| OFFSET 1 |
| Condition status: Current |
| Type(s): Land acquisition |
| Rationale: PROJECT 1 - Bunbury Port Access Road Stage 2 and Bunbury Outer Ring Road Stage 1 (decision date of 14 November 2011).
Note: Clearing for this project was approved 14 November 2011, prior to the approval of an offset proposal. The offset was subsequently approved 20 December 2017 under Clearing Permit CPS 818/12. The details of this offset are published below in line with Clearing Permit CPS 818/12 permit conditions.
The approved offset involves the acquisition of 47.4 hectares of remnant native vegetation for conservation. The vegetation is located immediately adjacent to the proposed clearing area, is predominantly in good to very good (Keighery, 1994) condition, and contains the following environmental values:
- habitat for Carnaby's cockatoo, Baudin's cockatoo and forest red-tailed black cockatoo;
- habitat for western ringtail possum;
- significant remnant vegetation in an extensively cleared area (vegetation mapped as Heddle vegetation complexes Guildford and Southern River);
- a conservation category wetland; and
- an Environmental Protection (Swan Coastal Plain Lakes) Policy 1992 wetland.
The size of the offset required was determined using the Commonwealth Offsets Assessment Guide.
Given the above, the offset is considered relevant to the environmental values being impacted, and proportionate to the significance of the environmental values being impacted. The offset is considered consistent with the principles for the use of environmental offsets outlined in the WA Environmental Offsets Policy September 2011. |
| Security arrangements: Main Roads Western Australia has purchased the offset properties. Conservation will be achieved through converting the properties into Crown Reserves vested with an appropriate government body for conservation (expected to be the Department of Biodiversity, Conservation and Attractions or the Local Government Authority). |

| Condition status: Current |
| Type(s): Rehabilitation |
| Rationale: PROJECT 9 - Pinjarra Williams Road - SLK 81.6 to 91.64 - upgrade (Marradong to Quindanning) (decision date of 30 July 2012).
Note: Clearing for this project was approved 30 July 2012, prior to the approval of an offset proposal. The offset was subsequently approved 12 September 2012.
This offset will result in the rehabilitation of 6.2 hectares of land, 0.6 hectares of which already contains some remnant native vegetation. The rehabilitation will utilise species known to be suitable for black cockatoo foraging and nesting. Given the size of the offset compared to the size of clearing, a net gain in the amount of native vegetation will be achieved.
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. |
| Security arrangements: The offset site occurs in road reserve under the tenure of MRWA. |
| Governance arrangements: |
| Offset location: Portion of the Pinjarra Williams Road reserve at SLK 65 at the intersection of Red Hill Road |
| Approved offset area (ha): 6.2 |

| OFFSET 11 |
| Condition status: Current |
| Type(s): Rehabilitation |
| Rationale: PROJECT 10 - Murdoch Drive South Street intersection upgrade (decision date of 2 August 2012).
Note: Clearing for this project was approved 2 August 2012, prior to the approval of an offset proposal. The offset was subsequently approved 3 July 2014 under Clearing Permit CPS 818/11 and amended 21 May 2015 under Clearing Permit CPS 818/12. The amendment related to delaying the commencement of rehabilitation. Given these matters, the details of this offset are published below in line with Clearing Permit CPS 818/12 permit conditions.
The offset involves the rehabilitation of a 0.5 hectare degraded portion of the adjoining Quenda wetland (conservation category wetland). The rehabilitation will improve the condition of a larger area of the wetland, counterbalancing the loss of wetland vegetation from the project.
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. |

In accordance with the approved offset proposal, the following is a summary of the measurable components of the offset:
Overall objective - revegetate the offset site with local plant species that will provide connectivity between bushland remnants, provide feeding habitat for black cockatoo species and reinstate vegetation communities that have been highly cleared.
Criteria for success - vegetation target density of 70% survival rate based on 1750 stems/ha which is made up of 10% upper storey, 70% middle storey and 20% understorey species and a target species diversity of 12 species per 100m2.
Monitoring - the density and prevalence of weeds, and the density and diversity of native species will be assessed against the criteria for success to determine the need for management and remedial action.
Management/remedial action (to achieve the criteria for success) - infill planting and weed control as determined through monitoring. |
| Timeframe: Criteria for success - to be achieved by autumn 2017
Monitoring - to be undertaken each spring and autumn until 2017
