GUERRERO-HERNANDEZ, Ricardo; GONZALEZ-GALLEGOS, Jesús Guadalupe  e  CASTRO-CASTRO, Arturo. Floristic analysis of Abies forest and adjacent cloud forest in Juanacatlán, Mascota, Jalisco, Mexico. Bot. sci [online]. 2014, vol.92, n.4, pp.541-562. ISSN 2007-4476.

A floristic analysis of a fir forest and the adjacent cloud forest located at western Jalisco was made. We obtained a list of vascular plants consisting of 80 families, 195 genera and 290 species, with a floristic diversity index of 210.33 species/km², which is high when compared to other similar forested areas. The most diverse families in number of species are Asteraceae (46), Fabaceae (22) and Orchidaceae (18). This plant community is very similar to those described for fir forests in Nueva Galicia and the cloud forests from the Transmexican Volcanic Belt. There are five species in some risk category within the Norma Oficial Mexicana NOM-059-SEMARNAT-2010 (Abies flinckii, Comarostaphylis discolor subsp. discolor, Juglans major var. glabrata, Ostrya virginiana y Tilia americana var. mexicana). Patches of Abies flinckii are proposed as a conservation area due to its relictual condition.
