Title: Biological survey report - Chess catchment, June-Oct 1992
Author: Dave Leeming
Document Type: Monograph
This report presents the results of a detailed biological survey of the River Chess catchment. The Chess valley is an attractive rural landscape and the chalk streams it contains are highly valued for the biological resources they support. There are 22.5 km of watercourse in this catchment. The broad aims of the catchment survey described in this report are: (1) Identify polluting influences and spatial changes in water quality; (2) Review past changes in biological status; (3) Provide a baseline of biological information for the catchment. This information can be used to assess any future changes in water quality or ecosystem status, either for the purposes of routine monitoring or for special surveys in connection with pollution incidents or other environmental problems; (4) Assess the quality of habitat and channel features. Identify sections of watercourse with importance for nature conservation, or requiring enhancement/reinstatement. Identify locations of any outstanding macroinvertebrate assemblages for consideration as special ecosystems.
