Alternatives to clear-cut forestry: effects on biodiversity, carbon sequestration, and other non-timber services

Sustainable production of forest resources is central to the development of sustainable energy systems. Increased use of clear-cut-free methods is often suggested as a path towards greater sustainability. However, this claim lacks empirical support. The goal of the project is therefore to identify and quantify potential differences in the effects on biodiversity and ecosystem services between clear-cut-free methods and clearcut forestry.

We will evaluate the effects of gapcutting and shelterwood as alternatives to clearcut forestry in a large nationwide experiment. We measure the effects on biodiversity (insects, plants, and soil fungi) and on ecosystem services such as berry production, winter forage for reindeer, and forest carbon fluxes (soil respiration and tree growth).

The effects are evaluated in both upland pine and spruce forests and pine forests on peatland. The results will provide a knowledge base and decision support for industry, government agencies, and civil society.
