review of conceptual landscape planning models for multiobjective forestry in Sweden

This paper reviews the approaches to multiple objective landscape planning that have developed in Swedish forestry in the 1990s. The objectives of such planning include primarily timber production and maintenance of biodiversity, but also aspects such as aesthetics and recreation. The variety of approaches and models that have emerged is caused by regional differences in land-use history, forest conditions, recreation pressure, and ownership. We distinguish three approaches: The species approach and the naturalness approach integrate conservation aspects, while the multiple aspects approach integrates several aspects (biological, social, economic, spiritual, etc.) into commercial timber-producing forestry. The species approach is exemplified by the key habitat - corridor model in which key habitats and corridors are preserved to support certain species. The natural landscape model illustrates an example of the naturalness approach, as it integrates natural forest features from a fire-disturbed landscape and gives examples of management implications at the landscape as well as at the stand level. The multiple aspects approach combines several objectives and defines important structures rather loosely. This approach was developed in areas where private nonindustrial forestry dominates. Nontimber and nonconservation aspects therefore become relevant to forest management. The supportive feature model exemplifies an application of that approach.
