  1. 1. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    University essay from SLU/Dept. of Ecology

    Author : Yixian Chen; [2023]
    Keywords : density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Abstract : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. READ MORE

  3. 2. Influence of structural complexity of the Rumperöd forest on evapotranspiration

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Madeleine Durdek; [2023]
    Keywords : Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

    Abstract : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. READ MORE

  4. 3. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Mathias Billenberg; [2023]
    Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

    Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE

  5. 4. Jämförelse av planteringsresultatet mellan markberedningsmetoderna harvspår och omvänd torva för planteringsmaskinen Plantma X

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Simon Dahlberg; [2023]
    Keywords : Maskinell plantering; terrängegenskap; planteringskvalitet; högläggning; blockkvot; stubbtäthet; humustjocklek;

    Abstract : Holmen har som första skogsbolag i Sverige köpt in planteringsmaskinen Plantma X med syfte att i framtiden ersätta delar av den manuella planteringen med maskinell plantering. Bra planteringskvalité samt en markberedningsmetod anpassad till traktens terrängegenskaper är viktiga faktorer för att planteringsmaskinen ska kunna implementeras i större skala framöver. READ MORE

  6. 5. Assessing tree modeling algorithm from terrestrial laser scanning in Rumperöd mixed forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stig Sand; [2023]
    Keywords : Terrestrial laser scanning; Hough transform algorithm; TreeLS; Rumperöd; Biology and Life Sciences;

    Abstract : Recent technological advancements have revolutionized tree inventory methods for the forest industry. The development of terrestrial laser scanning (TSL) and automatized tree recognition software to estimate crucial tree parameters such as diameter at breast height (DBH) has made the inventory work faster and more reliable.
