FOCUS ON STANDARD INVERTEBRATE DATA

COLLECTION THAT IS USED FOR RIVER

WATER BODY STATUS CLASSIFICATION

Chapter 2 focuses on standard invertebrate data collection that is used for river water body status
classification. It provides detailed information on methods for field and laboratory work. This includes
sampling, laboratory assessment and enumeration methods, field data collection and storage.

It broadly follows the monitoring cycle below, focusing on the elements circled in red:
