In December 1902, Leonard Ledeboer, a Zoutpansberg resident who had switched sides during the war, suggested the establishment of a reserve to sir Godfrey Lagden of the Department of Native Affairs. The Administrative Proclamation No. 19 of May 1903 which established the Singwitsi Reserve, also brought an end to the lawless exploitation of the region. The reserve boundary went from the Groot and Klein Letaba confluence in a straight line north to Shikumdu Hill, turning northeastwards to the Levuvhu and Crook's Corner. From the Limpopo it ran south along the Portuguese border to the Olifants, and west along the Letaba to the aforementioned confluence. The remote and beautiful reserve could boast with hills topped by baobab trees, dramatic gorges, including Lanner Gorge, lush riparian vegetation, plains with impressive mopane trees, and flood plains adorned with ilala palms and fever trees.
