Parque Nacional Yaxhá-Nakum-Naranjo. 02/02/06; Petén; 37,160 ha; 17°09'N 089°25'W. National Park, UNESCO Biosphere Reserve. Located within the Reserva de la Biósfera Maya, 97% of the wetland is covered by forested lands, either high or seasonally flooded. It also contains various rivers, lagoons and pools such as the Yaxhá, Sacnab, Juleque, Lancajá and Champoxté. Among the species present are the Morelet's crocodile (Crocodylus moreletti), the white fish (Petenia splendida), the Central American river turtle (Dermatemys mawi), spider monkey (Ateles geoffroyi) and the collared peccary (Tayassu tajacu). It has been estimated that over 90% of the flora in the site has not been studied botanically nor chemically. There exist certain pressures on the site due to illegal extraction of natural resources, and a progressive deterioration in the quality of the water bodies has also been noted. Ramsar site No. 1599.
