  1. 1. Implementation of Scheimpflug Lidar for Entomological Monitoring of Bark Beetles

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Jonathan Peterson; [2020]
    Keywords : Scheimpflug Lidar; Lidar; Bark beetles; Forestry; Entomological monitoring; Physics and Astronomy;

    Abstract : Bark beetles are responsible for great damages to Swedish forestry every year. This project focuses on a method of entomological lidar called Scheimpflug lidar to detect and monitor bark beetles. Scheimpflug lidar uses old techniques from photography to achieve a deep field of focus to resolve objects over long distances. READ MORE

  2. 2. Evaluated density estimates of young forest stands using high resolution 2D imagery from UAV

    University essay from SLU/Dept. of Forest Resource Management

    Author : Victor Kingstad; [2020]
    Keywords : UAV; forestry; inventory; survey; cleaning; tending; PCT; pre com-mercial thinning;

    Abstract : After more than three decades of advanced technology and methods to evaluate young forest attributes, the forestry still prefers laborious field surveys in regenera-tion forests. Preceding studies have virtually all successfully identified the saplings, but the cost has outweighed the benefits or at least not yet convinced the companies to step away from the traditional field surveys; high-resolution photogrammetric point clouds and ALS-data can provide accurate estimations of the biophysical prop-erties but requires intense data processing.

  3. 3. Lavspridning på hyggesbrända hyggen

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

    Author : David Persson; [2020]
    Keywords : artificiell; lavspridning; hygge; ren; renskötsel; renbete; hyggesbränning;

    Abstract : Den boreala skogen har under mycket lång tid präglats utav bränder. Innan människan började kontrollera skogsbränder var det en naturligt återkommande störning. Idag bekämpas och kontrolleras naturliga skogsbränder av människan för att skydda timmer i skogarna. READ MORE

  4. 4. Tidig höjdutveckling av lignoser i landskapsplanteringar : en jämförande studie av Vindarnas Park i Lund och landskapslaboratorierna i Alnarp och Snogeholm

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Author : Christoffer Andersson; [2020]
    Keywords : landskapsplanering; landskapslaboratorium; tidig höjdutveckling; etablering; medeltillväxt; Vindarnas Park; Alnarp; Snogeholm;

    Abstract : En viktig aspekt för att kunna arbeta med vegetation är att förstå dess utveckling över tid. Att kunna förutspå tidig höjdutveckling i landskapsplanteringar är särskilt viktigt genom att det är avgörande för att skapa interiör och volym. READ MORE

  5. 5. The effect of Arbuscular mycorrhizal fungi and biostimulating algae extract on establishment, growth and development of Vitis vinifera : a field study conducted in Sweden

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Hanna Silwer; [2020]
    Keywords : Arbuscular mycorrhiza; biostimulator; crop physiology; mineral fertilizers; precision farming; Vitis vinifera;

    Abstract : About 23% of total global net anthropogenic emissions of greenhouse gases (GHG) come from agricultural and forestry related activities. One of the largest contributors of GHG is the usage of nitrogen (N) and phosphorous (P) fertilizers, causing eutrophication and contributing to global warming. READ MORE
