Migratory species are an important ecological link between the Arctic and the rest of the world. The threats facing these species include overharvesting, habitat degradation and low population densities. Populations and migratory patterns can also be affected by pollution, invasive species and the northern expansion of southern specie. International coordination is key to successful conservation because migratory species face threats across their whole migratory range.
