STREAM STUDY

The Southern Bell Frog, scientifically known as Litoria raniformis, is an amphibian found in wetlands and coastal areas. It exhibits significant color changes from green to brown during the breeding season. Native to Australia, it was introduced to New Zealand in the 1860s and has adapted well to various habitats, including streams and woodlands. However, it faces threats like habitat loss, disease, and predators. Sighted at Cape Palliser on February 15, 2014, conservation efforts are crucial for its survival.
