Whilst dehesa forest sustainability problems associated to exhaustive use of grazing resources have been indirectly approached by European Union authorities, providing support for artiﬁcial plantations over treeless land, no mention is made to natural regeneration techniques. In this sense, the formulated model allows for natural regeneration of already established ageing stands as a complement or even a substitute of actual reforestation practices. The proposed methodology is neither designed to determine optimal rotation of tree species nor optimal decorticating or pruning cycles of cork oaks and holm oaks, respectively. Instead, this information enters the model exogenously through knowledge of region speciﬁc silvicultural cycles for those commercially relevant tree species, and the optimisation program acts as an optimal land use allocator and thus a practical tool for policy analysis purposes. In addition to existing cost beneﬁt analysis applications in dehesa ecosystems, the presented model allows in one side eﬃcient evaluation of long term management dynamics —thus oak woodlands sustainability can be tested for suﬃciently large time horizons—, and in the other, management decisions, instead of being forced through predeﬁned scenarios, correspond to the optimal actions a decision agent would take from the complete set of feasible possibilities given actual land use and tree age distributions.</style></abstract></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.

This paper deals with the effects of grazing pressure in two Holm oak (Quercus ilex) stands in Ogliastra (cen­ tral-eastern Sardinia, Italy), with particular reference to the interactions with the natural regeneration proces­ ses. There is a positive interaction (facilitation) between shrubs and seedlings of tree species, as observed in other similar studies carried out by the same authors in other areas of Sardinia. Rubus ulmifolius proved to be the most efficient shrub for the protection and growth of saplings; the other shrub species play a less marked facilitating role. Although the density of shrubs hosting Holm oak seedlings is fairly high, their age and small size confirm that the current grazing pressure is incompatible with any chance of growth of the sa­ plings and success of the natural regeneration. The conservation of these stands must therefore rely on the rationalisation of human activities through the exploitation of a whole range of resources.</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%">Catry, Filipe Xavier</style></author><author><style face="normal" font="default" size="100%">Rego, Francisco Castro</style></author><author><style face="normal" font="default" size="100%">Bugalho, Miguel Nuno</style></author><author><style face="normal" font="default" size="100%">Lopes, Tito</style></author><author><style face="normal" font="default" size="100%">Silva, Joaquim Sande</style></author><author><style face="normal" font="default" size="100%">Moreira, Francisco</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Effects of fire on tree survival and regeneration in a Mediterranean ecosystem</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%">mortality</style></keyword><keyword><style  face="normal" font="default" size="100%">natural regeneration</style></keyword><keyword><style  face="normal" font="default" size="100%">post-ﬁre recovery</style></keyword><keyword><style  face="normal" font="default" size="100%">Tree species</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2006</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2006///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://linkinghub.elsevier.com/retrieve/pii/S0378112706007614</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">234</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Portugal is the only European Mediterranean country where the annual average burnt area has increased in the last two decades. Although forest ﬁres at national level annually represent very important losses, few studies evaluated the mortality and the capacity of auto-regeneration of the different tree species in burnt areas. After a wildﬁre that occurred in September 2003, we started a research project in a public protected area in central west Portugal. The main goal of this study, still ongoing, is to evaluate the post-ﬁre regeneration capacity of different tree species occurring in the country. We expect to quantify the survival/mortality rates of selected tree species in relation to variables such as ﬁre severity, tree height and diameter, and evaluate species regeneration strategies as well as their growth rates after ﬁre disturbance. In this study 667 trees from 11 species were selected for monitoring, namely: Castanea sativa, Crataegus monogyna, Eucalyptus globulus, Fraxinus angustifolia, Olea europaea var. sylvestris, Pinus pinaster, Pinus pinea, Pistacia lentiscus, Quercus coccifera, Quercus faginea and Quercus suber. Results obtained two springs after ﬁre, show that almost all broadleaved trees (9 species) survived to the ﬁre. Contrarily, the majority of coniferous trees died after the ﬁre. Despite the very low mortality observed in broadleaved trees, most of them did not regenerate from the crown, but only from the base, trunk or roots, which means that the recovering process will be much slower. Exceptions to this were cork oak and eucalyptus. Within native species, Quercus suber is by far the most resilient to ﬁre. For most part of the monitored tree species, which resprouted from the base of the trunk, Eucalyptus globulus was the one that recovered faster, followed by Fraxinus angustifolia and Quercus faginea.</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%">Broncano, Maria José</style></author><author><style face="normal" font="default" size="100%">Retana, Javier</style></author><author><style face="normal" font="default" size="100%">Rodrigo, Anselm</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Predicting the Recovery of Pinus halepensis and Quercus ilex Forests after a Large Wildfire in Northeastern Spain</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Ecology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">burn severity</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest</style></keyword><keyword><style  face="normal" font="default" size="100%">natural regeneration</style></keyword><keyword><style  face="normal" font="default" size="100%">post-fire recovery</style></keyword><keyword><style  face="normal" font="default" size="100%">resilience</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2005</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2005///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.springerlink.com/index/10.1007/s11258-005-0974-z</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">180</style></volume><pages><style face="normal" font="default" size="100%">47 - 56</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Quercus ilex and Pinus halepensis are two of the most common tree species of the western Mediterranean basin. Both species regenerate reliably after ﬁre: P. halepensis colonizes recently disturbed areas by eﬀective seedling recruitment, while Q. ilex resprouts vigorously after disturbances. For this reason, the natural regeneration of these species after ﬁre should ensure the re-establishment of a forest similar to that which existed before the ﬁre. This study analyzes with a simple simulation model whether or not the relative abundance of monospeciﬁc and mixed forests of these species in the landscape is altered by ﬁre. We also analyze the topographic factors and the forest structure before the ﬁre that determine the changes in forest composition after ﬁre. This study has been carried out in a large ﬁre that occurred in NE Spain. Overall, 33% of plots changed to another community type, but this probability of change varied considerably among community types before the ﬁre. Monospeciﬁc forests of P. halepensis or Q. ilex had a high probability of remaining in their original composition after the ﬁre, whereas the resilience of mixed forests of these two species was quite low. Mixed forests changed for the most part to monospeciﬁc P. halepensis or Q. ilex forests. Analysis of several factors determining these changes indicated that only elevation as a signiﬁcant topographical variable. The eﬀect of ﬁre was to increase the altitudinal diﬀerentiation between the two species. P. halepensis forests that changed to mixed or Q. ilex forests were those of highest elevation, while the mixed and Q. ilex plots that changed to P. halepensis forests were those located at the lowest elevations. Concerning structural variables before ﬁre, density of Q. ilex trees before the ﬁre showed a much greater eﬀect than P. halepensis density in determining the post-ﬁre community. Finally, burn severity also inﬂuenced the changes observed. For both P. halepensis and Q. ilex forests, plots that changed to another forest type were mainly those that burned more severely. In the case of mixed forests, even low ﬁre severities involved high probabilities of change to monospeciﬁc forests.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Espelta, J.

The large extension of the burned areas, as well as the fact that non-fire-prone vegetation has been severely affected, lead to ponder over the natural regeneration patterns occurring, and over the best strategies to restore and manage the burned areas. In the present study, we review the land use changes and the natural regeneration patterns observed after the large wildfire that occurred in Bages-Bergueda in 1994. The fire resulted in: (i) the creation of new croplands and pastures in previously forested areas, (ii) the expansion of mixed oak (Quercus ilex and Q. cerrioides) coppices, (iii) the failure of natural regeneration of the dominant tree species (Pinus nigra), leading to the appearance of areas without any tree regeneration. In this context, we discuss the results of different experiments carried out to reforest P nigra stands and to ameliorate the structure of mixed oak coppices.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;periodical: FIRE AND BIOLOGICAL PROCESSES&lt;br/&gt;pub-location: PO BOX 321, 2300 AH LEIDEN, NETHERLANDS</style></notes></record></records></xml>
