You’ll also find sand dunes in the Fiery Furnace. Sand dunes are an important habitat for many plants and animals. They’re a great place to spot rodent burrows and lizard tracks. Dunes are stabilized by plant roots hidden in the sand. Walking or jumping on them uncovers and breaks these roots. The disturbed sand then blows away, burying and killing other plants and depriving animals of shade, food and shelter. By not walking on sand dunes, you’ll help preserve the shade-giving trees and plants that support the Furnace’s animal communities. If the path you’re on leads to a sand dune, patch of soil crust, or vegetation, just retrace your steps and find another route.
