Crofting and bumblebee conservation: The impact of land management practices on bumblebee populations in northwest Scotland

Journal Articles & Books
december, 2010

The northwest of Scotland is a stronghold for two of the UK's rarest bumblebee species, Bombus distinguendus and Bombus muscorum. The predominant form of agricultural land management in this region is crofting, a system specific to Scotland in which small agricultural units (crofts) operate rotational cropping and grazing regimes. Crofting is considered to be beneficial to a wide range of flora and fauna. However, currently there is a lack of quantitative evidence to support this view with regard to bumblebee populations.

Landscape context and plant community composition in grazed agricultural systems of the Northeastern United States

United States of America

Temperate humid grazing lands are an important component of the landscape of the northeastern United States, as well as of the economy of this region. Unlike their European counterparts, little is known about the basic ecology of managed grasslands in this region. During an 8-year survey of 28 farms across the northeastern United States, we sampled the vegetation on 95 grazed plots, identifying 310 plant species, and collected data on topography, climate and soils.

Arbuscular mycorrhizal associations in Boswellia papyrifera (frankincense-tree) dominated dry deciduous woodlands of Northern Ethiopia

Ethiopia

This study assessed the arbuscular mycorrhizal (AM) status of Boswellia papyrifera (frankincense-tree) dominated dry deciduous woodlands in relation to season, management and soil depth in Ethiopia. We studied 43 woody species in 52 plots in three areas. All woody species were colonized by AM fungi, with average root colonization being relatively low (16.6% - ranging from 0% to 95%). Mean spore abundance ranged from 8 to 69 spores 100g⁻¹ of dry soil. Glomus was the dominant genus in all study sites. Season had a strong effect on root colonization and spore abundance.

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

Journal Articles & Books
december, 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.

ZigBee-based wireless sensor network localization for cattle monitoring in grazing fields

Journal Articles & Books
december, 2010

This paper presents the design of a localization scheme in wireless sensor networks (WSN) for cattle monitoring applications in grazing fields. No additional hardware was required for distance estimation since they were performed using the link quality indication (LQI), which is a standard feature of the ZigBee protocol. The ratiometric vector iteration (RVI) algorithm was implemented and modified to work with LQI measurements instead of the usual received signal strength indication (RSSI).

Impacts of management and enclosure age on recovery of the herbaceous rangeland vegetation in semi-arid Kenya

Kenya

Establishment of seasonal grazing enclosures has become an important rangeland rehabilitation strategy in semi-arid regions. This study assessed the impact of enclosure age and enclosure management on the vegetation composition in the Njemps Flats range unit, Lake Baringo Basin (Kenya). Six communal enclosures (13-23 years since establishment) and six private enclosures (3-17 years since establishment) were selected.

Physical properties of dystrophic Red Latosol (Oxisol) under different agricultural uses

Journal Articles & Books
december, 2010

Obtaining information about soil properties under different agricultural uses to plan soil management is very important with a view to sustainability in the different agricultural systems. The aim of this study was to evaluate changes in certain indicators of the physical quality of a dystrophic Red Latosol (Oxisol) under different agricultural uses. The study was conducted in an agricultural area located in northern Paraná State.

A model to accompany the combined management of livestock farming systems and woodlands on the Causse du Larzac (Aveyron, France)

France

Once the conditions that led to the creation of the Société Civile des Terres du Larzac (SCTL) have been introduced, the companion modelling approach used with this group of farmers is presented. The agent-based model co-constructed with a group of researchers and technicians is then described, as well as the way it was used to confront scenarios developed by the SCTL to envision management options of the forest massif, with scenarios developed by the farmers to improve the current functioning of their farms

Participatory Land Use Planning as a Tool for Community Empowerment in Northern Tanzania

Peer-reviewed publication
november, 2010
Tanzania

This paper presents several case studies to show how the Ujamaa Community Resource Team (UCRT) has been working within Tanzania’s legal and policy framework to support a diverse range of pastoralists, agro-pastoralists and hunter-gatherers, all of whom face fundamental threats from external appropriation of, or encroachment on, lands and natural resources. The work also responds to local needs to rationalise resource use rights amongst competing local groups, such as farmers and livestock keepers.
