PROJECT 4 - Narrogin Link Road Stage 2 South (decision date of 25 August 2014).
 
The approved offset involved the provision of funds for the acquisition of 5.8 hectares of native vegetation containing similar environmental values to those being lost through the approved clearing.
 
The size of the offset required was determined using the Commonwealth Offsets Assessment Guide.
 
With the funds provided a total of 5.8 hectares of remnant native vegetation has been purchased. The vegetation occurs across five adjoining lots totaling 407.4 hectares, each entirely covered by remnant native vegetation. The difference of 401.6 hectares was funded through offset fund contributions received as a result of clearing permit conditions imposed on three other Main Roads Western Australia projects:
1. CPS 818/11 - York Merredin Road - SLK 51 to 66 - widening and Dangin Mears Road intersection upgrade - 30.86 hectares
2. CPS 818/12 - Narrogin Link Road Stage 3 North - 4.8 hectares
3. CPS 6800/1 - York Merredin Road - SLK 1.95 to 51 - widening - 365.94 hectares
Note: The offset area displayed in the map is that of the entire 407.4 hectares (i.e. all five lots).
 
Based on information obtained from a site inspection undertaken by Department of Environment Regulation officers, it is considered that the five lots contain the following environmental values:
- suitable foraging, nesting and roosting habitat for black cockatoos;
- suitable foraging and breeding habitat for red-tailed phascogale;
- approximately 278 hectares of vegetation representative of the threatened ecological community Eucalypt Woodlands of the Western Australian Wheatbelt; and
- vegetation significant as a remnant in an area that has been extensively cleared (the vegetation is mapped as Beard vegetation association 946 which retains approximately 19 per cent of its pre-European extent in the Avon Wheatbelt bioregion).
 
The majority of the vegetation is dominated by Eucalyptus wandoo and was considered to be in very good condition or better based on the Keighery (1994) scale. Large trees with hollows were observed regularly. Potential evidence of black cockatoo foraging on Banksia prionotes was also observed and black cockatoo calls were heard from nearby vegetation.
 
Given the above, the offset is considered to be relevant and proportionate to the significance of the environmental values being impacted, counterbalancing the residual impacts of the project.
 
Note: A portion of the funds provided remains unspent. Upon expenditure, further details will be published.

PROJECT 5 - Margaret River Perimeter Road Stage 1 (decision date of 6 November 2014)
 
The approved offset involved the provision of a monetary contribution of $65,360 for the acquisition of 4.3 hectares of remnant native vegetation containing black cockatoo habitat values for inclusion in the conservation estate. The area to be acquired was calculated using the Commonwealth Offsets Assessment Guide.
 
With the funds provided, a portion of Lot 224 on Plan 2087, Nambeelup (now Lot 401 on Deposited Plan 405854, Nambeelup) was purchased for conservation. Lot 401 is approximately 83 hectares in size and contains approximately 70 hectares of remnant native vegetation. The vegetation present is, for the most part, a woodland dominated by Eucalyptus marginata, Allocasuarina sp. and Banksia spp. The property also includes a section of the Nambeelup Brook including associated riparian vegetation. The majority of the vegetation is estimated to be in very good (Keighery 1994) condition.
 
The vegetation present on Lot 401 includes suitable foraging, roosting and nesting habitat for Carnaby's cockatoo, Baudin's cockatoo and forest red-tailed black cockatoo. The vegetation is mapped as Bassendean Complex Central and South which retains 26 per cent of its pre-European extent. The vegetation is considered to represent significant remnant vegetation in an area that has been extensively cleared. The vegetation is also considered to form ecological linkages with surrounding remnant vegetation.
 
The funds provided enabled 5.66 hectares of the 70 hectares of remnant vegetation to be purchased. Offsets Fund contributions received as a condition of the following clearing permits were also used to acquire Lot 401:
- CPS 5207 Ellenbrook Management Pty Ltd (0.52 hectares)

- CPS 185/6 Water Corporation Baldivis DN1400 Outlet Tamworth (2.97 hectares)
 
Note: The offset boundary displayed is that of the entire of Lot 401.
 
Given the above, the offset is considered relevant and proportionate to the significance of the environmental values being impacted, counterbalancing the significant residual impacts of the clearing.

PROJECT 6 - Margaret River Perimeter Road Stage 2 (decision date of 6 November 2014)
 
The approved offset involved the provision of a monetary contribution of $372,400 for the acquisition of 22.3 hectares of remnant native vegetation containing black cockatoo habitat values, and 2.2 hectares of remnant native vegetation containing western ringtail possum habitat values (i.e. a total of 24.5 hectares), for inclusion in the conservation estate. The area to be acquired was calculated using the Commonwealth Offsets Assessment Guide.
 
With the funds provided, portions of the following three properties totaling 31.7 hectares were purchased for conservation:
- Lot 401 on Deposited Plan 405854, Nambeelup (formerly part of Lot 224 on Plan 2087, Nambeelup) (27.16 hectares)
- Lots 217 and 218 on Plan 4918, Vasse (1.93 hectares)
- Lot 4470 on Plan 29854, Karridale (2.61 hectares)
 
Lot 401 contains remnant vegetation with black cockatoo habitat values, Lots 217 and 218 contain remnant vegetation with western ringtail possum habitat values, and Lot 4470 contains remnant vegetation with both black cockatoo and western ringtail possum habitat values.
 
Given the above, the offset is considered relevant and proportionate to the significance of the environmental values being impacted, counterbalancing the significant residual impacts of the clearing.
 
The following provides a more detailed description of each property.
 
Lot 401 is approximately 83 hectares in size and contains approximately 70 hectares of remnant native vegetation. The vegetation present is, for the most part, a woodland dominated by Eucalyptus marginata, Allocasuarina sp. and Banksia spp. The property also includes a section of the Nambeelup Brook including associated riparian vegetation. The majority of the vegetation is estimated to be in very good (Keighery 1994) condition.
 
The vegetation present on Lot 401 includes suitable foraging, roosting and nesting habitat for Carnaby's cockatoo, Baudin's cockatoo and forest red-tailed black cockatoo. The vegetation is mapped as Bassendean Complex Central and South which retains 26 per cent of its pre-European extent. The vegetation is considered to represent significant remnant vegetation in an area that has been extensively cleared. The vegetation is also considered to form ecological linkages with surrounding remnant vegetation.
 
The funds provided enabled 27.16 hectares of the 70 hectares of remnant vegetation on Lot 401 to be purchased. Offsets Fund contributions received as a condition of the following clearing permits were also used to acquire Lot 401:
- CPS 5207 Ellenbrook Management Pty Ltd (0.52 hectares)
- CPS 5304 The Roman Catholic Archbishop of Perth (2.16 hectares)
- CPS 5487 The Roman Catholic Bishop of Bunbury (5.44 hectares)
- CPS 5759 Capricorn Investment Group Pty Ltd & Yanchep Sun City Pty Ltd (2.16 hectares)

- CPS 185/6 Water Corporation Baldivis Sewage Pump Station to East Rockingham Wastewater Treatment Plant Pressure Main (8.81 hectares)
- CPS 185/6 Water Corporation Baldivis DN1400 Outlet Tamworth (2.97 hectares)
Note: The offset boundary displayed for Lot 401 is that of the entire of Lot 401.
 
Lots 217 and 218 are each approximately 8.1 hectares in size and contain a combined total of approximately 4 hectares of remnant native vegetation. The vegetation present is dominated by Melaleuca rhaphiophylla, Melaleuca viminea, Melaleuca osullivanii, Eucalyptus rudis and Agonis flexuosa. The lots also contain areas of wetland and are located adjacent to the Broadwater Nature Reserve. The majority of the vegetation is estimated to be in degraded (Keighery 1994) condition. The vegetation present includes suitable western ringtail possum habitat. With the funds provided, 1.93 hectares of vegetation across Lots 217 and 218 was purchased.
Note: The offset boundary displayed for Lots 217 and 218 is the 1.93 hectares purchased.
 
Lot 4470 is approximately 197.4 hectares in size and contains approximately 114.5 hectares of remnant vegetation. The vegetation present comprises of 58.1 hectares of wetland vegetation and 56.4 hectares of upland remnant vegetation consisting of jarrah and marri.
 
The vegetation on Lot 4470 includes foraging and possibly nesting habitat for Carnaby's cockatoo, Baudin's cockatoo and forest red-tailed black cockatoo. The vegetation on the property also includes suitable habitat for the western ringtail possum, and core habitat for another critically endangered fauna species. All three black cockatoo species and the western ringtail possum have been recorded on neighbouring properties within similar habitat.
 
The vegetation is considered to represent significant remnant vegetation in an area that has been extensively cleared with the wetland vegetation representing 6% of the remaining extent (less than 1000 ha) of the Glenarty Hills wet (Hw) vegetation complex. The vegetation is also considered to form ecological linkages with surrounding remnant vegetation including areas already reserved for conservation. It follows that the vegetation is considered to contain a high level of biodiversity.
 
The funds provided enabled 2.61 hectares of the 114.5 hectares of remnant vegetation on Lot 4470 to be purchased. Offset Fund contributions received as a condition of the following clearing permits were also used to acquire Lot 4470:

PROJECT 9 - Albany Highway SLK 242.4 to 248.4 - upgrade north of Kojonup (decision date of 3 April 2014).
 
The offset includes the establishment of 1.65 hectares of native vegetation using species consistent with Beard Vegetation Association 4. This includes the establishment of at least 200 potential Carnaby's cockatoo, Baudin's cockatoo and forest red-tailed black-cockatoo habitat trees per hectare.
 
The offset is expected to establish native vegetation in as good as, or better condition, than the cleared area. The offset is also expected to contain a substantially greater number of potential Carnaby's cockatoo, Baudin's cockatoo and forest red-tailed black-cockatoo habitat trees than the cleared area.
 
Given the above the offset is considered relevant and proportionate to the significance of the environmental values being impacted, counterbalancing the residual impacts of the project.

PROJECT 10 - York Merredin Road - SLK 51 to 66 - widening and Dangin Mears Road intersection upgrade (decision dates of 25 August 2014, 21 July 2015 and 27 October 2017)
 
The approved offset involved the provision of funds for the acquisition of 12.38 hectares of native vegetation containing similar environmental values to those being lost through the approved clearing.
 
The size of the offset required was determined using the Commonwealth Offsets Assessment Guide.
 
With the funds provided a total of 30.86 hectares of remnant native vegetation has been purchased. The vegetation occurs across five adjoining lots totaling 407.4 hectares, each entirely covered by remnant native vegetation. The difference of 376.54 hectares was funded through offset fund contributions received as a result of clearing permit conditions imposed on three other Main Roads Western Australia projects:
1. CPS 818/11 - Narrogin Link Road Stage 2 South - 5.8 hectares
2. CPS 818/12 - Narrogin Link Road Stage 3 North - 4.8 hectares
3. CPS 6800/1 - York Merredin Road - SLK 1.95 to 51 - widening - 365.94 hectares
Note: The offset area displayed in the map is that of the entire 407.4 hectares (i.e. all five lots).
 
Based on information obtained from a site inspection undertaken by Department of Environment Regulation officers, it is considered that the five lots contain the following environmental values:
- suitable foraging, nesting and roosting habitat for black cockatoos;
- suitable foraging and breeding habitat for red-tailed phascogale;
- approximately 278 hectares of vegetation representative of the threatened ecological community Eucalypt Woodlands of the Western Australian Wheatbelt; and
- vegetation significant as a remnant in an area that has been extensively cleared (the vegetation is mapped as Beard vegetation association 946 which retains approximately 19 per cent of its pre-European extent in the Avon Wheatbelt bioregion).
 
The majority of the vegetation is dominated by Eucalyptus wandoo and was considered to be in very good condition or better based on the Keighery (1994) scale. Large trees with hollows were observed regularly. Potential evidence of black cockatoo foraging on Banksia prionotes was also observed and black cockatoo calls were heard from nearby vegetation.
 
Given the above, the offset is considered to be relevant and proportionate to the significance of the environmental values being impacted, counterbalancing the residual impacts of the project.
 
Note:
- A portion of the funds provided remains unspent. Upon expenditure, further details will be published.
- Amendments to the approved clearing boundaries were approved on 21 July 2015 and 27 October 2017. These amendments did not result in any change to the amount of clearing approved. The amendments also did not result in an increase to the significant residual impacts assessed for the original version of the clearing boundaries approved 25 August 2014.
