Land-use changes as major drivers of mountain pine (Pinus uncinata Ram.) expansion in the Pyrenees

Journal Articles & Books
Diciembre, 2010
España

To assess the spatial patterns of forest expansion (encroachment and densification) for mountain pine (Pinus uncinata Ram.) during the last 50 years at a whole mountain range scale by the study of different topographic and socio-economic potential drivers in the current context of global change. The study area includes the whole distributional area of mountain pine in the Catalan Pyrenees (north-east Spain). This represents more than 80 municipalities, covering a total area of 6018 km².

Effects of juniper encroachment on herbage production and biodiversity in a natural grassland: Preliminary results

Journal Articles & Books
Diciembre, 2012
Grecia

The encroachment of woody species in natural grasslands has recently increased, especially in arid and semi-arid environments. In the Mediterranean region, this is mainly attributed to the dramatic decrease of the traditional human activities such as pastoral management and fuelwood collection, which controlled the encroachment of woody species. The purpose of this study was to investigate the effects of Juniperus oxycedrus encroachment on herbage production and floristic diversity in a natural grassland.

Vegetation Response to Piñon and Juniper Tree Shredding

Journal Articles & Books
Diciembre, 2016

Piñon (Pinus spp.) and juniper (Juniperus spp.) expansion and infilling in sagebrush (Artemisia L.) steppe communities can lead to high-severity fire and annual weed dominance. To determine vegetation response to fuel reduction by tree mastication (shredding) or seeding and then shredding, we measured cover for shrub and herbaceous functional groups on shredded and adjacent untreated areas on 44 sites in Utah.

Silvopastoralism in Mediterranean Basin: Extension, practices, products, threats and challenges

Journal Articles & Books
Diciembre, 2012

Ranching generally causes a progressive deforestation. Nevertheless in Mediterranean countries trees are still present in many pastoral systems, here referred to as silvopastoral systems (SPs). Trees provide products as fruits as human food, fruits or leaves as fodder, wood and firewood, environmental services like patches of soil fertility and shelter for animals, and environmental goods such as carbon sequestration, water yield and quality and reinforced biodiversity.

Fire frequency influences composition and structure of the shrub layer in an Australian subcoastal temperate grassy woodland

Journal Articles & Books
Diciembre, 2009
Australia

Little is known about the relationship between fire regimes and plant diversity in Australia's temperate grassy woodlands. The effect of fire frequency on shrubs in grassy woodland remnants across Western Sydney's Cumberland Plain was examined. Shrub species richness and composition were compared in sites that had experienced a high, moderate or low frequency of fire over the previous 20 years. Nine sites were surveyed, three in each fire frequency category; most sites, including all low-fire-frequency sites, had burnt 9-36 months prior to sampling.

Bird foraging height predicts bird species response to woody vegetation change

Journal Articles & Books
Diciembre, 2010

Accurate a priori predictions of the sensitivity of species to vegetation management depend on an understanding of mechanisms underlying species response. To date information on where birds forage in the vegetation strata has been used to predict bird species response to vegetation change caused by livestock grazing. Profiting from this link between vegetation structural diversity and bird diversity, we test whether this variable, bird foraging height, can be used to predict the impact of a different type of habitat alteration; vegetation encroachment.

Reserve labor, unreserved politics: dignified encroachments under India's national rural employment guarantee act

Journal Articles & Books
Diciembre, 2014
India

The rural proletariat constitute a substantial proportion of the global poor. Leading better lives is central to their political practices. In this paper, I aim to elaborate the political practices that attend to these aspirations, interrogations and contests. I examine existing approaches to studying political practices of the rural proletariat. I do this with a focus on India, where the National Rural Employment Guarantee Act (NREGA) is in force since 2005. I locate the program against the backdrop of neoliberal transformations in India.

Participatory planning, management and alternative livelihoods for poor wetland-dependent communities in Kampala, Uganda

Journal Articles & Books
Diciembre, 2009
Uganda

The paper is based on an on-going 3-year study in the wetland communities of Kampala. The study uses participatory methods and aims to contribute to (i) the development of low-income wetland communities, (ii) to prepare these communities to become less dependent on wetlands without receding into poverty, and (iii) the better management of the wetlands. The communities in direct dependence and intimate interaction with Nakivubo wetlands are mainly poor, live and work under hazardous conditions, and their activities pose a threat to the ecological function of the wetlands.

Impact of storm-burning on Melaleuca viridiflora invasion of grasslands and grassy woodlands on Cape York Peninsula, Australia

Journal Articles & Books
Diciembre, 2009
Australia

This paper examines invasion of grasslands on Cape York Peninsula, Australia, by Melaleuca viridiflora and other woody species, and the role of storm-burning (lighting fires after the first wet season rains) in their maintenance. Trends in disturbance features, fuel characteristics, ground layer composition, and woody plants dynamics under combinations of withholding fire and storm-burning over a 3-year period were measured on 19 plots in three landscape settings. Population dynamics of M.

Woody plant encroachment reduces species richness of herb-rich woodlands in southern Australia

Journal Articles & Books
Diciembre, 2008
Australia

Woody plants have been increasing in many woodland and savanna ecosystems owing to land use changes in recent decades. We examined the effects of encroachment by the indigenous shrub Leptospermum scoparium (Myrtaceae) on herb-rich Eucalyptus camaldulensis woodlands in southern Australia. Species richness and compositional patterns were examined under the canopy of L. scoparium and in surrounding open areas to determine the species most susceptible to structural changes. Richness was significantly lower in areas of moderate to high L.

Active land use improves reindeer pastures: evidence from a patch choice experiment

Journal Articles & Books
Diciembre, 2009
Noruega

The industrialization of agriculture in western societies has often led to either intensified use or abandonment of farmland and open pastures, but experimental evidence on how the dynamics of farmed ecosystems affect space use by large herbivores is limited. We experimentally manipulated farmland patches with cutting and (early summer) low- and high-intensity domestic sheep Ovis aries grazing according to traditional use in north Norway.
