Lists of trees, where they grow and what they are used for.

In the tropics, uncertain supplies and increasing costs of feed, fertilizer and food coupled with projected population increases are giving the leguminous trees, whose foliage is browsed by animals, a status they have never enjoyed previously.

Trees and shrubs play a dual role in the forage supply, serving both as shade for grass and as forage themselves. In dry tropics, in particular, shrubs and trees are precious for without them stock raising would probably be impossible as pasture grasses die when upper soil layers lose their moisture, but tree roots exploit deep underground moisture and they continue to flourish.
