From a historical point of view, various agroforestry systems existed in Europe, of which the wood pastures (Neolithicum), the Dehesas in Spain (*4,500 years old) and the Hauberg of the Siegerland (established in the Middle Age) are the most prominent. Other widespread systems in Europe were hedgerows, windbreaks and Streuobst (orchard intercropping). Due to mechanisation and intensiﬁcation of agriculture, trees have been progressively removed from agricultural ﬁelds and traditional agroforestry systems slowly disappeared. Today, agroforestry systems are again increasing in interest as they offer the potential to solve important ecological and, especially, biodiversity problems, while at the same time enabling the production of food, wood products and fodder for cattle. Although agroforestry systems offer many advantages, many farmers are sceptical of these systems and are critical and risk-averse with regard to adopting new practices. However, in comparison to traditional systems, modern agroforestry systems can be adapted to current farming practices. By selecting suitable trees and appropriate tree management, highquality timber can be produced without inﬂuencing agricultural crops excessively. In future, agroforestry systems will become increasingly important as they offer the prospect of producing woody perennials for bioenergy on the same land area as food and/or fodder plants, while enhancing overall biodiversity.</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%">Pinho, P</style></author><author><style face="normal" font="default" size="100%">Bergamini, A</style></author><author><style face="normal" font="default" size="100%">Carvalho, P</style></author><author><style face="normal" font="default" size="100%">Branquinho, C</style></author><author><style face="normal" font="default" size="100%">Stofer, S</style></author><author><style face="normal" font="default" size="100%">Scheidegger, C</style></author><author><style face="normal" font="default" size="100%">Máguas, C</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Lichen functional groups as ecological indicators of the effects of land-use in Mediterranean ecosystems</style></title><secondary-title><style face="normal" font="default" size="100%">Ecological Indicators</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Ecological indicators</style></keyword><keyword><style  face="normal" font="default" size="100%">epiphytic lichens</style></keyword><keyword><style  face="normal" font="default" size="100%">livestock</style></keyword><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">Nitrophytic</style></keyword><keyword><style  face="normal" font="default" size="100%">Oligotrophic</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus suber</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Ltd</style></publisher><volume><style face="normal" font="default" size="100%">15</style></volume><pages><style face="normal" font="default" size="100%">36-42</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The effects of land-use on species and communities are usually studied by considering high-intensity land-use gradients. However, in many Mediterranean Europe areas, the traditional land-use regime is of low-intensity, including low-impactforestry practices and extensive livestock pasture. This low-intensity land-use is associated with ‘High Nature Value Farmlands’, which occupymore than 50% oftotal farmland area in Mediterranean areas. The objective of this work was to determine the effect of traditional lowintensity land-use on epiphytic lichen communities in Mediterranean cork-oak woodlands. We intend to investigate the value of lichen communities as early indicators of the effects of land-use changes. For that, lichens were sampled along a gradient of low-intensity land-use that included forestry and pasture activities. As lichen diversity variables we considered: (i) total species richness, (ii) total species frequency (LDV), and (iii) richness and frequency of functional groups dividing species according to their eutrophication-tolerance. We found an increase of total species richness with an increase of land-use intensity which is opposite to expectations and which was shown for ﬁrst time in lichens. The increase in total species richness was due to an increase of the number of eutrophication tolerant species accompanied by the maintenance of the sensitive one when we analyzed the lichen-data at the functional response group level. These results ﬁt with the intermediate disturbance hypothesis that predicts higher diversity under an intermediate disturbance due to the coexistence of species with contrasting ecological requirements. Traditionally managed cork-oak woodlands with low-intensity land-use can thus support a high diversity of lichen species. An important outcome was that we conﬁrmed the importance of using ecological indicators based on functional-groups for monitoring changes in ecosystems and, since lichens responded to low levels of land-use intensity, we have also shown the possibility of using lichens as early indicators of the impacts of low intensity land-use.</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%">Andivia, Enrique</style></author><author><style face="normal" font="default" size="100%">VÁZQUEZ-PIQUÉ, JAVIER</style></author><author><style face="normal" font="default" size="100%">FERNÁNDEZ, MANUEL</style></author><author><style face="normal" font="default" size="100%">Alejano, Reyes</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Litter production in Holm oak trees subjected to different pruning intensities in Mediterranean dehesas</style></title><secondary-title><style face="normal" font="default" size="100%">Agroforestry systems</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">á agroforestry systems</style></keyword><keyword><style  face="normal" font="default" size="100%">á litterfall á</style></keyword><keyword><style  face="normal" font="default" size="100%">agroforestry systems</style></keyword><keyword><style  face="normal" font="default" size="100%">climate change</style></keyword><keyword><style  face="normal" font="default" size="100%">climate change á management</style></keyword><keyword><style  face="normal" font="default" size="100%">litterfall</style></keyword><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">pruning</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">quercus ilex á pruning</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://link.springer.com/10.1007/s10457-012-9586-5</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">87</style></volume><pages><style face="normal" font="default" size="100%">657 - 666</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Litterfall is a key process in forests which is sensitive to climatic conditions like precipitation and temperature, and management practices. Therefore, knowledge about litterfall patterns and its associated variables is important for the conservation of Mediterranean ecosystems under conditions of climate change. We aimed to quantify the temporal pattern of litterfall and to investigate the inﬂuence of abiotic variables and pruning on litter production. Litterfall was collected at monthly intervals for 2 years in trees subjected to different pruning intensities in two locations. The effect of pruning, abiotic variables and tree size on litter production was analyzed using a mathematical model. Leaf fall was strongly seasonal with a peak occurring in the wettest month of the year in this area. The variability in leaf fall was mainly related to rainfall and soil water in 2 years and locations. Pruning reduced the amount of litter production during the ﬁrst year following this practice, and might have negative effect on soil fertility and crop productivity in dehesas ecosystems.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>5</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Catry, Filipe X.</style></author><author><style face="normal" font="default" size="100%">Moreira, Francisco</style></author><author><style face="normal" font="default" size="100%">Cardillo, Enrique</style></author><author><style face="normal" font="default" size="100%">Pausas, Juli G.</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Moreira, Francisco</style></author><author><style face="normal" font="default" size="100%">Arianoutsou, Margarita</style></author><author><style face="normal" font="default" size="100%">Corona, Piermaria</style></author><author><style face="normal" font="default" size="100%">De las Heras, Jorge</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Post-Fire Management of Cork Oak Forests</style></title><secondary-title><style face="normal" font="default" size="100%">Post-Fire Management and Restoration of Southern European Forests</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">cork harvesting</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak forests</style></keyword><keyword><style  face="normal" font="default" size="100%">crown regeneration</style></keyword><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">natural regeneration</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2012</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2012///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://link.springer.com/book/10.1007/978-94-007-2208-8/page/1http://www.springerlink.com/index/T14G11G6K89M6643.pdf</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Springer Netherlands</style></publisher><isbn><style face="normal" font="default" size="100%">978-94-007-2207-1</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This chapter concerns the ecology and post-fire management of cork oak forests.

We collected variables associated with vegetation features, bird community and chewing defoliators. &amp; Results The two systems differed significantly in oak trunk diameter, oak and shrub cover, tree and shrub diversity. Ground bird densities were higher in SM with fragmented shrub cover. In DM, higher woody vegetation cover and diversity can promote shrub birds and leaf warblers. Oak defoliation was mainly attributed to the sawfly Periclista andrei. Sawfly defoliation was significantly higher in SM and negatively correlated with shrub cover. &amp; Conclusions Our results highlight (1) the relevance of management activities conducted at the shrubby layer, (2) the need of an increase in tree diversity and density and (3) the maintenance of a mosaic landscape in order to improve the bird community richness and reduce the defoliation impact in montado system.</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%">Tárrega, Reyes</style></author><author><style face="normal" font="default" size="100%">Calvo, Leonor</style></author><author><style face="normal" font="default" size="100%">Taboada, Ángela</style></author><author><style face="normal" font="default" size="100%">García-Tejero, Sergio</style></author><author><style face="normal" font="default" size="100%">Marcos, Elena</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Abandonment and management in Spanish dehesa systems: Effects on soil features and plant species richness and composition</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Ecology and Management</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Land use change</style></keyword><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">Oak dehesa</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus pyrenaica</style></keyword><keyword><style  face="normal" font="default" size="100%">Species richness</style></keyword><keyword><style  face="normal" font="default" size="100%">Topsoil</style></keyword><keyword><style  face="normal" font="default" size="100%">Understory composition</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year></dates><volume><style face="normal" font="default" size="100%">257</style></volume><pages><style face="normal" font="default" size="100%">731-738</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Quercus pyrenaica dehesas have been traditionally used as communal extensive grazing systems in the Leo´n province (NW Spain). In this region, recent abandonment of rural areas and the subsequent gradual decrease in livestock load have led to the invasion of shrubs in the understory, increasing the risk of fires. Indeed, even if there is no need of creating new pasturelands for livestock breeding, the remaining landowners keep on burning to clear these montane patches. Alternatively, the regional administration encourages shrub cutting as a better way of managing these areas and preserving the pasturelands. Our aim was to determine the effects of the dehesa abandonment and shrub cutting on plant species richness (annual herbs, perennial herbs and woody plants) and species composition, as well as on topsoil properties. For that, we compared three types of dehesas with differentmanagement regimes: (1) grazed dehesas (used at the present), (2) abandoned dehesas (more than 20 years without grazing) and (3) dehesas where shrub cutting was applied after abandonment (i.e. cleared dehesas). We selected three replicates or stands per dehesa type. The highest organic matter content (O.M.), total nitrogen (N) and available phosphorus (P) were found in cleared dehesas, while the lowest values corresponded to the grazed ones. Abandoned dehesas were characterized by the highest values for available calcium (Ca2+). No significant differences were detected regarding the vegetation richness values (S alpha, gamma or beta), although higher mean values of S alpha and gamma were found in grazed dehesas, and lower values in the cleared ones. Concerning the vegetation life forms, grazed dehesas held significantly greater species richness and cover of annual herbs, while abandoned dehesas had significantly higher woody species cover. Both grazed and abandoned dehesas harboured plant species (38 and 13 species, respectively),which were exclusively found in one dehesa type. Contrary to that, cleared dehesas scarcely had ‘‘exclusive’’ species. To conclude, our results indicated that shrub cutting alone (not followed by livestock grazing) may cause loss of plant species richness, suggesting that it is not the most appropriate management method to restore vegetation, except for reducing the risk of fire.</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%">Verdú, J.

These semi-arid mountain stands, where thuriferous juniper trees grow in low-density open woodland, are seriously endangered: (i) In the Atlas mountains, the thuriferous juniper stands are heavily degraded as a result of the intensive wood removal and livestock activity in these densely populated areas. This situation, which will soon become irreversible unless remedial measures are urgently taken, has produced impoverished soils and hillside instability while contributing to desertiﬁcation. (ii) In Spain, although livestock activity and cultivation have strongly reduced areas occupied by Juniperus thurifera, stands are still numerous and, in some regions, show a good regeneration due to conservation measures. (iii) In France, the decline in human and livestock activities over recent decades has led to a recolonization of some of the Juniper stands by pines or oak.

These semi-arid mountain stands, where thuriferous juniper trees grow in low-density open woodland, are seriously endangered: (i) In the Atlas mountains, the thuriferous juniper stands are heavily degraded as a result of the intensive wood removal and livestock activity in these densely populated areas. This situation, which will soon become irreversible unless remedial measures are urgently taken, has produced impoverished soils and hillside instability while contributing to desertiﬁcation. (ii) In Spain, although livestock activity and cultivation have strongly reduced areas occupied by Juniperus thurifera, stands are still numerous and, in some regions, show a good regeneration due to conservation measures. (iii) In France, the decline in human and livestock activities over recent decades has led to a recolonization of some of the Juniper stands by pines or oak. A forest management system that enables these original stands to survive and regenerate must be undertaken without delay. The dynamics of evolution of these stands is quite different north and south of the Mediterranean. In both cases, conservation measures are urgently required to protect or rehabilitate these original stands with ﬂoristic, ecological and socio-economic interest.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Moreira Huhn, Elizabeth</style></author><author><style face="normal" font="default" size="100%">Euzabeth, Moreira Huhn</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Estructuras y critérios para la ordenación de &quot;montados&quot; de alter do chao (alentejo)</style></title><secondary-title><style face="normal" font="default" size="100%">II Congreso Forestal Español</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">Montado (cork tree forest)</style></keyword><keyword><style  face="normal" font="default" size="100%">sustainnability</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1997</style></year></dates><pub-location><style face="normal" font="default" size="100%">Pamplona</style></pub-location><pages><style face="normal" font="default" size="100%">417-422</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">An inventory of the &quot; montado&quot; (cork tree forests) has been made, making it possible from that point to determine the desirable (padrón de normalidad) and real (mean values) structures. Following, a comparison with the general· structure of the montado of south Portugal has taken place. Also the structure of the cork tree forest under the influence of different utilizations has been studied. Conclusion: The cork tree forest as an ecosystem of multiple uses lacks management, range management in terms of harmonization of the exploitation of cork in combination with different compatible activities like lifestock, game management (hunting) and others.At the end, management standards have been established for the present case, based upon the principIe of montado sustainability.

Two of the questions we sought to answer were (i) in the case where the same disturbance persists, whether these coppice stands reach a state of “equilibrium” based on auto-succession or they continue to change, and (ii) in the case where disturbance stops, whether the present dominant species (Q. ilex or C. sativa) continues to be dominant (high resilience) or an other species (Q. pubescens ?) could replace it. A third case exists, i.e. a change of the “disturbance” in order to obtain a “sustainable” development, but, in that case, biological or socio-economical criteria must be defined. In order to highlight the first stages of these possible changes, germination abilities of these species were studied and compared. For Q. ilex coppice stands, it can be said that there would appear to be a partial allelopathic inhibition of Q. ilex germination, to which Q. pubescens is less sensitive. For C. sativa, this phenomenon was not found. We also briefly discuss the main characteristics of a programme which tests some biological criteria for a sustainable development.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Granda Losada, M</style></author><author><style face="normal" font="default" size="100%">Prieto Macias, P M</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">CONTRIBUCIÓN DE PRATENSES ANUALES EN LA EXPLOTACIÓN DE PASTOS NATURALES DE LA DEHESA EXTREMEÑA</style></title><secondary-title><style face="normal" font="default" size="100%">II Reunión Ibérica de Pastos y Forrajes Badajoz</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">management</style></keyword><keyword><style  face="normal" font="default" size="100%">phosphorus fertilization</style></keyword><keyword><style  face="normal" font="default" size="100%">Stocking rate</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1989</style></year></dates><pages><style face="normal" font="default" size="100%">213-220</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Mediterranean semiarid pastures show a better maintenance capacity due to several management practices (stocking rate, fertilization).
