King County Ambient Monitoring Program Methods

The King County Freshwater Benthic Macroinvertebrate Sampling and Analysis Plan for annual monitoring.


Regional Puget Sound B-IBI Projects

King County staff have worked with partners in the region on projects related to benthic macroinvertebrates and stream health. Most of these projects were funded in part by WA Department of Ecology and EPA’s National Estuary Program. Links to more information about the projects are listed below.

The Restore and Protect Project 

King County has completed two projects related to the Puget Sound Partnership’s recovery and protection targets for B-IBI. 

The first project – Phase I - focused on developing a framework for identifying and prioritizing stream basins for restoration and protection, based in part on their B-IBI scores.

The second project – Phase II – focused on developing basin-specific restoration and protection plans for 14 Puget Sound basins.  

The Bug Seeding Project

This project aimed to jump-start the ecological recovery of several historically degraded King County streams by seeding them with a diverse community of macroinvertebrates – or “stream bugs” - from healthy streams.

The Recalibration of the Puget Lowlands B-IBI

King County worked with regional partners from 2010-2014 to enhance and standardize the Puget Lowlands benthic macroinvertebrate monitoring and analysis tools for the Puget Sound Region. This included updating and recalibrating the B-IBI scoring system, comparing field methods, and evaluating how environmental stressors affect macroinvertebrate communities.
