 <![endif]-->  O Nordeste brasileiro tem a maior parte de seu território ocupado por uma vegetação adaptada às condições de aridez (xerófila), de fisionomia variada, denominada “Caatinga”. Este ecossistema é extremamente importante do ponto de vista biológico, pois é um dos poucos que tem sua distribuição totalmente restrita ao Brasil.   De modo geral, a Caatinga tem sido descrita na literatura como pobre e de pouca importância biológica. Porém, levantamentos recentes mostram que este ecossistema possui um considerável número de espécies endêmicas, e que devem ser consideradas como um patrimônio biológico de valor incalculável.   Quanto à flora, foram registradas até o momento cerca de 1000 espécies, estimando-se que haja um total de 2000 a 3000 plantas. Com relação à fauna, esta é depauperada, com baixas densidades de indivíduos e poucas espécies endêmicas. Descrições de novas espécies vêm sendo registradas, indicando um conhecimento botânico e zoológico bastante precário deste ecossistema, que segundo os pesquisadores é considerado o menos conhecido e estudado dos ecossistemas brasileiros.   Além da importância biológica, a Caatinga apresenta um potencial econômico ainda pouco valorizado.
