Environmental forests beyond the Arctic treeline in Norway
Abstract
Since 1984, seedlings of a number of hardy species and provenances were transplanted in small openings in a willow thicket at Vardø on the Arctic coast of Norway (70oN) both in provenance experiments with Betula pubescens var tortuosa and with Alaskan provenances of Picea engelmannii, P. glauca, P. sitchensis, P. x lutzii, as well as of Abies lasiocarpa and a northern Norwegian provenance Picea abies. In 2000, after fifteen years of growth about 70% of the sheltered plantations survived, and the average tree height was then of the order of 1 meter, which was still mainly under the maximum snow cover. However, during some winters/springs the evergreen branches were somewhat damaged and partly turned brown. Most vigorous seemed to be some "blue" coloured northern Alaskan provenances of Picea x lutzii and P. glauca,while Abies lasiocarpa and Larix siberica seem to have a strong tendency to form several apical shoots
