CORNEJO-TENORIO, Guadalupe et al. Flora and vegetation of hill El Águila, Michoacán, Mexico. Bot. sci [online]. 2013, vol.91, n.2, pp.155-180. ISSN 2007-4476.

A list of vascular plants of El Águila hill, the higher mountain located in the municipalities of Lagunillas and Morelia, in the Mexican state of Michoacán is given. The field work was carried out from 2007 to 2010. The flora comprises 105 families, 343 genera, 633 species, and 42 infraespecific taxa. The most diverse families were Asteraceae (153 species), Fabaceae (53) and Poaceae (34). Genera with the largest species richness were Salvia (17), Stevia (12) and Verbesina (11). Herbs comprise 72.4% of the whole flora. Based in physiognomic features and species abundance, five vegetation types are described. Pinus-Quercus forest and Quercus forest were the most diverse vegetation types ((286 y 383 species, respectively). According to NOM-059-ECOL-2010 five species are included within risk category Under Special Protection (Cedrela dugesii, Cupressus lusitanica, Dahlia scapigera, Gentiana spathacea, and Laelia speciosa), and one more as Endangered (Tilia americana var. mexicana). Efforts to conserve the vegetation and flora in the study area should be developed taking in account the problems derived for land-use changes.

Keywords : Asteraceae; Morelia; Pinus forest; Quercus forest; subtropical scrub; Salvia; vegetation.
