Gary Hartshorn's enthusiasm was only exceeded by the forest's when he wrote in Costa Rican Natural History that "these forest are by far the most exuberant in Central America. In fact, the Corcovado forests are just as impressive in height as the best forests I have seen in the Amazon basin or the dipterocarp forests of Malaysia and Indonesia." He goes on to note "The Corcovado forests exemplify the popular conception of the tropical rain forest, with a multitude of species, very tall trees, spectacular buttresses, large woody lianas and abundant herbaceous vines. Daniel Janzen, the editor of the same volume speculated that the peninsula contained the complete tropical insect ecosystem from Mexico to Panama.
