Good cow, bad cow, a two-headed question over cattle on the range

At Red Canyon Ranch, cattle are being trained to spend more time grazing away from stream banks. At the Grey Ranch in Arizona, grazing research plots of five square miles each are being used to study the interaction of cattle, fire, climate, and prairie dogs. The Nature Conservancy sees cattle as part of the solution to overgrazed stream banks in the West. (Nature Conservancy July/August 12-19)
