Abstract

ABSTRACT: Capsule: Predation risk of artificial nests resembling Hazel Grouse Tetrastes bonasia nests was reduced in more diverse habitats and when roads and trails were closer. Aims: To determine the importance of habitat structure and the presence of roads and hiking trails for the predation risk of artificial ground nests. Methods: We investigated predation on artificial nests in mountain spruce forests with high tourist numbers in the Tatra Mountains, Southern Poland, in 2012–2014. Some 174 artificial ground nests resembling those of Hazel Grouse were set up and monitored. For 98 artificial nests, we compared environmental variables at two area scales, and the forest structure between predated and surviving nests. Results: At the local scale (within 5 m) artificial nests were more likely to be predated at sites with lower occurrence of ferns and lying dead wood. At the wider spatial scale (within 100 m), nests were more likely to survive if near to roads and tourist trails. The occurrence of different tree species in the forest stand did not significantly influence predation rate of artificial nests. The mean daily nest predation rate was not high and varied between years (0.003–0.009). Conclusion: Greater habitat diversity and the presence of roads and trails increased the survival of ground nests. These results are potentially important for conservation planning for threatened ground-nesting birds, such as the Tetraonidae.
