Too often, droughts grip the West, bringing misery to producers.
Ranchers who perpetually manage their pasture, rather than reacting
to drought with emergency measures, stand a better chance at staying
viable through periods of little to no precipitation.
British Columbia’s Ministry of Agriculture and Lands recommends
matching herd size and breeds to the feed and water available on
the ranch. Consider moving livestock to rented pasture or weaning
early, which may help condition cattle to less feed. Knowing your
area’s average precipitation patterns and keeping an eye on
rainfall patterns may help you stay ahead, as you can sell off part
of your herd early before others flood the market and reduce prices
for calves or beef.
Adding small ruminants such as goats and sheep to your cattle
operation can deflect the effects of drought, since large and small
ruminants have different forage requirements. Finally, when drought
strikes, send your herd to graze drought-stricken crops to salvage
their value. (However, monitor residues from drought-stressed crops
for prussic acid and high nitrate levels.)
Ranchers, contending with record droughts in recent years, have
adopted such strategies. Mark Frasier, who ranches with his father
on 29,000 acres in eastern Colorado, works hard to maximize the
scarce precipitation. After educating himself in Holistic Management®,
Frasier initiated a system of herd management that moves his cattle
among 125 paddocks, depending on the availability of water and feed.
Native plants, Frasier says, are the only species he can count on
consistently.
The Frasiers also focus on soil management, using the animals
to break up crusted soil surfaces and monitoring range productivity.
“Even during a drought, rain does fall, and it is imperative
that the soil surface be prepared so that rainfall is effectively
conserved,” Frasier said. Only once, during the most severe
drought conditions, did the Frasiers sell off their stock.
Similarly, rancher Steve Sinton, who won American Farmland Trust’s
2005 national Steward of the Land Award, applies keen herd management
to his 18,000-acre ranch in central California. After a drought
in the 1970s wiped out his pastures, Sinton and his father, Jim,
overhauled how the family runs cattle. Today, Steve Sinton monitors
range conditions and stocks the pasture at herd densities that support,
not overpower his forages. He also changed the ranch’s schedule,
selling calves sooner – at the calf stage rather than yearling
– if conditions so dictate.
“You have to graze at the right level,” he said. “Our
philosophy is to leave enough grass so that if it doesn’t
rain until February, the herd can make it.”
