The Rapid Bioassessment Protocols were originally developed in the 1980's to provide cost-effective, efficient biological survey techniques. They have since been revised and were reissued in 1999. The concepts underlying the RBPs are:
  • Cost-effective, scientifically valid procedures for biological surveys,
  • Provisions for multiple site investigations in a field season,
  • Quick turn-around of results for management decisions, and
  • Scientific reports easily translated to management and the public.

The RBPs were synthesized from existing bioassessment methods used by several state water resource agencies. The protocols are appropriate as tools for:

Forty-three states currently use bioassessments in non-regulatory water resource management. Once the framework for bioassessment is established, biological monitoring can be easily and rather inexpensively performed using the RBPs.
