RestoreNet is a networked ecological experiment testing restoration treatments across the arid Southwest. Seven experimental sites were installed in the Summer of 2018 on the rangelands of Northern Arizona. The experiments tested seed mixes with various treatments to increase revegetation success (see photos above). These are the results after the first year.
