The darker green trees are acajou (mahogany) and the others are cedar.
We have land about 20 minutes north of here and we've planted cedar and mahogany trees. They are coming along nicely and will be worth a fortune in a couple of years. The idea is to show people that a tree farm, if well managed, can be a financial success and a way to prevent deforestation. Potatoes, manioc and some other veggies (that I don't recognize) are planted around the trees and cultivated regularly.
