The city of Chicago is turning to a herd of goats for help with landscaping. The city’s Department of Aviation recently awarded a landscape contract to Central Commissary Holdings of Chicago to use a herd of 25 goats to clear four sites of excessive vegetation at O’Hare International Airport.

The Aviation Department said that using the goats is an eco-friendly alternative to using toxic pesticides and reducing fuel from lawn mowers and other landscape equipment; the animals consume about 250 square feet of vegetation per day. The contract will run through the end of 2013, and will pay up to $100,000.
