The ground cover in almost all the Paul da Serra, is composed of underbrush, reminiscent of its former use as grazing site, stressing among other the Feiteira (Pteridium aquilinum), Highland bent, (Agrostis castellana), broom (Cytisus scoparius ssp. scoparius, C. striatus and C. multiflorus), the gorse (Ulex europaeus ssp. latebracteatus and U. minor), St. John's wort (Hypericum perforatum) or pelicão (linarifolium Hypericum and H. humifusum) and Thymus micans, an endemic species of Madeira, confined to the central mountain massif.
