underscores the significance of further floristic investigations in Bahia’s Semi-arid region for enhancing our understanding of native species. Disseminating this finding to local communities and guiding effective conservation policies is paramount, given the historical suppression of native vegetation, predominantly due to pastures and agricultural land conversion. These regions show the potential to harbour a rich flora, including rare, endemic and threatened species. Additionally, several native species in these regions are beneficial for human purposes and warrant heightened attention from a conservation standpoint.
