Habitat and Ecology
This species occupies indigenous fynbos heathland vegetation and can be found in dense restios stands in close proximity to seepages. The area it occupies is under threat from alien vegetation and too frequent fires and has an ongoing decline in quality. It is a direct developing species laying around 10 eggs like other members of the genus.
The main threats to this species are fires which cause extreme population fluctuations and have a synergistic effect on alien invasive plants which are degrading and drying seepages. Both threats are extensive and severe on the entire distribution of this species.
Identification of impact of threats and their management is seen as a key area of research for the conservation of this species. An invasive alien plant clearing plan for the site is a priority and is being developed by CapeNature and private land owners. This and other members of the genus require more information on life history, dispersal and population size to be followed by monitoring.
This species was recently described by Turner & Channing (2008).
