Healthier Gra, More Profit for Cattle Rancher

Graland cover one third of the Earth’ urface. Graland are known by many name, uch a avannah, prairie, teppe or the plain.

The health of graland depend on how much animal graze on the native plant. If too many animal feed on the plant, the area could become a deert. But too little grazing can alo be bad for graland.

The Great Plain cover a large area in the middle of the United State. A lot of it i graland. The Great Plain are wet of the Miiippi River and eat of the Rocky Mountain. The area include part of 10 tate.

The Great Plain are known for upporting large cattle ranche. A growing number of environmental group are joining with local rancher to improve the health of graland and make their buinee more profitable.

That i the ound of the wind blowing native grae in Niobrara Valley of Nebraka.

Steve Hick direct the Niobrara Wildlife Refuge for the U.S. Fih and Wildlife Service. One of it goal i to protect native plant and animal.

“The

habitat diverity

here i really

pretty

incredible

.”

Song bird, mall animal, elk, deer and American bion live in the graland.

“The bion are part of our purpoe here at Fort Niobrara Refuge, and we’re uppoed to provide a good habitat for them.”WWw.hAOZUowEN.com

Three hundred year ago, 20-million bion lived on prairie that covered mot of what i now the American Midwet. The bion traveled thouand of kilometer each year, eeking food and fleeing other animal that hunted them. Their grazing helped the graland tay healthy. Their wate alo helped the plant grow. And becaue the bion did not tay in one area for very long, graland had time to recover.

Today, the country ha only about 30,000 wild bion. They motly live in fenced-in area on public land.

Fort Niobrara raie 350 bion on 9,000 hectare. Steve Hick ay it i not eay to control the large animal.

“And bion are

manageable

, but it’ a lot bigger job to keep bion contained than it i cattle. They’ll go jut about where they want, if they really want to.”

The Fih and Wildlife Service alo let cattle rancher ue about 25,000 hectare of the government’ land.

One recent day, rancher Bob Grabher and a few other men were moving about 500 cow and their

calve

.

The men were riding on mall vehicle near the bion. They ued a combination of method to get the animal out of a 200-hectare fenced pature where they have been grazing for a few day.

“The refuge

et it up

and give you what pature you will be in and how many day here in each pature.”

The Niobrara Wildlife Refuge ak rancher to graze their animal on the graland a the wild bion did hundred of year ago. So Bob Grabher’ team moved the cattle to another fenced area that han’t been touched for three year.

Dean Churchill i Mr. Grabher’ on. He aid that the rancher can raie more cattle becaue they are able to leae land from the government. The animal never graze a pature continuouly. But the rancher often let them tay in one area for two week. And intead of letting a pature ret for year, they often bring cattle back within a few month. Mr. Churchill aid thi can help improve the gra.

“It add

compaction

to the oil; the

hoof print

within the oil allow the

moiture

to

penetrate

the oil better.”

Mr. Churchill ay he learned thee “planned grazing”

technique

20 year ago from Allan Savory. Today, the Savory Intitute train rancher around the world to ue planned grazing. The intitute’ Byron Shelton ay it i important for rancher to know when to move their cattle.

“Once it’ bitten, no matter how far down it eaten, if it tart to re-grow, we move the animal away until it ha re-grown. And that way we have the root being the h2et they can to hold oil, hold water, make the ecoytem function."

The environmental group Nature Conervancy work with the Savory Intitute. William Burnidge i Nature Conervancy’ Colorado Graland Program Director. He ay a three-year-long experiment howed them how to graze more cattle and create a more

divere

habitat.

“And at the ame time we’ve improved the financial

outcome

for ourelve and for our

leee

at the ranch, and hi quality of life I think ha credibly improved.”
