The busiest ski resort in the U.S. is using goats instead of herbicides to get rid of weeds on its slopes. After the goats eat their fill, the Vail resort in Colorado is seeding the areas with native plants to fight off alien weeds. The goats are owned by Lani Lamming, who rents them out for $1 per day per goat, plus the cost of shipping. Lamming’s company, Ewe4ic Ecological Services, has been in business for four years, renting to businesses in Montana, Nebraska, Oklahoma, and Utah, as well as Colorado.
