<br/><br/> <br/><br/>ABSTRACT<br/><br/>Erythrina crista-galli is a native tree from South America with an important role on pharmaceutical<br/>studies. The objective of this study was to model the ancient and current ecological niches distribution<br/>of E. crista-galli in South America, contributing to the discussion about species management and<br/>conservation. A reduction in the potential area of species occurrence was detected by comparing<br/>past and present distribution. Based on the obtained results, it is expected that this species<br/>tends to expand its frontiers if the natural dynamic of the extant populations is guaranteed in<br/>southern South America. Therefore, management and conservation of E. crista‑galli should focus<br/>on allowing the expansion of native forest formations where this species occurs. Additionally,<br/>further studies on the medicinal properties of the species may valorize and promote a higher<br/>interest in rational exploitation and conservation of E. crista-galli in its natural environment.<br/><br/>Keywords: maximum entropy, corticeira-do-banhado, Brazilian Pampa.
