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 km² and an extent

2. The main threat is the potential expansion of the urbanised
areas in Serra da Azóia, 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.
