Forests provide important ecosystem services that supply societal needs, such as timber, but this provision is not free of conﬂicts derived from the intensive management of forests. A GIS based approach using data from national forest inventories allows us to identify the provision of timber services and to conduct its valuation. The analysis includes a sample of 37,761 plots for 38 commercial tree species in the Spanish Mediterranean region, where we identify sustainable and nonsustainable forests in terms of harvesting intensities and value both the ﬂow of beneﬁts and their net present value. From the analysis we conclude that non-sustainable forests are providing higher economic returns than sustainable forests for most abundant tree species. However, when analysing long term trends, results show that sustainable forests yield higher economic beneﬁts. This latter perspective is preferred when looking at the value of timber as a provisioning service of forests. According to our results, if we wish to encourage sustainability we need to (a) get lower discount rates adopted for the private sector and (b) ensure longer time horizons.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;publisher: Elsevier B.V.</style></notes></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%">Urbieta, Itziar R</style></author><author><style face="normal" font="default" size="100%">Garcia, Luis V</style></author><author><style face="normal" font="default" size="100%">Zavala, MIGUEL a</style></author><author><style face="normal" font="default" size="100%">Marañón, Teodoro</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Mediterranean pine and oak distribution in southern Spain: Is there a mismatch between regeneration and adult distribution?</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Vegetation Science</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Distribution range</style></keyword><keyword><style  face="normal" font="default" size="100%">Holm oak</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest</style></keyword><keyword><style  face="normal" font="default" size="100%">Niche expansion</style></keyword><keyword><style  face="normal" font="default" size="100%">Pinus spp.</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus spp.</style></keyword><keyword><style  face="normal" font="default" size="100%">regeneration dynamics</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">22</style></volume><pages><style face="normal" font="default" size="100%">18-31</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Questions: What is the current distribution of pine and oak species along environmental gradients in southern Spain? Do pine and oak regeneration niches differ from the environmental niches of adults? Is oak species regeneration favoured under the canopy of pine forests? Location: Forest areas of Andalusia (∼87 600 km2, southern Spain). Methods: We compiled extensive forest inventory data to explore differences in abundance (basal area, m2 ha−1) patterns of adults (dbh &gt;7.4 cm) and regeneration (dbh ≤7.4 cm) of five pine and five oak species. Canonical correspondence analysis (CCA) and generalized linear models were applied to explore species–environment relationships along climatic, edaphic, topographic and fire-frequency gradients. Results: Both pines and oaks segregated along complex environmental gradients, with pines generally dominating in more severe (colder and drier) environments, while oaks dominated in milder, wetter winter areas. In 40-55% of mature pine stands there was a lack of regeneration in the understorey, while in two oak species (Q. suber and Q. canariensis) 70% of stands did not show regeneration. Pine recruits were found at a higher frequency and abundance under the canopy of their congeners, whereas some oaks (Q. ilex) had greater regeneration under mixed pine–oak canopies. Conclusions: Climatic limitations and soil properties partly explained the regional distribution of pines and oaks. We found evidence for an upward shift of Q. ilex recruits towards areas with colder conditions in pine forests, which could be explained by a possible facilitative effect of the pine canopy on seedling establishment.</style></abstract></record></records></xml>
