This species is considered endangered by the IUCN. Its numbers declined in the 1960s and 1970s due to loss of primary forests in its limited range, particularly along the major rivers in Russia. Current threats include illegal hunting, entanglement in (ghost) fishing nets and river pollution, as well as ongoing destruction of forest.
