Abstract:
Heavy natural disturbance in large protected areas of former commercial forests increasingly evokes<br/> European parliaments to call for management intervention because a loss of habitats and species is<br/> feared. In contrast, natural early successional habitats have recently been recognised as important for<br/> conservation. Current knowledge in this field mostly results from studies dealing only with selected<br/> taxa. Here we analyse the success of species across 24 lineages of three kingdoms in the Bavarian Forest<br/> National Park (Germany) after 15 years of a European spruce bark beetle (Ips typographus L.) outbreak<br/> that led to rapid canopy opening. Using indicator species analysis, we found 257 species with a significant<br/> preference for open forests and 149 species with a preference for closed forests, but only 82 species with<br/> a preference for the stand conditions transitional between open and closed forests. The large number<br/> of species with a preference for open forests across lineages supports the role of this bark beetle as<br/> a keystone species for a broad array of species. The slowdown of the outbreak after 15 years in the<br/> core zone of the national park resulted in less than half of the area being affected, due to variability in<br/> stand ages and tree species mixtures. Our case study is representative of the tree species composition<br/> and size of many large protected montane areas in Central European countries and illustrates that (1)<br/> natural disturbances increase biodiversity in formerly managed forests and (2) a montane protected area<br/> spanning 10,000 ha of low range mountains is likely sufficient to allow natural disturbances without a<br/> biased loss of closed-forest species.<br/>
