Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA PINOPSIDA PINALES PINACEAE

Scientific Name: Pinus ayacahuite

Infra-specific Taxa Assessed:
Common Name(s):
English Mexican White Pine
Spanish Ocote Gretado, Ayacahuite, Acalote, Pinabete, Pino Gretado

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2011-06-07
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P. & Perez de la Rosa, J.
Justification:

Whilst undoubtedly exploited for its timber, this species is widespread and common in many mountain forests, although becoming rare in the extreme south of its range. Logging has a negative impact in heavily exploited areas where the number of mature trees is declining.

Population [top]

Population: The overall population is decreasing but not to the extent that it falls within any threatened category threshold.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Pinus ayacahuite forms emergent trees in mixed montane conifer forest on mesic sites, or grows in groups or small groves; reaching its greatest extent in Chiapas and W Guatemala. The best stands are on loamy, well drained soils. Its altitudinal range is (1,500-)1,900-3,200(-3,600) m a.s.l. Phenology: the time of pollen dispersal varies with latitude and altitude; in South-Central Mexico it is in May.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: Pinus ayacahuite and its variety P. ayacahuite var. veitchii are both very important and highly sought after timber trees as they are the tallest growing and most regular shaped representatives of the so-called soft pines in Mexico and Mesoamerica. The wood is used for construction, carpentry, furniture and utilities such as containers, pallets and crates as well as wood pulp. This Mexican pine with its large, pendent cones is uncommon in cultivation and restricted to a few arboreta and private parks or gardens with rare trees. Hybrids have been produced by bringing this species together with its close relatives in the subsection Strobi, e.g. P. flexilis, P. monticola, P. strobus and P. wallichiana, the hybrid with the latter is known as P. ×holfordiana A. B. Jacks. and can also be found planted in some tree collections.

Threats [top]

Major Threat(s): Logging, if carried out unsustainably, would be the main threat.

Conservation Actions [top]

Conservation Actions: This widespread variety is present in several protected areas.
