This resource gathers the results of the research work carried out in the paramo complexes "Sonsón" and "Urrao" during March-August 2014. The moorlands sampled in the Sonsón complex were: La Vieja, Las Palomas, Chaverras, Norí and Valle Alto (Salamina). The transects in Urrao were established in the moors Pená and La Horqueta (municipality of Abriaquí), El Junco (municipality of Caicedo), El Sol (municipality of Urrao) and Cerro Plateado (municipality of Salgar). The main objective was to determine the floristic, ornithological, edaphofauna and herpetological composition in each moorland complex and to determine their similarity in different altitudinal ranges covering high Andean forest, shrubland and grassland or moorland ecosystems.
