Figure 13: These giant leucaenas grown on the coast of the Philippines about 100 miles north of Manila, are just one year old. I spent an hour walking around under them. A year earlier, the site had been barren and festooned by a coarse, weedy, cutting grass called imperata. Now the grass was gone and the soil was black and bedecked by worm castings. Moreover, the original rainforest vegetation was beginning to regenerate in the shade, shelter and moist conditions beneath the canopy of greenery.
