ATLANTA (AP) - Sheep have returned to the Georgia Tech to help deal with an invasive plant on campus.

The Atlanta Journal Constitution reports ( it's the second time the sheep have been brought to the campus to help control kudzu.

By grazing on the kudzu and any vegetation within their reach, the sheep eat away the root reserves. The process has to be repeated within 2 months.

Landscape project manager Jerry Young says it typically requires several grazing sessions with the sheep to manage a particularly overgrown area.

Anne Boykin-Smith, master planner for the school's Capital Planning and Space Management department, says using the sheep is a sustainable solution that doesn't require the application of pesticides, making it very eco-friendly.

The sheep are expected to remain on campus until Tuesday.
