They’re back: a herd of goats will once again visit the Congressional Cemetery to chow down on some vegetation.

For the second time, the Association for the Preservation of Historic Congressional Cemetery will bring a heard of 30 or so goats from the Prosperity Acres in Maryland to graze in the Cemetery for a couple weeks. The goats are known to munch on invasive species of plants—like vines poison ivy, and other greens—while “depositing slow-release nitrogen fertilizer (goat poop), which keeps the Cemetery looking nice without having to use herbicides and other chemicals.

And the goats will also be protecting more than just the visual appeal of the Cemetery. The PHCC says that the honey bee population in the cemetery is perpetually at risk because of the invasive vines that often forces out the native plants that honey bees love to pollinate.

The goats first visited the cemetery in August of 2013 for the same ground-keeping purposes. “We were amazed two years ago at the sensation these little guys caused, but when we saw the excellent job they had done, it made complete sense to bring them back again,” President of Historic Congressional Cemetery Paul K. Williams said in a statement.

The goats will be there from August 6th to 20th, and the public is encouraged to come check them out. Perhaps the PHCC can get Goat to perform for the goats. That’d be cool.
