Barro Colorado Island is famous for being the most intensely studied tropical forest in the world. It is an artificial island of 1,560 hectares that was created during the construction of the Panama Canal. When the Chagres River was dammed to form Gatún Lake, a vast valley was flooded and one of its hills was cut off by water and became Barro Colorado Island. In 1923, at the request of a group of scientists, this island was declared a Biological Reserve, the first Tropical Rainforest Reserve in America, and a research laboratory was installed. In 1946, Barro Colorado was turned over to the Smithsonian Tropical Research Institute, and in 1979, five peninsulas were added on the mainland to declare it a Natural Monument. For more than 100 years, thousands of scientific studies have been carried out in Barro Colorado that have helped us better understand the functioning of the world's tropical ecosystems and the importance of their inhabitants.
