  1. 1. Saproxylic beetles in Populus tremula fauna depots - how do you construct the best depot?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Simon Selberg; [2019]
    Keywords : aspen; populus; tremula; saproxylic; beetle; fauna; depot; species; richness; abundance; diversity; cwd; course; woody; debris; forest; asp; populus; tremula; vedlevande; skalbagge; fauna; depå; art; mångfald; diversitet; död; ved; cwd; skog;

    Abstract : The biodiversity of saproxylic organisms and in the case of this study, saproxylic beetles, is dependent on the amount and quality of course woody debris (CWD) in the environment. Over the past decades the quantity of CWD in Swedish forests has increased, yet the quality has decreased, forests are managed and exploited, and old-growth forests are rarer. READ MORE

  2. 2. Utvärdering av Skogsbiologernas naturvärdesbedömning : en jämförelse mellan nyckelbiotoper och produktionsskogar

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

    Author : Michaela Lundberg; Martina Lundkvist; [2019]
    Keywords : biologisk mångfald; ; död ved; signalarter; rödlistade arter;

    Abstract : Det är viktigt att vi värnar om den biologiska mångfalden och nyckelbiotoper möjliggör att miljöer med höga naturvärden kan pekas ut. Ett sätt att bedöma naturvärden är att använda sig av indirekta kriterier, alltså leta efter strukturer som indikerar skyddsvärda arter. READ MORE

  3. 3. Clearcutting and the breeding productivity of golden eagles (Aquila chrysaetos) in Västerbotten County

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

    Author : Amanda Trulsson; [2019]
    Keywords : forestry; breeding productivity; breeding success; nestlings; breeding core home range; breeding core area;

    Abstract : The golden eagle (Aquila chrysaetos) is red-listed as near threatened in Sweden, but there are many basic ecological and demographical parameters important for successful management and conservation that are unknown for the Swedish golden eagle population. Forestry, and especially clearcutting (or final cutting/felling or regeneration cutting/felling), the most common harvesting system in Sweden since the 1950’s, are likely important factors affecting the Swedish golden eagle population, but exactly how is largely unknown.

  4. 4. Restaurering av grön infrastruktur för fyra naturskogsarter på Söderåsen i Skåne

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Johanna Schroeder; [2018]
    Keywords : entita; mindre hackspett; taggbock; bokblombock; GIS; habitatmodell;

    Abstract : Det intensiva brukandet av svenska skogar har inneburit att många arter missgynnats och hälften av landets rödlistade arter är knutna till skogslandskapet. Sverige har förbundit sig att bevara den biologiska mångfalden och ett verktyg i detta arbete är att jobba med grön infrastruktur. READ MORE

  5. 5. Planning for Viable Forests with High Biodiversity

    Abstract : In recent decades, the rate of extinction of species is increasing due to human use and refinement of nature. This has resulted in a large amount of research throughout the world. Forestry today is mostly based on clear cuts, and many natural forests have been cut down and replaced with monocultured forests. READ MORE
