  1. 1. Differences and similarities in stand characteristics after prescribed burning and wildfire : implications for conservation of forest biodiversity

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Hannah Sophie Jakob; [2023]
    Nyckelord :coarse woody debris; conservation; biodiversity; boreal forest; Daldinia loculata; Fennoscandia; prescribed burning; regeneration; wildfire; woodpecker;

    Sammanfattning : 1. Wildfires are a natural disturbance in the boreal forests of Fennoscandia and have shaped and formed forests in the past, resulting in very heterogeneous forests containing large amounts of dead and living trees in various age classes. LÄS MER

  3. 2. Influence of forest mires on wildfire : a landscape analysis of the 2014 Västmanland forest fire

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

    Författare :Andreas Souropetsis; [2022]
    Nyckelord :Forest fire; Mires fuel composition; Aerial photo interpretation;

    Sammanfattning : Forest fire is a major natural disturbance that influence forest ecosystem structure and composition at both the stand and landscape level. In boreal Fennoscandia fire frequency has been very low over the last c.150 years due to effective fire suppression, although occasionally high-intensity fires escape initial attack and grow big.

  4. 3. Prescribed burning in Sweden : an evaluation of structural outcomes from restoration oriented prescribed burns

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Virginia Hermanson; [2020]
    Nyckelord :prescribed burning; restoration; boreal forest; biodiversity burning; dead wood;

    Sammanfattning : The application of prescribed burning as a conservation measure is a growing trend in Fennoscandia to restore forest landscapes that have been heavily impacted by humans. Both intensive management for forestry and wildfire suppression altered the disturbances shaping boreal forests over the past centuries, which seen today are more homogenous, lacking dead wood and deciduous trees, and are in the successional process towards darker Picea abies (Norway spruce) dominated stands.

  5. 4. Community structure of polyporous fungi after wildfire in boreal forest

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Isak Vahlström; [2019]
    Nyckelord :biodiversity; community composition; natural disturbance; forest fire; polyporous fungi; ; wood-decaying fungi;

    Sammanfattning : Wildfire is a natural disturbance that creates large amounts dead wood and contribute to a landscape of different successional stages, important for biodiversity. The number of wildfires have declined in boreal Fennoscandia due to effective fire suppression. LÄS MER

  7. 5. Comparison of forest fire suppression in Quebec and Sweden : a historical review, 1998-2015

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Maryjane Heckel; [2018]
    Nyckelord :boreal wildfire suppression; firefighting resource; deployment; effectiveness; aircraft; personnel; area burned; cost; efficiency; response time; remoteness; Sweden; Quebec;

    Sammanfattning : This study compared two suppression systems in Quebec and Sweden: a centralized wildfire agency working with remote fires in Quebec, and a decentralized fire suppression system in Sweden, with each municipality responsible for extinguishing fires in their community. Their management approaches reflect differences in population density and land area. LÄS MER
