Evidence of sustainable intensification among British farms

Journal Articles & Books
Décembre, 2013

Several influential reports have suggested that one of the most appropriate responses to expected food shortages and ongoing environmental degradation is sustainable intensification, i.e. the increase of food production with at worst no increase in environmental harm, and ideally environmental benefit. Here we sought evidence of sustainable intensification among British farmers by selecting innovative arable, dairy, mixed and upland farms and analysing their own data on yields, inputs and land use and management for 2006 and 2011.

Hardwood Rangeland Landowners in California from 1985 to 2004: Production, Ecosystem Services, and Permanence

Journal Articles & Books
Décembre, 2010

A longitudinal study of California hardwood rangelands shows significant change in landowner characteristics and goals. Results of three studies spanning 1985 to 2004 were used to develop and evaluate a multiagency research and extension program known as the Integrated Hardwood Range Management Program. Program-sponsored education and research aimed at encouraging landowners to change woodland management has been reflected in a significant reduction in oak cutting and an increase in oak planting.

Early Decomposition of Ashe Juniper (Juniperus ashei) Wood in Open and Shaded Habitat

Journal Articles & Books
Décembre, 2010

Grasslands of the Edwards Plateau of central Texas have been extensively altered through woody species encroachment, particularly as a result of increasing abundance of the invasive native shrub, Ashe juniper (Juniperus ashei). Over the last several decades there has been widespread mechanical removal of the species. The wood is often left in place to decompose, either mulched or not. Where the wood is left to decompose might have some bearing on its rate of decomposition. This study was conducted to determine the rates of Ashe juniper wood decomposition as a function of open vs.

Habitat use by elk (cervus elaphus) within structural stages of a managed forest of the northcentral United States

Timber management is the most prominent land management activity in the Black Hills National Forest in the northcentral United States. Management units are stands 4–32ha in size and are described using a hierarchal vegetative description including vegetation type, size class (age), and overstory canopy cover. For the most part, these stands are relatively homogeneous resulting from decades of even-aged management.

Conservation begins after breakfast: The relative importance of opportunity cost and identity in shaping private landholder participation in conservation

Journal Articles & Books
Décembre, 2013

The conservation opportunity literature increasingly emphasises opportunity cost as an important determinant of willingness to engage in conservation on private land. We investigated the explanatory power of a group of opportunity cost variables in the decision to participate in a landscape-level conservation initiative on the Agulhas Plain, Cape Floristic Region. Opportunity cost variables outperformed affiliation and demographic variables when used in one model and had almost as much explanatory power as the combined model when used on their own.

Effects of grazing and experimental warming on DOC concentrations in the soil solution on the Qinghai-Tibet plateau

Journal Articles & Books
Décembre, 2009

Little information is available about the effects of global warming and land management on dissolved organic carbon (DOC) concentration in soil solution in the field. Here, for the first time, we used a free-air temperature enhancement (FATE) system in a controlled warming-grazing experiment in 2006 and 2007 to test the hypothesis that grazing modifies the response of soil solution DOC concentration to experimental warming.

Use of GIS to Prioritize Cogongrass (Imperata cylindrica) Control on Camp Shelby Joint Forces Training Center, Mississippi

Journal Articles & Books
Décembre, 2009

Geographic information systems (GIS) analysis considering size and spatial distribution of infestations of invasive species on a landbase can assist with developing appropriate control strategies for that species. We used GIS to evaluate strategies that placed highest priority on: smallest patches of cogongrass, largest patches of cogongrass, and cogongrass patches on land considered high-value under military training and conservation priorities on Camp Shelby Joint Forces Training Center (CSJFTC), MS.

Herbicide Evaluation to Control Clematis terniflora Invading Natural Areas in Gainesville, Florida

Japanese clematis, a herbaceous to woody vine native to Asia, has been widely used for landscaping in the southeastern United States and is now a naturalized and invasive in Florida. Herbicides that contain the active ingredients fluroxypyr, glyphosate, imazapic, metsulfuron, or triclopyr, applied alone or in combination on a spray-to-wet basis, were evaluated for their effectiveness to control the plant in a natural area of Gainesville, FL. All herbicide treatments provided some level of control 30, 60, and 90 d after application.

Community stakeholders’ knowledge in landscape assessments – Mapping indicators for landscape services

Journal Articles & Books
Décembre, 2012
Tanzania

The evaluation of landscape services essentially deals with the complex and dynamic relationships between humans and their environment. When it comes to landscape management and the evaluation of the benefits these services provide for our well-being, there is a limited representation of stakeholder and intangible values on the land. Stakeholder knowledge is essential, since disciplinary expert evaluations and existing proxy data on landscape services can reveal little of the landscape benefits to the local stakeholders.

Informing conservation policy design through an examination of landholder preferences: A case study of scattered tree conservation in Australia

Journal Articles & Books
Décembre, 2012
Australie

Choosing effective policy instruments to achieve conservation goals has many challenges. We explore the challenge of instrument choice in the context of landscape-scale conservation on private land, where the challenge is to select instruments that are able to influence the management practices of large numbers of landholders with diverse values, beliefs and management priorities. We report on a landholder survey and workshop undertaken as part of a study focused on reversing scattered tree decline on private grazing land in Australia.

Perceptions of Landowners Concerning Conservation, Grazing, Fire, and Eastern Redcedar Management in Tallgrass Prairie

Journal Articles & Books
Décembre, 2010

Successful prairie restoration will depend in part on convincing private landowners with agricultural and recreational use goals to implement appropriate rangeland management practices, such as prescribed burning and cattle grazing, to control invasive species and encroachment of woody plants. However, landowners have been slow to adopt appropriate practices in the US Midwest. The purpose of this study was to explore attitudes and behaviors of private landowners toward prescribed burning and moderate stocking as rangeland management tools.
