Acacia (especially Acacia drepanolobium)

Acacia drepanolobium, commonly known as whistling thorn or umbrella thorn, is a thorny shrub or small tree native to East Africa. It forms distinctive umbrella-shaped canopies that provide shade and habitat. This acacia has a mutualistic relationship with ants that nest in its swollen thorns; the ants defend the tree from herbivores and competitors. The tree also produces bright yellow flowers that attract pollinators. Its adaptations help it survive in dry, nutrient-poor soils, making it a vital part of its ecosystem by supporting various wildlife and maintaining ecological balance.
