  1. 11. Restoration strategies in boreal forests : prescribed burning and gap cutting effects on plant diversity and community composition

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Clara Espinosa Del Alba; [2020]
    Keywords : restoration ecology; boreal forest; fire; gap cutting; biodiversity; voluntary set-asides; vascular plants; bryophytes; forest management;

    Abstract : The boreal biome is one of the largest in the world and their forests have been widely exploited for centuries. Consequently, it has suffered ecological simplification and loss of biodiversity. Under these circumstances passive conservation is no longer enough and active restoration techniques need to be tested. READ MORE

  3. 12. Gallringens effekter på botten- och fältskikt i grandominerad produktionsskog : en studie av hur störning kan påverka β-diversitet i Norrland och Svealand

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : William Jaktén Langert; Andreas Widell; [2020]
    Keywords : biodiversitet; bottenskikt; fältskikt; störning; gallring; boreal skog;

    Abstract : Den boreala skogens beståndsstruktur har historiskt primärt präglats av brand, vilket skapat en flerskiktad beståndsstruktur. Störning är därför en avgörande faktor för artmångfald i dessa ekosystem. READ MORE

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

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

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

    Abstract : 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. READ MORE

  5. 14. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : David Kymmell; [2019]
    Keywords : landscape of fear; forest fire effects; herbivore prey; camera trapping;

    Abstract : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

  6. 15. Brandhårdhetens påverkan på knäckesjukans omfattning på brandfältet i Sala

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

    Author : Erik Sundström; [2018]
    Keywords : brandhårdhet; knäckesjuka; asp; Salabrännan; viltbete; fire severity; Pine twisting rust; aspen; the Sala fire; ungulate browsing;

    Abstract : Knäckesjuka (Melampsora pinitorqua) är en skoglig skadegörare som orsakar skador på ung tall (Pinus sylvestris). Svampen värdeväxlar mellan asp (Populus tremula) och tall för att fullborda sin livscykel. Tidigare studier visar en tydlig korrelation mellan hård brandhårdhet och kraftig lövetablering efter brand.
