Scientific Name: Abies hidalgensis
Species Authority: Debreczy, Rácz & Guízar
Taxonomic Source(s): Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.
Taxonomic Notes: The type collection, Debreczy et al. DAPC 40323 (holotype BP, isotypes A, E, K, MEXU) was gathered 4.5 km N of the village of Metepec. The number of resin ducts in the leaves, given as 5-7 in the protologue, is highly unusual in the genus, but A. hickelii has 4-12. Abies hidalgensis may only be a variety of A. hickelii with included bracts in the seed cones. It is only known from the type locality.

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2013
Date Assessed: 2011-05-06
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P. & Perez de la Rosa, J.

More research is needed to establish beyond doubt the taxonomic distinctiveness, the approximate size of the population, and the extent of occurrence and area of occupancy. On the basis of what is known, 15+ years after its discovery, an assessment of Vulnerable under D2 reflects the fact that it is only known from a single locality with a small population that could be vulnerable to stochastic events.

Previously published Red List assessments:
2007 Data Deficient (DD)
1998 Rare (R)

Habitat and Ecology [top]

Habitat and Ecology: Grows in cloud forest with Alnus firmifolia, Buddleia cordata, Cupressus lusitanica, Pinus patula, P. teocote, Sambucus mexicana, etc.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 40

Use and Trade [top]

Use and Trade: No uses have been recorded for this species. It has not been taken into cultivation.

Threats [top]

Major Threat(s): No current threats have been identified but if this taxon does stand up to taxonomic scrutiny and if it remains only known from one location, as at present, stochastic events such as a major fire could put the species at extreme risk.

Conservation Actions [top]

Conservation Actions: No conservation actions are known to have taken place.
