Serious About the Sierras…………………………….. The Mediterranean Biosphere is one of those special places where, quite literally, different worlds collide to create a unique and diverse landscape of global ecological and cultural importance. The Biosphere’s unique patchwork of habitats is not only a product of Africa’s inexorable geological movement north into Eurasia, but also of the areas geographical location and climatic diversity – a place where Mediterranean and Atlantic weather systems equally fight for primacy.

The Mediterranean Basin is a Global Biodiversity hotspot as identified by Conservation International and the Biosphere has an exceptionally high concentration of protected spaces – most notably Los Alcornocales, Grazalema, Sierra de las Nieves, Sierra Cristallina and Los Reales on the Spanish side and Talassemtane, Al Hoceima and Bouhachem in the Moroccan Rif . On the Spanish side, these wilderness areas hold some of Europe’s highest biodiversity indicators and are also a bottle neck to Western Europe’s most significant bird and whale migrations around the Straits of Gibraltar.

The reasons for the Biosphere’s unique biological diversity have also given rise to a unique and diverse cultural history and within its protected spaces are fascinating archeological reminders of this varied past, stretching over all  human history – from caves inhabited by Neanderthal Man to Roman Castles, Moorish Palaces and Andalucian white washed pueblos, perched improbably on densely forested slopes . For the archeologist and historian, just as for the geologist, botanist or ornithologist – there is something very unique and special about this region
