Economic Importance and Threats
Importance:  Ecosystem balance
(Sanderlings are important predators of marine crustaceans in the intertidal zone. They are found in association with a wide variety of other shorebirds in foraging flocks in winter and migration, including dunlins (Calidris alpina), red knots (Calidris canutus), black-bellied plovers (Pluvialis squatarola), willets (Catoptrophorus semipalmatus), dowitchers (Limnodromus), ruddy turnstones (Arenaria interpres), semipalmated sandpipers (Calidris pusilla), western sandpipers (Calidris mauri), two-banded plovers (Charadrius falklandicus), and white-rumped sandpipers. There is competition among these birds for food items, and larger shorebirds, such as Franklin's gulls (Larus pipixcan) and gray gulls (Larus modestus), will steal prey from sanderlings.

Sanderlings are parasitized by several nematode species that they get by eating aquatic crustaceans.)
Importance:  Commercial
(Sanderlings are interesting members of arctic, temperate, and tropical coastal habitats. Historically they were considered a game species and were hunted for market. Arctic natives collected eggs to eat.)
Threats:  Anthropogenic
(The species is sensitive to disturbance on beaches (e.g. from recreational activities and free-running dogs), also this species is threatened by the degradation and loss of wetland habitats through environmental pollution, reduced river flows and human disturbance.)
Threats:  Natural threats
(This species is susceptible to avian influenza so may be threatened by future outbreaks of the virus.)

Ecology
Habitat:  Estuarine, Sandy, Muddy, Coastal
Trophic Level:  Consumer
Prey:  Carnivorous-tiny crustaceans, molluscs and other small animals.
Predator:  Known Predators parasitic jaegers (Stercorarius parasiticus) long-tailed jaegers (Stercorarius longicaudus) glaucous gulls (Larus hyperboreus) snowy owls (Nyctea scandiaca) wolves (Canis lupus) arctic foxes (Vulpes lagopus) merlins (Falco columbarius) peregrine falcons (Falco peregrinus) cinereous harriers (Circus cinerea) burowing owls (Athene cunicularia) short-eared owls (Asio flammeus) Sechuran foxes (Lycalopex sechurae) laughing gulls (Larus atricilla) house rats (Rattus rattus) domestic cats (Felis catus)
IUCN Status:  Least Concern
