egional processes”. Existing and artificial barriers such as roads and drains were also expected to beimpacting on drainage and subsurface flows at the saline site.The Environmental and Earth Sciences (2007) report includes information from Department of Landand Water Conservation’s (DLWC) Central West Groundwater Data (2002) which reveals that waterbearing zones were typically located between 15 and 35m in fractured rock in bores drilled withinthe vicinity of Mudgee Area 2.Aside from the saline site within Mudgee Area 2, the remainder of the area surveyed byEnvironmental and Earth Sciences (2007) was found to be well vegetated with perennial pastures,native grasses, and/or lawns with no evidence of salt accumulation on the surface, and no erosion.The Soil Landscapes of the Dubbo 1:250 000 Sheet Map (1998) identifies soils within the subject areaas Craigmore (cm). According to the associated report, the Craigmore soils are generally Non-calcicBrown Soils and Red Earths with isolated low levels of salinity occurring along some drainage linesand depressions. Parent materials are quaternary alluvium and eluvium, sand, silt clay and somegravel.A summary of the main soils of the Craigmore soil landscape are contained in Table 1: Summary ofthe Main Soils of Craigmore Soil Landscape.PRELIMINARY SOIL SALINITY ASSESSMENT4
