KENYA SHADE TREE

Opis

Acrocarpus fraxinifolius is native to the tropical regions of Asia. It is a fast-growing, deciduous tree, which annually can grow 1.3-3 m (4.25 – 10 ft), attaining heights of 30-60 m (100–200 ft) and a diameter of over 200 cm. A. fraxinifolius is a pioneer tree, one of the first to regrow in a cleared area. It is very sensitive to frost. Acrocarpus is recommended for erosion control because of its deep root system, up to 4.5 m (15 ft), which holds soil in place on hillsides and along rivers.

Zastosowania

It functions as a shade tree on tea and coffee plantations in countries such as Kenya and Uganda. The wood of Acrocarpus fraxinifolius is hard and strong resembling ash and walnut so that it often substitutes for these two species in construction and fuel needs. It also has potential to be used as a windbreak. The leaves can serve as fodder for animals and the flowers produce nectar and pollen for bees. Although a legume, it apparently does not have nitrogen-fixing nodules. The leaves are suitable for use as mulch.
