Scientific Name: Moehringia fontqueri
Species Authority: Pau

Assessment Information [top]

Red List Category & Criteria: Endangered B1ac(iv)+2ac(iv) ver 3.1
Year Published: 2011
Date Assessed: 2011-03-23
Assessor/s: Peñas, J. & Lorite, J.
Reviewer/s: Blanca, G., Peraza Zurita, M.D. & Bilz, M.
Justification:
Moehringia fontqueri is listed as Endangered because its area of occupancy is very reduced and although the species seems to be not particularly threatened at present, it has a severely fragmented range and could be easily affected by stochastic events. There are extreme fluctuations in the number of mature individuals.
History:
2006 Endangered (IUCN 2006)
2006 Endangered
1997 Rare (Walter and Gillett 1998)

Geographic Range [top]

Range Description: This species is endemic to the Sierra Nevada mountain range in Almeria and is found mainly on the north slopes. It also appears in the ravine of Ohanes on the south slopes (Peñas de Giles and Lorite 2004). Its geographic range is 200 km² (Commission of the European Communities 2009).

Population [top]

Population: It has been considered a single population, although very large and severely fragmented into 71 subpopulations comprising a total of 115,000 individuals. The actual area of occupancy is less than 2.4 km².
Fluctuation was observed in individuals reproductive rate and a high rate of abortion of seeds (40%) is evident, with few seeds apparently viable for flowering.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It grows in steep areas, developing in cracks and crevices of vertical siliceous rocks, usually in favourable microclimate without direct sunlight. It forms part of the phytocenosis of chasmophytes of the alliance Saxifragion nevadensis (Centrantho nevadensis- Sedetum brevifolii and communities of Saxifraga nevadensis and Moehringia fontqueri). Plants living in similar territory are Androsace vandellii, Saxifraga trabutiana, S. nevadensis, Asplenium septentrionale ssp. septentrionale, Centranthus nevadensis and Cystopteris fragilis.

It is a Hemicryptophyte that germinates and sprouts in the middle of May. Flowering begins in early June (in individuals who are at lower altitudes) and continues until early August (for those that live at higher altitudes), with a peak in mid July. In some individuals fructification occurs in July but most do in August, ripening towards the end of this month. The dispersal of seeds occurs immediately after fruition, the capsules adopt a mature pendulous, so that seeds often get very close to the parent plant, often remaining on the same cleft or in the same crevice.
Systems: Terrestrial

Threats [top]

Major Threat(s): There are no direct threats to the species. But the extreme fluctuations of the population, low ecological flexibility and the restricted habitat make the species vulnerable to natural disasters like fires, droughts, diseases etc. Human activities do not threaten the species directly at present, but some subpopulations are potentially threatened by stock-breeders, roads and trails and reforestation activities.

Conservation Actions [top]

Conservation Actions: Moehringia fontqueri is listed on Annex IV of the Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). The distribution area is included in the Biosphere Reserve and National and Natural Park on the Sierra Nevada mountain range (proposed as a SCI). Seeds are stored in seedbanks.
