What it is

When Gatún Lake flooded with the canal, a hilltop became an island and was set aside as a study station in 1923, now one of the world's most important sites for tropical ecology. Its 50-hectare forest plot started permanent tree censuses.

The reserve was created in 1923 (Canal Zone); Smithsonian administration came in 1946. The date given is the founding of the station.
