The Cornwall Wildlife Trust is a charitable organisation founded in 1962 that is concerned solely with Cornwall, England, United Kingdom. It deals with the conservation and preservation of Cornwall's wildlife, geology and habitats managing over 50 nature reserves covering approximately 4300 acre, amongst them Looe Island. Cornwall Wildlife Trust is part of The Wildlife Trusts partnership of 46 wildlife trusts in the United Kingdom. It works in conjunction with the Isles of Scilly Wildlife Trust on some matters. Cornwall Wildlife Trust produces a thrice-yearly magazine called Wild Cornwall. The direction and work that the Trust currently does is guided by the Cornwall Biodiversity action plan. Living Seas and Living Landscapes are two such projects. The Trust runs ERCCIS (Environmental Records Centre for Cornwall and the Isles of Scilly), a county wide database of sightings of animals and plants, and records of geology. It also gives planning advice (CEC - Cornwall Environmental Consultants) to land developers. The Trust is based at Allet near Truro in Cornwall. The headquarters and offices are adjacent to the Trust's Five Acres nature reserve. This reserve includes two ponds, as well as mixed broadleaved and conifer woodland.
