Cramer Fish Sciences propose to develop a consistent and comprehensive spatial database of tidal barrier features (e.g., culverts, tide gates, levees, and dikes), and current and potential tidal wetland habitat extents for Puget Sound’s major large river deltas. Although numerous spatial datasets for tidal barrier and wetland habitat currently exist, these have not been synthesized into a consistent regional dataset. In addition, many datasets are incomplete or have become outdated. We will compile regional datasets into a consistent spatial database and use remote sensing to update and correct regional data, digitize missing features, and classify feature types and potential connectivity impacts. The resulting spatial database will be used to delineate current and potential tidal wetland habitat extents that integrate tidal barrier information developed in this proposal. The products of this project will directly support and leverage salmon recovery planning and evaluation in the Puget Sound region (e.g., ESRP’s River Deltas Learning Objectives, PSP’s Estuaries Vital Sign and Common Chinook Indicators, NOAA’s Salmon Habitat Status and Trends Monitoring Program, and WDFW’s intertidal fish passage assessments) by providing spatial data that can be used to identify and evaluate restoration opportunities, inform development and evaluation of recovery targets at regional and system scales, and identify data gaps to guide future research needs..
