However, deciduous forest only covers , barely more than 1.4% of the surface area of the park. Thus, the forest is principally coniferous forest, characteristic of the Scandinavian and Russian taiga ecoregion. This forest is mainly made up of Norway spruce (), but at the frontier with the barren zones, the main species is Scots pine (). Pines dominate because forest fires are less frequent than previously, since birch and Scots pine are the first species to return after a fire. It seems that fires occurred naturally over the ages, but there has not been a fire for two centuries, humans actively fighting against their propagation. The maximum age of the trees of the forest is 100 years, but certain pines have reached 500 years, being particularly inaccessible and thus spared by loggers. However, during the last 100 years, the forest has partially recovered the richness which characterizes old growth forests.
