Scientific Name: Suboestophora jeresae
Species Authority: Ortiz de Zarate, 1962

Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2011
Date Assessed: 2010-09-08
Assessor(s): Martínez-Ortí, A.
Reviewer(s): Arrébola, J., Gómez Moliner, B.J., Neubert, E., Seddon, M.B., Lutz, M.L. & Nichols, C.
Justification:
This species is endemic to the province of Valencia in Spain. It has an Extent of occurrence of 600 km2, an Area of occupancy of 88 km2 and is restricted to ten locations. Fires are causing a continuing decline in the quality and extent of its habitat therefore it has been assessed as Vulnerable (VU B1ab(iii) + B2ab(iii)).

Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:

This species is found under stones and trunks in wooded areas (pine and evergreen oak forest, Mediterranean shrubs and orange groves), in caves and the surroundings of springs, which provide refuge and dampness. It is found from sea level up to an altitude of 300 m. (Martínez-Ortí and Robles 2003, Martínez-Ortí, 2007).

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: This species is not utilized.

Threats [top]

Major Threat(s): The majority of the populations of this species are in protected areas, nevertheless there are threats that can affect them seriously. The threats include fires, drought, urban expansion, quarrying, road modifications, deterioration of the caves, and specimen collecting. The limited dispersal ability and low population density of this species also make it susceptible to stochastic events.

Conservation Actions [top]

Conservation Actions: The majority of the populations of this species are included in protected areas such as Municipal Natural Place, LIC, Humid Protected Zone or caves (all caves are protected in Valencia). It is recommended that a conservation plan is drawn up for this species and that subpopulations not included in protected areas are also protected.
