Conservation

Conservation DecliningSnowy Plover populations are declining. A 2012 study estimates a total population of 2,900 on the Pacific coast, and 25,900 in the interior and eastern coasts of North America. Snowy Plover are listed as Near Threatened on the IUCN Red List, and the Pacific coast population is listed as threatened in the U.S. and Mexico, and is on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. The species is also listed as endangered or threatened in several states. Breeding populations have likely decreased on Gulf Coast since late 1800s owing to habitat alteration and increased recreational use of beaches.Back to top
