Approximately 10 percent of the area is planted to coffee. Most of the coffee is grown in the shade, but some is grown in the sun. About 7 percent of the area is ungrazed forests. The remainder is used for growing such food crops as plantains, bananas, taniers, yams, and pigeon peas and for orchards and other purposes. Urban expansion is not a significant land use problem.
Forest is the climax vegetation.
Most of the soils are Tropepts and Humults. They are on steep side slopes, mainly in the east-central part of Puerto Rico. The Humatas series, a deep, fine textured Haplohumult has an isohyperthermic temperature regime. The Los Guineos series is an Isothermic Hapludox. They are on steep side slopes in the west-central part of Puerto Rico.
