Due to population declines and habitat loss, the northern harrier was listed as a threatened breeding species in New Jersey in 1979. Conservation practices that could benefit this species include protection of large wetlands and grasslands, keeping reclaimed surface mines in grasses rather than trees, and reclamation of old field or grassland habitats in core or historic range areas through easements or CREP-type landowner programs. It was quite a different story in 2020, with State Wildlife Grant (SWG) funds from NH Fish and Game sufficient to cover the full 2020 breeding season.
