Overgrazing of pasturelands is a common problem in the mountain west, and we do our best to avoid the issue by implementing a rotational grazing system. The grasses that grow naturally in the valley have adapted to be grazed intensively and briefly by migrating ungulate herds. We replicate this natural process by grazing our horses in an electric fence enclosure, keeping them close together chomp, stomp, roll, and poop in a specific area--enriching the soil, and preparing it for next years growth. Every day the enclosure is moved and re-sized to guarantee that the horses will eat just the right amount of grass—not too much, not too little. After three years of implementing the system we have seen significant re-growth of lost grasses.
