The distance to foraging layer (Smi14_DisMOSH.tif) identifies the least-cost path distance for a piping plover chick to travel from the center of each 5x5 m grid cell to low-energy foraging areas with moist substrates. The distance to foraging data were used within a Bayesian network to model the probability that a specific set of landscape characteristics would be associated with piping plover habitat. The movement cost layer (Smi14_Cost.tif) identifies barriers to the movement of piping plover chicks, with barriers including water, human development, and moderate to dense vegetation. A value of 1 indicates possibility of movement and 99,999 indicates a barrier to movement. Barriers were identified using orthoimagery captured in 2014 (see data sources below). The movement cost layer was used to calculate the least-cost path distance (Smi14_DisMOSH.tif) to the nearest foraging area (Smi14_MOSH_Shoreline.shp). The foraging shorelines shapefile (Smi14_MOSH_Shoreline.shp) delineates foraging shorelines with moist substrates for piping plovers. Foraging areas were determined from elevations measured in 2014 and orthoimagery captured in 2014. Here, foraging shorelines are defined as low-energy and could include the shorelines of sound- or bay-side beaches, interior ponds, and ephemeral pools. Ocean shorelines were not considered low-energy foraging shorelines. See Zeigler and others (2019) for additional details.
