English title: Protection forests IAbstract
The article aims to give a proposal on how to organize a protection forest system to protect the pine timber line in the northernmost Finland. In this first part of the six-article series is described the range and biology of Scots pine (Pinus sylvestris L.) in the timber line area, and human actions influencing the species in the area. The southward shift of Scots pine timber line cannot be explained by change of climate. The main factors are too intensive fellings, reindeer husbandry and forest fires. The poor reproduction of pine in Lapland makes it vulnerable to disturbances. The trees produce viable seeds in average only every 100 years. Thus, effective measures are needed to protect the existing pine forests in the area.
The article is divided in six parts. A German summary is in a separate PDF.
