Yasuni National Park is renowned for its exceptional biodiversity, with over 500 species of birds and over 100 species of mammals, as well as thousands of plant species. The park is home to a wide range of endangered species, including the jaguar, giant otter, harpy eagle, and anaconda. It is also home to several threatened species of primates, such as the howler monkey and capuchin monkey.

In addition to its rich diversity of animal species, Yasuni is also home to a large number of plant species, including many that are unique to the area. The park's forests are home to a range of tree species, including the famous kapok tree, as well as a variety of medicinal plants used by the Waorani people.

The high level of biodiversity in Yasuni is due in large part to the park's location in the heart of the Amazon rainforest, which is considered one of the most biodiverse regions on the planet. The park's diverse ecosystems, including primary and secondary forests, flooded forests, and savannas, provide a range of habitats for different species.

It is important to protect the biodiversity of Yasuni National Park, as the park is home to many endangered species and plays a vital role in the region's ecosystem. The park is also an important source of food, medicine, and cultural practices for the Waorani people, who have lived in the area for thousands of years. Protecting the biodiversity of Yasuni is crucial for the survival of these indigenous communities and for the conservation of the Amazon rainforest as a whole.
