At some point in my childhood, family friends raised goats. It seemed exotic. The Gordon children drank goat’s milk. And we learned that goats will eat anything when my brother tried to pat a goat and lost his mitten.
In addition to mittens, goats eat weeds, and increasing numbers of individuals and groups are deciding to use goats instead of herbicides to control weeds.
Evan Allen writes in the Boston Globe, “According to the US Fish and Wildlife Service, the use of goats to control invasive species, already common out West, is becoming more common across the East Coast.
“Goats love woody shrubs and vines, making them ideal weed-whackers. Using goats cuts down on the need for herbicides, and, unlike tractors, goats don’t require diesel fuel to do their job. And nimble goats can easily maneuver across rocky or marshy surfaces that humans and machines can’t safely reach.
“ ‘Folks are looking for long-term means of control,’ said Eric Schrading, private lands coordinator at the Fish and Wildlife Service. ‘As the last 30-plus years have gone by, we’ve started to, maybe not abandon chemical control, but use that as only one tool in the toolbox.’ …
“In Wellesley, the goats were shuttled out to the Boulder Brook Reservation in a bright pink truck driven by a crew from the Goat Girls: Hope Crolius, owner of the Amherst-based business, and two of her goatherds.” Read more here.

goats **are** so nimble! Seeing the baby goats nearby walking around the little ridge in the barn and climb up on things–and each other–they are so graceful and clever!
I’d heard of goats being used to keep down invasive phragmites; I’m happy to think of them being used more generally.
They have been known to deal effectively with trolls, too.
Yes they have 😀
Recently during a family walk in Berkeley we saw a “rent a goat” truck drive past. This sparked a lively conversation about whether we would prefer to have goats or lawn mowers cut our lawn. Nathalie and Pat (obviously sharing close genetic ties) were both in favor of gas guzzling machinery; Lola and I both adamantly in favor of goats!!!
I love the idea of a rent-a-goat truck. Near my work I saw an ordinary truck painted with bright colors and the words “Guy with a Truck, Somerville.” Believe me, if I ever need a truck, I’m going to track him down. Here’s a Yelp review: http://www.yelp.com/biz/the-guy-with-a-truck-somerville-2.
