Rancher John Haskell looks over a
riparian area on the Hardware Ranch in
Utah
. He said that
excluding cattle allowed thistles to take over. When
cattle conditioned to eat the thistles were
introduced, grass returned. The thistles are still
there, he said, but in far fewer numbers.

HYRUM,
Utah
- The debate seems endless. Environmentalists contend
removing livestock will improve rangeland, while ranchers say
properly managed grazing is best for the land.
John Haskell can prove cattle grazing can be good for rangeland,
even on land set aside as big game habitat.
The
Utah
rancher runs about
1,000 head of yearlings on the 55,000-acre Hardware Ranch, a state
wildlife preserve managed since the late 1940s by the Utah
Division of Wildlife Resources. The proof lies in pictures he has
showing riparian exclosures no longer overrun with thistles, brush
rebounding on deer wintering range and noxious weeds such as
dyer's woad disappearing inside fence lines even as it thrives
along the road outside those same fences.
There's also plenty of monitoring data proving grass and forbs are
rebounding on summer and transitional, spring and fall range, he
said.
The results are dramatic enough that Haskell was asked to speak at
the National Grazing Lands Conservation Initiative symposium in
St. Louis
last December.
The Hardware Ranch was historically a sheep ranch, but also a
major winter area for the Cache mule deer herd and elk. Moose and
sage grouse are also native to it. The state purchased it to
resolve major conflicts between growing big game herds and
agriculture in
Cache
Valley
, the region around
Logan
,
Utah
, Haskell said. The
goal was to feed elk and provide for the Cache mule deer herd each
winter, stopping crop depredation.
The operation quickly became an educational, hunting and tourism
opportunity. The ranch, in the foothills of
Utah
's rugged
Wasatch
Mountains
, drew tens of
thousands of winter visitors for sleigh rides and elk-viewing, he
said. Hardware Ranch is well known throughout northern
Utah
and into southeast
Idaho
.
Habitat declined
"The trouble was, the quality of the habitat declined under
state ownership," Haskell said. "It was especially bad
in winter feeding areas. The elk were fed, but the deer were left
to browse on the sagebrush. They soon put so much pressure on the
brush that heavy grass began taking over the land. The deer
started looking elsewhere for feed."
Noxious weeds were the second major problem. Dyer's Woad, spotted
knapweed, cheatgrass and medusa head rye were especially
aggressive, taking over vast acreages. Thistles, though not
officially on the state noxious weed list, also increased greatly,
he said.
Mechanical treatment wasn't an option. The ranch is on steep,
rocky ground. Restoration seedings or herbicide spraying with land
rigs would be impossible and prohibitively expensive. Aerial
treatments were also too costly to be considered, he said.
"About five years ago a personal friend who is a wildlife
biologist called to discuss the problem. He asked if it would be
possible to graze cattle in a given area hard enough to knock the
grass back, allowing the brush to grow," Haskell said.
"I told him, 'Sure! That's exactly what our forefathers did
before they knew any better.'"
It took another year to a year and a half to sell the idea to
other agency personnel. At last, Haskell received a grazing
contract.
He manages his yearling herd differently for each part of the
ranch.
"We hit the winter range areas hard, removing enough grass
and weeds to leave bare soil behind. That gives sagebrush the
opportunity to spread," he said. "Our herd is rotated
through a series of pastures from 500 to 1,000 acres in size every
two weeks.
"That's only about a third of the ranch. The other two-thirds
of the land is summer, spring and fall range. There, the goal is
to stimulate the grass and forbs to create good feed for grazing
when elk and deer come back into this country each fall,"
Haskell said. "We go for short-duration grazing and very low
utilization. Ideally, we use only 25 percent of the forage. Our
cows move every five days to two weeks."
Fenced riparians
Finally, the ranch already had several fenced riparian exclosures.
In some cases fences were low so elk and deer could easily get at
the browse inside. Other riparian zones were surrounded with
eight-foot fences to exclude even them. All were overrun with
thistles and noxious weeds.
Haskell turns from 150 to 250 head of cattle into those areas for
at most a day or two at a time. That's enough to knock back the
wolf plants and weeds.
Haskell's participation in what is officially a habitat
restoration project is not unrewarded. The rancher is paid so long
as he meets the objectives of the program. That payment is very
small, though, working out to about $2 an acre, he said.
"When we started the ranch had no infrastructure at all,
except for a very little fencing. Most of it needed
maintenance," he said. "We're gradually installing more
permanent fencing, but we also use a bunch of temporary electric
fence. We had to develop cattle water sources."
Some claim cattle won't eat cheatgrass, spotted knapweed or dyer's
woad. In fact, cheatgrass is 75 percent protein and very palatable
to livestock when green, the rancher said. They must be turned out
on it before it dries and goes to seed.
As for the other noxious weeds, Haskell works closely with Fred
Provenza, professor of range animal production in the Department
of Wildland Resources,
College
of
Natural Resources
, at nearby
Utah
State
University
in
Logan
. Provenza has done
extensive work in training cattle to eat weeds most assume they
won't touch, the rancher said.
"We turn out on the Hardware Ranch any time the grass is
ready, from March 15 to April 15, generally around the first of
April," Haskell said. "The herd stays on the winter
range until about the first of July, if there's enough feed. Then
we start moving through the other pastures for the rest of the
summer, into fall. We keep the herd in one unit as much as
possible."
Grazing in designated wildlife habitat isn't without its special
challenges. Haskell recently hosted a group from Trout Unlimited
on a tour explaining the project. A member of that organization
had seen his cattle in a riparian zone and became concerned,
leading to the group's visit.
"They were quite astonished when I showed them the pictures
with the thick blanket of thistles in that exclosure before we
started. You can still find thistles there, but they've been
knocked back considerably," he said.
