  1. 1. Odlingsförsök med Pinus sylvestris i gransågspån blandat med hydrokol respektive pyrokol

    University essay from SLU/School for Forest Management

    Author : Annica Berglund; Ninja Bernzen; [2023]
    Keywords : alternativt odlingssubstrat; näringsläckage; biokol;

    Abstract : Torv är det vanligaste odlingssubstratet som används idag till de mer än 400 miljoner skogsplantor som årligen levereras till det svenska skogsbruket. Det låga näringsinnehållet och goda vattenhållande förmågan gör att torven går att anpassa efter behov med gödsling och kalkning. READ MORE

  3. 2. Increasing forest mortality and its drivers: Simulating central European forests under climate change

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Marieke Scheel; [2021]
    Keywords : forest mortality; central Europe; competition; CO2; temperature; precipitation; DVM; LPJ-GUESS; simulation; reproducing data; Earth and Environmental Sciences;

    Abstract : Increasing tree growth and mortality rates in Europe are still poorly understood and have been attributed to a variety of drivers. This study aimed to relate increasing forest mortality rates in six central European countries to climate drivers (CO2 concentration, temperature and precipitation) from 1985-2015, using a process-based vegetation model.

  4. 3. Modelling nitrogen balance in two Southern Swedish spruce plantations

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johannes Loer; [2016]
    Keywords : maximum bearable nitrogen input rate; atmospheric deposition; nitrogen saturation; forest fertilisation; ForSAFE; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Emissions from agriculture and the combustion of fossil fuels increase the atmospheric load of reactive nitrogen (N). N deposition is projected to continue posing significant harm both for environmental and human health over the upcoming decades. Eutrophication as a result of N leaching is one of the negative effects of heavy deposition. READ MORE

  5. 4. Skogabyprojektet : en analys av skogliga tillväxtdata 1987-2001

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

    Author : Helene Larsson; [2015]
    Keywords : torka; försurning; näringstillförsel; bevattning; gran; skogsekologi;

    Abstract : En rad olika faktorer påverkar skogens tillväxt. I denna studie undersöktes hur försurning, samt vatten- och näringstillgång påverkar tillväxten. Materialet kommer från Skogabyförsökets mätningar för åren 1987-2002 under vilka mätningar skett 1987, 1993 samt vintern 2001-2002. READ MORE

  6. 5. Lichen decline in areas with increased nitrogen deposition might be explained by parasitic fungi : A survey of parasitic fungi on the lichen Alectoria sarmentosa after 4 years of nitrogen fertilisation

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Caspar Ström; [2011]
    Keywords : parasitic fungi; lichen diversity; Alectoria sarmentosa; nitrogen deposition;

    Abstract : Nitrogen (N) deposition in Europe has recently increased and is expected to continue to increase in the future. There is a well-documented decline in lichen diversity with higher N availability, although the mechanisms behind this are poorly known. In this study, I tested whether attacks by fungal parasites increase with higher N deposition. READ MORE
