Description
The 2016 Colombia Peace Agreement ushered in a new era for Colombia with the end of the longest-running conflict in the Americas. This period has faced significant challenges leading to further civil unrest in recent years. Caquetá is one of the most unexplored, diverse, and to this day, one of the most violent regions of Colombia and occupies an important geographical position in terms of diversity.  Our research goal is to investigate and conserve orchids and their ecosystems by involving local communities in the creation of in situand ex situ conservation strategies, ultimately offering the communities an alternative mode of subsistence through tourism, cultivation, and legal orchid trade.  During the development of this project, we recorded 96 genera and 414 species of orchids, exceeding a previous inventory by 272 species. The documented species diversity in the region could dramatically increase in the next few years with additional collecting efforts in the eastern slope of the Andes nested in Caquetá. About 9% (414/4600) of all Orchidaceae species recorded in Colombia are reported in this area, showing the important role of the Andean-Amazonian foothills and other ecosystems of this region. We have trained 10 local students and over 100 members of different local communities in vegetative and in-vitro reproduction of orchids. Native orchid nurseries have been built for research, propagation, and plant tourism in three municipalities of Caquetá. This research follows the reproductive aspects of orchids with ornamental value and conservation priorities, including seed germination. Orchids brought to our nurseries in Florencia-Caquetá were monitored weekly during 2021 - 2022. Twenty-four orchid genera were recorded, of which 49 species and 157 individuals have been followed.  Orchids flowered mostly during the dry season (Nov.-Feb.). Twelve lowland growing species were prioritized for in-vitro reproduction. For this species manual auto-pollination was carried out with a success rate of 66.6% in the formation of fruits. The percentage of seed viability was tested with tetrazolium chloride before in vitro culture indicating 65% of the seeds for all tested species were viable. Although the germination and growing success is high, it has been limited to few species to date and is still being customized for our regional lab. We have developed two tourist interpretive trails near Florencia, Caquetá, field guides for hummingbirds and butterflies, for orchid inventories, and other resources. At least four different civil society reserves have adopted our traditional circa situm orchid breeding and conservation strategies. Next, we will work with former FARC combatants in the Departments of Caquetá and Meta implementing this project in the highlands of the eastern Andean Colombia mountain range.
