Open range

Open range is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Open range rather than just read about it. In short: In the Western United States and Canada, open range is rangeland where cattle roam freely regardless of land ownership. Where there are "open range" laws, those wanting to keep animals off their property must erect a fence to keep animals out; this applies to public roads as well.

Key takeaways

  • Open range belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Open range to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Open range from memory before moving on to harder problems.

Reference excerpt

In the Western United States and Canada, open range is rangeland where cattle roam freely regardless of land ownership. Where there are "open range" laws, those wanting to keep animals off their property must erect a fence to keep animals out; this applies to public roads as well. Land in open range that is designated as part of a "herd district" reverses liabilities, requiring an animal's owner to fence it in or otherwise keep it on the person's own property. Most eastern states and jurisdictions in Canada require owners to fence in or herd their livestock.

History and practice

The Western open-range tradition originated from the early practice of unregulated grazing of livestock in the newly acquired western territories of the United States and Canada. These practices were eventually codified in the laws of many Western US states as they developed written statutes. Over time, as the Western lands became more populated and more developed (through railroads, mining, farming, etc.), open-range laws began to be challenged and were significantly curtailed, though they still exist in certain areas of most Western US states and Canadian provinces. Open-range conditions existed in Western Canada prior to the 1889 amendments of the Dominion Lands Act, which prohibited cattle from grazing on unleased land, though the practice did not disappear immediately. Open-range management has also been practiced in other areas, including the Caribbean and some Eastern US states, such as South Carolina during the colonial period. The practice was also widespread in Mexico, and some argue that the Mexican tradition may have been the predecessor to open-range practices in the American West, much of which was part of Mexico prior to the 1840s. American ranchers borrowed many other cattle-raising techniques from Mexico. Unlike the Eastern United States, the Western prairies of the 19th century were vast, undeveloped, and uncultivated. The land was also generally much more arid, with scarce, widely separated sources of water. Until the invention of barbed wire in the 1870s, it was more practical to fence the livestock out of developed land, rather than to fence it in. As the United States government acquired Western territories by purchasing, conquest, and treaty, land not yet placed into private ownership was publicly owned and freely available for grazing cattle, though conflicting land-claims and periodic warfare with Native Americans placed some practical limits on grazing areas at various times. Free-roaming range cattle were calved, moved between grazing lands, and driven to market by cowboys. Brands on cattle marked who owned them. Unbranded cattle, known as "mavericks", could become the property of anyone able to capture and brand them. The invention of barbed wire in the 1870s made it easier to confine cattle to designated areas, which helped to prevent overgrazing of the range, and made fencing huge expanses cheaper than hiring cowboys to handle cattle. In Texas and surrounding areas, rapid population growth required ranchers to fence off their lands. This initially brought considerable drama to the Western rangelands. Indiscriminate fencing of federal lands was commonplace in the 1880s, often without any regard to land ownership or other public needs, such as mail delivery and movement of other kinds of livestock. Various state statutes, as well as vigilantism during the so-called Fence Cutting Wars, tried to enforce or combat fence-building, with varying success. In 1885 U.S. federal legislation outlawed the enclosure of public land. By 1890 illegal fencing had been mostly removed. In the north, overgrazing stressed the open range, leading to insufficient winter forage for cattle and their subsequent starvation, particularly during the harsh winter of 1886–1887, when severely overgrazed rangelands combined with unusually cold temperatures killed hundreds of thousands of cattle. This was called the Big Die-Up by ranchers and across the northern plains, led to the sudden collapse of the cattle industry. By the 1890s, barbed-wire fencing had become standard on the northern plains, railroads had expanded to cover most of the U.S., and meatpacking plants were being built closer to major ranching areas, making long cattle drives from Texas to the railheads in Kansas unnecessary. The age of the open range was over and large cattle-drives were no more. At the same time, independently-owned ranches multiplied all over the developing West.

Worked examples

Example 1 — a first encounter with Open range

Start with the simplest possible case. Write down what Open range claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Open range before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Open range ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Open range

In research
Open range appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Open range in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Open range is common in secondary-school and first-year university syllabi. It links to neighbouring topics American frontier, Cattle, Grasslands, so understanding it makes those chapters shorter.
In everyday life
Look for Open range outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Open range in simple terms?

In the Western United States and Canada, open range is rangeland where cattle roam freely regardless of land ownership. Where there are "open range" laws, those wanting to keep animals off their property must erect a fence to keep animals out; this applies to public roads as well.

Why does Open range matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Open range?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
