Response of soil microbial and invertebrate communities to tracked vehicle disturbance in tallgrass prairie

Journal Articles & Books
Diciembre, 2009

Soil biota drive fundamental ecosystem processes such as decomposition, nutrient cycling, and maintenance of soil structure. They are especially active in grassland ecosystems such as the tallgrass prairie, where much of the net primary productivity is allocated belowground and ultimately processed by heterotrophic soil organisms.

Soil organic matter of Iberian open woodland rangelands as influenced by vegetation cover and land management

Journal Articles & Books
Diciembre, 2013

Spanish rangelands occupy more than 90,000km² of land grazed by millions of domestic and wild animals. Organic matter content of soil is an essential component for fertility and productivity in both, natural and human-induced ecosystems. Despite its importance to soil quality, soil organic carbon has been little studied in these rangelands. The main goal of this study is to assess the amounts and characteristics of soil organic matter in grazed open woodlands of SW Iberia as influenced by vegetation cover and land management.

Effect of land management and soil texture on seasonal variations in soil microbial biomass in dry tropical agroecosystems in Tanzania

Tanzania

Soil microbes are an essential component of most terrestrial ecosystems; as decomposers they are responsible for regulating nutrient dynamics, and they also serve as a highly labile nutrient pool. Here, we evaluated seasonal variations in microbial biomass carbon (MBC) and nitrogen (MBN) as well as microbial activity (as qCO₂) for 16 months with respect to several factors relating to soil moisture and nutrients under different land management practices (plant residue application, fertilizer application) in both clayey (38% clay) and sandy (4% clay) croplands in Tanzania.

review of a community-based approach to combating land degradation: dryland salinity management in Australia

Journal Articles & Books
Diciembre, 2008
Australia

Degradation of farmland caused by salinisation is a major environmental issue in Australia. To combat salinisation a community-based approach has been adopted. This paper reviews the nature and effectiveness of this approach, describing its rationale, strengths and weaknesses. The community-based approach is shown to have been highly successful in raising awareness and providing education about the problem of dryland salinity in Australia, and has encouraged group participation in managing the problem.

Seagrass rehabilitation off metropolitan Adelaide: a case study of loss, action, failure and success

Journal Articles & Books
Diciembre, 2014

Heavy losses of 6200 ha of seagrass off the Adelaide metropolitan coast since 1949 have had substantial implications for beach management, fisheries and biodiversity. Here, we describe for managers some promising initial trials to develop a cost‐effective method to rehabilitate some of these lost seagrasses.

Exploring the links between local management and conservation applying the ecosystem services concept: conservation and tourism service in Camargue, France

Journal Articles & Books
Diciembre, 2013
Francia

This article aims at testing whether the ecosystem services framework helps in understanding the link between local management and biodiversity conservation. Tourism was analysed in Camargue (France), a wetland area of high biodiversity value, via semi-structured interviews with local stakeholders. Three types of stakeholders were interviewed: protected area managers, livestock farmers and public institutions. This was done to examine whether they manage the land to enable tourism and/or maintain or restore the ecological state of ecosystems.

From the office to the field: Areas of tension and consensus in the implementation of the National Environmental Policy Act within the US Forest Service

Journal Articles & Books
Diciembre, 2010

We conducted an online survey (n = 3321) followed by five focus groups with Forest Service employees involved in compliance with the National Environmental Policy Act (NEPA) to explore agency views of how NEPA should be implemented within the agency. We filter these perceptions through the lenses of different functional groups within the agency, each with its own role in agency compliance with NEPA and its own suite of perceived accountabilities.

Effects of landscape protection on farm management and farmers' income in Norway

Journal Articles & Books

Noruega

Protected Landscapes (PLs) are increasingly used in Norway to conserve cultural (human modified) landscapes. In many cases the maintenance of agricultural activities in PLs is required to preserve landscape character. Whilst research exists on land conservation policies in general, the particular effects of PL on management and adjustment of the farms involved have not received attention in the literature. We present results from a questionnaire sent to owners of agricultural land within PLs in Norway.

Home Range and Site Fidelity of Imperiled Ornate Box Turtles (Terrapene ornata) in Northwestern Illinois

Journal Articles & Books
Diciembre, 2012

The destruction of prairies has led to the decline of the ornate box turtle (Terrapene ornate) across much of its range. Land management agencies are considering translocation programs to restore populations to areas from which they have been extirpated. For these conservation efforts to be successful, long-term posttranslocation monitoring is necessary to ensure that translocated individuals behave and use habitat similarly to unmanipulated individuals.
