Similar to many man-made systems, long-term wooded grasslands conservation depends on sustainable use practices. Regeneration of the tree layer is indispensable to assure wooded grassland maintenance. Several studies in Spanish dehesas and Portuguese montados generated concerns regarding the long-term conservation of these agro-silvo-pastoral systems. In the present study, we tested if tree regeneration issues documented for the Iberian Peninsula also affected wooded grasslands located in another Mediterranean area inside and outside Natura 2000 network. The size structure of Quercus suber L. stands, and the abundance and height of seedlings and saplings were determined at farm and landscape scales, in grazed, grazed and tilled wooded grasslands, and non-grazed woodlands to test the compatibility of management type for tree regeneration. A frequency model of size structure was calculated to estimate the probability of cork oak stand survival in a medium and long term time period. New evidences of a generalised absence of regeneration in grazed wooded grasslands emerged from all the study sites. Some management practices are indicated for the long-term conservation of the habitat.</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%">ARISTA, M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE STRUCTURE AND DYNAMICS OF AN ABIES PINSAPO FOREST IN SOUTHERN SPAIN</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%">ABIES PINSAPO</style></keyword><keyword><style  face="normal" font="default" size="100%">forest dynamics</style></keyword><keyword><style  face="normal" font="default" size="100%">MEDITERRANEAN FIR</style></keyword><keyword><style  face="normal" font="default" size="100%">Regeneration</style></keyword><keyword><style  face="normal" font="default" size="100%">SIZE STRUCTURE</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1995</style></year><pub-dates><date><style  face="normal" font="default" size="100%">1995///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">74</style></volume><pages><style face="normal" font="default" size="100%">81 - 89</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The forest composition and age-diameter relationships of Abies pinsapo were studied in a natural forest in the Nature Reserve of the Sierra de Grazalema (southern Spain).

Abies pinsapo was the dominant species, Quercus rotundifolia and Quercus faginea were the other important overstorey species. The diameter distributions of A. pinsapo were skewed toward the larger size classes, with a large seedling proportion of about 70%. Abies pinsapo establishment rates were higher in the gaps.

Seedlings and saplings with suppressed growth can survive for a mean of 40 years, constituting a pool from which canopy trees may be recruited.
