1. Old-Growth Forests in the High Coast Region in Sweden and Active Management in Forest Set-Asides
Sammanfattning : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. LÄS MER
2. Colonization Patterns of Wood-inhabiting Fungi in Boreal Forest
Sammanfattning : Forest management practices have changed the over-all structure of the Fennoscandian forest landscape resulting in a lack of suitable substrates for many wood-inhabiting species. The objectives of this thesis was to describe the colonization patterns of wood-inhabiting fungi, including the potential role of beetles as dispersal vectors, on different types of dead wood substrate and assess the importance of active measures in the forest landscape in order to restore biodiversity i.

3. Habitat requirements of saproxylic beetles on aspen : implications for preservation
Sammanfattning : .... LÄS MER
4. Spatiotemporal monitoring of rare and elusive saproxylic beetles - A pheromone based approach
Sammanfattning : Forest ecosystems are under severe pressure from global environmental changes and increasing demands of wood-related products. During the last century, intensified management regimes have led to the decline of many previously common forest habitats, with catastrophic effects for biodiversity. LÄS MER
5. Long and short term effects of stump harvesting on saproxylic beetles and ground flora
Sammanfattning : Research on the effects from forest management on biodiversity has been going on for decades but still there are many questions unanswered. With every introduction of a new forestry method there is risk for increased pressure on biodiversity. The harvesting of low stumps left after final harvesting is a relatively new method used in forestry. LÄS MER
