Barra has a tropical forest. Rainforests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 2,000 mm (about 78 inches or 2 meters) and 1700 mm (about 67 inches). The soil can be poor because high rainfall tends to leach out soluble nutrients. There are several common characteristics of tropical rainforest trees. Tropical rainforest species frequently possess one or more attributes not commonly seen in trees of higher latitudes or trees in drier conditions on the same latitude.
