Welcome to the Blackwater Conservation Group website.

In order to access a particular page, simply click on one of the tabs in the page heading.

The object of our group is to protect the landscape and ecology of the Blackwater Valley for future generations. We are a group of conservation volunteers concerned in particular about the environmental effects of water pollution and invasive species on the river Blackwater.

The Blackwater arises from several streams flowing down from the escarpment in the south east of the county of Wiltshire that separates the Avon Valley and Salisbury from the parishes in the extreme south east of the county. The river initially runs west to east before curving round to the south as it crosses into Hampshire and flows down to join the River Test near Totton. Unlike many of the chalk streams and rivers in Wiltshire that are alkaline, the Blackwater contains water from boggy woodland sources and as a consequence is acidic in nature.

Primary tasks carried out by the volunteers include chemical testing of river water for both Nitrates and Phosphates, sampling the river bed and identifying the invertebrates living there and the removal of Himalayan Balsam from the local environment.
