El Yunque
El Yunque Natural Rainforest has become one
of the world’s greatest natural wonders due to the
ecological diversity that distinguishes it. Its
captivating beauty has attracted so much attention
that it has even been considered a candidate in
becoming one of the new Seven Natural Wonders of
the World. But how did this forest become the
biological jewel it is today?
•  From the very origins of our civilization, El Yunque has
been of major importance in different aspects.
•  It is believed that the Taíno Indians would worship Yuquiyú,
the god of good, from the peaks of this singular highland.
They called this mountain Yuque, meaning sacred or white
lands, since their peaks were covered with clouds (the
Spanish later mistook the name and called it Yunque).
•  Its unique beauty attracted the Spanish and in 1876 King
Alfonso XII designated 12,000 acres of the Sierra de
Luquillo as a reserve, making El Yunque one of the oldest
reserves in the Western Hemisphere.
•  In 1898, the Spanish-American War Spanish Crown ceded
Puerto Rico to the United States. Five years later, United
States’ President, Theodore Roosevelt, proclaimed the forest
the ‘Luquillo Forest Reserve’.
•  The name was once again changed under the management
of the Forest Service Division of the United States
Department of Agriculture (USDA) to the ‘Caribbean
National Forest/Luquillo Experimental Forest’.
•  In 1976, the United Nations Education Scientific and
Cultural Organization (UNESCO) proclaimed it the first
International Biosphere Reserve in Puerto Rico, under the
program ‘El Hombre y la Biosfera’.
Guanica
With population growth and the need for land,
forests have been threatened worldwide, many of
which have been altered by man. Fortunately
Guánica Dry Forest, classified as a xerophyte
subtropical forest, is one of the best preserved dry
forests in existence.
•  Originally, the forest was a private property in which
farming took place.
•  In 1919 it was established as the ‘Guánica State Forest’.
Because of its importance, it was later designated as a
Forest Reserve in 1985.
•  Due to its complexity of natural and scientific importance,
in 1981, the United Nations Organization (UN), under the
program of the United Nations Educational, Scientific and
Cultural Organization (UNESCO) it was awarded the
distinction of being the second International Biosphere
Reserve in Puerto Rico.
•  This forest has given great importance to scientific research,
vital information to develop a management plan aimed at
forest conservation.
•  Currently, Mr. Miguel Canals of the Department of Natural
and Environmental Resources (DNER), directs the forest
and has participated in many of the scientific research that
has occurred there.
•  A compilation of some of the research done until 1990 was
published in the journal ‘Acta Scientifica’. From 1990
onwards 119 investigations have been conducted in a
variety of fields, such as flora and fauna, archeology,
ecology, and fishery, among others.

El yunque vs. guanica dry forest

  • 1. El Yunque vs. Guanica dry forest Mónica C. del Moral Jaslin Isern Hernán Méndez Fernando Pacheco Danilo Pérez Verónica Torres
  • 2. El Yunque El Yunque Natural Rainforest has become one of the world’s greatest natural wonders due to the ecological diversity that distinguishes it. Its captivating beauty has attracted so much attention that it has even been considered a candidate in becoming one of the new Seven Natural Wonders of the World. But how did this forest become the biological jewel it is today?
  • 3. •  From the very origins of our civilization, El Yunque has been of major importance in different aspects. •  It is believed that the Taíno Indians would worship Yuquiyú, the god of good, from the peaks of this singular highland. They called this mountain Yuque, meaning sacred or white lands, since their peaks were covered with clouds (the Spanish later mistook the name and called it Yunque). •  Its unique beauty attracted the Spanish and in 1876 King Alfonso XII designated 12,000 acres of the Sierra de Luquillo as a reserve, making El Yunque one of the oldest reserves in the Western Hemisphere.
  • 4. •  In 1898, the Spanish-American War Spanish Crown ceded Puerto Rico to the United States. Five years later, United States’ President, Theodore Roosevelt, proclaimed the forest the ‘Luquillo Forest Reserve’. •  The name was once again changed under the management of the Forest Service Division of the United States Department of Agriculture (USDA) to the ‘Caribbean National Forest/Luquillo Experimental Forest’. •  In 1976, the United Nations Education Scientific and Cultural Organization (UNESCO) proclaimed it the first International Biosphere Reserve in Puerto Rico, under the program ‘El Hombre y la Biosfera’.
  • 5. Guanica With population growth and the need for land, forests have been threatened worldwide, many of which have been altered by man. Fortunately Guánica Dry Forest, classified as a xerophyte subtropical forest, is one of the best preserved dry forests in existence.
  • 6. •  Originally, the forest was a private property in which farming took place. •  In 1919 it was established as the ‘Guánica State Forest’. Because of its importance, it was later designated as a Forest Reserve in 1985. •  Due to its complexity of natural and scientific importance, in 1981, the United Nations Organization (UN), under the program of the United Nations Educational, Scientific and Cultural Organization (UNESCO) it was awarded the distinction of being the second International Biosphere Reserve in Puerto Rico.
  • 7. •  This forest has given great importance to scientific research, vital information to develop a management plan aimed at forest conservation. •  Currently, Mr. Miguel Canals of the Department of Natural and Environmental Resources (DNER), directs the forest and has participated in many of the scientific research that has occurred there. •  A compilation of some of the research done until 1990 was published in the journal ‘Acta Scientifica’. From 1990 onwards 119 investigations have been conducted in a variety of fields, such as flora and fauna, archeology, ecology, and fishery, among others.
