summary: Montane cloud forests that ensue alongside safe ravines have a fragmented distribution in western Mexico. those forests comprise excessive species richness, and a few endemic species and relict species. We determine montane cloud forests in western Mexico that deserve precedence for conservation and in situ upkeep. We rank the montane cloud forests in keeping with tree species richness, the variety of endemic vascular crops, the variety of species with safeguard prestige, and the presence of relict tree species. We position tree species richness and floristic composition of montane cloud forests from western Mexico in an international context, evaluating them with one hundred ten forests in the course of the global. Then, utilizing Ward's dendrogram, we determine similarities within the floristic composition. additionally, we make certain which species within the montane cloud forests of western Mexico are secure by means of the Mexican Species Act, CITES, or IUCN crimson checklist. Our effects point out that the montane cloud wooded area at Ojo de Agua del Cuervo within the nation of Jalisco is exclusive in that it comprises greater numbers of tree species, endemic vascular crops, and endangered crops than related Asian forests containing historical species. Ojo de Agua del Cuervo is floristically comparable on the frequent point to forests in Asia, in addition to these in Mexico containing Tertiary relict tree species. we suggest a 56,395 ha biosphere reserve that comes with Ojo de Agua del Cuervo and its atmosphere. This proposed reserve may raise the variety of preserved montane cloud forests, that are at present underrepresented between Mexican safe average components
