This is very good:"Seattle-Tacoma has unleashed a herd of goats and sheep to graze on its property as an environmentally friendly way to eliminate weeds. The goats are being tested specifically to see if they can assist in grooming steep slopes and other hard-to-reach areas. The goats are contracted through local company Goat Trimmers, which uses rescued sheep and goats. 'Hate blackberry bushes? You may not love them, but our goats do! They're also hungry for thistle, weeds and other invasive plants,' Goat Trimmers' website says."
