Petty crime and burglaries aren’t unusual in New Mexico’s isolated Guadalupe County, but lately Sheriff Michael Lucero has seen thieves steal something a bit unexpected: grass.

With drought drying out grazing land and driving up hay prices, some ranchers in New Mexico have started cutting neighbors’ fences or leaving gates open so their cattle can graze on greener pastures.

Authorities in other drought-stricken states say they’ve seen similar fence cuttings, along with thefts of livestock and other materials as ranchers struggle to stay in business. In some cases, stealing a neighbor’s grass may be the only way for a rancher to feed his livestock, but victims say their livelihood is being threatened too.
