéité dans la régénération et dans l'établissement des semis parmi les divers sites.
