Trinidad, part of the twin-island country of Trinidad and Tobago, is located just off the coast of Venezuela. Because of its close proximity to continental South America, the biological diversity on the tropical island is quite unique, with coastal, marine, forest, freshwater, savanna, and man-made ecosystems. Trinidad also has a wide biodiversity of plant and animal species, some of which are endemic to the island.
The research station is located on the north bank of Caroni River, a mile north of the Arena Forest Reserve. The land surrounding the research station is comprised of intact forest, former plantations, farmland, rivers, streams, floodplains, and quarried land.
Diverse wildlife inhabit the research area, including anteaters and armadillos, brocket deer, agoutis, boa constrictors, iguanas, and geckos. There is also a wide variety of bird species, including parrots and the iconic Scarlet Ibis that can be found nesting in the taller trees of the Caroni river riparian zone.
