  1. 16. Glödbrandens effekter på trädrötter : ett modellförsök

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

    Author : Linda Bertholdsson; Sanna-Maja Breiman Wistbacka; [2018]
    Keywords : glödbrand; torv; rotpåverkan; fuktkvot; torrvikt;

    Abstract : Skogsbrand var tidigare ett allmänt inslag i de svenska skogarna och idag används elden i naturvårdsarbetet. För att förstå dess effekter på trädmortalitet har ett flertal studier genomförts där man har tittat på trädens försvar mot brand. READ MORE

  3. 17. Effects of climate warming on the performance of three boreal tree seedling species in interaction with moss cover and fire history

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Maria-Theresa Jessen; [2017]
    Keywords : ;

    Abstract : Forest regeneration in the form of successful seedling establishment is a key factor for the persistence of a healthy forest ecosystem. Tree seedlings grow in a complex environment shaped by over- and understory and competition for light, nutrients and water. READ MORE

  4. 18. The effects of burn severity on soil properties : Infiltration rate, moisture, grain size distribution and carbon content Hälleskogsbrännan as an example

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ola Haddad; [2016]
    Keywords : Hälleskogsbrännan; forest fire; burn severity; infiltration rate; soil moisture; loss on ignition.;

    Abstract : This study focuses on soil hydrological parameters that are expected to be related to burn severity in forests; infiltration rate, soil moisture, grain size distribution and carbon content along a burn severity gradient in Västmanland Sweden, where a major fire occurred in 2014. Hälleskogsbrännan was divided into two burn severities: a moderate severity and a high severity, and a control area. READ MORE

  5. 19. The Forest Fire in Västmanland, South Central Sweden, and its Effects on Soils and Forest Recovery

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sophia Sjödin; [2016]
    Keywords : Forest fires; soil bulk density; soil organic matter; pH; Skogsbrand; packningsgrad; organiskt material; pH;

    Abstract : Forest fires can have a great impact on the relationship between soil organic matter (SOM) and soilbulk density (SBD). SOM will reduce with increased fire intensity, which ultimately leads to more compaction of the soil. The compaction rate might increase to the limit of where root growth will be absent thus leading to actions to restore the soil. READ MORE

  6. 20. Plantetablering efter skogsbranden i Västmanland

    University essay from SLU/School for Forest Management

    Author : Karoline Åby Hedenius; [2016]
    Keywords : trädföryngring; brandintensitet; ekopark;

    Abstract : Fire has been a natural disturbance in boreal forests for a very long time. Species in the forest have evolved and adapted themselves to this disturbance. During the 1900th century big natural forest fires started to decrease because of human suppression and environments created by wildfire in the forest have now become rare. READ MORE
