Habitat and Ecology [top]

Habitat and Ecology:

Abies vejarii var. vejarii is a high mountain fir, occurring between (1,900-)2,800 m and 3,300 m a.s.l. on steep mountain slopes near the summits or in cool ravines. The soils are usually poor in humus content, but moist; the climate is cool, with relatively dry summers and wet winters. The species is commonly associated with various species of Pinus and with Pseudotsuga menziesii var. glauca, also with Quercus spp. On the Cerro Potosí it occurs with Pinus hartwegii and P. flexilis var reflexa.

Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species and its infraspecific taxa are relatively rare trees with limited distribution, consequently their importance as timber trees is negligible. The species (including its infraspecific taxa) has been introduced to cultivation in the USA and Europe, but it remains restricted to arboreta and other plant collections despite its attractiveness and suitability especially in regions with warm summers and mild, wet winters. Cultivation from wild origin seed of var. mexicana would under appropriate circumstances contribute to ex situ conservation of this threatened taxon.

Threats [top]

Major Threat(s): The most obvious threat to this taxon is the occurrence of devastating wildfires. It is not a commercial timber tree and logging, if it occurs, is limited.

Conservation Actions [top]

Conservation Actions: Some stands of this taxon occur within protected areas, such as on Cerro Potosí.
