Abstract

Article history: Low-intensity livestock grazing is a widespread management tool in order to maintain habitat diversity Received 27 January 2017 in mountain pasture-woodlands for nature conservation purposes. Historical photographs indicate that Received in revised form 9 June 2017 forest disturbance significantly contributed to forest-grassland mosaic pattern formation. Disturbance- Accepted 12 June 2017 grazer interactions are however poorly understood and the effects of logging or windthrow are rarely considered in management plans. Moreover, disturbance-grazer interactions are crucial for the mainte- Keywords: nance of open habitats in the upcoming “rewilding” approach of nature conservation. Semi-open landscape We aimed to understand the effects of forest gap creation by the breakdown of senile trees or by Forest-grassland mosaic single-tree cutting and of large forest openings by windthrow or logging on mosaic pattern formation in Segregation pasture-woodlands that were grazed by cattle and dominated by tree species with distinct regeneration Management ecology (Picea abies vs. Fagus sylvatica).

We simulated disturbance and grazing scenarios in an artificial mountain landscape and analyzed mosaic patterns with landscape metrics. We found that grazing in absence of disturbance promoted simply
