Stop mowing - use goats

Many large government centers, including NASA GSFC, have to maintain expanses of grass as well as wooded areas. Mowing and edging the grass is a major waste of resources and a source of air pollution. In addition, invasive plants such as Japanese stilt grass and Bradford pear trees have taken over many of the unmaintained areas, which is not good for wildlife and can spread to neighboring properties. Perhaps herds of goats would solve both problems, and be less environmentally damaging. Some local cities (e.g., Gaithersburg) are doing that, using companies that lease, transport, and oversee their goat herds, particularly to deal with the invasive plant problem. Goats will eat anything and they leave only fertilizer.
