Eating invasive vegetation that compete for the scant water supply and inhibit the growth of grass, goats are a biblical-age solution to a modern-day scourge. To restore the land, 1,300 goats mimic the buffalo herds that once grazed the region – breaking the soil’s crust, stomping decadent grasses, knocking over dead trees, fertilizing with their droppings and embedding seeds. And, all the while, the goats voraciously defoliate and ultimately kill the water-guzzling Tamarisk.
