The Arnold Arboretum of Harvard University is clearing space for new plants by having a group of four hungry goats eat away weeds and unwanted vegetation.
The fence also protects the goats from rain and will keep possible predators at bay.
The enclosure will be moved around over the next few weeks so that the whole Arboretum can benefit from the goats’ work, the Arboretum said.
“If this method of biological control proves successful, the program may be expanded in the future and enable the Arboretum to minimize chemical control, reduce moving, and help us keep our plants and environment healthier,” the Arboretum said in a statement.
Other parks and grassy areas have launched similar programs using goats, including the West Street Urban Wild and George Wright Golf Course.
