General Site Description: 

UK ECN site. Porton Down is located in Southern England on the Wiltshire/Hampshire border. It is owned by Defence Science and Technology Laboratory (Dstl) and is a military research area. It has been closed to the public for over 100 years, resulting in it missing out on the agricultural revolution which affected the rest of the country. This is why it constitutes the largest uninterrupted tract of semi-natural chalk grassland in Britain, a habitat which has declined by more than 80% in the last 50 years. Over 1500 hectares is designated as a Site of Special Scientific Interest (SSSI), a Special Area of Conservation (SAC) and a Special Protection Area (SPA). In addition to the grassland the site supports large areas of mixed scrub, including juniper, and broadleaved, mixed and coniferous woodland. These habitats contain many rare and characteristic plants. Porton Down also contains 20% of the Southern England juniper population as well as 15 species of invertebrates endemic to Juniper. It is also one of the best butterfly sites in the UK with 44 species being recorded. The ECN monitoring takes place at the heart of the site on the chalk downland and takes in some of the sites special features. The ECN protocols that are undertaken on Porton Down include Atmospheric chemistry, Precipitation chemistry and Weather data. Ecological data includes Rabbits, Birds, Butterflies, Moths, Ground Predators and Spiders.
