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)[

The ovoid-truncate seed cones can range from 15 - 27cm long and 10 - 15cm wide. The green cones can reach weights of 1.5 - 2 kilos. They can take 2 - 3 growing seasons to mature, usually remaining more or less closed on the tree until broken open by animals, particularly squirrels and birds. It is not known if fire stimulates the cones to open[
