| Abstract: | Health status of trees was studied in five types of native spruce forests in the Pechora-Ilych Nature Biosphere Reserve. The study has shown that trees in the old-growth bilberry-spruce and fern-shamrock-spruce forests can be characterized as “healthy”, with damage index varying from 0.03 to 0.5. The haircap-moss spruce forest with damage index 0.7 is categorized as a “weakened stand”. Regeneration was pronounced in all forest types. Young growth (1500 to 4300 stems/ha) is mainly composed of conifers and is classified as “healthy”. |
