Madagascar is one of the earth's top conservation priorities, with over 80% of its plants and animals found nowhere else, forests that have already provided treatment for leukemia, and habitats that are rapidly being burned. Formed in 1988 at the request of the Malagasy government, the Madagascar Fauna Group unites zoos, botanical gardens, aquariums, and universities in North America, Europe, Africa, and Australia in an effort to save Madagascar, its people, its wildlife, and its future. Its programs include a Saturday School that helps local children pass the exam required to enter secondary school, along with programs for older students and teacher training. Madagascar is also home to about half of the world's chameleon species, including both the largest and smallest, and Madagascar Fauna Group staff conduct long-term reptile surveys in the Betampona reserve while other scientists have used known population information and NASA satellite data to predict locations of other populations, leading to the discovery of new reptile species.
