  1. 1. Volume and taper equations for Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L.) Karst.) and White spruce (Picea glauca (Moench) Voss) in Iceland

    Magister-uppsats, SLU/Dept. of Forest Resource Management

    Författare :Larus Heidarsson; [2014]
    Nyckelord :single-tree stem volume; stem diameter;

    Sammanfattning : The aim of this study was to evaluate different types of volume and taper equations that can be used to predict single-tree stem volume and stem diameter at any given height along the tree stem for plantation grown Sitka spruce (Picea sitchensis (Bong.) Carr.), Norway spruce (Picea abies (L. LÄS MER

  3. 2. Hur en ökad marktemperatur påverkar fotosyntes och markrespiration i en boreal skog

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hanna André; Agnes Bondesson; [2014]
    Nyckelord :klimatförändringar; växthuseffekten; boreal skog; fotosyntes; markrespiration; koldioxid; marktemperatur;

    Sammanfattning : During the year of 2008, a powerful earthquake hit the southern part of Iceland, which changed the geothermal conditions in the area around the city of Hveragerdi. Elevated soil temperatures in a nearby forest plantation have contributed to a unique opportunity for researchers to study how an increased soil temperature affects the boreal forest ecosystem, something that partly can be connected to the climate changes which are happening today.

  4. 3. Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Emil Bengtsson; Rasmus Nilsson; [2012]
    Nyckelord :produktionsjämförelse; Picea sitchensis; Picea abies; Halland;

    Sammanfattning : Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden.

  5. 4. Överlevnad, tillväxt och skador i planteringar av sitkagran (Picea sitchensis) efter stormen Gudrun

    Magister-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Erik Kristensen; [2011]
    Nyckelord :sitka ; gran; frost; svamp; skötsel;

    Sammanfattning : Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast. LÄS MER

  7. 5. En jämförelse av sitkagranens (Picea sitchensis) och den vanliga granens (P. abies) produktion

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Fredrik Tengberg; [2005]
    Nyckelord :Picea sitchensis; sitkagran; Picea abies; volymproduktion; odlingsegenskaper; ProdMod;

    Sammanfattning : Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. LÄS MER
