It gives us great pleasure to present this new App for Lemur-Watching; the first of its kind ever produced. This App is based on the third and fourth editions of Lemurs of Madagascar, with updates since the most recent of these, the French version, was published in 2014. As you will see, one of the main purposes of this App is to stimulate Lemur Ecotourism in the form of Lemur-Watching and Lemur Life-Listing, part of a global effort to stimulate Primate Ecotourism worldwide.
