Geissanthus dentatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Geissanthus dentatus faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Colombian Andes. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce the remaining patches of montane forest where this species occurs. The species' restricted distribution makes it highly vulnerable to localized habitat destruction, with even small-scale clearing activities potentially eliminating entire subpopulations.
Habitat
Geissanthus dentatus is endemic to montane cloud forests and humid premontane forests in the Colombian Andes, typically occurring at elevations between 1,500-2,500 meters. The species inhabits the understory and forest edges of these biodiverse Andean ecosystems, which are characterized by persistent cloud cover and high humidity.
