The Modderfontein Reserve, the biggest private open space in Gauteng, has been opened to the public on 20 Sept 2012 to picnic, cycle, bird-watch and enjoy the game of the reserve. The Modderfontein Reserve, which is located in Modderfontein in Johannesburg, is operated by the Endangered Wildlife Trust (EWT) on a day-to-day basis. The land it is situated on belongs to chemicals group AECI and forms part of its 2 400ha Modderfontein landholding. Various fauna and flora studies are currently being conducted to record animal and plant species in the reserve and a monitoring system is being implemented which will allow the EWT team to record changes at fixed points throughout the reserve over time. Mammals on the site include small buck such as steenbok, as well as black-backed-jackals. A bat survey has already been carried out and studies on the bats are ongoing. Fish eagles and long-crested eagles are among the bird life in the Modderfontein Reserve.
The community will have access to the Modderfontein Reserve at a cost of R30 per adult and R15 for children and pensioners.
