McDowell Sonoran Conservancy: Desert Surfaces – Educational Walk

What really covers the desert – little organisms can make a big difference!  Some of the most common sights in the desert – and indeed the living things that probably cover more of the desert than any single kind of plant – are lichen, desert varnish, and soil crust. These organisms actually have much in common. Among other things, they’re all alive (yes, even varnish), they have some components that are neither plants nor animals, and living filaments are crucial to their existence. Come learn more in this introduction to what really covers the desert.

Our walks are usually short (around one mile in length) and easy. They often explore the interpretive trails of the Preserve, which are very accessible and near the trailheads. Activities begin promptly at the start time, please arrive 15 minutes before the start to prepare and check-in.
