Title: Biological survey report - Pymmes Brook and Salmon Brook catchment
Author: Dave Leeming
Document Type: Monograph
Annotation: EA additional title info: June 1992
Abstract:
This report presents the results of a detailed biological survey of the Pyrames Brook, Salmon Brook and their tributaries. 71 km of watercourse are contained in this catchment, including a mix of rural, green belt locations and more extensive urbanised areas of North London. 28 sites were visited for single season macroinvertebrate sampling during midlate June 1992. The broad aims of the catchment survey described in this report are: (1) Identify polluting influences and spatial changes in water quality; (2) 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; (3) 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.
