- Abstract
- The survival of 86 clutches laid by hazel grouse Bonasa bonasia hens was studied using radio telemetry to evaluate the importance of key vegetation variables for nest survival between March 2003 and June 2009 in a 3000 ha study area of temperate forest in South Korea. The nest sites in the forest stands differed from that in the study area with dense understory cover and low visibility. Daily nest survival rates increased with understory cover, higher proportion of natural deciduous forest, and decreased with nest conspicuousness. Nest survival rates were not correlated with tree density, basal area, mid-story cover, and overstory cover. The results did not reveal any differences in the daily nest survival rate between first breeders and older hens. Habitat management that protects the remaining understory cover and natural deciduous forest is key to stabilizing threatened hazel grouse populations in temperate forests. (c) 2012 Elsevier B.V.
