Summer is the busy season for landscapers, and an unusual group of them were recently let loose on the perimeter of the historic Congressional Cemetery in Washington, D.C.

Fifty-eight goats spent a week at the cemetery to clean up poison ivy, invasive kudzu vines and English ivy that were killing some trees.

Officials say the goats were a lot less expensive than people — about $4,000 for a whole week, which works out to 25 cents per hour per goat.

"The revolutionary use of eco-goats eliminates the need for harmful herbicides and prevents the invasive and often foreign species from killing large mature trees in the cemetery's wooded area, which can fall onto the grounds as a result and damage invaluable historic headstones," reads a note on the cemetery's website.
