Herbicide Control Strategies for Ventenata dubia in the Intermountain Pacific Northwest

Journal Articles & Books
Diciembre, 2016

Ventenata dubia is an exotic annual grass that has become increasingly invasive in various perennial grass systems throughout the Intermountain Pacific Northwest. Currently, little information is available to landowners about herbicide control options. In our first field study, we evaluated V. dubia control efficacy and perennial grass tolerance of herbicides applied pre-emergence (PRE) at two locations and as an early postemergence (EPOST) application at four different conservation reserve grasslands, with each grassland dominated by different perennial grass species.

Managing Sources and Sinks of Greenhouse Gases in Australia's Rangelands and Tropical Savannas

Journal Articles & Books
Diciembre, 2010
Australia

Rangelands and savannas occupy 70% of the Australian continent and are mainly used for commercial grazing of sheep and cattle. In the center and north, where there are extensive areas of indigenous land ownership and pastoral production is less intensive, savanna burning is frequent. Greenhouse gas emissions from rangelands have been overwhelmingly from land clearing and methane production by livestock.

Benefits Derived from Rehabilitating a Degraded Semi‐Arid Rangeland in Private Enclosures in West Pokot County, Kenya

Journal Articles & Books
Diciembre, 2016
Kenya

Rehabilitating degraded rangelands using enclosures offers various benefits to agro‐pastoral households. However, enclosure benefits cannot be generalized as there are variations across dryland ecosystems and societies. This study assessed the qualitative and quantitative benefits derived from rehabilitating degraded rangelands using private enclosures in Chepareria, West Pokot County, Kenya.

Consider the source: The impact of media and authority in outreach to private forest and rangeland owners

Journal Articles & Books

Estados Unidos de América

Over half of the United States is privately owned. Improving environmental sustainability requires that the scientific and management communities provide effective outreach to the many landowners making decisions about land use and management practices on these lands. We surveyed California forest and rangeland owners in ten counties throughout the state to assess the impact of existing outreach and identify gaps in information distribution and content.

Northern Great Basin: A Region of Continual Change

Journal Articles & Books
Diciembre, 2015

There are many controversies and conflicts surrounding land management in the Great Basin. The conflicts often revolve around the maintenance of native plant and animal communities. This paper outlines some of the historical aspects of plant community change and some of the unanticipated impacts of policies applied to the Great Basin during Euro-American exploration and settlement. This narrative provides readers with some background on the turbulent history of the Great Basin, and suggests the need for a coordinated vision for future Great Basin land management.

integrated modeling approach for estimating the water quality benefits of conservation practices at the River Basin Scale

Estados Unidos de América

The USDA initiated the Conservation Effects Assessment Project (CEAP) to quantify the environmental benefits of conservation practices at regional and national scales. For this assessment, a sampling and modeling approach is used. This paper provides a technical overview of the modeling approach used in CEAP cropland assessment to estimate the off-site water quality benefits of conservation practices using the Ohio River Basin (ORB) as an example.

Understanding transportation-caused rangeland damage in Mongolia

Mongolia

Mongolia, a vast and sparsely populated semi-arid country, has very little formal road infrastructure. Since the 1990s, private ownership and usage of vehicles has been increasing, which has created a web of dirt track corridors due to the communal land tenure and unobstructed terrain, with some of these corridors reaching over 4 km in width. This practice aids wind- and water-aided erosion and desertification, causing enormous negative environmental effects.

role of prescribed burn associations in the application of prescribed fires in rangeland ecosystems

Journal Articles & Books
Diciembre, 2014

Although the ecological thresholds for restoring fire-adapted ecosystems back to their original state are better understood than in the past, the key hurdle to reintroducing historical fire regimes at landscape scales is a social one. The objectives of this study were to assess the human dimensions of prescribed fire and evaluate the role of Prescribed Burn Associations (PBAs) in promoting the adoption of prescribed fire at the landscape scale. The study was conducted in 12 counties in Texas, consisting of clusters of four counties in each of three ecoregions.

Soil water repellency in rangelands of Extremadura (Spain) and its relationship with land management

Journal Articles & Books
Diciembre, 2013
España

Soil water repellency reduces infiltration capacity, enhancing overland flow and even runoff production, and may produce patchiness in water infiltration at the hillslope scale. Knowledge about hydrophobicity in rangelands of Mediterranean type climate and its relation with vegetation cover and land management is sparse. The objectives of the present work are to determine the degree and spatial occurrence of soil water repellency and to define its relationship with site characteristics, such as soil, vegetation and land management in rangelands of SW Spain.
