Neltuma alba

Species of tree

Neltuma alba, commonly known as the white mesquite, is a species of flowering tree in the Fabaceae family. It is native to the subtropical regions of South America, particularly in countries such as Argentina, Bolivia, and Paraguay. This tree is valued for its hardiness and ability to thrive in arid environments.

Description

Neltuma alba leaves and pods

Neltuma alba is a medium-sized tree that can grow up to 15 meters in height. It has a broad, spreading canopy and a trunk that can reach up to 1 meter in diameter. The bark is rough and grayish-brown, often with deep fissures. The leaves are bipinnate, with small, oblong leaflets that are bright green in color.

The tree produces small, fragrant flowers that are yellow to cream in color, arranged in dense, cylindrical spikes. These flowers are followed by the development of long, slender pods that contain several seeds. The pods are initially green but turn brown as they mature.

Habitat and Distribution

Neltuma alba is well adapted to dry, arid environments and is commonly found in the Gran Chaco region, which spans parts of Argentina, Bolivia, and Paraguay. It thrives in sandy and well-drained soils and is often found in open woodlands and savannas.

Ecological Importance

The tree plays a significant role in its native ecosystem. It provides habitat and food for various wildlife species, including birds and insects. The seeds are consumed by animals, which aid in the dispersal of the tree.

Uses

Neltuma alba is valued for its durable wood, which is used in construction, furniture making, and as firewood. The tree is also used in agroforestry systems to improve soil fertility and provide shade for crops and livestock.

Conservation

While Neltuma alba is not currently considered endangered, its habitat is threatened by deforestation and land conversion for agriculture. Conservation efforts focus on sustainable management and protection of its natural habitats.
