The Osa Peninsula
There is no greater ecological paradise in Costa Rica than the Osa Peninsula, home of the world’s largest pacific coast lowland rainforest. The “Osa” is home to more than 50% of the 500,000 animal and plant species that live in Costa Rica, but covers only three percent of the country’s total area. To better understand that statistic, think of it this way, the Osa Penninsula has more plant and animal species than does the United States, but is only .0002% its size! The Osa is the home of the largest population of Scarlet Macaws north of the equator, as well as all four species of monkeys found in Costa Rica. It is also home to the elusive Jaguar, Puma, Ocelot, Tapir, Sloth, and three of the world’s critically endangered sea turtles; the Leatherback, Hawksbill, and Green Sea Turtles.
The flora of the Osa is just as impressive as its fauna in that it not only has the tallest trees in Central America, but it also has the most species of plants and trees than any forest north of Panama. Add in the fact that many endemic animal and plant species call only this area home, coupled with the fact that completely new species of plants and animals are still waiting to be discovered and you will soon understand why so many nature lovers and biologists respect the Osa as natures last true wonderland.
