• 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
6. History
• In 1876 the Spanish crown declared "Area
Montes" the highest part of the Sierra de
Luquillo.

of the oldest reserves in this hemisphere.
7. History

• In 1976 UNESCO declared the Yunque forest as
a biosphere reserve for the Planet.
8. Unique Characteristics:

• Diversity of ecosystems within the forest
• Home to a wide variety of organisms
*some of them like the Amazona vittata are
endangered*
10. Unique Characteristics:
• The highest peaks of the Sierra de Luquillo

• Life associations
13. Flora
• It has 240 species of trees
• 88 are endemic
• 23 are only found in that forest.
• 150 species of Fern plants
• 50 species of Orchids.
• Divided into subforest depending on vegetation and
organisims:
• Palm forest, full of different palm trees
• Dwarf forest, all the plants and trees are peculiarly small
because of the wind speeds.
• Red tree forest, used for the raising of the puertorican
parrot.
15. Fauna
• 100 species of vertebrates and mammals that are

them are unique to Puerto Rico,
B. Amphibians during the night
• 13 species of the coqui, like the mountain coqui
and the coqui de campo.
20. Data Analysis:
• As we were going deeper, temperatures of the
air, water and ground were degrading.
• The pH ranged approximately 6-7
• Forest humidity variation reflected 0-2
21. Restrictions:
• There are laws that protect El Yunque:
• Forestry Law- Declares forests as a natural resource to
be protected, preserved and expanded. Promotes
passive recreation in forests.
• Law of Conservation of Wildlife- It was created to
