We examined the impacts of grazing on plant richness and density in the soil seed bank in regard to the different dispersal and life strategy types of the herb layer taxa. Soil seed bank was qualitatively and quantitatively analyzed and contrasting plant guilds were defined according to life strategy type and dispersal mode. Soil seed bank differences between a) the upper and lower soil layers and b) plant functional guild pairs (ruderals vs. non ruderals, including typical forest taxa, and physically-vs. animal-dispersed plants) were statistically tested in overgrazed and sporadically grazed plots. Moreover, correlations in soil seed bank species dominance between overgrazed and sporadically grazed plots were examined by Spearman's Rank correlation. The majority of seeds were found in the upper (0-5 cm) soil layer. Seed density in the deeper (5-10 cm) soil layer was rather poor and did not differ significantly between overgrazed and sporadically grazed plots. In the upper soil layer, both seed density and plant species richness were significantly lower in the overgrazed plots. Overgrazing reduced both species richness and seed density of non-ruderal species in general and typical forest herbs in particular, while it did not affect ruderal species richness and density. Plant species richness and seed density of animal-dispersed taxa were reduced by overgrazing while physically-dispersed species were not affected; it is therefore concluded that large herds of grazers fenced in relatively small areas cannot act as efficient dispersal vectors of the former species. Our findings suggest that, upon cessation of grazing, the soil seed bank is rather inadequate to restore the herb layer of overgrazed forest sites.</style></abstract><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: ADMIN BLDG, 6TH FLOOR, THESSALONIKI, GR-540 06, GREECE&lt;br/&gt;publisher: ARISTOTLE UNIV THESSALONIKI</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%">Bauer, Eva-Maria</style></author><author><style face="normal" font="default" size="100%">Bergmeier, Erwin</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The mountain woodlands of western Crete - plant communities, forest goods, grazing impact and conservation</style></title><secondary-title><style face="normal" font="default" size="100%">Phytocoenologia</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">greece</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean forest</style></keyword><keyword><style  face="normal" font="default" size="100%">quercetea ilicis</style></keyword><keyword><style  face="normal" font="default" size="100%">Silvopastoralism</style></keyword><keyword><style  face="normal" font="default" size="100%">sustainable development</style></keyword><keyword><style  face="normal" font="default" size="100%">wood-pasture</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2011</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2011///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://dx.doi.org/10.1127/0340-269X/2011/0041-0482</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">41</style></volume><pages><style face="normal" font="default" size="100%">73 - 115</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The aim of this study is to classify and describe plant communities of mountain woodlands in the western half of Crete and to relate their species composition to environmental factors with particular reference to grazing. From a total of 232 original phytosociological relevés we classifi ed eight plant communities (plus several subunits). The plant communities were assigned to associations of the class Quercetea ilicis, herein specifi cally to the alliances Erico-Quercion ilicis, Quercion calliprini and Aceri-Cupression sempervirentis. Correspondence analysis revealed a separation of the chiefl y calcifuge Quercus ilex and Q. pubescens associations with more favourable water supply from the woodlands dominated by Q. coccifera, Acer sempervirens, Cupressus sempervirens and Pinus brutia, growing on hard limestone under drier conditions. Species composition in the latter group of woodlands follows an altitudinal gradient, expressing favourable moisture and, on Plattenkalk, nutrient supply at higher elevations. An ecogram was drawn displaying the relative ecological range of each community along moisture and temperature gradients. Silvopastoral impact was different at species response level, and 'tolerators', 'indicators', and 'avoiders' of grazing may be distinguished. Floristic differentiation related to wood-pasture within given associations was not found, indicating high grazing pressure throughout the stands. In most wood-pastures, especially broadleaved (semi-)evergreen, stands are structurally unbalanced, lack tree rejuvenation and require periods of regeneration from browsing. To allow regeneration and monitoring, we advocate sets of sizable exclosures in different areas and elevations, representing all relevant associations.</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><notes><style face="normal" font="default" size="100%">The following values have no corresponding Zotero field:&lt;br/&gt;pub-location: Stuttgart&lt;br/&gt;publisher: Schweizerbart'sche Verlagsbuchhandlung</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%">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></contributors><titles><title><style face="normal" font="default" size="100%">Seed bank composition and above-ground vegetation in response to grazing in sub-Mediterranean oak forests (NW Greece)</style></title><secondary-title><style face="normal" font="default" size="100%">Plant Ecology</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2008</style></year></dates><volume><style face="normal" font="default" size="100%">201</style></volume><pages><style face="normal" font="default" size="100%">255-265</style></pages><isbn><style face="normal" font="default" size="100%">1125800895</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We investigate the persistent soil seed bank composition and its relation to the above-ground ﬂora of grazed and non-grazed sub-Mediterranean deciduous oak forests of NW Greece.
