Nest predation rates in managed and reserved extensive northern hardwood forests

摘要: Depredation rates on artificial ground and shrub nests in large blocks of managed remote reserved northern hardwood forests were studied the White Mountain National Forest (WMNF) (303 930 ha) New Hampshire, USA, from June to August 1991. Both types monitored by trip cameras that recorded depredations as eggs removed. No differences nest predation found for either or between forest blocks. Elevated are generally considered be indicative fragmented conditions; results this study suggest extensive England not even-aged silviculture with clearcut regeneration, which is commonly used manage hardwoods. All identified predators mammals.
