The moose is an important resource for Sweden but causes problems for forestry. Moose browsing damages annually cost forestry large amounts of money which makes it a hot topic of discussion. Another hot topic is biodiversity which has increased the interest of nature conservation burnings as the lack of natural fires in the northern boreal region affects biodiversity negatively. In this study, we examined diversity of tree species, moose browsing and feed availability in restoration burnings. The hypothesis was that the diversity, the absolute and relative browsing, the average width of browsed deciduous shoots and the feed supply would be higher in burned plots. The study was conducted in four areas in north-eastern Finland. Sample inventory was carried out 13 years after fire in form of a block design with 2-3 blocks each of fire and control for each area.
