The County Avifauna series provides detailed information on the range and status of bird species at county level. Each title includes a breakdown of rarity records, and there are introductory sections describing the area's ecology, climate, ornithological history and conservation record, as well as a gazeteer of the best sites to visit.
Gwent contains a wide range of habitats in a relatively small area, including estuarine wetland in the south, valleys in the west, and uplands in the north, with heavily wooded areas in the Usk and Wye valleys. Major sites include the Newport Wetlands, which attracts visitors from throughout Wales and the west of England to its wet grassland, saline lagoons and freshwater reedbeds. Other important sites include Peterstone Wentlooge (along the Severn Estuary west of Newport) and Llandegfedd Reservoir.
