Heritage listings Cleve has a number of heritage-listed sites, including: Cleve-Cowell Road: Sims Farm Homstead off Cleve Road: Yeldulknie Cottage off Cleve Road: Yeldulknie Weir Geography Cleve is located in the central east Eyre Peninsula, a large triangular body of land in South Australia. Many of the areas geological and geographical features are responsible for the use of the land and types of natural vegetation present. The landscape has been heavily modified since European settlement and now is predominantly farming land, with patches of native scrub in places. The Cleve Hills are a major topographical feature of the region and have areas of preserved vegetation in their bounds. Geology and Pedology The town of Cleve lies on an ancient bedrock that has undergone high grade metamorphism, with the area characterised by schists, gneisses and granites in a formation known as the Hutchison Group. These strata were laid down in the Proterozoic, some 600-2300 million years ago. The area underwent deformation during the orogeny events that shaped Australia. Just south of Cleve marks an unconformity with recent Quaternary alluvial and colluvial sediments of the Piedmont Group which were deposited less than 1 million years ago. The soils around Cleve are heavily tied to the geology of the area, with Cleve having a clay overlain by sandy loam soils in the hills and on most slopes in the area. This soil is often referred to as 'Cleve soil' or 'Nobby's Hill's soil'. The soils are highly productive when they are deep enough to hold enough moisture, but are particularly susceptible to erosion, especially in steeper inclines. There is also a strong calcareous component to much of the areas soils, especially away from the slopes. Climate Cleve experiences a hot-summer mediterranean climate (Köppen: Csa, Trewartha: Csbl); with warm, dry summers; mild to warm, relatively dry springs and autumns; and mild, moderately rainy winters. The rainfall is generally not enough to cause any flooding, and certainly not within the bounds of the town. The Cleve hills, however are the catchment areas for Salt Creek, and localised flooding in the valleys has been reported. Flora and Fauna The most common vegetation association in the area is classified as Open Scrub (Mallee/Broombush), which is typical of most of the mid eastern Eyre Peninsula, consisting of Eucalyptus socialis (summer red mallee), Eucalyptus incrassata (ridge fruited mallee) and Eucalyptus leptophylla (narrow-leafed mallee), with a Melaleuca uncinata (broombush)
