Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2013
Date Assessed: 2011-04-06
Assessor(s): Garbajal, R., Gómez Valverde, M.A., Navarro, L., Rodríguez-Oubiña, J. & Serrano Pérez, M.
Reviewer(s): Ortiz, O., Peraza Zurita, M.D. & Bilz, M.
Contributor(s): Peraza Zurita, M.D.
Justification:
Petrocoptis grandiflora is listed as Vulnerable due to its restricted distribution, with presence confirmed in only five locations. Habitat availability and human alteration are the main factors limiting its expansion.

Geographic Range [top]

Range Description: Petrocoptis grandiflora is endemic to the provinces of Ourense and León, Spain (Dirección General de Medio Natural y Política Forestal del MARM 2007). It can be found in five locations, with an area of occupancy of 26 km² (Carbajal et al. 2011).

Population [top]

Population: Total population size has been estimated in 48,740 individuals (Carbajal et al. 2011). The number of specimens in each subpopulation ranges from 407 to 21,680 depending on habitat availability. The population is in general stable and it seems that recruitment is appropriate (Commission of the European Communities 2009).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This pioneer hermaphrodite herb grows on cracks and ledges of calcareous-dolomitic walls (Carbajal et al. 2011). Frequent accompanying species are Leontodon farinosus, Saxifraga trifurcata, Campanula adsurgens, Erinus alpinus and Rhamnus pumila ssp. legionensis, among others.
Systems: Terrestrial

Threats [top]

Major Threat(s): Open cast mining, mountaineering and rock climbing have been described as threats to this species (Commission of the European Communities 2009).

Conservation Actions [top]

Conservation Actions: This species is listed on Annex II of the Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). The taxon is included in the regional catalogues of protected species of Galicia and Castilla y León. It is listed as VU D2 in the Spanish Red Databook 2010 (Carbajal et al. 2011).

The majority of subpopulations occur in the protected area Parque Natural Serra da Enciña da Lastra, Ourense. In León, the species occurs within the SCI Montes Aquilianos-Sierra del Teleno.

Climbing activities should be forbidden on walls where the species is present and quarrying has to be controlled. The location Sobrado, in León, should be object of strict protection (micro-reserve). Plant material should be collected and monitoring and research about variability should be developed.
