n northeastern Montana,
At 60,000 acres, the Matador, which The Nature Conservancy has owned since 2000, is the largest private ranch in the region. But even with all that land, Brian Martin, the director of science for the Conservancy in Montana, has been thinking about the ranch’s role in keeping an even larger landscape intact.
Here on the prairie, small but important creatures need big spaces. There’s no better example than the greater sage grouse. Not much bigger than a chicken, sage grouse are what biologists call a landscape species. They depend not on a patch of turf but on a sweep of ground and sky big enough to provide a reliable variety of habitats: sagebrush of one size for nesting and another for winter survival, broadleaf plants for rearing chicks, bare ground for mating rituals. These birds, an important food source for everything from foxes to eagles, often fly scores of miles to find what they need.
But the sage grouse, along with a suite of other prairie species like prairie dogs, long-billed curlews and migrating pronghorns, are finding that their world isn’t as big as it used to be. It has been whittled down by roads and fences and, most severely, the plow. And a smaller world can bring trouble for both humans and birds. Lose the bigness and you lose birds. Lose birds and you invoke the restrictions of the federal Endangered Species Act. This isn’t a theoretical problem: The U.S. Fish and Wildlife Service is scheduled to decide whether to add the sage grouse to the endangered species list by 2015.
But the Conservancy is using an innovative idea to preserve the open range and keep the prairies functioning for increasingly rare creatures—as well as for the scattering of ranchers who’ve made a home here in the sagebrush. As big as it is, the Matador remains a relative postage stamp on the prairie. So the Conservancy is working with its ranching neighbors to operate a grass bank, a conservation tool designed to save the prairie far beyond the ranch’s borders.
“We don’t want random acts of conservation out on the landscape,” Martin says. “We want large blocks. For the landscape-scale species we’re interested in, that’s what they require.”
Southern Phillips County, Montana, isn’t HOME to a lot of people, but the prairie here is no stranger to controversy and mistrust. “I’m 50 years old,” says local rancher Dale Veseth, “and it seems there’s always been a fight.”
But the Conservancy is trying a different approach. Working from a model established in the 1990s on a former Conservancy property in southern New Mexico and Arizona, the organization has established a grass bank on the Matador. The goal is to improve both wildlife habitat and ranch profits, and to leverage those improvements far beyond the borders of the Matador.
Here’s how it works. The Matador has a lot of grass but no cattle. The neighboring ranchers have a lot of cattle but not always enough grass to last the year. If ranchers commit to adjusting the way they manage their own properties, the Conservancy gives them a substantial break on the cost of grazing leases at the Matador. That means ranchers have better wildlife habitat on their own places, as well as more grass for their own cattle.
The most important commitment ranchers make is a promise never to “bust sod.” The American prairie is an incredibly resilient ecosystem: It can withstand raging fires, millions of hooves, cold that can crack a stone and withering drought that lasts for years. But it can’t survive a plow. And agricultural economics, a growing population of hungry humans, and federal farm and renewable energy programs have created incentives over the decades to break ground and plant grain.
Each year, more than 1 percent of grassland in the northern Great Plains’ Prairie Pothole region is lost, which means it’s being converted faster than Amazonian rainforests. That whittles away at the bigness that’s so critical for prairie species. Converting prairie grasses to grain crops brings roads and disruption, replaces plant diversity with monoculture, alters habitat. For example, a plowed field can disturb a sage grouse breeding ground, or lek, as far as two miles away. Native grasses, in contrast, eventually become a kind of mulch that slows erosion, helps retain water in the soil, and improves nesting success for sage grouse and other ground-nesting birds.
That’s why the Conservancy wants to keep the remaining prairie right side up. “If you ever break native prairie, you’re out of the grass bank forever,” Martin says. “You can’t come back in.”
Those kinds of protective actions—and the discounts that come with them—translate into tens of thousands of dollars in savings for ranchers in a tough business. Every year, the Matador hosts about 1,000 yearlings and 860 cow-calf pairs, plus some bulls. In 2013, the average price for leased private pasture in Montana was $21 per month per cow and calf. But on the Matador, ranchers have qualified for enough conservation incentives that they paid as little as $10.50 per cow and calf.
Leo Barthelmess’ family has been in the grass bank since 2007. Being able to run cows on the Matador at reduced costs means the family can save its own grass and doesn’t have to buy as much hay in the winter. “Not having to feed that hay is a big deal,” says Barthelmess, who has been honored by Montana State University, the federal Bureau of Land Management and the Montana Stockgrowers Association for his conservation ranching.
The grass bank has changed the way Barthelmess and his neighbors think about what they do. “We were a little skeptical at first,” he says. “But it’s working for us. It’s got ranchers thinking about birds, and conservationists thinking about cattle.”
After 10 years, the Matador’s grass bank now stretches its conservation benefit to 220,000 acres of non-Conservancy ranchland here.
When the conservancy first arrived, Says rancher Dale Veseth, “we were concerned about how they might fit into a small, close-knit community.” Veseth is a well-spoken, well-educated native of the prairie—his ranch has been in the family for a century—and now he’s an enthusiastic member of the grass bank who sits on the board of the Conservancy’s Montana chapter.
He points to an upcoming program through which the Conservancy will help ranchers write management plans for their properties. Those plans will aim to improve both wildlife habitat and ranch income and give ranchers reliable data on what works and what doesn’t.
“It’s nice to have a good database,” says Veseth, whose ranch has 67 pastures, each unique in some way. And he appreciates the Conservancy’s technical expertise in finding ways to manage them better by altering grazing patterns and intensity over both space and time to make the land more productive.
“If the Conservancy had approached us 10 years ago and said, ‘We want to write a range management plan for your place,’ I know I wouldn’t have taken them seriously,” he says.
