WASHINGTON (DC News Now) -- The Rock Creek Golf Course has some new recruits to help remove invasive plants -- goats. "It was so overrun with vegetation that it just wasn't possible for us to ask volunteers to go in there," said Andrew Szunyog, the director of sustainability with National Links Trust (NLT), which operates the course. It's the first time that NLT has used goats, which are from RVA Goats out of Richmond, Va. "They're bread for it. Hundreds and thousands of years of evolution and domestication," said RVA Goats Project Manager Summer Orcutt.

They are also seen as a natural alternative to chemical herbicides -- and they cut down on labor costs. Sheep are also used in this project, but Wednesday's conditions -- and where the clearing is taking place -- prevented them from being used. "It's just a great scene. I love it, and I'm also such a wild golfer that I hit it in the brush and lose a lot of balls. So there's a lot of benefits here," said D.C.'s Joe Sill. The animals are expected to wrap up their work in about a week. If you would like to see the animals, you must first contact the golf course.
