Capercaillie (Tetrao urogallus) habitat characteristics in North-Boreal Finland.

摘要: This study aimed to identify tools for taking capercaillie habitats into consideration in forest management. would provide new alternatives ecologically more sustainable Capercaillie summer and winter locations, from wildlife monitoring counts (1998–2004) northern Finland, reference, non-capercaillie locations were combined with planning data, the area proportions of different landscape classes an 800-m radius circle surrounding reference compared. Thinning stands (in winter) spruce mires summer) abundant than landscapes, whereas e.g. seedling stands, mature waste land areas less abundant. The relative habitat use was highest mean tree diameter (DBH) 10.5 14.5 cm adult heath forests, peatland brood it peaked 18.5 cm. layer density positively associated use. A trend lower detected largest diameters (17–40 cm) comparison middle-sized (10–16 but not forests. Relatively young managed forests (age 30–40 years or more) can form suitable north-boreal However, this suitability is necessarily permanent. Understorey management, longer rotations multicohort management are because they increase available cover close ground, canopy cover, overall at scale bilberry cover.
