Yobarnie is of state heritage significance as the earliest and still legible evidence of the techniques and systems pioneered by PA Yeomans for soil improvement, water storage, cultivation and irrigation on undulating topography. In addition to the increased fertility and productivity of the soil subjected to the Keyline regime, by-products of the system include erosion prevention, increased fire safety, significant carbon sequestration and improved wildlife habitat. The distinctive cultural landscape resulting from this technical achievement is itself aesthetically pleasing and offers considerable scope for contributing to the visual and recreational amenity of any future adaptive reuse.
