Method For Landscape-Scale Vegetation Assessment: Application to Great Basin Rangeland Ecosystems

Journal Articles & Books
December, 2007
United States of America

The growth of landscape-scale land management necessitates the development of methods for large-scale vegetation assessment. Field data collection and analysis methods used to assess ecological condition for the 47165-h North Spring Valley watershed are presented. Vegetation cover data were collected in a stratified random design within 6 Great Basin vegetation types, and the probability of detecting change in native herbaceous cover was calculated using power analyses.

Changes in the fragmentation and ecological stability of the Morava River floodplain forest in the course of the 20th century

Policy Papers & Briefs
March, 2009
Czech Republic

This paper presents the results of an analysis of the changes in the fragmentation and ecological stability of the floodplain forest geobiocoenoses in the Protected Landscape Area Litovelske Pomoravi, Czech Republic. Using GIS methods, it was determined that the fragmentation within the study area had increased slightly and the ecological stability of the landscape had decreased slightly between the years 1938 and 2006, although the latter remained on a fairly high level.

Delineation and functional status monitoring in small saline wetlands of NE Spain

Journal Articles & Books
December, 2009

The small playa-lakes and other saline wetlands of Monegros, scattered over a dry area with winter cereal monoculture, are threatened by the settlement of new irrigation districts and other kinds of human pressure. Enforcing the protection rules of European Union in these valuable habitats requires, first, their delimitation and monitoring. This article shows how these tasks can be undertaken using remote sensing in conjunction with field observations.

Labile nitrogen, carbon, and phosphorus pools and nitrogen mineralization and immobilization rates at low temperatures in seasonally snow-covered soils

Journal Articles & Books
December, 2007

Surface mineral horizons from four ecosystems sampled in the northwestern Italian Alps were incubated at -3 and +3°C to simulate subnivial and early thaw period temperatures for a seasonally snow-covered area. The soil profiles at these sites represent extreme examples of management, grazed meadow (site M) and extensive grazing beneath larch (site L) or naturally disturbed by avalanche and colonized by alder (site A) and the expected forest climax vegetation beneath fir (site F).

Linkages between land management activities and stream water quality in a border dyke-irrigated pastoral catchment

Journal Articles & Books
December, 2009
New Zealand

This paper describes key linkages between land management activities and stream water quality for a 5230ha catchment used for intensive pastoral agriculture in southern New Zealand. Due to low annual rainfall and the wide coverage of soils with low available water-holding capacities, flood irrigation of the 2400ha of flat land within the catchment is an important feature impacting on farm business profitability and stream health. Water quality variables and nutrient and sediment yield estimates are reported for a four-year period.

[Special features and economic principles of assessing a land plot]

Policy Papers & Briefs
December, 2009
Ukraine

The specificity and uniqueness of land as a land appraisal object are disclosed. Principles of land appraisal are considered, their interrelation and dependence on land use features are shown.

Розкрито специфіку і унікальність землі як обєкта оцінки. Розглянуті принципи оцінки земельних ділянок, показаний їх взаємозвязок і залежність від особливостей використання землі.

Contribution of Traditional Knowledge to Ecological Restoration: Practices and Applications

Journal Articles & Books
December, 2012

Traditional knowledge has become a topic of considerable interest within the research and development environment. The contribution of traditional knowledge to conservation and management is increasingly recognized, and implementation endeavours are underway in several countries. The current scale of ecosystem degradation underscores the need for restoration interventions. It is increasingly recognized that successful ecological restoration depends on effective coordination of science and traditional ecological knowledge.

Methodical approaches to the improvement of the use of lands and organization of the territory of agricultural organizations in conditions of ecologization of land use

Policy Papers & Briefs
December, 2012
Belarus

In the conditions of the Republic of Belarus there were presented theoretical statements and methodical approaches to the improvement of the use of lands and organization of the territory of agricultural organizations in conditions of ecologization of land use. There were formulated the notion and tasks of improvement of the use of lands of agricultural organizations.

Fire resistance of tree species explains historical gallery forest community composition

Journal Articles & Books
December, 2011
United States of America
Northern America

Fire, climatic variability, and grazing by large herbivores have historically limited woody vegetation in the tallgrass prairie region of North America to gallery forests in protected areas along rivers and streams. Fire, in particular, has been a strong selective pressure against woody vegetation. Consequently, we expect that dominant tree species in these forests have developed mechanisms for tolerating periodic surface fires.

Different approaches to the social vision of communal land management: the case of Galicia (Spain)

Journal Articles & Books
September, 2010
Spain

Communal forests, or Montes Veciñais en Man Común (MVMC), are a specific form of communal land tenure and a singular legal category in Galicia. The growing demographic decline in rural areas and, particularly, in inner areas of Galicia has led to a decrease in the economic interest of forest resources. The complexity of the different management modes or levels of organization of forest communities cannot be explained through a homogeneous interpretation.

Drivers of songbird productivity at a restored gravel pit: Influence of seasonal flooding and rainfall patterns and implications for habitat management

Journal Articles & Books
December, 2012

The restoration of riparian sites following aggregate extraction frequently aims to expand the wetland habitat, and enhance the wetland wildlife community. However, aggregate extraction sites, typically on river flood plains, are subject to unpredictable flooding along with climate variability and other factors beyond the control of local management that may be equally important in determining the success or failure of a restoration project.
