Mediterranean forest ecosystems possess a unique and diverse flora, characterized by a rich understorey dominated by insect pollinated angiosperms, mainly visited by bees gathering nectar and pollen. The present worldwide decline in bee populations raises major concerns, mortality being mostly attributed to agricultural intensification, particularly pesticide use. In this context, since Mediterranean forests are mostly kept free from the application of biocides, these ecosystems can play a major ecological role, by providing habitat and food source for bees. The economic value may result both directly from bee products, such as honey, and indirectly by securing effective pollination to agricultural ecosystems either by human-assisted movement of bee colonies or by bees’ natural range activity. Hence, forests should be further valuated by its pollination ecosystem service. By using a study case we present evidence about the relevance of Mediterranean forest ecosystems as a valuable source of nectar and pollen. We further compare honey types produced over the Mediterranean region, regarding their floral sources. Finally we review different management regimes applicable to Mediterranean forests regarding their relevance for nectar and pollen supply. Results demonstrate the need to implement forest management strategies focused on pollination governance, by promoting habitat conservation for bees in a pesticide free space.
