The manna ashes are related to wild species of the genus Fraxinus, namely F. ornus (truemanna ash) and F. angustifolia (narrow leaved ash). About two centuries ago, severalvarieties of such species, selected in ancient times, were widely cultivated for extractingthe manna drug. This represented a remarkable economic resource for the region. Mannawas extracted mainly for pharmacological industry, but today it has became a herbalproduct. Irrespective of the processes that reduced this cultivation to the lowest extent, themanna ash landscape is a remarkable peculiarity in the frame of the Mediterranean agrosystems.It is still kept alive as a relict cultivation within a very restricted area on thenorthern slope of the Madonie Mountains, in the countryside of Castelbuono and Pollina,at the eastern border of the Palermo province (Northern Central Sicily) (Raimondo et al.1995). Taking into account that most of the ash crops are presently abandoned or underagricultural replacement, the need of conserving such unique landscape is pointed out here (Raimondo 1980).
