Abstract

GARCIA-MARTINEZ, M.A.  and  RODRIGUEZ, A.. Vegetation and phanerogamic flora of Piedras Bola protected area in Jalisco, Mexico. Polibotánica [online]. 2018, n.46, pp.71-90. ISSN 1405-2768.  https://doi.org/10.18387/polibotanica.46.4.

The Piedras Bola Natural Protected Area (ANPPB) was named and decreed due to the presence of stone spheres in the area which can reach up 1.5 m in diameter. These stones have a volcanic origin and their formation represents an uncommon phenomenon. The area is located in the state of Jalisco, in the western portion of the Transmexican Volcanic Belt. The dominant vegetation type is the oak forest and oak-pine forest. The aim of the present work was to make an inventory of the phanerogamic flora of the area. We carried out 24 explorations between 2011 and 2016 and we enlist 54 families, 170 genera and 262 species. The most representative families were Asteraceae (47 spp.), Fabaceae (40 spp.), Poaceae (28 spp.) and Solanaceae (15 spp.). The results were compared with previous work in the Piedras Bola area and with floristic studies carried out in nearby areas with similar ecological conditions.

Keywords : Ahualulco de Mercado; Sierra del Águila; Sierra de Ameca; stone spheres; Transmexican Volcanic Belt.
