On October 12,  released its annual assessment of “threatened and at-risk landscapes” in the United States. This year’s thirteen sites were organized based on five themes: “monetization of open space,” in which parks come under pressure to generate profit; “resource extraction,” which is under particular attack by Secretary of the Interior Ryan Zinke, who proposed relaxing management rules for six monuments, exposing them to mining and logging; “park equity,” charging to use parks or converting them to sport and cultural venues; “detrimental effects of shadow,” where the surrounding development is built up to the point where the park no longer receives adequate light; and “the devaluation of cultural lifeways,” in which ancestral lands and other sites of cultural significance are threatened.
