This system consists of Native Pine Woodlands (Callitris gracilis) and Mallee Box mallee/woodlands (Eucalyptus porosa).
These species primarily occur on shallow limestone & rocky soils and have patchy and sparse distribution due to a history of vegetation clearance, heavy grazing, inappropriate fire regimes and the pressure of introduced herbivores.
Native Pine and Mallee Box Woodlands are scattered throughout the project area but primarily in the Venus to Streaky Bay region with Mallee Box growing on heavier loamy soils in flat depressions with degraded understorey vegetation in many areas.
Approximately 23% of the mallee box present on Eyre Peninsula has been mapped and protected within Heritage Agreements and Conservation Parks within the WildEyre area.
Mallee Box develops hollows that may be critical habitat for fauna species such as Western Pygmy-possums (Cercartetus concinnus). The Malleefowl (Leipoa ocellata) is a species that depends on large, intact and long-unburnt mallee systems.
It has been shown that mallee communities supports high levels of reptile diversity, with species using the leaf litter, trees and hollows for foraging and shelter. The Bicycle Dragon (Ctenophorus cristatus) is primlarily found in mallee. The main groups of reptiles commonly associated with mallee systems include:
- Geckos (Gekkonidae)
- Snake Lizards (Pygopodidae)
- Dragon Lizards (Agamidae)
- Venomous land snakes (Elapidae)
- Stock rabbit and kangaroo grazing
- Weed invasion
- Altered fire regime and intensity
- Clearance for human development and agriculture
