W National Park is shared by Niger, Upper Volta and Benin, and is recognized as being one of the most important parks in West Africa by virtue of its size—11,320 sq km—and its diversity of habitats and species*. Both its proximity to the rapidly growing capital of Niamey, Niger, and the burgeoning trans-Saraha tourist traffic give it great tourist potential. The park and its wildlife, however, are under constantly increasing pressure from poaching, illegal grazing, uncontrolled bush fires, the possibility of phosphate mining, and the lack of financial and material means to combat these problems. The author is a US Peace Corps biologist who worked in Niger for four years, for part of the time attached to the IUCN/WWF aridlands project. He describes conditions and problems in the Niger sector of W National Park and discusses possible solutions.
