Summary

Understanding how sea-level rise will affect coastal landforms and the species and habitats they support is critical for developing approaches that balance the needs of humans and native species. Given the magnitude of the threat posed by sea-level rise, and the urgency to better understand it, there is an increasing need to forecast sea-level rise effects on barrier islands. To address this problem, scientists in the U.S. Geological Survey (USGS) Coastal and Marine Geology program are developing Bayesian networks as a tool to evaluate and to forecast the effects of sea-level rise on shoreline change, barrier island geomorphology, and habitat availability for species such as the piping plover (Charadrius melodus) and seabeach amaranth [...]

Purpose

These data (tabular and point shapefile) include observational data of seabeach amaranth (Amaranthus pumilus) as well as random points added for analysis of habitat. Data from existing lidar, vegetation, and substrate datasets were sampled to measure site specific barrier island characteristics where seabeach amaranth was observed on Assateague Island National Seashore. In addition to compiling data where seabeach amaranth are present, an equal number of randomly distributed points were sampled from sites where no seabeach amaranth were present, for the purposes of analysis and the development of habitat suitability models.
