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.

Description: Carnaby's Black Cockatoo (CBC) confirmed Roost sites buffered. A confirmed site is a site where CBC were recorded roosting as part of a formal roost survey (using the Great Cocky Count method in which birds are recorded as they settle, 30 minutes either side of sunset), as described by Berry (2008). Buffering was done to cover roost movement and recording accuracy. Roosts were buffered to 6km to indicate the likely feeding area of the roost. This layer should be used in conjunction with associated feeding, breeding and roosting data layers described in the Methods for Mapping Carnaby's Cockatoo Habitat report.

Description: This is one layer of a set of GIS data layers that show the currently known confirmed and unconfirmed night roost areas of Carnaby's Black Cockatoo (CBC) in the South-West of Western Australia. The point data is from data held by DEC and is primarily the 2006 and 2010 Great Cocky Count project (Burnham et al. 2010) plus some observations brought to the attention of DEC. This particular layer here is for the "Confirmed Roost" category. A “Confirmed Roost” is a site where CBC were recorded roosting as part of a formal roost survey (using the Great Cocky Count method in which birds are recorded as they settle, 30 minutes either side of sunset), as described by Berry (2008). An “Unconfirmed Roost” is a site where roosting CBC have been reported to Birds Australia or DEC but have not had a positive count recorded during any official survey. Roosts of either category were buffered to 500 and 1000m for small and large (>150 birds) roosts, respectively. This buffering was done to cover roost movement and recording accuracy. See the asssociated methods document for more detail. Roosts were also buffered to 6km to indicate the likely feeding area of the roost. It should be noted that most surveys occur near human habitation and hence it is likely that there are roosts outside of those indicated in the GIS data layer. A GIS data layer is available (in this set) to indicate the well surveyed area. There are known issues or concerns with this data layer which are described in the supporting methods document. The data layer can be used to guide decision making for Carnaby's black cockatoo, however assessment and mapping in greater detail may be needed before planning decisions can be made about specific areas.

Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This is one layer of a set of GIS data layers that show the currently known confirmed and possible breeding areas of Carnaby's Black Cockatoo (CBC) in the South-West of Western Australia. The particular layer here is for the confirmed category, where chicks or eggs of CBC have been observed. It has been clipped to the sum of the SCP and Jarrah Forest IBRA regions. The breeding areas beyond these IBRA regions have been placed in another GIS layer so they may also be considered. The final data layer of the breeding set is of possible breeding areas. All areas were obtained by 12 km buffering or extension of site points. It should be noted that these data are obtained from projects developed for a variety of purposes and hence likely that there are breeding areas outside of those indicated in the GIS data layer. This possibility increases the further the distance from human habitation and roads.

Description: Sites where Black-Cockatoos (generally Carnaby’s) are confirmed to be breeding. Breeding is inferred based on surveys which have recorded either birds entering/leaving the nest or the inside of the nest has been viewed with eggs or chicks. These records are of breeding attempts, but not necessarily of successful fledging. The first surveys were in 2003, with some nests surveyed a single time and others revisited once a year. Most records are in the peak breeding season of Carnaby’s (September to January). Breeding sites are buffered to 2 Kilometres.

Description: Data from The Great Cocky Count which takes place annually in early to mid-April. This event records birds as they fly in to night roosts on a single day and has taken place since 2010. Three species are recorded: Carnaby’s and Baudin’s (white-tailed) and Forest Red-tailed Black-Cockatoos. In the Perth-Peel Coastal Plain all white-tailed are assumed to be Carnaby’s. In other areas the roosts could include either species or both, so a generic ‘white-tailed’ term is used. Roosting sites have been buffered to I Kilometre.
