Especies de orquídeas (Orchidaceae) en cuatro coberturas vegetales de los predios Cajones y Quimbaya en Filandia, Quindío

This study presents a list of orchids registered in the Cajones and Quimbaya estates in the municipality of Filandia (Quindío, Colombia), categorized as areas of strategic importance for the conservation of water resources, designated under Article 111 of Law 99 of 1993. The work aimed to identify and document the richness of orchids in these estates according to the vegetation cover type. Tours were made over a year to identify species using specialized literature for the Orchidaceae family in the department of Quindío and with the advice of orchid experts. In total, 184 individuals belonging to 36 species were recorded. The results demonstrated that some species had not been previously reported for the municipality of Filandia. Additionally, this study indicates that secondary and riparian forests have a higher richness of orchid species than wooded pastures. This pattern suggests that the structural complexity and microclimatic conditions provided by forests are key determinants for the conservation of these species. Orchids in secondary forests benefit from greater substrate diversity and higher microclimatic stability, while wooded pastures, although less diverse, act as important connecting elements between forest remnants, favoring the dispersal and survival of some species in modified landscapes.
