Naranjo / Terminalia amazonia
Distribution & Tree
Nargusta is prevalent across the mainland Neotropics as well as parts of the Caribbean with multiple local names. It’s among Izabal’s most common tropical hardwoods with observed concentrations up to 10 to 12 trees per hectare. Trees can grow up to 50 meters in height with trunks often exceeding one meter. Trucks are highly cylindrical often free of branches up to 20 meters. Naranjo loses its leaves briefly during the dry season. It often develops large buttresses, especially when growing in swampy areas. It grows in a wide variety of soil types, including red lateritic soil derived from volcanic material, but achieves the tallest height in clayey soil.
Due to its fast growth and straight bole, it’s been used on a small scale as a commercial plantation timber in Costa Rica and Panama. Researchers associated with the Smithsonian Tropical Research Institute, Yale University and Universidad Nacional de Costa Rica found that Terminalia amazonia was among the fastest growers among 10 species studied.
