The piedmont dryforest of northwestern Argentina has been under intensive and unplanned forestlogging focused on 12 tree species, without any attempts having been made toensure their regeneration or long-term conservation. In this study, we assessedthe conservation status of these timber species in the piedmont dry forest of northwesternArgentina and compared our results with the IUCN assessment. We considered aninadequate conservation status if the species: (1) occurred in less than 50% ofthe sampled plots, (2) had a density of large trees (more than 40 cm DBH) lowerthan one individual per hectare, and (3) had a density of saplings (more than30 cm in height and less than 9.9 cm in DBH) lower than 30 individuals perhectare. Our results showed an inadequate conservation status for eight of the12 studied timber tree species. Additionally, only seven species werepreviously assessed and categorized on the IUCN Red List, with ourcategorization agreeing with only four of them. The data provided in this workcan serve as a baseline to monitor the population trends of these species;information can also help to prioritize conservation efforts, which isessential considering the high number of tree species that have potentialextinction risk in the short-term.
