elephant in the room: Absentee landowner issues in conservation and land management

Journal Articles & Books
Dezembro, 2013

In this article, we provide a synthesis of the peer-reviewed literature and state and federal policies focused on absentee landowners of forestland, rangeland, or farmland in the U.S. The synthesis indicates absentee owners, as compared to those living on the land, appear to be much more likely to live in urban areas, are less dependent financially upon the land and much more likely to own land for amenity reasons than production purposes.

Profiteers of environmental change in the Swiss Alps: increase of thermophilous and generalist plants in wetland ecosystems within the last 10 years

Journal Articles & Books
Dezembro, 2012
Europa

It has been predicted that Europe will experience a rise in temperature of 2.2–5.3 °C within this century. This increase in temperature may lead to vegetation change along altitudinal gradients. To test whether vegetation composition has already changed in the recent decade due to current warming (and other concomitant environmental changes), we recorded plant species composition in 1995 and 2005/2006 in Swiss pre-alpine fen meadows (800–1,400 m a.s.l.).

Grassland Reserve Program: New opportunities to benefit grassland wildlife

Journal Articles & Books
Dezembro, 2005

The Grassland Reserve Program (GRP) was established by the 2002 Farm Bill to provide assistance to landowners in conserving and enhancing ecological value of grasslands while maintaining their suitability for grazing and other compatible uses. In response to long-term declines in grassland acreage and their associated benefits, approximately 524,000 acres have been enrolled since fiscal year 2003 in a variety of long-term rental agreements and easements. The program has proven popular with landowners.

Restoring longleaf pine (Pinus palustris Mill.) in loblolly pine (Pinus taeda L.) stands: Effects of restoration treatments on natural loblolly pine regeneration

Journal Articles & Books
Dezembro, 2011
Estados Unidos

Historical land use and management practices in the southeastern United States have resulted in the dominance of loblolly pine (Pinus taeda L.) on many upland sites that historically were occupied by longleaf pine (Pinus palustris Mill.). There is currently much interest in restoring high quality longleaf pine habitats to such areas, but managers may also desire the retention of some existing canopy trees to meet current conservation objectives. However, fast-growing natural loblolly pine regeneration may threaten the success of artificially regenerated longleaf pine seedlings.

New Governance Era: Implications for Collaborative Conservation and Adaptive Management in Department of the Interior Agencies

Journal Articles & Books
Dezembro, 2011
Estados Unidos

The U.S. Department of the Interior (DOI) manages one-fifth of the land in the United States, including public lands administered by the National Park Service, U.S. Fish and Wildlife Service, and Bureau of Land Management. Federal agencies have included public input in decision-making since the Administrative Procedure Act in 1946, with varying degrees of effectiveness. Recently, policy and reporting directives have broadened to include possibilities for collaborative conservation. Many disciplines are identifying this rise in collaboration as a new era of governance.

Potential environmental effects of pack stock on meadow ecosystems of the Sierra Nevada, USA

Journal Articles & Books
Dezembro, 2014
Estados Unidos

Pack and saddle stock, including, but not limited to domesticated horses, mules, and burros, are used to support commercial, private and administrative activities in the Sierra Nevada. The use of pack stock has become a contentious and litigious issue for land management agencies in the region inter alia due to concerns over effects on the environment.

priming potential of biochar products in relation to labile carbon contents and soil organic matter status

Journal Articles & Books
Dezembro, 2011

Recognition of biochar as a potential tool for long-term carbon sequestration with additional agronomic benefits is growing. However, the functionality of biochar in soil and the response of soils to biochar inputs are poorly understood. It has been suggested, for example, that biochar additions to soils could prime for the loss of native organic carbon, undermining its sequestration potential. This work examines the priming potential of biochar in the context of its own labile fraction and procedures for their assessment.

role of natural habitats in agricultural systems for bird conservation: the case of the threatened Lesser Grey Shrike

Journal Articles & Books
Dezembro, 2008
Europa

Birds of agricultural systems are one of the most threatened groups of birds in Europe mainly due to their sharp population decline in recent decades. Habitat intensification resulting from more productive agricultural practices has been proposed as a major cause for these declines. However, especially in some regions such as Eastern European and Mediterranean countries, little is known about the ultimate factors linked to habitat intensification that drive population declines for different species.

Assessing Soil Quality in a Semiarid Tropical Watershed Using a Geographic Information System

Journal Articles & Books
Dezembro, 2011
Índia

Subsistence agriculture under rainfed conditions and declining or stagnant yields on irrigated farmland has raised concerns about resource management and long-term sustainability in the subtropical, semiarid region of India. Soil quality assessment has been recognized as an important step toward understanding the effects of land management practices within an agricultural watershed. This study addressed the spatial variability of soil properties and their quality at the watershed level using geostatistical methods.
