The major threat to this species is its severely fragmented distribution. It has undergone a decline in its range, most likely as a result of urbanization. This threat has been inferred from maps showing an overlap of urban areas with the range of this species. Urban development is still ongoing in some of its range (N. Doran pers. comm. 2009). Furthermore, broad scale habitat change and changes in weather, water and drainage patterns due to climate change could become a major issue in the future (N. Doran pers. comm. 2009).
