Cities and organizations in the US state of Maryland have found an original and ecologically sound method to cut the weeds from their parks and gardens: Bring in the goats.
Vegetation in towns and cities can make a significant contribution to carbon storage and, ecologists say, could lock away even more carbon if local authorities and gardeners planted and maintained more trees. The study, published this week in the British Ecological Society's Journal of Applied Ecology, is the first to quantify how much carbon is stored in vegetation within an urban area of Europe.
