Enhancing Community and Wildlife Resilience to Sea‐Level Rise and Infrastructure Development in the San Pablo Baylands
Project Overview: The San Pablo Baylands support critical wildlife habitat and major transportation infrastructure, but the combined effects of sea-level rise and planned highway redesigns on habitat and public access remain uncertain. Scientists supported by this Southwest CASC project will work with federal, state, and regional managers to fill key data gaps and model how sea-level...
Recreational Birdwatching and Habitat
Thousands of visitors flock to the Billy Frank Jr. Nisqually National Wildlife Refuge every year to look for birds both rare and common. Birdwatching activities contribute to economic activity for the Nisqually area and play a role in the broader outdoor-loving culture of the Pacific Northwest.
Fisheries and Fish Habitat
The estuarine habitat of the Delta is critical to the production of salmon, which supports recreational, commercial, and subsistence fishing. The combination of shaded pools, shallow reaches, and a rich prey population provide excellent feeding grounds for juvenile fish. Fishing also holds great importance in the cultural practices of the Nisqually Tribe.
Marsh Elevation Change and Carbon Sequestration
Tidal marsh vegetation grows in a narrow elevation zone between sea level and the upland behind it. These plant communities have evolved to accumulate sediment over time and maintain their relative elevation with gradual rates of change in sea level. It is uncertain which marsh vegetation communities will be able to accumulate sediment at a rate that keeps pace with accelerated sea level rise.
An Ecosystem Services Assessment of the Nisqually River Delta, South Puget Sound, Washington
Overview of Nisqually River Delta ecosystem services modeling
NASA-USGS National Blue Carbon Monitoring System
The NASA-USGS National Blue Carbon Monitoring System project will evaluate the relative uncertainty of iterative modeling approaches to estimate coastal wetland (marsh and mangrove) C stocks and fluxes based on changes in wetland distributions, using nationally available datasets (Landsat) and as well as finer scale satellite and field derived data in six sentinel sites.

Intertidal biofilm remote sensing paired spectra-biofilm training and validation data, South San Francisco Bay Intertidal biofilm remote sensing paired spectra-biofilm training and validation data, South San Francisco Bay
Intertidal microbial biofilms, or microphytobenthos, support estuarine biogeochemical cycling, the physical stability of mudflats, and food webs, particularly those of migratory shorebirds. Photosynthetic biofilms dominated by diatoms, cyanobacteria and chlorophytes represent a significant fraction of biofilm biomass and contain pigments that can be detected with remote sensing. These...
Water Level, Water Temperature, and Vegetation Biomass at the Nisqually River Delta, WA Water Level, Water Temperature, and Vegetation Biomass at the Nisqually River Delta, WA
This dataset contains water level, water temperature, and vegetation data from 12 locations within the Nisqually River Delta, Washington from 2010 to 2015. This dataset was part of a larger monitoring effort to document hydrological and vegetation changes throughout the Nisqually River Delta following large scale estuarine restoration (dike removal) in 2009.
Monitoring Changes in Surface Elevation Using Deep Surface Elevation Table and Marker Horizon Data at the Nisqually River Delta, Washington Monitoring Changes in Surface Elevation Using Deep Surface Elevation Table and Marker Horizon Data at the Nisqually River Delta, Washington
Surface Elevation Tables and Marker Horizon (collectively SET-MH) datasets provide a unique opportunity to evaluate tidal marsh accretion rates compared with current and projected sea-level rise. SET is a tool that allows for accurate and repeatable measurements of marsh elevation, while Marker Horizon allows for the measurement of sediment that has deposited on top of the feldspar...

Microbial biofilm communities are composed of fungi, bacteria, and phytoplankton taxonomic groups (e.g., cyanobacteria, diatoms, and chlorophytes), which inhabit the surface of intertidal mudflats. Such biofilms have critical roles in shorebird diets, mudflat stabilization, primary productivity, and carbon storage. These raster datasets represent the presence, nutritional quality...

Macroinvertebrate and environmental data were collected annually in July-August in the year before dike removal (2009) and the first three years after dike removal (2010-2012) at the Nisqually River Delta, Washington, U.S.A. Data were collected along a gradient extending from the inner marsh edge to the delta front and spanning different types of habitat including marsh restored to tidal

This dataset consists of carbon, nitrogen, and sulfur stable isotope data from primary producers, invertebrates, and fish from the Nisqually River Delta, Washington from 2011, 2012, and 2015. Data were collected to determine food web structure in different habitat zones within the entire river delta. Data collection for primary producers and invertebrates were led by U.S. Geological...

A comparison of eDNA sampling methods in an estuarine environment on presence of longfin smelt (Spirinchus thaleichthys) and fish community composition A comparison of eDNA sampling methods in an estuarine environment on presence of longfin smelt (Spirinchus thaleichthys) and fish community composition
The loss of tidal wetlands in the San Francisco Bay estuary have led to declines in native fish presence. Restoration of tidal wetlands in this area has intensified, with a primary goal of increasing the number of native fishes. We compared the presence of longfin smelt in naturally accreted and beneficial dredge reuse wetlands as a measure of successful restoration. We used...

Benthic macroinvertebrate response to estuarine emergent marsh restoration across a delta-wide environmental gradient Benthic macroinvertebrate response to estuarine emergent marsh restoration across a delta-wide environmental gradient
Benthic invertebrates play vital roles in estuarine ecosystems, but like other taxa they have been excluded from former marshlands by diking and land use conversion. Dike removal is one way of restoring marsh, but the response of benthic invertebrates has been little studied. Also understudied is variation in benthic invertebrate communities across entire deltas, particularly in the...

Allochthonous marsh subsidies enhances food web productivity in an estuary and its surrounding ecosystem mosaic Allochthonous marsh subsidies enhances food web productivity in an estuary and its surrounding ecosystem mosaic
Terrestrial organic matter is believed to play an important role in promoting resilient estuarine food webs, but the inherent interconnectivity of estuarine systems often obscures the origins and importance of these terrestrial inputs. To determine the relative contributions of terrestrial (allochthonous) and aquatic (autochthonous) organic matter to the estuarine food web, we analyzed...
