Underlying the Shire of Dalwallinu is south west terrain which forms a part of the Yilgarn Craton. The area comprises of granite rock, gneissic banding and minerals rich in iron and magnesium.
The soils underlying the Shire of Dalwallinu includes loamy calcareous earthy soils, deep sandy and sandy earth soils, of yellow deep sand, yellow and brown sandy earths. Sodic subsoils of loamy and red loamy duplexes also occur in the area. The eastern portion of the shire is characterised by undulating sandplain, valley floors and a salt lake chain associated with an ancient drainage system. Emerging from the landscape are lateritic outcrop and broad sandy gravelly ridges. The western portion of the shire comprises of valley floors, salt lake chains and alluvial flats associated with an ancient drainage line, which is surrounded by undulating plain of sand dune and rises with long gentle gradients on weathered granite

IBRA Regions
Tallering sub-IBRA
The Tallering sub-IBRA forms part of the Yalgoo IBRA. The Yalgoo IBRA is dominated by red sandy plain of low woodlands to open woodlands of Eucalyptus, Acacias and Callitris (Desmond and Chant, 2001d).
Ancient Drainage subregion (Avon Wheatbelt 1)
The Ancient Drainage subregion occurs in the eastern LGAs of the NAR. This subregion is characterised by Proteaceous scrub occupies much of the lateritic hills and outcrops. The alluvial plains associated with the drainage lines is dominated by eucalypts, Casuarinas, York Gum and Jam wattle woodlands (Beecham, 2001a).
Threatened Ecological Communities
Priority Ecological Communities
Red Morrel Woodland of the Wheatbelt
Tall open woodlands of Eucalyptus longicornis (red morrell) found in the Wheatbelt on lateritic, ironstone or granitic soil types. Sometimes found with Eucalyptus salmonophloia (Salmon Gum), or E. loxophleba (York Gum) woodlands and has very little understorey. It is also found directly above lake systems in the central and eastern Wheatbelt. The landscape unit in which it is found is valley floors, usually adjacent to saline areas.

Moore Catchment CouncilMoore Catchment Council is a non-for profit, community body elected to represent the community’s interest in Natural Resource Management issues. The sub-region includes Shires in the Northern Agricultural Region that are directly associated with the Moore River catchment and drainage system – an area covering approximately 14 000 square kilometers, from Perenjori in the north east to Gingin in the south, where the River meets the Indian Ocean at Guilderton.
The philosophy of the Moore Catchment Council is to protect and continue to enhance the natural resources of the area for future generations. The role of the Council is to promote integrated catchment management and co-ordinate efforts to ensure effective on-ground action, along with sourcing funding to implement community prioritised strategies.
