Other Information:
- Soil classified as Saline Immature Semiarid Soil. 8
- Other plant species found include Atriplex buchananii (threat status of naturally uncommon), Hordeum spp., Buck’s-horn plantain (Plantago coronopus), Puccinellia raroflorens (threat status of nationally critical), salt grass (Puccinellia fasciculata), salt grass (Puccinellia stricta) and Selliera microphylla. 8
- Invertebrate species recorded include Arctesthes catapyrrha, Capua semiferana, Eurythecta zelaea, Kiwaia thyraula, Orocrambus corruptus and Paranotoreas fulva. 8 The small field cricket Nemobius sp. has also been recorded at this site. 44
- The Department of Conservation considers the Moa Creek Inland Saline Wetland to be a moderately important site for biological conservation. On a scale from 1 (highest value) to 11 (lowest value) the site was given a rank of 5, on the basis of its geographical extent, relative representativeness (the extent to which the site represents the assumed 1840 condition), diversity and rarity of biota and soils. 8
- Potential threats to the site include irrigation, cultivation, fertiliser application, oversowing, invasion by exotic weeds, grazing and trampling by stock. 8
- Large sarsen stones found at this site have prevented ploughing. 44
- Other moth species found are Kiwaia lenis, Scythris n.sp., Paranotoreas fulva and Loxostege n.sp. 45
- Listed as an Area of Significant Indigenous Vegetation, Habitats of Indigenous Fauna and Wetlands in the Central Otago District Plan. 55
