Independent Namibia has an excellent conservation track record, based on a sound legislative framework and pragmatic sustainable-use approaches. This has enabled healthy populations of most of the historically occurring wildlife in areas of suitable habitat. Namibia’s elephant population is at its highest in more than a century. The country is home to the largest population of black rhinos in the world, and the second-largest population of white rhinos. Wildlife is one of Namibia's most valuable natural resources.
