Botanical Description

Pinus maximartinezii is an evergreen tree with a broad open crown of irregular branches; it can grow up to 16 metres tall. The short, twisted and contorted bole can be 40 - 50cm in diameter[ 329 Title The Gymnosperm Database Publication Author Website http://www.conifers.org/index.htm Publisher Year 0 ISBN Description A vast amount of information on conifers and families of gymnosperms. , 1212 Title New Trees Publication Author Grimshaw J.; Bayton R.; Wilks H. Publisher Kew Publishing; London Year 2009 ISBN 1842461737 Description Provides comprehensive botanical descriptions and horticultural commentary on over 800 tree species that have been introduced to cultivation in recent decades. ]. The trees are heavily exploited for their large edible seeds, which are consumed locally and also traded in local markets[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ]. Due to its low stature and branching of the trunk, the timber is little used, though it used to be collected for fuel. Young trees retain an attractive blue juvenile foliage for several years and are grown as ornamentals in Mexico[ 329 Title The Gymnosperm Database Publication Author Website http://www.conifers.org/index.htm Publisher Year 0 ISBN Description A vast amount of information on conifers and families of gymnosperms. ]. Pinus maximartinezii has a limited distribution in central Mexico. Its main threats are fire and over grazing and the subsequent erosion which result in few seedlings that succeed in establishing themselves. Intensive harvesting of cones and seeds may also diminish its chances of reproduction. Two disjunct locations are known although it is possible that other subpopulations exist in the intervening areas. A recent decline in at least the quality of habitat has been observed in the main subpopulation in Zacatecas due to grazing and erosion. The plant is classified as 'Endangered' in the IUCN Red List of Threatened Species(2013)[ 338 Title IUCN Red List of Threatened Species Publication Author Website http://www.iucnredlist.org/ Publisher Year 0 ISBN Description A list of plants under threat and facing possible extinction, usually with brief details of the threats and information on habitat. ].
