Habitat loss and degradation, pollution, reduced food availability (such as horseshoe crab eggs), and climate change are all major threats facing red knot populations today.
While red knots are considered Near Threatened under the IUCN, the U.S. Fish and Wildlife Service lists the rufa red knot as Threatened. States located around the Delaware Bay, an important stopover location for rufa red knots, are working to provide additional protections for red knots and horseshoe crabs. For example, New Jersey bans the harvesting of horseshoe crabs in the state and lists rufa red knots as endangered.
