Title: Physical environment for river invertebrate communities
Author: National Rivers Authority
Document Type: Monograph
Abstract:
The first phase of the project, as the "River Welland Environmental Survey" aimed to provide objective information for conservation management of the River Welland, with particular regard to the habitats of aquatic macroinvertebrates. The study was of four main parts - 1. Catchment study - an overall assessment of existing biological data and the state of the river; 2. Non-macrophyte substrates - a quantitative study of major physical features and their associated macroinvertebrates; 3. Macrophyte survey - a general survey of the aquatic macrophytes of the catchment; 4. Habitat classification pilot study - a feasibility study with regard to determining a full list of aquatic macroinvertebrate habitats.
