| Description | Marine benthic invertebrates (benthos) are key components of the Puget Sound ecosystem, with many species providing important services such as nutrient renewal, food for other species (including human consumption), and ecosystem engineering. Benthos are valuable sentinels of ecosystem health because of their direct association living in, and sometimes consuming, sediments. Indicators of benthic invertebrate community health can serve as direct measures of sediment and water quality. These can help to answer key questions such as: • What is the current condition of the benthic habitat, including sediments and porewater and their associated invertebrate assemblages? • How does benthic condition change over time in response to natural and human disturbances, especially as climate change modifies the ecosystem? However, no widely accepted benthic infaunal indices equivalent to those developed elsewhere have yet been adopted for sediment regulatory or ambient monitoring work in Puget Sound. As part of the June 2020 revision of the Puget Sound Vital Signs, the Puget Sound Partnership adopted an as-yet-unspecified Marine Benthic Index as an indicator of the Marine Water Vital Sign to fill a recognized gap in indicators of Puget Sound health. This project will develop not only the Marine Benthic Index to assess and communicate status and trends of benthic invertebrate community health, but also a graphical causal model that will be used to estimate linkages and test hypotheses of causation. |
