Outside of Cheyenne, Wyoming is an 8,900-acre former ranch where cattle and horses once roamed. Now it's just open land with nothing but grass. When the owner passed away he didn't have a succession plan. With no obvious heirs, a family member sold it. It eventually became subdivided and a realty company now advertises it for redevelopment primarily as retirement or vacation properties. Lesli Allison, executive director of the Western Landowners Alliance, doesn't want to see more huge ranches like this one broken up into pieces, each with houses and utilities."Then that landscape then is fragmented and is really not available to support agriculture or wildlife and the other values we care about in these landscapes," she says. "All the projections call for a massive transfer of land in the next decade," says Allison. "We're going to see many, many millions of acres of land change hands as these farmers and ranchers age."
