| description | A study was made of the flora and vegetation of the summit of Cerro Potosí, located in the Southern part of the State of Nuevo León. The principal objective was to anafyze the changes that have occurred in the vegetation after 27 years, using as reference the paper of Beaman & Andresen (1966) on the vegetation and floristics of the area.Sampling by means of transects through four communities: alpine meadow, subalpine meadow, Pinus culminicola scrub and P. hartwegii forest was carried out. Intensive and selective collecting was accomplished above the altitudinal level of 3500 m.The results show that alpine meadow and P. culminicola scrub decreased their areas, and that P. culminicola is not resistant to fire. Some of the dominant elements of subalpine meadow increased their distribution. A vascular flora of 95 species in 77 genera and 36 families is reported. Protection of this fragüe and unique ecosystem is proposed. |

Se realizó un estudio de la flora y vegetación de la cima del Cerro Potosí, al sur del estado de Nuevo León, con el propósito de analizar las modificaciones ocurridas en la vegetación en un período de 27 años, tomando como referencia el trabajo de Beaman y Andresen (1966) sobre la vegetación y florística del área.El muestreo se llevó a cabo mediante transectos que comprendieron cuatro comunidades vegetales: pradera alpina, pradera subalpina, matorral de Pinus culminicola y bosque de P. hartwegii. Se realizaron colectas intensivas y selectivas que incluyeron la zona a partir de la cota altitudinal de 3500 m.Los resultados indican que las áreas ocupadas por la pradera alpina y el matorral de P. culminicola se redujeron considerablemente, encontrándose que P. culminicola no es resistente al fuego. La pradera subalpina incrementó su distribución, comportándose en la cima y en el declive oeste y sur como comunidad disclímax. Se encontraron 95 especies de 77 géneros y 36 familias de plantas vasculares. Se considera urgente el establecimiento de acciones tendientes a proteger lo que persiste de este frágil y único ecosistema.
