1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

2. Consequences of alternative forest management in riparian buffer zones : a GIS analysis
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

3. Beslutsstöd för att finna diken och bedöma behov av dikesrensning
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : En betydande areal torvtäckt mark dikades i Sverige under första halvan av 1900-talet i syfte att omvandla myrimpediment till produktiv skogsmark. Många av dikena hos markvärden för denna studie, Svenska Cellulosa AB (SCA), är nu i behov av rensning för att produktionen skall bibehållas. Rensning medför också allvarliga miljörisker. LÄS MER
4. Forest drainage effects on tree growth in Northern Sweden : developing guidelines for ditch network maintenance
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : At present, there are no clear guidelines for when and where ditch network maintenance (DNM) should be performed in Sweden. Recently there have been attempts to create tools that indicate the need for DNM, one of these tools is the Ditch Flow Tracker (DFT). LÄS MER
