Although ethnobotanical knowledge is considered potentially valuable information for several human disciplines, it is currently declining due to a decrease in the transmission of cultural knowledge and the depletion of natural resources. Consequently, focused efforts are required to compile such information and ultimately facilitate its diffusion. Bogotá D.C. consists of a large territory of rural and urban zones which has become a place of diverse cultural dynamics due to complex processes of historical evolution, making it an important target to conserve ethnobotanical knowledge. Here, we made a thorough compilation of ethnobotanical data for Bogotá focusing on plant common names and developed a freely available online tool (Platform of Plant Common Names of Bogotá) with the aim of preserving and promoting the transmission of biocultural heritage. The compiled dataset consists of over 2,226 combinations between scientific and common names which may be queried using the online tool, leading to specific pages that display several additional features. Since its launch, the online tool has been visited over 6200 times, mainly by Colombian users under the age of 34, which is conveniently in line with our goal of improving the intergenerational transmission of biocultural heritage.
