What is Rangeland?

Rangeland is uncultivated land dominated by native plants: grasses, herbaceous broad-leaved plants (forbs) and shrubs.

Rangeland is all land that is not farmland, dense forest, barren desert or land covered by solid rock, concrete, or glaciers.

Rangeland includes: grasslands, shrublands, savannas, and open woodlands .

Are all rangelands grazed? Grazing as an important ecological process in all rangeland, but

not all rangelands are grazed by livestock.

36% of the US is rangeland

53% of Western States is rangeland

Who owns rangeland? In Idaho, 66% of all rangeland is “Public Land”. “Public land” is owned and managed by federal and state

governments for the good of the public. In Idaho, the most important land management agencies are

the Bureau of Land Management, the U.S. Forest Service, and the Idaho Department of Lands.

Grazing on private lands is wholly integrated with public grazing lands. Livestock grazing occurs on 95% of BLM land and, 58% of U.S. Forest Service lands. 88% of all beef cows in Idaho graze at least part of each year on BLM

or USFS lands.

List 5 uses or services rangeland provides?

What is rangeland good for?

Livestock Production Rangeland & pastureland in the 19

western states are home to 58% of all beef cattle in the US.

Western rangelands also harbor 79% of sheep and 88% of goats in the US.

Livestock production on rangeland is very important to supply meat for American and World populations and also for leather, wool, mohair, and other products that livestock yield.

What is rangeland good for?

Livestock grazing occurs on 65% of Idaho’s total land area and in every county throughout the state

Range livestock production is Idaho’s major agricultural activity in terms of land used and cash receipts

Wildlife Habitat Rangelands provide habitat for countless

mammals, birds, amphibians, fishes, and insects.

Of the total number of animal species found in the United States 84% of the mammals, 74% of the birds, 58% of the amphibians and 38% of the fishes are represented in

rangeland ecosystems.

Range Wildlife Include: Ruminants are animals such as deer, elk, and moose

that have specialized digestive systems to digest the cellulose abundant in the cell walls of rangeland plants

Rodents and Rabbits also have digestive systems that allow them to get energy out of cellulose

Concentrate-selectors are animals such as birds & bears that find an adequate diet on rangeland by carefully selecting berries, seeds, or roots low in cellulose

What is rangeland good for?

Water The Western United States has a much drier climate

than the Eastern U.S. ... water is doubly precious to the 30% of the U.S. population that lives in the West

Most of the water in the streams and river of Idaho fell initially on rangeland or forests. Therefore, proper management of rangeland requires careful attention to the amount & quality of water that flows off rangeland

What is rangeland good for?

RecreationRangelands are increasingly important for recreational uses such as: Hiking Hunting Camping Mountain biking Cross-country skiing Snowmobiling

Many national parks are located on rangelands

What is rangeland good for?

Open Space People in the west value open space Livestock ranches are becoming “working wilderness”

to maintain biodiversity and wildlife habitat quality Environmentally concerned citizens have paid

ranchers to maintain open space through scenic easements

Western Heritage Ranching is important to maintain the “Western

Image”

Multiple Use

Because rangelands have many important uses, most rangelands are managed under principles of multiple-use

Several uses or values of rangeland are managed simultaneously with care to avoid overuse or destruction of natural resources.

What is range management?

Range Management is the careful use and management of rangeland resources (plants, animals, soil, and water) to meet the needs and desires of society without damaging the resource.

The tricky part is that the “needs and desires of society” are continually changing.

Livestock production has always been important but, greater management emphasis is now being placed on wildlife management, recreation, & water production

The term that best describes range management is: INTEGRATED

Tools of range management?

Fences can be placed to control how a pasture is grazed and provide seasons or years of rest from grazing

The number of livestock can be increased or decreased to meet management objectives. Very heavy grazing may be required for some needs (e.g., weed control or water harvest) and light grazing is necessary for other purposes (e.g., improved water quality or forage for elk)

The proper use of rangeland is accomplished by several simple tools that must be continually monitored and adjusted.

Tools of range management?

The species of livestock to be grazed must be carefully selected because each species differs in the diet they select. For example, cows generally prefer grasses, goats consume

mostly shrubs, and sheep eat mixed diets of grasses, browse and forbs

And, different species of livestock also differ in type of terrain they use. For example, sheep can graze steeper slopes than cattle

Invasion of weeds on rangelands is a growing problem. Range managers often need to use weed control practices (such as fire, grazing, or herbicides) to reduce the growth of weeds and allow native plants to grow.

Fire is a natural force in nearly all rangeland ecosystems. For healthy rangelands, fires are often carefully set and controlled (by prescribed burning techniques). For example, in Southern Idaho, fire is often used to control the spread of sagebrush and encourage the growth of productive grasses.
