Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Mollusca Gastropoda Stylommatophora Hygromiidae

Scientific Name: Pyrenaearia daanidentata Raven, 1988
Taxonomic Notes: DNA phylogenetic studies show that P. daanidentata is a monophyletic lineage, very closely related to P. cantabrica. Its specific or subspecific status requires further research  (Elejalde et al. 2009).

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2011
Date Assessed: 2010-07-09

This species is endemic to Spain, living only in the western massif of the “Picos de Europa” System in “Peña Santa de Castilla” mountain. It is present only on the south slope of this mountain above 2,000 m. The distribution range of this species is very isolated, living only in one mountain system. Climate change is a potential future threat which might affect this alpine species. It is therefore listed as Vulnerable D2.

Population [top]

Population:This species is very localized and therefore difficult to establish what the population trend is from current data, but it is assumed to be stable.
Current Population Trend:Stable
Additional data:
Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It lives in calcareous rocky slopes with chasmophytic vegetation. Is found above 2,000 m in karst areas, being refugeed under limestone rocks with vegetation in its vicinity. As well as in areas of accumulation of stones. They remain inactive during the dry season showing activity in humid conditions. During the winter months it is protected from freezing by being inactive under seasonal snow.
Continuing decline in area, extent and/or quality of habitat:Unknown

Use and Trade [top]

Use and Trade: This species is not used or traded.

Threats [top]

Major Threat(s): The main threat is determined by a possible global warming, since it is a species of Alpine affinities, living just above 2,000 m. Moreover, its area of occurrence and extent of occurrence are very small, which makes it particularly vulnerable to environmental change. Hybrid forms with Pyrenaearia cantabrica have been identified below 2,000 m, but the extent of the hybridization zone, and the risk of the hybridization process to the survival of the species is unknown.

Conservation Actions [top]

Conservation Actions: The population of the species is found within the National Park Picos de Europa. This ensures the preservation of this natural space. However, the area of occupancy as well as its density and species biology should be studied. The problem of hybridization with P. cantabrica should be quantified. Up to now sampling efforts have been limited to altitudes placed below 2,200 m. It should be tested if the species reaches higher altitudes.
