Probably the most extensive type of forest in the country is the pine forest of the central highlands, technically known as a subtropical moist forest. The most common of the several pine species is the ocote (Pinus montezumae), but the Caribbean pine (Pinus caribaea) is common also. Ocotes generally occur between 600 and 1,400 meters, depending on the region. In wetter areas, they grow in dense forests laced with epiphytes. In drier areas, the ocotes are more widely spaced, often sharing the forest with encino or roble oak trees, particularly around water sources, and frequently with many broadleaf shrubs underneath.
