Prior to the introduction of cropping, Ubombo was an extensive cattle ranch. A remnant of 9 361 hectares of the ranch land now remains as natural bush.
In 1986 a portion of 300 hectares adjoining the Van Eck Dam was set aside to be a wildlife sanctuary and named Mhlosinga Nature Reserve. The aim of Mhlosinga was to preserve a piece of the magnificent Swaziland bushveld and restore it, so far as possible, to its unspoilt state. The portion was game fenced and patrolled and various species on non-dangerous game were re-introduced into Mhlosinga. Mhlosinga was so successful and popular that over the years additional areas were added to the reserve. Today the reserve stands at 1 850 hectares in extent and now completely surrounds the strategically important Van Eck Dam. The environment has stabilised with an increasinghealthy and diverse population of wild animals. Over the past few years we have carried out aerial counts. The chart below shows the population of the wild animals found in the reserve (taking into account death, birth , poaching and controlled harvesting).
