Flora Of The Biological And Ecological Interest Site (beis) Of Tichoukt Mountain (middle Atlas, Morocco)

The work deals with floristic diversity and chorology of taxa present in the Biological and Ecological Interest Site (BEIS) of Tichoukt mountain (Middle Atlas, Morocco). Tichoukt mountain is covered by three main kinds of ecosystems : • Forest and matorral ecosystems: dominant species are Quercus rotundifolia (holm oak), Cedrus atlantica (cedar of Atlas), Juniperus phoenicea (red juniper), J. thurifera (thuriferous juniper), J. communis subsp. hemisphaerica (common juniper), Berberis hispanica, Crataegus laciniata. • Spiny xerophytic ecosystem with Cytisus ‎balansae, Bupleurum spinosum, Erinacea anthyllis, ‎Alyssum spinosum... • Rocky (or rupicolous) ecosystem with Ephedra major, Lonicera pyrenaica, Rhamnus atlantica, Globularia liouvillei, Saxifraga longifolia, Aethionema saxatile... The flora is valued at more than 184 species with a remarkable number of rare, threatened and / or endemic species. To give an overview on the flora distribution in the ‎BEIS, localities of species sampled are provided with detailled geographical coordinates ‎for the endemic and/or rare ones.‎
