    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Robert Pim; [2023]
    Keywords : tree regeneration; tree establishment; wildfire; boreal forests; disturbance; sapling regeneration; generalized linear mixed models;

    Abstract : The factors affecting tree establishment in boreal forests after fire will help determine the community composition of the regenerating forest. These may have large consequences on the community dynamics for years after the fire disturbance. READ MORE

  5. 4. The Combined Influences of Canopy Openness, Browsing Protection, and Low Intensity Fire on the Natural Regeneration of Oak in Southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Benjamin Miles; [2022]
    Keywords : burn; browsing; disturbance; fire; light; oak; Q.robur; Q.petraea; ungulates;

    Abstract : Whilst oak was historically prevalent in the landscape of temperate Europe, changes in the disturbance regime of forests have led to limited regeneration across its distribution. In this study, the fire oak hypothesis is tested to assess the tolerance of Quercus robur and Quercus petraea recruits (seedlings and saplings) to a low intensity burn, and how this response may differ depending on the presence of browsing and canopy openness.
