ECO PRESERVATION SOCIETY wrote -The project involves the restoration of a biological corridor between the Naranjo River and the Savegre River, on the central pacific coast of Costa Rica. When completed, the corridor will serve as a vital link for wildlife in the Manuel Antonio National park. When completed, the corridor will provide relief for many endangered species, including the highly endangered Mono Titi squirrel monkey. Not an easy undertaking. The project requires removing and reversing the negative effects of non-native plants, such as deep-rooted grasses, sea almond and coconut palms. Then natural mangrove colonies must be re-established, using native varieties of mangrove, ferns and other salt-tolerant species. Ultimately, a biological corridor connecting the two separate Mono Titi habits would spare the monkeys from extinction and provide additional habitat for other indigenous Costa Rican animals.
