Convolvulus fernandesii is a vulnerable plant species endemic to Portugal. It forms clusters in limestone cliff crevices and unstable substrates along the coast between Sesimbra and Cabo Espichel, where it has an area of occupancy less than 10 km2. The main threats are potential habitat loss due to urban expansion and grazing. It is legally protected and recommended that its habitat be protected from loss and the impacts of grazing be studied.

Description category description Latin name: Convolvulus fernandesii Common Name: Corriola do Espichel (PT) Photo: Red List Category & Criteria: Vulnerable CITES status: NO This plant is ecologically very specialized. It forms clusters in crevices of limestone outcrops and unstable substrates along the dolomitic limestone cliffs formed in the Jurassic. It prefers a south and east exposure, and is even found in abrupt overhanging cliffs, but it also requires shelter. It sometimes occurs in vegetation thickets and acts as a climber. This plant grows in the following Habitats Directive Short species description: listed habitats (Commission of the European Communities 2009): 5320 Arborescent matorral with Laurus nobilis 8210 Calcareous rocky slopes with chasmophytic vegetation. Convolvulus fernandesii is endemic to Portugal where it is restricted to the coast between Sesimbra and Cabo Espichel. Geographic Range: It has an area of occupancy of less than 10 km族 and an extent of occurrence of 52 km族. Range Map: http://mapservices.iucnredlist.org/IUCN/mapper/index.html? ID_NO=162138
The main threat is the potential expansion of the urbanised areas in Serra da Az坦ia, Aldeia Nova, Pinheirinhos and Pedreira do Cavalo which could lead to further habitat loss along the coast. It is possible that significant reductions in Major Threat(s): the past were caused by grazing goats and fires but there is no actual data to confirm this hypothesis. Trampling could pose a problem but most of the populations are now in areas inaccessible to humans. Convolvulus fernandesii is listed as priority species on Annex II of the Habitats Directive and legally protected in Portugal. It is recommended to protect the species from Conservation Actions: habitat loss due to urbanisation, to study the impacts of grazing, and to carry out species recovery measures. Ex situ conservation of the seeds should be put in place.
