  1. 26. 250 years of disturbance dynamics in a pristine old-growth Picea abies forest in Arkhangelsk region, north-western Russia : a dendrochronological reconstruction

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Tatiana Khakimulina; [2011]
    Keywords : Forest history; disturbance dynamics; canopy gap; old-growth forest;

    Abstract : To describe the historical patterns of natural disturbance regimes in European borealforests we conducted a dendroecological study in a primeval old-growth sprucedominated stands and reconstructed the long-term dynamics of canopy disturbances.We treated the radial growth releases of individual sub-canopy trees as the majorindicator of sudden openings in the forest canopy.

  3. 27. Mortality dynamics in an old-growth stand of beech (Fagus sylvatica) in Southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Mauricio Ivan Fuentes Perivancich; [2010]
    Keywords : beech; Southern Sweden; mortality dynamics;

    Abstract : Mortality patterns were assessed in an old growth beech stand in southern Sweden. Aprevious inventory of 1200 trees in 1996 was used as a base for an inventory in 2006.Mann-Whitney U test was used to compare statistical distribution between living anddead trees of those inventoried in 2006.

  4. 28. Analys av individinriktad ekskogsskötsel i Blekinge : en metod för tillämpning i ett kontinuitetsskogsbruk?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Olle Sjölin; [2009]
    Keywords : ek; quercus robur; enskilda träd; frihuggning; diametertillväxt; kontinuitetsskogsbruk;

    Abstract : Ett ökat brukande av skog enligt skötselprinciper som leder till skiktade beståndsstrukturer, en blandad trädslagssammansättning och kontinuerligt skogbeklädd mark har potential att öka den biologiska mångfalden och värdet för rekreation (Emborg m.fl. 2000, Berg m.fl. READ MORE

  5. 29. Tillväxt och potentiell sågtimmerkvalitet i gallringsmogna jämförelseplanteringar med Pinus contorta och P. sylvestris

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

    Author : Cecilia Persson; [2008]
    Keywords : Pinus contorta; Pinus sylvestris; jämförelse; produktion; kvalitet;

    Abstract : The Swedish Cellulosa Companiy, SCA, has today 280 000 ha planted with lodgepole pine (Pinus contorta var. latifolia) ("C") which is equivalent to 14 % of its total forest area. Exotic lodgepole pine has in previous experimental stands shown a superior growth than the native Scots pine (Pinus sylvestris L.) ("S"). READ MORE

  6. 30. Models of individual tree mortality for trembling aspen, lodgepole pine, hybrid spruce and subalpine fir in northwestern British Columbia

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

    Author : Sören Möller Pedersen; [2007]
    Keywords : tree mortality; density dependent mortality; statistical models; SORTIE-ND; British Columbia; sub-boreal spruce zone;

    Abstract : Density dependent mortality is an important process in forest succession. The overall predictive abilities of forest simulation models are closely related to their ability to predict mortality. Finding appropriate methods for modelling mortality have often proved to be a difficult challenge. READ MORE
