The landscape of the shire is characterised by undulating sandplain, valley floors and alluvial flats and a salt lake chain associated with an ancient drainage system.
The shire is located within the Tallering (YAL02) and Merredin (AVW01) IBRA sub-regions and is characterised by low open woodlands and proteaceous scrub. One Priority Ecological Community occurs in the shire – the Red Morrell Eucalyptus longicornis woodland of the Wheatbelt.
