The International Piping Plover (Charadrius melodus) Census provides a snapshot every five years of the distribution and abundance of this species of conservation concern. The Piping Plover is a widely distributed but rare species with three breeding populations. The entire species is federally listed as endangered in Canada, and the Great Lakes Population is listed as endangered in the U.S., with the U.S. Plains and Atlantic coast populations listed as federally threatened. The International Piping Plover Census remains the most comprehensive inventory for this rare species. 20160516 20160722 ground condition Complete None planned United States and Canada -114.8000 -53.4000 55.9000 38.1000 ISO 19115 Topic Category inlandWaters environment biota None piping plover Charadrius melodus shorebird USGS Thesaurus birds long-term ecological monitoring animal and plant census partnerships ornithology endangered species population dynamics interagency programs human impacts USGS Metadata Identifier USGS:61200cd9d34e40dd9c02013e Common geographic areas United States Canada None Charadrius melodus Kingdom Animalia animals Subkingdom Bilateria Infrakingdom Deuterostomia Phylum Chordata chordates Subphylum Vertebrata vertebrates Infraphylum Gnathostomata Superclass Tetrapoda Class Aves Birds Order Charadriiformes Shore Birds Gulls Alcids Plovers Oystercatchers Auks Family Charadriidae Plovers Genus Charadrius Ringed Plovers Species Charadrius melodus Piping Plover TSN: 176507 No access constraints.
