The Koko Nature Reserve is a massive island (larger than Australia) nature reserve off the coast of South America and Central America. Almost all parts or the island is dominated by scrublands, temperate grasslands, fern prairies, temperate forests, highlands, rocky mountains, subtropical forests, and swamps similar to South America during the Early to Late Cretaceous period. The island was born from Island customization in 2 million years ago by time travelers to recreate the lost Cretaceous habitats and species without affecting the mainland habitats or species.
