  1. 31. Naturvårdsbedömning i västra Värmland – Skillnaderna mellan målklasserna PG, NS och NO

    University essay from SLU/School for Forest Management

    Author : Marcus Thörnblom; [2020]
    Keywords : naturvärden; produktiv skogsmark; biologisk mångfald;

    Abstract : Den biologiska mångfalden är viktig i skogsbruket. Med skog som är avsatt för att gynna biologisk mångfald används målklasserna NO och NS som finns i skogsbruksplanen som markägare har. Genom Skogsbiologernas modell för naturvärdespoäng så kan man undersöka hur mycket naturvärden olika bestånd i skogen innehåller. READ MORE

  3. 32. 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

    Author : Josefin Runesson; [2019]
    Keywords : oil palm; carbon balance; carbon sequestration; land use change; soil carbon; carbon credits;

    Abstract : Considerable amounts of carbon (C) has been lost from tropical forests as a result of continuous conversion of tropical forests into oil palm plantations. Therefore, a better understanding of the C budget and potential sequestration rate in oil palm plantations and how it compares to natural forests is needed. READ MORE
