In lowland regions on both the Pacific and Atlantic coasts where rainfall levels are not high enough to support rainforest, deciduous tropical forests were once common but are now rarely found. Acacia and copa trees are common, often mixed in with tree cacti, agaves, and a variety of drought-resistant shrubs. A superb example of a deciduous tropical forest can be seen in Sierra de la Botija, in the area around San Marcos de Colón and El Corpus, near Choluteca; other patches are found along the valleys of the Ríos Ulúa, Humaya, Otoro, Choluteca, and Goascorán, around Olanchito in the Río Aguán Valley, and in a few places on the Bay Islands. The forest of El Boquerón in Olancho, with its gliricidia, ceiba, walnut, and fig trees, is a subtropical dry forest.
