Diversity of Dos Brazos

With the diversity of habitat, on and surrounding our sanctuary,

our guests have an incredible opportunity to fully comprehend the fascinating natural history of the Peninsula de Osa.

Photo by Jeff ZuhlkeThe area of Dos Brazos de Rio Tigre,  hosts a rare combination of  habitats in a rather small area, creating many different types of “edge” habitats known for supporting a greater variety of species than any single habitat would.

There are very small farms dotted throughout the area, many with “resting “The road is good for birding in Dos Brazos, Osa Peninsula, Puerto Jimenez, Costa Rica Photo by Jeff Zuhlke pastures, scrub and early secondary growth. In the village, there are gardens with flowers, fruit and empty lots overgrown with vegetation rich in forage for smaller species.  Bordering the village and river valleys, sometimes just meters away or within a binocular view, there is old growth and secondary forest ranging from 80 meters to 450 meters elevation.  Mechanical goldmining in the ’70’s and ’80’s produced many lagoons and swamps adding to the diversity of amphibians and species dependent on still aquatic systems. And all around are riparian (river) ecosystems; along small streams, waterfalls and major rivers.  Our branch of the Rio Tigre is changing its temperament close to the lodge, from a fast moving mountain stream to a slower moving, wider river, creating very dynamic and fascinating changes year to year.
