Seeding on rangelands has a high rate of failure, which makes restoration difficult. Yet many landowners and managers are eager to know what works to restore degraded rangelands.
Restoration on Degraded Rangelands to Benefit Managers in Colorado
In 2021, Dr. Carrie Havrilla of the Dryland Ecology and Management Lab, Emily Lockard, Retta Bruegger of CSU Extension, and others established two research plots in southwest Colorado test strategies for restoration on degraded rangelands. We use seed mixes adapted for current and future climate and pair seeding with additional strategies to increase soil-moisture retention and ideally restoration success. The experiment lasts for 10 years.
Learning how to Restore Degraded Rangelands from Across the Southwest
The experiment is part of a network of sites across the southwestern US, led by the US Geological Survey, called RestoreNet.
