For some benthic macroinvertebrates it is necessary to undertake more targeted sampling using different methods of collection, because the OSAP methodology does not adequately survey their habitat type. Benthic macroinvertebrates (BMI) are a useful indicator of stream health. BMI are relatively quick, inexpensive, and can indicate the presence (or absence) of pollutants in a water body. They have predictable community composition under natural conditions and provide a snapshot of long term conditions. Some BMI are especially useful for targeted sampling due to their high sensitivity to environmental changes and pollutants. france mobile number code Macroinvertebrate sampling requires little equipment, with methods depending on the waterbody being sampled.
