Thousands of years BP
Native Americans inhabit the region we define as Oregon today.

Mid 1700s
Horses are introduced into present-day Oregon.

1804-1806
Captains Lewis and Clark travel with their party from Missouri to the mouth of the Columbia River.

1800s
Oregons streams, rivers, and lakes teem with beaver, and commerce in beaver pelts attracts explorers, trappers, and traders to the region.

1811
Astoria is established by the Pacific Fur Company. Hogs and sheep are brought to Oregon on the Tonquin by the Astor party.

1824-1825
Hudsons Bay Company imports cattle and sheep by ship from California.

Until this time, some authorities ban the butchering of cattle to allow herds to increase in size.

1838
The first cattle drive of the West arrives in Oregon from California.

1840s
The Willamette Valley receives cattle from the California surplus. Farming and stockraising with Andalusian blacks supplants the fur economy in the Willamette Valley.

Civil government is established in the Oregon Country. Major immigration to Oregon occurs along the Oregon Trail.

1844
Joshua Shaw and son are the first to bring sheep across the plains.

1846
High-bred shorthorns, or Durhams, are introduced by settlers over the Oregon Trail. These cattle are the forerunners of the dairy and domestic livestock industries.

1848
The Oregon Territory is organized. Gold is discovered in California.

Joseph Watt brings high-grade sheep over the Oregon Trail.

1851-1852
Gold is found along Jackson Creek in southern Oregon.

1853
Joel Palmer becomes superintendent of Indian affairs; he later initiates the reservation system in Oregon in an effort to protect the natives.

1850s
Up until this time, millions of buffalo roam the plains from West Virginia to present-day Oregon.

1857
The first woolen mill on the Pacific Coast opens in Salem.

1859
Congress ratifies the Oregon State Constitution, and the state accepts the congressional proposal to be admitted to the Union.

1860s
Sheep in western Oregon are displaced in favor of wheat. Cattle drives begin across the Cascades to the Willamette Valley. The number of sheep and cattle increase with settlement in central and eastern Oregon.

1862
Congress passes the Homestead Act, allowing 160 acres to those who would live on and work the land. This acreage was not as economically viable in the western states, with more limited rainfall, as in the East.

Gold is discovered in eastern Oregon, in Baker and Grant counties.

18631864
Large herds of Durhams and some Moors are moved from the Willamette Valley to feed miners in eastern Oregon and southern Idaho. Sheep are brought into Jordan Valley, with cattle soon to follow.

1865
The number of sheep exceeds the demand of the woolen mills.

1866-1890
Herds of buffalo are destroyed. Massive migration of Texas longhorns occurs northward. The open range system develops, and branding is used to distinguish among cattle on unenclosed land. The technique of stock farmingwith enclosures, winter feed, and controlled breedingspreads from the Midwest to the Willamette Valley.

1869
Chicago and San Francisco are connected by rail.

Oregon livestock are driven to Winnemucca for shipment in either direction. Northern California surplus cattle are moved into southeastern Oregon. Texas longhorns expand these herds.

1870
The state takes title to swamplands granted by the federal government at time of statehood, and begins selling them. They provide excellent grazing land.

1872
Peter French arrives in southeastern Oregon and soon manages the P Ranch and the Diamond Ranch.

1873
The ranges teem with cattle. The first West to East cattle drive for stocking is made.

1874

1885
The Unlawful Enclosures Act forbids excluding other users of public domain lands with illegal fences or intimidation, which have become common practices.

1886-1887
Thousands of animals die on depleted rangelands during severe winter conditions.

1900
Farmers and sheep-growers provide increasing competition to cattle ranchers. The railroad makes Shaniko one of the worlds principal wool markets.

Rail lines extend into Prineville, Lakeview, and later Redmond, Burns, and Bend, all of which become active cow and sheep towns.

Early 1900s
Range wars occur between cattle and sheep growers, e.g., in Baker, Crook, and Lake counties.

1906
A Forest Service regulatory program requires a permit and a fee for grazing on public lands within the national forests. Grazing is possible on two-thirds of national forest land, one-third of which is open rangeland.

1917
The United States enters World War I.

Demand for meat increases and promotes industry expansion.

1929
The Great Depression begins.

Overgrazed lands impacted by prolonged drought cannot sustain the numbers of animals grazing on them.

1930s
The woolen mills decline. Sheep are most prominent in southeastern Oregon. Some public lands are already permanently damaged by overgrazing.

1934
The remaining public domain is withdrawn from homesteading. The Taylor Grazing Act institutes federal protection and management of these lands; today the act guides the activities of the USDI Bureau of Land Management.

1941
The United States enters World War II.

1946
The agency established as the Grazing Service merges with the General Land Office to form the USDI Bureau of Land Management.

1950-1978
Beef cattle increase in Oregon, and dairy cows and sheep decline.

1970
The National Environmental Policy Act is enacted.

1973
Statewide land use planning is approved. Congress passes the Endangered Species Act.

1977
The cattle feeding business is a major enterprise. Cattle supplant sheep in eastern Oregon. Sheep occur in greater numbers west of the Cascades, with the majority in the southern Willamette Valley on irrigated pasture or year-round pasture at the coast.

1976
The Federal Land Policy and Management Act requires that public lands be retained in federal ownership.

1978
The Public Rangeland Improvement Act gives range improvement highest management priority, and stock reductions are initiated.

1979 The McClure Amendment requires a two-year phase-in period for stock reductions greater than 10%.

Early 1980s
A coalition of ranchers, miners, loggers, developers, farmers, and others create the Sagebrush Rebellion and argue for more local control over land management and natural resources. Ranching interests maintain grazing fees below market value.

1987
In Oregon, 1,503,630 cattle and calves are worth $431,728,000, and 470,290 sheep and lambs are worth $37,448,000. The 95,330 milk cows in the state produce $179,169,000 in dairy products.

Present
Most Oregon sheep are raised in farm flocks in western Oregon. Cattle and calves rank as the states number one agricultural commodity. The most extensive herds occur in central, southeastern, and northeastern Oregon2.
