État de la populationExpert
A study of Quercus hintonii's population in 2000 used survey data and information on land use to map Q. hintonii's distribution and found it covered an area of 18,633 ha (186.33 km2) (Rodríguez and Coombes 2000), although there was no study into the density of Q. hintonii in that area. Having been previously found in Michoacán, it can be assumed that the population size, as well as the extent of occurrence and area of occupancy, have declined as it is now only found in Mexico state. However it is possible that the original occurrences in Michoacán were misidentified.

Description complète des menacesExpert
Disturbance of Quercus hintonii forest disturbance found a very strong relationship between developing human population size and the amount of disturbance (Rodríguez and Coombes 2000). Much of the area is in the process of conversion into avocado plantations and human settlements. There has also been a huge reduction in forest area due to agricultural expansion and logging (A. Coombes pers. comm. 2017). There is clearing of oak forest, to open areas for cattle use (grassland), agricultural (maize), creation of roads and for human settlements. Currently, wood is being extracted from these forests, commercially baking bread and cooking. The forest and soil have been damaged a lot because they perform cultural practices such as that known as the "tumba, rosa y quema", which refers to the demolition of trees and the action of removing the weeds, using machete and finally burning the organic remains, this action sometimes causes fires, which cannot always be controlled, thus increasing the deterioration of the forest (Reyes Jaramillo 2006).

Mesures de conservation recommandéesExpert
Quercus hintonii is grown in three botanic gardens in Mexico as well in overseas collections. Although this species shows a good germination rate, its adaptation to cultivated conditions has been of limited success so more work on cultivation conditions is being done at the Botanic Garden in the University of Puebla (Oldfield and Eastwood 2007).
