Objectives

The conditions of nature and forestry in northern Finland differ from those in the southern part of the country. Due to cold climate, forest regeneration is slow and growth, yield and revenue of forests are low. Additionally site factors are also different.

Other forest users show a tendency to constrain intensive forestry. Due to generally low profitability and pressure from multiple-use forestry it is well justified to use environmentally friendly, extensive, cost-effective, and profitable methods also in forest regeneration. In forest regeneration this means the use of natural regeneration. In the forest regeneration during the last few decades, study has focused on artificial regeneration, and the study of natural regeneration has been lesser. The purpose of this study is to increase knowledge of the possibilities to use natural regeneration of Scots pine and Norway spruce in the special conditions of northern Finland.

This project plan is compounded of four separate sub-projects: 1) Natural regeneration of Scots pine in northern Finland 2) Natural regeneration of Norway spruce dominated forests in northern Finland 3) Regeneration of forests in the protection forest area and in the high-elevated areas in northern Finland 4) Economic comparison of alternative forest regeneration chains in northern Finland.

The project utilizes the results and materials of earlier studies. New experiments and inventories are executed as well. The project will produce plenty of reviewed publications, the results of which serve practical forestry.

The aims of the study are to produce information about the methods based on the natural regeneration of forests in the conditions of the slow growing forests of low productivity.
