Structural complexity in managed and strictly protected mountain forests: effects on the habitat suitability for indicator bird species
Increasing the proportion of unmanaged forest in multi-functional forest landscapes is a central goal of international and national conservation strategies. However, the structural development in newly created forest reserves and its impact on forest species remain are controversially discussed, especially with regard to potential negative effects on light-demanding species in the first phase after reserve designation. We evaluated the effect of management cessation on habitat characteristics of four bird species indicative of different seral stages and structural components: Capercaillie (Tetrao urogallus), Hazel grouse (Bonasa bonasia), Three-toed woodpecker (Picoides tridactylus) and Pyg…
Outdoor recreation causes effective habitat reduction in Capercaillie Tetrao urogallus: a major threat for geographically restricted populations
Outdoor recreation inflicts a wide array of impacts on individual animals, many of them reflected in the avoidance of disturbed areas. The scale and spatial extent, however, at which wildlife populations are affected, are mostly unclear. Particularly in geographically isolated populations, where restricted habitat availability may preclude a relocation to undisturbed areas, effective habitat reduction may remain underestimated or even unnoticed, when animals stay in disturbed areas and only show small-scale responses. Based on telemetry data of 12 individuals, we investigated the spatial and seasonal effects of outdoor recreation, on western capercaillie Tetrao urogallus, considering two sc…
