Neltuma juliflora is native to arid and semi-arid regions of the Americas. It thrives in a variety of habitats, including deserts, grasslands, and coastal areas. The species has been introduced to many other regions, including Africa, Asia, and Australia, where it often becomes invasive.

Ecological Impact

The introduction of Neltuma juliflora to non-native regions has led to significant ecological changes. It forms dense thickets that outcompete native vegetation, reducing biodiversity. The tree's deep root system can lower the water table, affecting local water availability.
