On March 5, 1993 the western snowy plover was listed as a threatened species under the Endangered Species Act of 1973. The Western Snowy Plover Charadrius nivosus nivosus is listed as threatened due to three limiting factors: human disturbance, increasing native and introduced predator populations, and the loss and degradation of habitat. They are distinct from Western Snowy Plovers that breed inland 2. Western Snowy Plover Season (March 1 to Sept. 30) Seasonal restrictions will be in place for Surf, Wall and Minuteman beaches beginning Sunday, March 1, 2020 as part of the annual program to protect the Western Snowy Plover and its nesting habitat. To help ensure the survival of the species, California State Parks monitors Snowy Plover numbers and breeding efforts, and closes portions of beaches from spring through fall to protect nesting habitat. Volunteers also kept watch on plover signage and fencing, and contributed to plover habitat protection during all major holidays occurring in the Western Snowy Plover breeding season. The Western Snowy Plover is a small, light colored ground-nesting shorebird with black or dark brown markings on the head and breast. The population is at risk due to: • Habitat loss, primarily from invasive grasses. The Western Snowy Plover (Plover) is a small shorebird that can be found along the Pacific Coast from Baja California to Washington. Over the past 20 years, changes in coastal beach habitat along the Pacific coast, including heavy recreational use, urbanization, and inva- sion of exotic grasses, have resulted in loss of suitable breeding habitat for snowy plovers (Federal Register 1993, Page et … During the breeding season, March through September, plovers can be seen nesting along the shores, peninsulas, offshore islands, bays, estuaries, and rivers of the United States' Pacific Coast from Oregon to … We examined nesting success, causes of clutch failure and nest survival in relation to variation in substrate characteristics in a colour‐marked population of Western Snowy Plovers Charadrius alexandrinus nivosus breeding on riverine gravel bars in coastal northern California. For the last few decades the snowy plover population has declined, mostly due to habitat loss by human encroachment and environmental degradation. Plover Protection. The Western Snowy Plover is a threatened small shorebird, approximately the size of a sparrow. Due to these impacts, snowy plovers have stop-ped breeding at 52 ofthe 80 former western US coastal nesting locations (Page and Stenzel, 1981). Biology and life history. A small plover of beaches and barren ground, the Snowy Plover can be found across North and South America, Eurasia, and Africa. • Respect posted signage and symbolic fencing that identifies active nesting areas. Trash attracts scavenging corvids (crows and ravens), which directs unwelcome attention to plover eggs and baby chicks. As of June 19, 2012, the habitat along the California, Oregon, and Washington Coasts have been listed as critical. Interior-breeding birds utilize alkaline flats and salt pans associated with springs, seeps, or lake edges (Northern Basin and Range ecoregion). The Pacific Coast population of the Western Snowy Plover was listed as "threatened" under the Endangered Species Act in 1993 because of declining populations mainly due to loss of habitat. Western Snowy Plover Breeding Statistics The number of breeding snowy plover adults at Oceano Dunes has steadily increased over the years. It was listed in 1993 as a threatened species under the federal government’s Endangered Species Act (ESA). The western snowy plover is a federally protected shorebird. Plovers have lived on California beaches for thousands of years, but today human use of their remaining beach habitat seriously threatens their survival. This small shore bird is uniquely adapted to live and nest on the beach. Snowy plovers raise their young on unraked beaches in Coronado, Silver Strand and Imperial Beach. In North America it is restricted to the Gulf and Pacific coasts of the United States, and scattered inland localities from Saskatchewan to California and Texas. In 2006, Morro Coast Audubon Society created the Sharing our Shores Program to educate the local Morro Bay community about sharing the beach with Snowy Plovers.
