Botanical Description

Pinus nelsonii is an evergreen tree with a rounded, dense crown of upcurved branches; it usually grows up to 6 - 7 metres tall, but can occasionally reach 10 metres. The bole can be around 20 - 30cm 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 plant is harvested from the wild for local use as a food. Pinus nelsonii is by all accounts a rare pine with a scattered occurrence largely limited to limestone outcrops. Its total population almost certainly numbers fewer than 10,000 mature trees, mostly in (sub)populations of a few hundred individuals. It is thought to be in decline due to habitat disturbance and loss associated with increased cattle ranging and incidence of destructive fires associated with this type of land use. 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. ].
