Site Description
UK ECN site. Dstl Porton Down is located in Southern England on the Wiltshire/Hampshire border. It is owned by Defence Science and Technology Laboratory (Dstl) and is used to deliver high-impact science and technology (S&T) for the UK's defence, security and prosperity. 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. 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). The ECN monitoring takes place at the heart of the ...

Vegetation
The site 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. As well as 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. The site also contains 20% of the Southern England juniper population, as well as 15 species of invertebrates endemic to Juniper.
