  1. 11. Artificial gap creation and the saproxylic beetle community : the effect of substrate properties on abundance and species richness

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Nils Bodin; [2016]
    Keywords : boreal forest; nature conservation; saproxylic beetle; artificial gap creation; restoration measure; coarse woody debris;

    Abstract : Coarse dead wood (CWD) and gaps are structures that have become sparse in Swedish forests as a result of forestry. This is believed to be one factor contributing to diminishing biodiversity. Because of political undertakings to preserve biodiversity, Swedish agencies and forestry companies now aim to restore these and other structures. READ MORE

  3. 12. Regeneration establishment after conversion to multi-layered stands in Jämtland, central Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Simon Weise; [2016]
    Keywords : Norway spruce; recruitment; mortality; height increment; conversion thinning; multi-layered forest;

    Abstract : In 2010, different thinning treatments were applied in two Norway spruce (Picea abies) stands of 45 and 46 years in Jämtland, central Sweden. The goal of the main treatment was to achieve a high diameter variation with the long- term goal to develop a multi-layered stand. READ MORE

  4. 13. Abundance and diversity of small mammals in Swedish beaver systems

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Felicitas Glabischnig; [2015]
    Keywords : small mammals; beaver; Castor fiber; habitat heterogeneity; ecosystem engineer; biodiversity; bank vole; Myodes glareolus; wetlands;

    Abstract : Through their ecosystem engineering activities, beavers (Castor fiber ) create ponds and riparian zones littered with deadwood, providing hetero- geneous micro-habitats for a variety of small mammal species. In this study small mammals were snap-trapped in nine beaver systems and four reference wetland systems that were not created by beavers in southern and central Sweden to compare abundance and diversity of voles, shrews and mice.

  5. 14. Markberedning i blockrik terräng : en jämförelse mellan grävmaskin och harv

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Louise Magnusson; [2015]
    Keywords : död ved; lågor; naturhänsyn; planteringspunkter; skador; ytstrukturklass; dead wood; coarse woody debris; nature conservation; planting spots; damages; ground roughness class;

    Abstract : Runt 70 % av skogsföryngringen i Sverige utförs genom plantering efter maskinell markberedning. På de flesta marker uppnås tillräckligt antal godkända planteringspunkter men vid riklig förekomst av block som hindrar eller stör markberedningsaggregatet blir det problem. READ MORE

  6. 15. The secret role of elephants : mediators of habitat scale and within-habitat scale predation risk

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Ursa Flezar; [2014]
    Keywords : elephant impact; predation risk; coarse woody debris; immediate risk; Hluhluwe-iMfolozipark;

    Abstract : Elephants have long been recognized as important mediators of savannah vegetation structure. With their activities, like feeding on woody plants they may increase visibility of a habitat and produce coarse woody debris within that habitat. READ MORE
