Dehesas, highly species-diverse Mediterranean open woodlands, are seriously affected by this decline, because of a generalized regeneration failure of oak, which compromise their long-term stability. Traditionally, dehesas were the wintering areas for transhumant herds, but transhumance is disappearing in the Mediterranean, due to multiple causes. Reductions in grazing intensity or grazing abandonment have been proposed to improve oak regeneration in dehesas, but the effect of the recovery of non-continuous grazing practices such as transhumance has not been tested to date. We measured different indicators of holm oak regeneration and condition in dehesas under transhumant grazing and in dehesas under permanent grazing in southern Spain. Oak juveniles were remarkably less browsed and their canopies covered a much higher area in transhumant estates. As a consequence, the median density of saplings was more than four times higher in transhumant than in permanently-grazed estates. Although transhumant grazing is necessarily associated with a reduction in the stocking rate across the year, the timing of grazing was always included as a predictor in the best models to explain the condition and density of holm oak. Our results suggest that the lack of oak regeneration in dehesas can be caused not only by the increases in stocking rates, but also by the recent abandonment of traditional grazing practices like transhumance. We propose the recovery of seasonal grazing regimes based on transhumant pastoralism as a measure to improve the conservation status of dehesas.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bergmeier, Erwin</style></author><author><style face="normal" font="default" size="100%">Petermann, Jörg</style></author><author><style face="normal" font="default" size="100%">Schröder, Eckhard</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Geobotanical survey of wood-pasture habitats in Europe: diversity, threats and conservation</style></title><secondary-title><style face="normal" font="default" size="100%">Biodiversity and Conservation</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Agroforestry</style></keyword><keyword><style  face="normal" font="default" size="100%">Dehesa</style></keyword><keyword><style  face="normal" font="default" size="100%">Habitats directive</style></keyword><keyword><style  face="normal" font="default" size="100%">Hudewald</style></keyword><keyword><style  face="normal" font="default" size="100%">Pasture-woodland</style></keyword><keyword><style  face="normal" font="default" size="100%">Silvopastoralism</style></keyword><keyword><style  face="normal" font="default" size="100%">Traditional land-use</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://link.springer.com/10.1007/s10531-010-9872-3http://www.springerlink.com/index/10.1007/s10531-010-9872-3</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">2995 - 3014</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Agro-silvopastoral land-use has a long tradition throughout Europe. Depending on the region, wood-pasture occurs as vanishing relic of historical land-use, or still more or less widespread as multiple-use rangeland. A new development is that former intensively managed land is being left to evolve towards wood-pasture as an economically and ecologically favourable alternative. In a review of European wood-pasture habitats we distinguish 24 types based on the geobotanical criteria of region, structure, land-use and tree species composition. The European wood-pasture types may be classiﬁed as hemiboreal and boreal (4 types), nemoral old-growth (7), nemoral scrub and coppice (5), meridional old-growth (2), meridional scrub and coppice (4), and grazed orchards (2). Wood-pasture forms part of the cultural heritage of Europe, and may add signiﬁcantly to the preservation of regional biodiversity. The role of wood-pasture in ecological restoration planning and the possibilities of maintaining or enhancing features of wood-pasture deserve more recognition. Many wood-pastures suffer from regeneration failure and are over-mature. Other threats to wood-pasture include abandonment, intensiﬁcation, oak disease, overgrazing and clearance. In the European Union Habitats Directive, woodpasture habitats are represented but rather inconsistently. We suggest neglected woodpasture habitat types to be considered for inclusion. Wood-pasture may form an important element for the economic integrity of rural areas aiming to improve ecological quality‚ provided they are managed sustainably</style></abstract><issue><style face="normal" font="default" size="100%">11</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">a.

Hence, from 2001 to 2005, the Silvoarable Agroforestry for Europe project developed a systematic process to evaluate the biophysical and economic performance of arable, forestry, and silvoarable systems in Spain, France, and The Netherlands. A biophysical model called “Yield-SAFE” was developed to predict long-term yields for the different systems and local statistics and expert opinion were used to derive their revenue, costs, and pre- and post-2005 grant regimes. These data were then used in an economic model called “Farm-SAFE” to predict plot- and farm-scale proﬁtability. Land equivalent ratios were greater than one, showing Yield-SAFE predicted that growing trees and crops in silvoarable systems was more productive than growing them separately. Pre-2005 grants in Spain and The Netherlands penalised silvoarable systems, but post-2005 grants were more equitable. In France, walnut and poplar silvoarable systems were consistently the most proﬁtable system under both grant regimes. In Spain, holm oak and stone pine silvoarable systems were the least proﬁtable system under pre-2005 grants, but only marginally less proﬁtable than arable systems under post-2005 grants. In The Netherlands, low timber values and the opportunity cost of losing arable land for slurry manure application made silvoarable and forestry systems uncompetitive with arable systems under both grant regimes.</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ferreira, D.

DYNAMICS AND ENVIRONMENTAL CONSEQUENCES – This paper presents the general context within which the montado landscape changed in the inner Alentejo during the 20th century as well as some of the environmental consequences, such as soil degradation and modification of the local climate. In large areas nowadays abandoned, the landscape dynamics depends more on environmental limitations created by soil degradation that on purely socio-economical factors.</style></abstract></record></records></xml>
