Abstract
Aim Present northern distribution limit of jack pine (Pinus banksiana Lamb.) follows
the northern limit of continuous open boreal forest in western Canada, but not in eastern
Canada where it is located further south. We tested the hypothesis that fire plays a more
important role than climate in explaining the present position of the northern distri-
bution limit of jack pine.
Location An experimental jack pine plantation was set up in 1992, c. 300 km north of
the present distribution limit of the species, in the Boniface river area of northern Queebec
(57°43¢ N, 76°05¢ W).
