This offset involves the rehabilitation of 2.3 hectares of land to re-establish/enhance the following environmental values at the offset site:
- ecological linkage values;
- black cockatoo habitat;
- western ringtail possum habitat; and
- vegetation significant as a remnant within an extensively cleared area.
 
The rehabilitation will re-establish/enhance environmental values similar to that lost. The size of the offset required (counting both this rehabilitation offset and the land acquisition offset) was determined using the Commonwealth Offsets Assessment Guide. A mitigation credit was also applied to account for rehabilitation of portions of the clearing area.

This offset involves the provision of a monetary contribution of $126,000 for the acquisition of 18 hectares of remnant native vegetation containing similar environmental values to that to be cleared, for inclusion in the conservation estate. The area to be acquired was calculated using the Commonwealth Offsets Assessment Guide, taking into account the size of the rehabilitation offset as well as a mitigation credit for rehabilitation of portions of the clearing area.
 
With the funds provided, a portion of Lot 224 on Plan 2087, Nambeelup (now Lot 401 on Deposited Plan 405854, Nambeelup), and portions of Lots 218 and 219 on Plan 4918, Vasse, were 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 5.44 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 5759 Capricorn Investment Group Pty Ltd & Yanchep Sun City Pty Ltd (2.16 hectares)
- CPS 818/11 Main Roads Western Australia (MRWA) Margaret River Perimeter Road Stage 1 (5.66 hectares)
- CPS 818/11 MRWA Margaret River Perimeter Road Stage 2 (27.16 hectares)
- CPS 818/11 MRWA Reid Highway Malaga Drive Interchange (5.14 hectares)
- CPS 818/11 MRWA Reid Highway duplication Duffy Road to Erindale Road (6.73 hectares)
- CPS 185/5 Water Corporation Baldivis Pressure Main Dixon Road (3.25 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)
 
Lots 218 and 219 are approximately 8.1 and 9 hectares respectively in size and contain a combined total of approximately 5 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.
 
With the funds provided, 3.65 hectares of vegetation across Lots 218 and 219 was purchased. The vegetation present includes suitable western ringtail possum habitat.
