Officials with the city's Wascana Centre Authority have hired about 90 of the bleating eating machines to rid the shrubs from a conservation area of the park where the greenery has gotten out of control.
Naturalist Jared Clarke says caraganas were once planted in rows to delineate property lines, but they ended up choking out native species of grass and other plants.
Clarke says the goats are an alternative to using herbicides and seem to work better than mowing, which is a temporary fix.
The more the goats gnaw away at the leaves, the harder it is for the shrub to grow back.
It's not the first time goats have been brought in to do what they do best — Amazon used them at its offices in Japan and they've also been deployed at the San Francisco airport.
The goats will be on duty until Monday, when they will stand down and be transported back to their farm in Edenwold, Sask.
Clarke says if the project is deemed a success, the goats could be brought back again in the future. (CJME)
