Restoring Biocrust

Drylands encompass over 40% of terrestrial ecosystems and face significant degradation from a warming/drying climate and overuse. To combat this degradation, some restoration efforts have focused on the use of biological soil crusts (biocrusts): complex communities of cyanobacteria, algae, lichens, bryophytes, and other organisms living in association with the top millimeters of soil. We talk with Anita Antoninka, Dept. of Forestry at Northern Arizona University, about the current knowledge in biocrust restoration. These efforts effectively restore biocrusts in different ecosystems using a variety of lab and field methods, providing a useful resource for the scientific community as well as land managers.

Wild Horses in the West

Horses evolved on the North American landscape since the 1400s in a grassland ecosystem. Yet, all of the wild horses that exist today across the western states live in deserts, sagebrush steppe, or other shrub dominated systems. We talk with range scientist Eric Thacker about the growing number of wild horses across the west and the need for horse management in order to maintain the fragile ecosystems that they graze on.

Dynamic Desert Ecosystems

Changes are happening in plant communities in deserts of the Colorado Plateau and around the world. We speak with Dr. Steve Archer from the University of Arizona about the shifts in ecosystems primarily made up of grasses to those of woody plants and shrubs.  The effects of this shift are wide reaching and have large effects for desert systems that we know.
