Executive Summary: This project includes an introductory documentary program addressed to the public to show the oak forests in Mexico and their relevance in the country and globally. It is composed of two parts, one is devoted to highlighting the main features of oaks and their habitats, and the second is focused on the oak diversity that exists in one of the best cloud forests in México located in Hidalgo and Puebla states. In this area more than 40 oak species have been reported (Ortiz & Villaseñor 2017Valencia-A, S., et al. 2017), of which 3 are threatened and several are Data Deficient (Carrero, C. et al. 2020). It aims to raise awareness among the population of the importance they have in maintaining the ecological balance of the areas where they are located. The cloud forest represents one of the most oak-biodiverse forests in Mexico, and one of the most susceptible to disappear because of climate change and anthropic activities (González-Espinosa et al. 2011). 

Target Species:
Quercus rubramenta (VU)
Quercus hirtifolia (EN)
Quercus delgadoana (EN)
Quercus acherdophylla (DD)
