Eco-goats are being used to take care of invasive vegetation at Haverford College in Bryn Mawr, Pa.
A suburban Philadelphia college is using goats to clean up an overgrown lot.
The Philadelphia Inquirer reports Haverford College brought in the 29 goats last week to start munching through 1 1/2 acres across from the school iconic duck pond.
School officials say the animals have already cleared out one section and have moved on to an even denser piece of land.
The goats have been hired from a company called Eco-Goats in Maryland.
School officials say they plan to follow up the goat operation with a human crew armed with machinery that will clear out was left and kill off stumps.
The goats are leased for about $400 a day, plus the cost of putting up a fence.
Officials say machinery for the job would cost $2,500 to $3,000 daily.
On a sign posted outside the fence, the Eco-Goats company boasts that their goats are helping the environment by eating Kudzu, Honeysuckle and other plants that are "major threats to healthy and sustainable neighborhoods and woodlands."
Goats are also used to remove poison ivy from around historic sites.
Eleven goats were recently dispatched to Fort Hancock in North Jersey to clear the six-acre site of the plant.
