Officials at Harvard University's Arnold Arboretum have gotten creative with their effort to clear space for new plants.
The Boston Globe reports (http://bit.ly/2cKplhq ) four hungry goats have been contracted to eat weeds and other unwanted vegetation at the Ivy League school's arboretum in Boston.
Officials say the goats are being kept at the arboretum in a small, electrified enclosure that allows them to work on one area at a time. The enclosure will be moved around the preserve during the next few weeks to take advantage of the goats' voracious appetite.
A statement released by the arboretum says the goats have helped minimize chemical control and the program may be expanded in the future if it proves successful.
