|Scientific Name:||Abies hickelii|
|Species Authority:||Flous & Gaussen|
|Infra-specific Taxa Assessed:|
Abies religiosa (Kunth) Schltdl. & Cham. subspecies hickelii (Flous & Gaussen) Strandby, K.I.Chr. & M.Sørensen
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Taxonomic Notes:||A recent morphological evaluation concluded that A. hickelii could be considered a subspecies of A. religiosa (Strandby et al. 2009). This taxonomy has not yet been adopted for the IUCN Red List. Following Farjon (2010) two varieties are recognized for Abies hickelii: the typical variety and var. oaxacana (Martínez) Farjon & Silba.|
|Red List Category & Criteria:||Endangered B2ab(ii,iii,v) ver 3.1|
|Reviewer(s):||Thomas, P., Perez de la Rosa, J. & Rushforth, K.|
The assessment of the species as a whole follows that of the two varieties: while the extent of occurrence increases with all mapped locations included, the estimated area of occupancy is still well under 500 km², the population is severely fragmented and there is likely to be continuous decline, especially in quality of habitat and number of mature individuals.
|Previously published Red List assessments:||
|Range Description:||Endemic to Mexico: Chiapas, Guerrero, Oaxaca, Puebla, and Veracruz.|
Native:Mexico (Chiapas, Guerrero, Oaxaca, Puebla, Veracruz)
|Estimated area of occupancy (AOO) - km2:||208|
|Continuing decline in area of occupancy (AOO):||Yes|
|Estimated extent of occurrence (EOO) - km2:||87651|
|Number of Locations:||4-5|
|Lower elevation limit (metres):||2500|
|Upper elevation limit (metres):||3000|

|Population:||Populations are decreasing and subpopulations are severely fragmented.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Both varieties of this species occur in high mountains of sub-tropical southern Mexico, at elevations between 2,500 m and 3,000 m a.s.l. The soils are of volcanic origin. The climate is cool, moist oceanic, with rain mostly in the winter. There are some pure stands at the highest elevations, but this species is usually mixed with highland pines, e.g. Pinus montezumae, P. pseudostrobus, and P. ayacahuite, and also with Cupressus lusitanica and Quercus spp. Shrubs are e.g. Vaccinium spp., Andromeda spp., Ribes spp. and Fuchsia spp.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||40|
|Use and Trade:||Hickel's Fir is a rare species and its two varieties occur in more or less disjunct, limited stands. Exploitation for timber is minor and its use is local, mainly worked in sawmills for domestic purposes. In cultivation it is extremely rare and limited to some dendrological collections in countries with mild climate, e.g. southern France.|
|Major Threat(s):||Logging may have some impact on this species, but data to evaluate this quantitatively are lacking. For the 1998 Conifer Specialist Group assessment it was assumed that a 20% decline had occurred over the duration of three generations (about a century). Deforestation in the region is an ongoing process, which affects Abies as a late successional tree more than e.g. Pinus, so it is considered that the decline is continuing.|
|Conservation Actions:||More forest reserves with effective management and policing would be required to protect this species from decline.|
