The National Forest encompasses 28,000 acres and it's characterized by the variation of vegetation, species of coquí, birds and other species.
Purpose of this trip:
• Learn and understand life at El Yunque
• Go beyond theory and lab experience
• Apply knowledge acquired in the lab to evaluate environment.• pH• Temperature• Wind direction• Humidity
• Evaluate and compare results
History
• In 1876 the Spanish crown declared "Area Montes" the highest part of the Sierra de Luquillo.
• At that time it had 12,399 acres of extension.
• For this reason it is understood that the "Yunque forest" should be considered as one of the oldest reserves in this hemisphere.

small because of the wind speeds. • Red tree forest, used for the raising of the puertorican
parrot.
Flora
Fauna• 100 species of vertebrates and mammals

Fauna• The general forest fauna is dominated by
A. reptiles and birds during the day and• find 14 species of lizards including green
