U.S. Fish & Wildlife ServiceModelling the potential for alternative management strategies to improve the conservation status of saltmarsh sparrow and other tidal marsh specialist birds. Christopher Field, Department of Natural Resources Science, University of Rhode Island Chris Elphick, Ecology and Evolutionary Biology, University of Connecticut June 25, 2020 Please direct any questions to: Christopher Field christopher.field@uconn.edu Data sources Saltmarsh sparrow abundance estimates are from Wiest et al. (2018). Marsh patch boundaries follow Wiest et al. (2016), who used a 50-m buffering approach to group marshes into biologically-relevant units using the U.S. Fish and Wildlife Service's National Wetlands Inventory (https://www.fws.gov/wetlands/nwi/). Forest loss is the area within 100 m of tidal marsh that experienced loss between 2000-2018 (as a proportion of the patch), from Hansen et al. (2018). Area of marsh (ha) that is behind a tidal restriction is from University of Massachusetts Landscape Ecology Lab's Designing Sustainable Landscapes: https://jamba.provost.ads.umass.edu/web/lcc/dsl/metrics/DSL_documentation_tidal_restrictio ns.pdf. Sea-level rise rate (mm/year) is from the NOAA tide gauge that is closest to the marsh patch.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/18e4edc90b96434d966ae02c5fce153c_0engU.S. Fish and Wildlife Service Open DataPublicSHARP patches 100m USFWSsals SALSvSLR [United States]Web servicesUnited StatesLast Modified: 2021-06-07
