Galloway No. 1 Inland Saline Wetland Complex
- Description: Saline site on high terraces on true left of the Manuherikia River at the southern end of the Raggedy Range. The site contains a fully representative Lepidoptera fauna of saline soils and salt tolerant vegetation of Centre Otago. Several uncommon insects occur, feeding on the salt tolerant plants. A rare species of grasshopper is found on the rocky ground above the saline area.

Other Information:
- Soil classified as Saline Immature Semiarid Soil. 8
- Halophytes present include Atriplex buchananii with a threat status of naturally uncommon, Hordeum spp., Puccinellia raroflorens which has a threat status of nationally critical, and salt grass (Puccinellia fasciculata). 8
- Invertebrate species recorded include Athrips zophochalca, Eurythecta zelaea, Heliothis sp. nov., Kiwaia thyraula, Loxostege sp. nov., Orocrambus corruptus, Paranotoreas fulva, Scoparia exilis, Scopula rubraria and Sigaus minutes.

- The Department of Conservation considers the Galloway No. 1 Inland Saline Wetland Complex to be a highly important site for biological conservation. On a scale from 1 (highest value) to 11 (lowest value) the site was given a rank of 2, 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 include dumping of rubbish, fire, fertiliser application, oversowing, and invasion of exotic plants. It is also recommended that erosion be monitored. 8
- A key site for Lepidoptera, Acrididae and Cicadidae conservation in the Manorburn Ecological District. 24
- Listed as an Area of Significant Indigenous Vegetation, Habitats of Indigenous Fauna and Wetlands in the Central Otago District Plan. 55
