Description: Western Australia has a rich and largely unique biodiversity. Areas of this State are among some of the most diverse in the world but vast amounts of native vegetation have been cleared to make way for agriculture and urban development. In some areas of the Wheatbelt, more than 90 per cent of the native vegetation has been cleared, with the flow-on effect being loss of animal habitat and connectivity between the remaining remnant vegetation. As a consequence, the roadside remnants now fulfil a very important function in linking a fragmented landscape and enhancing wildlife dispersal. Roadside vegetation also meets other important roles such as: • mitigation against erosion and soil drift; • shelter for adjoining properties; • material for revegetation; • wildflower tourism; and • a sense of place or local identity for the local community. In 1989, the Roadside Conservation Committee (RCC) initiated a method of surveying roadsides for their conservation values. The survey program is ongoing and aims to assist Shires and communities in the protection, maintenance and improvement of roadside vegetation. In order to effectively manage and conserve roadside corridors, it is vital that road managers are aware of the conservation status and regional significance of roadsides under their control. For this to be achieved, roadside vegetation in Western Australia should be assessed and mapped. Geographic Information Systems (GIS) provide a powerful and useful method of mapping data collected from roadside inventories and this can be utilized by all agencies and community groups with an interest in roadside values. In Western Australia, the managers of roads and road verges are Main Roads Western Australia (MRWA), Local Government and DEC. The roadside survey records a number of attributes, such as width, diversity of vegetation, number of native species present, extent of weed cover and adjoining land use. These characteristics are scored to produce a roadside conservation value (RCV) for that section of road. The resulting map shows the pattern of roadside conservation values (high, medium high, medium low, low) and how those values vary across a district. The scores are used by road managers to establish which areas need priority attention or protection. The survey results can be used in the following ways: • to target weed control, • as a general roadside inventory, • to protect wildlife corridors, • to promote significant wildflower areas, historical and cultural sites for tourism, • to plan roadside maintenance activities, • to target strategic revegetation. For SLIP display purposes the road lines have been copied 5 metres to the left and right of the original road with the original road line removed. Left road lines have been attributed with values of 0 for the RCV_RIGHT field and right road lines have been attributed with values of 0 for the RCV_LEFT field. Some shires have been surveyed more than once and the most recent data is included. For information on previous surveys contact the Roadside Conservation Committee (RCC).

Description: Tuart occurs in a coastal strip from near Jurien to the near Busselton in Western Australia. Most have been cleared for agriculture and urban development. Since the mid-1990s there has also been a marked decline in the health and vitality of tuart trees at Yalgorup between Mandurah and Bunbury. The purpose of the Tuart Atlas is to provide accurate and current information on (i) the extent of remnant tuart woodlands over it natural range, (ii) the density of its overstorey component, and (iii) the condition of it associated understorey

Description: This is an approach to conservation planning that systematically identifies the highest priority biodiversity values and conservation areas that, combined, can achieve the most effective and efficient goals. These areas can include private land. Explicit targets are often set for the conservation of particular biodiversity values or features, such as species, vegetation or wetland types.
