  1. 1. Evaluation of the forest composition in browsed Scots pine plantations

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Carl Noyce; [2022]
    Keywords : browsing damage; forest owners; mera tall; moose; pine regeneration; Södra;

    Abstract : Since the early 2000s browsing damage to Scots pine (Pinus Sylvestris) in the Götaland region of Sweden has been consistently estimated to be 15% per year, peaking at around 25% between 2009-2016, the highest of any region in the country. The Swedish Forest Agency has set a goal of achieving pine damage levels below 5% on average in the long-term, even if higher levels can be accepted in an individual year. READ MORE

  6. 5. Evaluated density estimates of young forest stands using high resolution 2D imagery from UAV

    University essay from SLU/Dept. of Forest Resource Management

    Author : Victor Kingstad; [2020]
    Keywords : UAV; forestry; inventory; survey; cleaning; tending; PCT; pre com-mercial thinning;

    Abstract : After more than three decades of advanced technology and methods to evaluate young forest attributes, the forestry still prefers laborious field surveys in regenera-tion forests. Preceding studies have virtually all successfully identified the saplings, but the cost has outweighed the benefits or at least not yet convinced the companies to step away from the traditional field surveys; high-resolution photogrammetric point clouds and ALS-data can provide accurate estimations of the biophysical prop-erties but requires intense data processing.
