          Abstract

          This research was carried out in the Ecuadorian Páramo grasslands, between 2900 and 4200 m o.s.l, in Loja, Zamora Chinchipe, Azuay, Cañar, Chimborazo, Bolívar, Tungurahua, Cotopaxi, Pichincha, Imbabura and Carchi provinces. For the identification and taxonomical classification of species there were taken herborized samples and identified by agrostologists. The Hitchcock, Gould, Lombardo and Tovar taxonomic keys were used for the identification. From the grasses family, in the eight study places, 90 species were identified, including 37 genus, being the mains, with higher number of species: Festuca (14), Paspalum (10), Agrostis (7), Calamagrostis (7), Bromus (6), Stipa (5), Poa (5), Agropirum (3), Arrhenatherum (2), Brisa (2) and Andropogon (2).The species that prevailed in the study places were: Agrostis breviculmis, Agrostis exigua, Bromus lanatus, Calamagrostis tarmensis, Festuca humilior, Festuca ortophylla, Festuca weberbaueri and Paspalum bomplandianum. The diversity indexes of the existent meadow species showed values from mean (0.72) to high (0.90), as for their uniformity. This allowed determining that the biodiversity is variable, according to the environmental conditions of the studied Páramo grassland ecosystems. Similar performance was obtained for trees grasses species

          El estudio se realizó en los páramos ecuatorianos, entre los 2900 y 4200 msnm de altitud, en las provincias de Loja, Zamora Chinchipe, Azuay, Cañar, Chimborazo, Bolívar, Tungurahua, Cotopaxi, Pichincha, Imbabura y Carchi. Para la identificación y clasificación taxonómica de especies se tomaron muestras herborizadas e identificadas por agrostólogos. Para la identificación se utilizaron las claves taxonómicas de Hitchcock, Gould, Lombardo y Tovar. De la familia de las gramíneas, en los ocho sitios de estudio, se identificaron 90 especies, comprendidas en 37 géneros, siendo los principales, con mayor número de especies: Festuca (14), Paspalum (10), Agrostis (7), Calamagrostis (7), Bromus (6), Stipa (5), Poa (5), Agropirum (3), Arrhenatherum (2), Brisa (2) y Andropogon (2). Las especies que predominaron en los sitios de estudio fueron: Agrostis breviculmis, Agrostis exigua, Bromus lanatus, Calamagrostis tarmensis, Festuca humilior, Festuca ortophylla, Festuca weberbaueri y Paspalum bomplandianum. Los índices de diversidad de especies pratenses existentes mostraron valores de medios (0.72) a altos (0.90), en cuanto a su uniformidad. Esto permitió determinar que la biodiversidad es variable, según las condiciones ambientales de los ecosistemas de páramo estudiados. Similar comportamiento se obtuvo para especies de gramíneas forrajeras
