Travel Pulse reports that Portland International Airport is now using a herd of landscaping goats to remove (read: graze on) invasive plant life—blackberries, thistle, and Scotch broom—from the airport’s grounds.

What’s more, to protect the goats from predators, the airport has brought in a single llama. Really.

Not only are these four-legged workers getting a free lunch, human airport employees won’t have to mess around with harmful pesticides or maneuvering lawnmowers in hard-to-reach areas.

Believe it or not, these aren’t the first animals to find a job at this particular airport. You can find “Fish” the dog keeping birds off of the runways Monday through Friday after sunrise and before sunset, when the birds are at their most active. The location is also home to 29 controlled beehives—purely to help local beekeepers conduct research on the bees and their adaption to the Northwestern weather.
