  4. 2. Long and short term effects of stump harvesting on saproxylic beetles and ground flora

    Author : Jon Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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. READ MORE

  5. 3. Boreal vegetation responses to forestry as reflected in field trial and survey data

    Author : Johan Bergstedt; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Logging; boreal forest; selective cutting; scarification; ground-layer flora; survey data;

    Abstract : This thesis had two objectives: the first objective was to evaluate the response of forest ground vegetation to selected forestry operations, i.e. cutting of different intensities and scarification; the second objective was to compare the use of survey data in vegetation research with that of more traditional research using field trials - i.e. READ MORE

  6. 4. Heathlands – A Lost World?

    Author : Mattias Lindholm; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heathland; Calluna vulgaris; Conservation biology; Management; Coleoptera; Carabidae; Lycosidae; Conservation strategy;

    Abstract : Heathland is a familiar landscape type in southwest Sweden. It is open with few trees, and the vegetation is dominated by dwarf-shrubs growing on nutrient-poor soils. Dry heaths with Heather Calluna vulgaris and wet heaths with Bell Heather Erica tetralix are common vegetation communities in the heathland, and they often form mosaics. READ MORE

  7. 5. Boreal vegetation responses to forestry as reflected in field trial and survey data and the quality of cover estimates and presence/absence in vegetation inventory
