Rangeland management (also range management, range science, or arid-land management) is a natural science that centers around the study of rangelands and the "conservation and sustainable management [of Arid-Lands] for the benefit of current societies and future generations". [1] Range management is defined by Holechek et al. as the "manipulation of rangeland components to obtain optimum combination of goods and services for society on a sustained basis". [2] The United Nations (UN) has declared 2026 the International Year of Rangelands and Pastoralists, with the Food and Agriculture Organization leading the iniative. [3]

History

The earliest form of Rangeland Management is not formally deemed part of the natural science studied today, although its roots can be traced to nomadic grazing practices of the neolithic agricultural revolution when humans domesticated plants and animals under pressures from population growth and environmental change. [4] Humans might even have altered the environment in times preceding the Neolithic through hunting of large-game, whereby large losses of grazing herbivores could have resulted in altered ecological states; meaning humans have been inadvertently managing land throughout prehistory. [5] [6]

Rangeland management was developed in the United States in response to rangeland deterioration and in some cases, denudation, due to overgrazing and other misuse of arid lands as demonstrated by the 20th century "Dust Bowl" and described in Hardin's 1968 "Tragedy of the Commons". [7] [8] [9] Historically, the discipline focused on the manipulation of grazing and the proper use of rangeland vegetation for livestock. [10]

Global

Range management's focus has been expanded to include the host of ecosystem services that rangelands provide to humans world-wide. Key management components seek to optimize such goods and services through the protection and enhancement of soils, riparian zones, watersheds, and vegetation complexes, sustainably improving outputs of consumable range products such as red meat, wildlife, water, wood, fiber, leather, energy resource extraction, and outdoor recreation, as well as maintaining a focus on the manipulation of grazing activities of large herbivores to maintain or improve animal and plant production. [11] With increasing levels of rangeland degradation, for example as evident through woody plant encroachment, active rehabilitation efforts become part of rangeland management. [12]

Pastoralism has become a contemporary anthropological and ecological study as it faces many threats including fragmentation of land, conversion of rangeland into urban development, lack of grazing movement, impending threats on global diversity, damage to species with large terrain, decreases in shared public goods, decreased biological movements, threats of a "tragedy of enclosures", limitation of key resources, reduced biomass and invasive plant species growth. [13] Interest in contemporary pastoralist cultures like the Maasai has continued to increase, especially because the traditional syncreticly-adaptive ability of pastoralists could promise lessons in collaborative and adaptive management for contemporary pastoralist societies threatened by globalization as well as for contemporary non-pastoralist societies that are managing livestock on rangelands. [14] [15]

United States of America

The United States Society for Range Management is "the professional society dedicated to supporting persons who work with rangelands and have a commitment to their sustainable use". [16] The primary Rangeland Management publications include the Journal of Range Management, Rangelands, and Rangeland Ecology & Management. [17]

As climate change continues to disrupt a host of rangeland functions, [18] the Society for Range Management has declared that it "is committed to promoting adaptation to and mitigation of climate change through the sponsorship of workshops, symposia, research and educational publications, and appropriate policy recommendations. The Society will strive to maximize opportunities and minimize challenges posed by climate change to promote productive rangeland ecosystems that ensure food security, human livelihoods, and continued delivery of diverse ecosystem services"." [19] Emerging evidence suggests that rangelands are extremely vulnerable to the threats of climate change, [20] as more severe heatwaves, droughts, evaporation, and catastrophic flood events will consequentially alter ecological states, [21] and negatively affect forage production, [22] [23] both of which will negatively impact ecosystem functioning and the sustainable production of ecosystem services. In an open letter to the White House in 2017, the president of the SRM offered President Trump the society's support in seeking management strategies to mitigate climate-induced phenomenon like drought and forest fires, [24] a subject which was brought to the national debate stage and which has received significant push-back by Trump and his administration. [25] Likewise in 2021 the SRM and several other institutions sent an open letter to President Biden urging for more research and development funding to be provisioned toward agricultural and food systems research, especially as climate change threatened national security of agricultural resources. [26]

Australia

The Australian Rangeland Society is the peak group of rangeland professionals in Australia. It is an independent and non-aligned association of people interested in the management and sustainable use of rangelands. [27] Rangeland Management publications from the Society include The Rangeland Journal [28] and the Range Management Newsletter. [29]

In the United States, the study of range science is commonly offered at land-grant universities including New Mexico State University, Colorado State University, Oregon State University, North Dakota State University, South Dakota State University, Texas A&M University, Texas Tech University, the University of Arizona, the University of Idaho, the University of Wyoming, Utah State University, and Montana State University. [31] The Range Science curriculum is strongly tied to animal science, as well as plant ecology, soil science, wildlife management, climatology and anthropology. Courses in a typical Range Science curriculum may include ethology, range animal nutrition, plant physiology, plant ecology, plant identification, plant communities, microbiology, soil sciences, fire control, agricultural economics, wildlife ecology, ranch management, Socioeconomics, cartography, hydrology, Ecophysiology, and environmental policy. These courses are essential to entering a range science profession.

Students with degrees in range science are eligible for a host of technician-type careers working for the federal government under the Bureau of Land Management, the United States Fish and Wildlife Service, the Agricultural Research Service, the United States Environmental Protection Agency, the NRCS, or the US Forest Service as range conservationists, inventory technicians, range monitoring/animal science agents, field botanists, natural-resource technicians, vegetation/habitat monitors, GIS programming assistants, general range technicians, and as ecological assessors, as well as working in the private sector as range managers, ranch managers, producers, commercial consultants, mining and agricultural real estate agents, or as Range/ Ranch Consultants. Individuals who complete degrees at the M.S. or P.h.D. level, can seek academic careers as professors, extension specialists, research assistants, and adjunct staff, in addition to a number of professional research positions for government agencies such as the US Department of Agriculture and other state run departments.

A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area.

<span class="mw-page-title-main">Savanna</span> Mixed woodland-grassland ecosystem

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to Britannica, there exists four savanna forms; savanna woodland where trees and shrubs form a light canopy, tree savanna with scattered trees and shrubs, shrub savanna with distributed shrubs, and grass savanna where trees and shrubs are mostly nonexistent.

<span class="mw-page-title-main">Rotational grazing</span> System of grazing moving animals between paddocks around the year

In agriculture, rotational grazing, as opposed to continuous grazing, describes many systems of pasturing, whereby livestock are moved to portions of the pasture, called paddocks, while the other portions rest. Each paddock must provide all the needs of the livestock, such as food, water and sometimes shade and shelter. The approach often produces lower outputs than more intensive animal farming operations, but requires lower inputs, and therefore sometimes produces higher net farm income per animal.

<span class="mw-page-title-main">Grazing</span> Feeding livestock on forage

In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range and consume wild vegetations in order to convert the otherwise indigestible cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.

<span class="mw-page-title-main">Rangeland</span> Biomes which can be grazed by animals or livestock (grasslands, woodlands, prairies, etc)

Rangelands are grasslands, shrublands, woodlands, wetlands, and deserts that are grazed by domestic livestock or wild animals. Types of rangelands include tallgrass and shortgrass prairies, desert grasslands and shrublands, woodlands, savannas, chaparrals, steppes, and tundras. Rangelands do not include forests lacking grazable understory vegetation, barren desert, farmland, or land covered by solid rock, concrete and/or glaciers.

<span class="mw-page-title-main">Pastoralism</span> Branch of agriculture concerned with raising livestock

Pastoralism is a form of animal husbandry where domesticated animals are released onto large vegetated outdoor lands (pastures) for grazing, historically by nomadic people who moved around with their herds. The animal species involved include cattle, camels, goats, yaks, llamas, reindeer, horses, and sheep.

Adaptive management, also known as adaptive resource management or adaptive environmental assessment and management, is a structured, iterative process of robust decision making in the face of uncertainty, with an aim to reducing uncertainty over time via system monitoring. In this way, decision making simultaneously meets one or more resource management objectives and, either passively or actively, accrues information needed to improve future management. Adaptive management is a tool which should be used not only to change a system, but also to learn about the system. Because adaptive management is based on a learning process, it improves long-run management outcomes. The challenge in using the adaptive management approach lies in finding the correct balance between gaining knowledge to improve management in the future and achieving the best short-term outcome based on current knowledge. This approach has more recently been employed in implementing international development programs.

<span class="mw-page-title-main">Ecological restoration</span> Scientific study of renewing and restoring ecosystems

Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed. It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures. Ecological restoration can reverse biodiversity loss, combat climate change, and support local economies. Habitat restoration involves the deliberate rehabilitation of a specific area to reestablish a functional ecosystem. To achieve successful habitat restoration, it's essential to understand the life cycles and interactions of species, as well as the essential elements such as food, water, nutrients, space, and shelter needed to support species populations. When it's not feasible to restore habitats to their original size or state, designated areas known as wildlife corridors can be established. These corridors connect different habitats and open spaces, facilitating the survival of species within human-dominated landscapes. For instance, marshes serve as critical stopover sites for migratory birds, wildlife overpasses enable animals to safely cross over highways, and protected riparian zones within urban settings provide necessary refuges for flora and fauna. The United Nations named 2021-2030 the Decade on Ecosystem Restoration.

Regime shifts are large, abrupt, persistent changes in the structure and function of ecosystems, the climate, financial systems or other complex systems. A regime is a characteristic behaviour of a system which is maintained by mutually reinforced processes or feedbacks. Regimes are considered persistent relative to the time period over which the shift occurs. The change of regimes, or the shift, usually occurs when a smooth change in an internal process (feedback) or a single disturbance triggers a completely different system behavior. Although such non-linear changes have been widely studied in different disciplines ranging from atoms to climate dynamics, regime shifts have gained importance in ecology because they can substantially affect the flow of ecosystem services that societies rely upon, such as provision of food, clean water or climate regulation. Moreover, regime shift occurrence is expected to increase as human influence on the planet increases – the Anthropocene – including current trends on human induced climate change and biodiversity loss. When regime shifts are associated with a critical or bifurcation point, they may also be referred to as critical transitions.

<span class="mw-page-title-main">Forest restoration</span>

Forest restoration is defined as "actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest", i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans. Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Additionally, the potential impacts of climate change on restoration goals must be taken into account, as changes in temperature and precipitation patterns may alter the composition and distribution of climax forests.

Holistic Management in agriculture is an approach to managing resources that was originally developed by Allan Savory for grazing management., Holistic Management has been likened to "a permaculture approach to rangeland management". Holistic Management is a registered trademark of Holistic Management International. It has faced criticism from many researchers who argue it is unable to provide the benefits claimed.

Dr. Margaret Hilda Friedel is an Australian rangeland ecology and management researcher, widely cited nationally and internationally for her work on the concept of ecosystem thresholds and her collaborative research with landholders and communities in outback Australia to foster understanding of the nature of rangeland ecosystems and how to balance commercial production with maintenance of a fragile resource base.

<span class="mw-page-title-main">Woody plant encroachment</span> Vegetation cover change

Woody plant encroachment is a natural phenomenon characterised by the increase in density of woody plants, bushes and shrubs, at the expense of the herbaceous layer, grasses and forbs. It predominantly occurs in grasslands, savannas and woodlands and can cause regime shifts from open grasslands and savannas to closed woodlands. The term bush encroachment refers to the expansion of native plants and not the spread of alien invasive species. It is thus defined by plant density, not species. Woody encroachment is often considered interpreted as a symptom of land degradation. The phenomenon is observed across different ecosystems and with different characteristics and intensities globally.
