Nagshead is a woodland reserve, located on the western edge of Parkend, in the Forest of Dean, Gloucestershire, and is home to RSPB Nagshead. The site is listed in the 'Forest of Dean Local Plan Review'.More than half of the reserve consists of 19th-century oak woodland, which is now managed solely for its conservation and landscape value.In 1942, nest boxes were erected, in the hope that pied flycatchers would control oak leafroller moth larva, which were defoliating trees.
