Maraca - “Ilha de Maraca”, the giant riverine island in the heart of the Urariquera is one of the richest natural biospheres remaining in the world today.  Few tropical ecosystems have been protected as carefully as this critically important reservoir for species preservation and biodiversity.  A remarkable ecological reserve, Maraca includes habitats ranging from rainforests and semi-deciduous forests to natural savannahs, lakes, and palm swamps.  This pristine environment is home to a wide-range of plants, trees, mammals, reptiles and fishes, undisturbed by man’s environmentally destructive progress .
