This is the third volume in a series of three appendices from the Hiz, Oughton and Purwell Environmental Appraisal, Final Report (December 1993). Information included covers general reference material on River Hiz; River Oughton and Oughtonhead Common; River Purwell. The essential objectives of this environmental appraisal were to catalogue the present day ecological, conservation and amenity value of the in river, riparian and associated wetland systems of the River Hiz, Oughton and Purwell, from their respective sources downstream to Cadwell Bridge, just north of Hitchin. These objectives were achieved through the combined processes of historical data review, consultation with interested bodies and considerable original baseline field survey work. The final report details the results of a 6 month study undertaken during April to September 1993, during which river corridor surveys and river landscape assessments were completed in accordance with standard NRA methodology, supplemented throughout with in stream community and channel morphology surveys.
