The first thing Marcela Ortega did when she took over the management of the Cañon Verde Ranch in October 2025 was walk the south fence line with a pair of bolt cutters and a notebook.
The ranch sits at 7,800 feet in the San Luis Valley, ninety minutes south of Alamosa, on a long sage mesa that drops west toward the Rio Grande. For seventy-three years it had run between 380 and 520 head of cow-calf pairs depending on the year.
In May 2025 it was sold to the Sangre de Cristo Land Trust by the heirs of its third owner, a Pueblo dentist named Howard Velarde who had bought it in 1968 and grazed it lightly. The Trust paid 6.4 million dollars, most of it from a single anonymous donor in Boulder.
Ortega is forty-one, from Antonito, and spent twelve years on prescribed fire crews for the Forest Service before she came home. She is now the ranch's only full-time employee, with three seasonal hands who arrive in April and leave in late October.
The first task, she says, is fence. There are sixty-one miles of interior barbed wire on the property, almost all of it three-strand on cedar posts set in the 1970s. The crew has pulled fourteen miles since November.
Pulled fence does not photograph well. It comes out in stiff coils and gets stacked at the head of an old two-track, where a trucker from Monte Vista hauls it to a scrap yard in Pueblo for the price of the diesel. The posts, when sound, are sold to a man who builds chicken coops in Saguache.
The reason for the fence removal is not symbolic. Elk that move between the Rio Grande National Forest and the BLM land north of the property have, for fifty years, snagged calves and adults on the top wire, ripping muscle and leaving infections that kill slowly.
Pronghorn, which do not jump, have been blocked entirely. A 2024 GPS-collar study by Colorado Parks and Wildlife documented seventeen pronghorn making seasonal attempts on the mesa's western edge; none crossed.
The second task is water. Between 1971 and 1989, the previous manager dug a series of bulldozer pits in the major arroyos to slow runoff and provide stock tanks. They worked for cattle and ruined the hydrology.
Ortega's crew has begun installing one-rock dams and beaver-dam analogs, the latter built from juniper cut on site and pounded into the channel bottom with a hydraulic post driver borrowed from a neighbor in Mosca.
The technique is associated with Joe Wheaton's group at Utah State and has been used at scale on the Scott River in California and on a half-dozen tributaries of the John Day in Oregon. In the San Luis Valley it is new.
The expected result is not dramatic. The dams will catch sediment, the water table will rise by inches over years, and the willow that used to line these draws will come back from seed already in the soil bank.
There are no plans to reintroduce beaver. The Trust's biologist, a quiet man from Wyoming named Errol Tay, said in a January meeting that the watershed has to be ready before the animal can be asked to do the work.
Cattle have not been removed entirely. A neighboring rancher, Liana Coslett, runs 120 yearlings on the property between June and September under a conservation grazing lease, moving them in seven-day rotations across temporary electric fence.
The arrangement pays the Trust 11,400 dollars a year and gives Coslett summer pasture she would otherwise have to lease from the BLM at a less favorable rate. Both sides describe the relationship, when asked, as practical.
What is gone is the chemical regime. The previous owner had sprayed roughly 700 acres of sagebrush with tebuthiuron in 1994 to encourage grass for cattle. The treated patches are still visible on satellite imagery as paler polygons against the blue-grey of unsprayed sage.
Ortega says she will not spray again. The patches will fill in over decades, or they will not, and the answer will be visible only to people who walk the same ground over a long time.
In the meantime, a pair of Swainson's hawks has nested two seasons running in a cottonwood at the south end of the home pasture, which had been abandoned since 2018. The biologist's notes from May 2026 record two fledglings.
The Trust does not allow public access to the ranch and is unlikely to do so for at least five years. The reasoning, Ortega says, is that the land needs time without people, and the people who want to see it can wait.
She admits, at the end of a long afternoon spent re-staking an electric fence, that this is a slower project than her old fire crews would have tolerated. The fire crews wanted a line by dark. This work wants a decade.
What the mesa will look like in 2036 is not yet decided. Ortega's job, as she describes it, is to keep removing the things that are in the way and to leave the rest alone.
