New Rangeland Residents in Wyoming? A Survey of Exurban Landowners

Journal Articles & Books
Diciembre, 2011

Rapid conversion of rural land to exurban development and the ensuing impacts on natural resources have been well-documented, but information about exurban landowners is lacking. To address this knowledge gap, we surveyed exurban landowners in six Wyoming counties and documented demographic characteristics, motivations, knowledge, and attitudes about natural resources and land management. The overall response rate was 55.6%. Generally, respondents were of retirement age, had lived in Wyoming for about 13 yr, and were raised in areas with a population

Economic and Social Impacts of Wildfires and Invasive Plants in American Deserts: Lessons From the Great Basin

Journal Articles & Books
Diciembre, 2011

Research on the impacts of wildfire and invasive plants in rangelands has focused on biophysical rather than human dimensions of these environmental processes. We offer a synthetic perspective on economic and social aspects of wildfire and invasive plants in American deserts, focusing on the Great Basin because greater research attention has been given to the effects of cheatgrass expansion than to other desert wildfire/invasion cycles.

Image interpreter tool: An ArcGIS tool for estimating vegetation cover from high-resolution imagery

Journal Articles & Books
Diciembre, 2011

Land managers need increased temporal and spatial resolution of rangeland assessment and monitoring data. However, with flat or declining land management and monitoring agency budgets, such increases in sampling intensity are unlikely unless new methods can be developed that capture data of key rangeland indicators at a lower cost. Remote sensing techniques have shown promise for collecting plant community composition and ground cover data efficiently. However, many image analysis techniques require software and expertise not always available to field offices.

Causes and Effects of Gully Erosion on Agricultural Lands and the Environment

Journal Articles & Books
Diciembre, 2011
Irán

This study was aimed at assessing the causes of the gully erosion and its effects on the agricultural lands in the arid region of southeastern Iran. In this study, we have used geologic maps in scales of 1:50,000 and 1:250,000, aerial photographs on a scale of 1:20,000, field observation, and GPS (global positioning system).

Methods for improving rangelands in the Blacksea region of Turkey

Policy Papers & Briefs
Diciembre, 2008
Turquía

The objective of this study was to determine the most suitable method (or methods) to improve in the rangelands around Samsun-Turkey rangelands between 1993 and 1999. The 12 management treatments in this study included control, aeration, burning, herbicide application, fertilization, over-sowing, ploughing + resowing and a combination of all the treatments. A mixture of seeds consisting of alfalfa, sainfoin, smooth bromegrass, orchardgrass and blue wheatgrass was used for oversowing and in the ploughing + resowing plots.

Opportunities for fire and carbon on pastoral properties in the savanna rangelands: perspectives from the Indigenous Land Corporation and the Northern Territory Cattlemen’s Association

Journal Articles & Books
Diciembre, 2014
Australia

Understanding both the carbon dynamics within Australia’s northern savannas and the opportunities presented through diversification into carbon markets is of relevance to pastoral land managers both in Australia and globally. The Indigenous Land Corporation (ILC), through its role in assisting Indigenous people to acquire and manage land for cultural, social, environmental and economic benefits, has operated in the carbon market and is keen to continue working with its partners to explore the opportunities to develop and broaden this further.

Soil carbon and nitrogen across a chronosequence of woody plant expansion in North Dakota

Journal Articles & Books
Diciembre, 2010
América Septentrional

Woody plant expansion has been documented on grasslands worldwide as a result of overgrazing and fire suppression, but changes in ecosystem structure and function accompanying this phenomenon have yet to be extensively studied in the temperate semi-arid grasslands of North America. The primary objectives of this study were to determine the influence of woody plant expansion on soil carbon (C), soil nitrogen (N), and roots to a depth of 15 cm along a 42-year (1963-2005) chronosequence encompassing grassland, woodland, and transition zones in a northern Great Plains grassland.

Understanding Variability in Adaptive Capacity on Rangelands

Journal Articles & Books
Diciembre, 2013

The art and science of developing effective policies and practices to enhance sustainability and adapt to new climate conditions on rangelands and savannas are typically founded on addressing the “average” or “typical” resource user. However, this assumption is flawed since it does not appreciate the extent of diversity among resource users; it risks that strategies will be irrelevant for many people and ignored, and that the grazing resource itself will remain unprotected. Understanding social heterogeneity is vital for effective natural resource management.

Determinants of food security under changing land-use systems among pastoral and agro-pastoral households in eastern Ethiopia

Journal Articles & Books
Diciembre, 2015
Etiopía

A number of previous studies have emphasized the determinants of land-use change, as well as the management of communal lands in the pastoral systems, without assessing the effects of such changes on pastoralists/agro-pastoralists’ food security. Therefore, the objective of this paper was to assess the determinants of food security under changing land use and land management systems—from communal to private investment—using household survey data collected from pastoral and agro-pastoral communities. The data were analyzed using ordinary least-square econometric analysis.

Monitoring the status of forests and rangelands in the Western United States using ecosystem performance anomalies

Journal Articles & Books
Diciembre, 2013
Estados Unidos de América

The effects of land management and disturbance on ecosystem performance (i.e. biomass production) are often confounded by those of weather and site potential. The current study overcomes this issue by calculating the difference between actual and expected ecosystem performance (EEP) to generate ecosystem performance anomalies (EPA). This study aims to delineate and quantify average EPA from 2000–2009 within the Greater Platte and Upper Colorado River Basins, USA.

Soil seed bank evaluation along a degradation gradient in arid rangelands of the Somali region, eastern Ethiopia

Journal Articles & Books
Diciembre, 2009
Etiopía

The potential and regeneration capacity of soil seed banks in three eastern Ethiopian rangeland ecosystems (Asbuli grassland or arid grassland, Aydora open savanna or arid bush/grassland and Hurso closed savanna or arid bush land) were determined over a degradation gradient. Soil samples from 0.09m² blocks (100mm deep) were spread evenly in plastic containers in the greenhouse and studied over a 1-year period. The aboveground species composition was also compared. Sampling was from rangelands in excellent, good, moderate and poor conditions for each ecosystem.

Grazing impacts on the susceptibility of rangelands to wind erosion: The effects of stocking rate, stocking strategy and land condition

Journal Articles & Books
Diciembre, 2015
Australia

An estimated 110 Mt of dust is eroded by wind from the Australian land surface each year, most of which originates from the arid and semi-arid rangelands. Livestock production is thought to increase the susceptibility of the rangelands to wind erosion by reducing vegetation cover and modifying surface soil stability. However, research is yet to quantify the impacts of grazing land management on the erodibility of the Australian rangelands, or determine how these impacts vary among land types and over time.
