  2. Contents 1. Objectives 2. Sampling sites and protocols 3. Identification level 4. Relations between physical and biological components 5. Quality control (QA/QC)

  3. 1. Objectives • General ecology of the system • Assess water/habitat quality • Nature conservation (biodiversity)

  4. 2. Sampling sites and protocols 2.1. Protocols and standardisation 2.1.1. Training 2.1.2. Sampling 2.1.3. Sample processing 2.1.4. Identification 2.1.5. Database set up and maintenance

  5. 2. Sampling sites and protocols 2.2. Scale (spatial/temporal resolution) 2.2.1. Micro-habitats (size of sample) 2.2.2. Meso-habitats (morphological entities : riffles, pools, …) 2.2.3. Macro-habitats (river stretch) 2.2.4. Different identification level and additional measurements (shear stress)

  6. 2. Sampling sites and protocols 2.3. Sampling design stratified, randomised, … qualitative versus quantitative 2.4. Sampling methods Hand net, artificial substrates, … 2.5. Comparison of standard methods between different European countries

  7. 3. Identification level 3.1. Taxonomists (identification keys) 3.2. Identification costs

  8. 4. Relations between physical and biological components • Additional measurements (weather conditions, structural characteristics, special remarks, pollution sources, disturbing activities, …) • Habitat features • Link with other communities (macrophytes, algae, fish)

  9. 5. Quality control (QA/QC) 5.1. Training 5.2. Sampling 5.3. Sample processing 5.4. Identification 5.5. Database set up and maintenance
