Management and conservation programs require accessible scientific evidence to effectively plan and achievetheir goals. Facing regional and species-specific threats, Gonopterodendron sarmientoi, an endangered tree nativeto the Gran Chaco region, requires scientific evidence to support management and conservation actions, notablyin forest management and territorial planning. To bridge this crucial gap, we developed indices that integrategenetic, evolutionary, morphological, threat-related, and ethnobotanical data concerning G. sarmientoi at alandscape level. Across twenty-four localities of this species, we have created four distinct indices. The first indexamalgamates data on genetics, functional traits, and paleoclimate information. The second index incorporatesdata on threats stemming from deforestation and climate change scenarios. The third index provides supplementary insights into the species’ utilization by indigenous groups. Finally, the fourth index combines all theaforementioned data to prioritize the most valuable and threatened localities. Through this comprehensiveapproach, we have identified specific in-situ and ex-situ management and conservation actions for G. sarmientoi.This approach considers broader-scale conservation efforts and considers large-scale variations and processes.The indices effectively link scientific data with actionable insights, providing decision-makers involved withG. sarmientoi with concise information that encapsulates the most pertinent aspects of species conservation.
