Goats munch on invasive weeds in NYC park

STORY: It's an environmentally friendly win-win for invasive species removal at Riverside Park - the goats get to feast on overgrown brush and the Riverside Park Conservancy doesn't dump harsh chemicals on weeds and poison ivy.

"They love this stuff. They eat poison ivy, they eat the porcelain berry, they eat the multiflora rose and that's what we're trying to get rid of," said John Herrold, interim president and CEO of the Riverside Park Conservancy.

He said the goats can also get to plants on steep slopes.

Of the 20 goats, four will call Riverside Park its home through the end of summer, eating their way through two acres of the park.
