Diversity of the riparian vegetation of high Andean wetlands of the Junín region, Peru
The diversity of the riparian vegetation of five high Andean lagoons of the Junin region was evaluated between March and December of 2017. The sampling of the riparian vegetation was carried out by means of the transect method. The unidentified species were collected for later identification in the herbarium. The diversity was determined by floristic composition, abundance and frequency, and by species richness indices of Simpson and Shannon-Wiener. In the Pomacocha Lagoon, the floristic composition was represented by 43 species, distributed in 15 families, with the most abundant species being Aciachne pulvinata, Azorella crenata and Geranium sessiliflorum and the most frequent Aciachne pulvinata. In the Laguna Tragadero, the floristic composition was represented by 17 species, distributed in 10 families, with the most abundant species being Pennisetum clandestinum and Eleocharis sp and the most frequent Polypogon interruptus. In the Cucancocha Lagoon, the floristic composition was represented by 19 species, distributed in 7 families, with the most abundant species being Calamagrostis sp and Wernberia humbellata and the one of most frequent Carex ecuadorica. In the Incacocha Lagoon, the floristic composition was represented by 22 species, distributed in 11 families, with the most abundant and frequent species being Alchemilla pinnata. In the Ñahuinpuquio Lagoon, the floristic composition was represented by 20 species, distributed in 9 families, with the most abundant species being Pennisetum clandestinum and the most frequent species Pennisetum clandestinum, Juncus arcticus and Muhlenbergia andina. The results obtained contribute data on the diversity of riparian vegetation of high Andean wetlands in the Junin region, Peru.
