Mapping Changes in Land Cover Composition and Pattern for Comparing Mediterranean Rangeland Restoration Alternatives

Journal Articles & Books
December, 2016

The limited amount of studies addressing the long‐term effectiveness of restoration actions to combat land degradation is a constraint for current landscape restoration planning and implementation. Remote sensing data provide a unique opportunity for gathering information on the spatial and temporal variability of restoration processes and may contribute to fill this knowledge gap.

Differences in Net Primary Productivity Among Contrasting Habitats in Artemisia ordosica Rangeland of Northern China

Journal Articles & Books
December, 2009
China

Artemisia ordosica Krasch. is a semishrub native to the Ordos Plateau of Inner Mongolia, northern China, and forms a unique and dominant vegetation type in the sandland of the region. To determine the variation of productivity in A. ordosica rangeland, we investigated net primary production (NPP), fine root turnover, soil microbial C (Cmic), and soil organic carbon density (SOCd) on sand dunes differing in mobility (i.e., fixed, semifixed, and shifting sand dunes) in Mu Us sandland.

Biohydrologic effects of eastern redcedar encroachment into grassland, Oklahoma, USA

Journal Articles & Books
December, 2013
United States of America

Woody encroachment affects the biohydrology of rangelands worldwide and can increase evapotranspiration by increasing plant rooting depth, increasing the duration of the growing season, or by initiating a process of hydrologic recovery in formerly overgrazed landscapes. Eastern redcedar (Juniperus virginiana) is encroaching rapidly into rangelands in the Southern Great Plains of the USA, and beyond, including Oklahoma. However, the degree to which increasing growing season duration causes higher evapotranspiration after encroachment is not known.

politics of conservation in contemporary rural China

Journal Articles & Books
December, 2013
China

Placing conservation within a broad framework of agrarian and environmental politics, this review article argues that natural resource governance is fundamental to rural politics in China. Much of the environmental literature adopts a technocratic approach, ignoring the political nature of the redistribution of access to and control over natural resources, and of knowledge vis-à-vis degradation.

Sequestering carbon in soils of agro-ecosystems

Journal Articles & Books
December, 2011

Soils of the world’s agroecosystems (croplands, grazing lands, rangelands) are depleted of their soil organic carbon (SOC) pool by 25–75% depending on climate, soil type, and historic management. The magnitude of loss may be 10 to 50tonsC/ha. Soils with severe depletion of their SOC pool have low agronomic yield and low use efficiency of added input.

Avifauna trends following changes in a Mediterranean upland pastoral system

Journal Articles & Books
December, 2010
Europe

Understanding the relationships between biodiversity and land-use is a key element for the development of effective conservation strategies. We studied a mid-altitude steppe-like area of Southern France, the Causse de Sauveterre, that has been grazed for many centuries. The decrease of human population during the 20th century, particularly since the end of 2nd World War, and the ongoing changes in agricultural practices may have dramatic effects on many biodiversity components of these landscapes.

Rain Use Efficiency, Primary Production and Rainfall Relationships in Desert Rangelands of Tunisia

Journal Articles & Books
December, 2016
Tunisia

Desert rangelands are characterised by low and highly variable rainfall regime, low forage production and high heterogeneity in the distribution of natural resources. This study was carried out in the desert rangelands of Tunisia to evaluate the response of different rangelands to annual rainfall in terms of aboveground net primary production (ANPP) and rain use efficiency over a 10‐year period (2003–2012). In general, ANPP values were relatively low (123 kg DM ha⁻¹ y⁻¹) but would tend to increase with increasing annual rainfall for all rangeland types.

Mountain pastoralism in transition: Consequences of legalizing Cordyceps collection on yak farming practices in Bhutan

Journal Articles & Books
December, 2015
Bhutan

Yak farming is the main livelihood source for the high altitude communities in the eastern Himalaya. With increasing access to modern facilities, market opportunities and changes in the legal framework, pastoral systems in the Himalaya are undergoing an unprecedented change. Questionnaire-based qualitative surveys were conducted in five villages of northern Bhutan, to understand how the recent changes in the legal framework for Cordyceps (known as caterpillar fungus) collection have caused specific changes in yak farming practices.

Shrub control by browsing: Targeting adult plants

Journal Articles & Books
December, 2016

Reconciling the well known benefits of shrubs for forage with environmental goals, whilst preventing their dominance, is a major challenge in rangeland management. Browsing may be an economical solution for shrubby rangelands as herbivore browsing has been shown to control juvenile shrub growth. Less convincing results have been obtained for adult plants, and long-term experiments are required to investigate the cumulative effects on adult plants.

No longer tracking greenery in high altitudes: Pastoral practices of Rupshu nomads and their implications for biodiversity conservation

Journal Articles & Books
December, 2013
India
Asia

Nomadic pastoralism has thrived in Asia’s rangelands for several millennia by tracking seasonal changes in forage productivity and coping with a harsh climate. This pastoralist lifestyle, however, has come under intense transformations in recent decades due to socio-political and land use changes. One example is of the high-altitude trans-Himalayan rangelands of the Jammu and Kashmir State in northern India: major socio-political reorganisation over the last five decades has significantly impacted the traditional pasture use pattern and resources.

Limitations to Postfire Seedling Establishment: The Role of Seeding Technology, Water Availability, and Invasive Plant Abundance

Journal Articles & Books
December, 2010

Seeding rangeland following wildfire is a central tool managers use to stabilize soils and inhibit the spread of invasive plants. Rates of successful seeding on arid rangeland, however, are low. The objective of this study was to determine the degree to which water availability, invasive plant abundance, and seeding technology influence postfire seedling establishment. Across four fire complexes, whole plots were either seeded using a rangeland drill, seeded by hand where seeds could be placed at an exact depth, or left as unseeded controls.

Vegetation Characteristics of Mountain and Wyoming Big Sagebrush Plant Communities in the Northern Great Basin

Journal Articles & Books
December, 2010
United States of America

Dominant plant species are often used as indicators of site potential in forest and rangelands. However, subspecies of dominant vegetation often indicate different site characteristics and, therefore, may be more useful indicators of plant community potential and provide more precise information for management. Big sagebrush (Artemisia tridentata Nutt.) occurs across large expanses of the western United States.
