Methods to improve the recruitment of holm-oak seedlings in grazed Mediterranean savanna-like ecosystems (dehesas)

摘要: Context “Dehesas” are savanna-like ecosystems of human origin that extend broadly in the Mediterranean area Iberian Peninsula. They consist scattered oaks (mainly Quercus ilex subsp. ballota L. holm-oak), an annual grassland layer and interspersed shrubs. These ecosystems, used for grazing wild game, support high plant animal biodiversity provide important environmental services. At present, “dehesas” endangered by lack oak regeneration.
