o Global climate change and sea-level rise, which places even greater stress on coastal habitats. Global climate change will continue to alter conditions on the breeding grounds (e.g., timing and availability of food resources, predation pressure, and competition), and at migration stopovers (due to sea-level rise and droughts), with unknown consequences for this species. o Threats during nonbreeding seasons. Threats exist at most sites where Sanderlings occur, and include: habitat loss, alteration of habitat (e.g., beach stabilization, beach ‘nourishment’, mechanized beach raking, and sand excavation for construction), widespread recreational disturbance, and pollution – especially oil pollution, as this species occurs mainly on marine shorelines during the nonbreeding season. Agrochemicals and plastic bi-products are also a likely threat, although their effects are not yet understood; and o Harvesting of primary food source at migration sites by humans (e.g., Horseshoe Crab eggs). Conservation activities recommended to address these threats are: o Identification and protection of existing habitat; o Management of and education at existing protected areas to reduce disturbance; o Management of Horseshoe Crab harvest to ensure adequate food for migrating shorebirds; o Work towards new legislation to reduce pollution (including greenhouse gases); o Increase regulations (e.g., beach closures, leash laws) where necessary. The relative importance of these threats to the Sanderling during different life stages is not yet well understood, and a better understanding is necessary if we are to achieve the greatest impact of conservation and management actions. However, it is clear that the habitat preference by Sanderlings (i.e., sandy beaches) puts them at risk due to constant disturbance from humans, as well as from (oil) pollution, development pressure, various beach stabilization/aesthetic activities, and sea-level rise. Sanderlings share habitat with other coastal specialist shorebirds (especially Whimbrel and Willet) and many other coastal species both marine and terrestrial, and conservation efforts WHSRN – Sanderling Conservation Plan, February 2010, v1.1 2
for Sanderlings will benefit other species. In some areas, the Sanderling is a key ‘umbrella’ species, such as along the Pacific coast of South America where it is the most common coastal shorebird species from Peru to Chile. Conservation of the Sanderling would benefit waterbirds and other coastal species along the entire southern part of its wintering range. Figure 1. Distribution of the Sanderling in North and Central America and the western West Indies. This species also breeds from Greenland through northern Europe and Asia, and winters in the eastern West Indies and in South America (see Figure 2).
