16、croinvertebrates shall be in accordance with IS0 5667-3, IS0 7828, IS0 8265 and IS0 9391. 6 Identification Sorting and identification of animals should follow the defined procedures appropriate to the indices to be used in the cassification. 7 Presentation procedure 7.1 Survey design For the purpose

17、s of presentation watercourses should be divided, as far as possible, into reaches such that within each reach the biological quality is consistent. Within each reach a sampling site should be selected that is representative of the reach as indicated by the benthic macroinvertebrate fauna. At this s

18、ite the observed data will be collected. 7.2 Classification A classification should be set up in accordance with the guidance given in IS0 8689-1. 7.3 Presentation Biological quality data should be presented in the form of a map showing the reaches surveyed, coloured according to the class of the re

19、presentative sampling site. The names of watercourses should be clearly marked on the map. The upstream and downstream limit of each reach should be shown on the map, together with the location of the representative sampling sites and an indication of the direction of flow. Colours and class descrip

20、tions used on the map should be in accordance with Table 1. 2 Q BSI 082000 STDmBSI BS EN IS0 8b89-2-ENGL 2000 = Lb24bb9 0883370 582 EN IS0 8689-22000 Colour Blue Green Yellow Table 1 - Colours and class descriptions Benthic macroinvertebrate quality classification High Good Moderate Orange Red Poor

22、w information to be presented on ail reaches surveyed, and show the whole study area, it is important that reaches that could not be surveyed are shown on the map.
