Organization for Tropical Studies
- Description
- The Organization for
Tropical Studies (OTS) includes about 50 U.S. and Costa
Rican universities and research organizations. A U.S.
non-profit organization, its mission is to provide leadership
in education, research, and wise use of natural resources in
the tropics. Since 1963, about 2000 students from over 30
countries have studied field biology under OTS sponsorship. OTS
owns or has access to several major field stations in Costa
Rica. La Selva Biological Station, the primary OTS facility, is
a rainforest located in the Atlantic lowlands adjacent to the
110,000 acre Braullio Carrillo National Park and was recently
recognized by the National Academy of Sciences as one of the
four premier sites for tropical moist forest research. The Las
Cruces Biological Station includes mid-elevation forest and
botanical gardens near the border of Costa Rica and Panama. The
Palo Verde Station is located within the Palo Verde National
Park in northwestern Costa Rica.
