Grasslands and Shrublands of the Mediterranean Region

Abstract The Mediterranean Region extends to the 1.6% of the world's land surface and more than the half of the Mediterranean-type ecosystems of the world. The remarkable species richness in the Mediterranean Region mainly originates from an exceptional habitat diversity and the presence of several natural barriers facilitating the segregation and differentiation of local taxa and biocoenoses. In this article, we deal with the habitats characterized by grasslands and shrublands that clearly show the adaptations to what could be called “the Mediterranean syndrome”, i.e., the intrazonal Mediterranean grasslands and shrublands (MGS they support communities of insects with major roles in the ecosystem services of control and pollination; they sustain apiculture, and contribute to the prevention of erosion processes and maintenance of the water cycle; they buffer the negative impacts from fertilizers and pesticides and display highly significant aesthetic and recreational values. However, major threats to the provision of ecosystem services mostly originate from climate change, and recent land use changes (such as: “coastalization,” unbalanced grazing activities and abandonment of traditional practices). To mitigate the adverse effects of land use changes, the management of MGS (a) ecosystem sustainability, (b) natural regeneration, (c) multifunctionality, and (d) protection.
