This data set contains genetic information collected from eelgrass (Zostera marina) populations along the Pacific coast of North America from Alaska to Baha California. A total of 447 samples were collected comprising 401 unique individuals (genets) and 46 clones (ramets) from which 10 microsatellite DNA loci were obtained.
USDA-ARS researchers have put together high resolution ARC-GIS layers for intertidal bathymetry and distance to mouth as well as eelgrass, burrowing shrimp and oyster aquaculture habitats in Willapa Bay, Washington for this project. We await results of bathtub modeling exercise and climate scenario projections to integrate and validate models to examine effects of SLR and temperature and salinity changes on these habitats and engineering species. We have also assembled a historical layer representing native oyster (Ostrea lurida) habitat in Willapa Bay and are in the process of assembling data for oyster aquaculture and potential native oyster habitats in Coos Bay, Yaquina Bay, and Netarts estuaries in Oregon.
In 2010 a detailed evaluation of the Sea Level Affects Marshes Model (SLAMM) was conducted to understand and document the methodology. Activities included preparing input parameters for project areas, documenting derivations, requirements, best-uses and limitations. Uncertainty and sensitivity analyses were conducted for habitat change projections using 6 scales of digital elevation models (DEMs). Findings from this evaluation are scheduled to be presented at three professional conferences in 2011 and a manuscript is in progress. Outputs from SLAMM model runs 2000-2100 were provided to the Forest Service for evaluation of loss/gain in salmon habitat through 2100 in Poole Slough.
