Notes: This is a singular point in the Portuguese orography and a case study (ied) in what concerns lichens. In fact, it is only a small hill of dolomite origin that is incrusted in the west of Portugal with a (not so high) elevation, about 150m. But this together with the influence of the ocean nearby gives a special habitat to this place. The surroundings, a landscape of dune forested with pines trees, including the biggest consolidated dune of Europe, are poor in lichen diversity. The vegetation of the hill in contrast with the neighborhood has an astonishing diversity, the most important phorophytes being Quercus coccifera, Arbutus unedo and Erica arborea, and some Macaronesian type vegetation. The floral interest of the hill granted it the statute of “classified area”.
The place was visit in the past by several lichenologists and one of them, P. P. G. van der Boom, pubblished a paper about 7 years ago reporting 22 new species for Portugal of a total of 228 recorded during his visits to the place, including species observed by others, which constitute the first attempt to give a survey for that site. For instance, one can find there some uncommom species, like three of the genus Roccela, others only observed at higher elevations in Portugal, like Lasallia pustulata, among several others.
