The ecoregion has few protected areas. They include Dicky Private Wildlife Reserve ("Refugio Privado de Vida Silvestre Dicky") and Magallanes National Reserve on the mainland, and Reserva Costa Atlántica in Tierra del Fuego. The Patagonian Grasslands of Argentina Conservation Project, organized by The Nature Conservancy, is trying to develop sustainable grazing practices in partnership with scientists and landowners, but it is a challenge to find economic incentives.
