Assessment Of Floodplain Condition Across Puget Sound: An Emerging Tool For Tracking Investments And Communicating Status, Jennifer Burke, Colin Hume, Ilon Logan, Scott Mckinney
Salish Sea Ecosystem Conference
Floodplains are some of the most economically and ecologically vital lands of Puget Sound but also some of the most impaired as well. Investments at the local and regional level aim to improve aquatic and terrestrial habitat, reduce flood risk, and protect economically important lands. However, the condition and status of Puget Sound floodplains is poorly quantified in a consistent manner across the 17 major watersheds, hindering strategic investments and planning. The Puget Sound Partnership and Washington Department of Ecology are developing an assessment of floodplain condition and status for a Sound-wide watershed-scale floodplain monitoring effort using spatial data and …

Salish Sea Ecosystem Conference
The Nooksack-Fraser transboundary area (2639 km2) is home to communities with a strong base in farming, fisheries and outdoor recreation. Water quality issues impact parts of this area, where sewage effluent and animal waste are potential sources of both fecal coliform bacteria (FCB) and nitrogen (N) in the environment. Excessive nitrogen loading can lead to eutrophication in coastal areas, and nitrate contamination of groundwater. The Nooksack-Fraser Transboundary Nitrogen (NFT-N) project was developed to determine the sources and fates of N in the watershed using data on energy use, transportation, fertilization, wastewater treatment plants, livestock operations, wildlife and more. This project …

Salish Sea Ecosystem Conference
Rockfish are a long-lived species group that provide an important function for the food web dynamics in the Salish Sea, as both a mid-level trophic predator and important prey source, and they hold cultural significance to the region. Rockfish are comprised of over 25 different species locally, and over 60 species from California to Alaska. Many species experienced declines since the 1980’s, and two species are listed in the Salish Sea under ESA as threatened (yelloweye) or endangered (Bocaccio). Different species occupy a range of habitat types, from deep-water rock piles and hard bottom substrate, to nearshore kelp forests and …
A Framework For Incorporating The Toxicity Of Pesticide Mixtures Into Ecological Risk Assessments, Cathy Laetz, David Hugh Baldwin, Tony Hawkes, Scott A. Hecht, Nathaniel L. Scholz
A Framework For Incorporating The Toxicity Of Pesticide Mixtures Into Ecological Risk Assessments, Cathy Laetz, David Hugh Baldwin, Tony Hawkes, Scott A. Hecht, Nathaniel L. Scholz
Salish Sea Ecosystem Conference
Pesticides are widely used throughout the Puget Sound region and are frequently detected as complex mixtures in aquatic habitats. As a result, pesticide mixture toxicity is an important component of risk assessments performed within the Salish Sea region. Here we describe a process for assessing toxicity of three categories of pesticide mixtures; formulated products (one product containing multiple active ingredients), tank mixes (multiple pesticides applied simultaneously), and environmental mixtures (resulting from unrelated pesticide use over the landscape). Mixtures were assumed to be either dose-additive or response-additive, depending on the modes of action of the individual pesticide components. Toxicity estimates utilized …
