Abstract

The bryophytes form a conspicuous group of the planet’s flora, their ecological contribution in terms of species richness and coverage in many habitats is essential for the balance of ecosystem. In Colombia there is an approximate record of 715 species of Marchantiophyta (liverworts), which present their greatest richness in the Andean region. The study was carried out in the Chingaza National Natural Park - Suasie sector given its ecological and water importance for the surrounding municipalities. The main objective of this study was to determine the diversity of the liverwort community in the Suasie sector of the Chingaza NNP. For this, three surveys were made in transects of 2x50 m in an altitude gradient, in each transect the liverworts present from four phorophytes (trees and shrubs), chosen at random were sampled. The collected samples were identified for analysis of composition and diversity of the community. As a result, it was possible to demonstrate the variation in the composition and abundance of liverworts along the gradient, based not only on the estimated indices, but also on the association with the vegetation cover of each sampling site. With a total of 47 registered species, the high diversity of the sector under study is supported. In this way, the richness found in this gradient contributes to current and future conservation strategies for the park.
