Forests are a renewable resource, but still deforestation can occur even in the most forested areas. Deforestation cause emissions of carbon dioxide and a loss of ecosystem services. With reforestation a new forest can compensate for the emissions and it shows that a sustainable forestry can favor both this generation and future generations. Investment costs in the forest may seem big for this generation when future generations will get the benefit. In Sweden this is controlled by a law of silviculture (1979:429) and in this study the focus ends up on the obligation to reforest. Through interviews with forest owners of different sizes and compositions their valuation of the forest and forestry has been enthroned through 5 perspectives. In these we can se how they relate to these investment problems and what drives them in keeping the forestry sustainable. Here we can se that forest owners experience reforestation as a natural part of forestry but that other problems between yield and sustainability can occur. Trade-offs between detailed conservation and high production is an example.
