The Eureka Dunes lie in an enclosed basin at Death Valley National Park in #California and cover an area that's only 3 miles long and 1 mile wide. At first glance, they appear desolate. However, plants and animals have adapted to survive on the shifting sands. Eureka dune grass is often the only plant found on the higher slopes of the dunes. Its dense root system catches and holds drifting sand, forming stable hummocks. Stiff, spiny leaf tips protect the plant from being disturbed by herbivores. Listed as an #endangeredspecies in 1978, the species is on the road to recovery as @USFWS moved the species to threatened in 2018!
