Gazetted in 2005, it encompasses a preserved ecosystem including the former Saadani game reserve, the former Mkwaja ranch area, the Wami River as well as the Zaraninge Forest. In the late 1960s Saadani Village – the village after which the park has been named – and particularly its sub-village Uvinje, invited the Tanzania Wildlife Division (WD) to help them to prevent the indiscriminate killing of wildlife prevalent in the area. From this partnership Saadani village and the Wildlife Division established the Saadani Game Reserve (SGR), with the agreement to respect the land rights of the coastal sub-villages of Saadani, including Uvinje and Porokanya sub-villages, while also addressing the needs of wildlife.
