In order to determine whether microsites are limiting seedling recruitment and regeneration of Espeletica uribei (an endemic frailejon, a valuable species subject to conservation in the Parque Nacional Natural Chingaza) ten biotic and abiotic variables were evaluated from E. uribei seedling microsites as well as from sites without seedlings. The variables associated with seedling establishment were distance from the nearest reproductive adult, the quality of exposure to light, and associated herbaceous structure. Reduced distances from the nearest reproductive adult made it difficult for the seeds to reach distant microsites due to the principle wind dispersal type (anemochory). Open gaps and associated herbaceous structure positively affect the germination capacity and establishment of the species. The results suggest that E. uribei recruitment is limited by the availability of microsites that meet these conditions. These are important factors to consider when planning future projects for the conservation and restoration of this species.
