Priorities for 2018-2022 focus on accelerating progress toward the B-IBI target for the Freshwater Quality Vital Sign.
As an indicator of freshwater quality, the Benthic Index of Biotic Integrity uses invertebrates to measure stream health related to hydrologic conditions, water quality, and the associated impacts to habitat quality. This strategy is based on the work of the B-IBI Interdisciplinary Team (IDT), the group leading development of the B-IBI Implementation Strategy, who identified priority strategies to address the effects to stream health from the built environment and effects from the runoff of working lands, and strategies to protect heathy streams from the effects of new development. The Stormwater Strategic Initiative Advisory Team identified priorities from amongst the IDT-identified recovery strategies. Those recovery strategies represented the most important new work to advance recovery of freshwater resources from stormwater sources. The B-IBI Regional Priorities are not primarily focused on toxicity in freshwater systems, and while not always the case, stormwater treatment or loading reduction proposals may better fit the desired outcomes of Toxics in Fish strategies.
