Project status Complete
Proponent(s) City of Canning
Project location

ROAD RESERVE CANNING VALE 6155
LOT 600 ON DIAGRAM 93996 CANNING VALE 6155

Project bioregion(s) Swan Coastal Plain
Assessment criteria (f) it is growing in, or in association with, an environment associated with a watercourse or wetland.
Residual impact

Loss of up to 2.1 hectares of native vegetation in completely degraded to very good (Keighery 1994) condition that includes vegetation growing in association with a wetland including 0.3 hectares of vegetation located within the boundaries of a Conservation Category Wetland.
Offset conditions

9. Offsets

(a) Determination of offsets
(i) If part or all of the clearing to be done is or may be at variance with one or more of the clearing principles, then the permit holder must implement an offset in accordance with Conditions 9 (a) and 9 (b) of this Permit with respect to that native vegetation.
(ii) In determining the offset to be implemented with respect to a particular area of native vegetation proposed to be cleared under this Permit, the permit holder must have regard to the offset principles contained in condition 9 (b) of this Permit.
(iii) Once the permit holder has developed an offset proposal, the permit holder must provide that offset proposal to the CEO for the CEO’s approval prior to undertaking any clearing to which the offset relates, and prior to implementing the offset.
(iv) Clearing may not commence until and unless the CEO has approved the offset proposal.
(v) The permit holder shall implement the offset proposal approved under condition 9 (a)(iii).
(vi) Each offset proposal shall include a direct offset, timing for implementation of the offset proposal and may additionally include contributing offsets.

(b) Offset principles
For the purpose of this Part, the offset principles are as follows:
(i) direct offsets should directly counterbalance the loss of the native vegetation;
(ii) contributing offsets should complement and enhance the direct offset;
(iii) offsets are implemented only once all avenues to avoid, minimise, rectify or reduce environmental impacts have been exhausted;
(iv) the environmental values, habitat, species, ecological community, physical area, ecosystem, landscape, and hydrology of the offset should be the same as, or better than, that of the area of native vegetation being offset;
(v) a ratio greater than 1:1 should be applied to the size of the area of native vegetation that is offset to compensate for the risk that the offset may fail;
(vi) offsets must entail a robust and consistent assessment process;
(vii) in determining an appropriate offset, consideration should be given to ecosystem function, rarity and type of ecological community, vegetation condition, habitat quality and area of native vegetation cleared;
(viii) the offset should either result in no net loss of native vegetation, or lead to a net gain in native vegetation and improve the condition of the natural environment;
(ix) offsets must satisfy all statutory requirements;
(x) offsets must be clearly defined, documented and audited;
(xi) offsets must ensure a long-term (10-30 year) benefit; and
(xii) an environmental specialist must be involved in the design, assessment and monitoring of offsets.

Decision(s):

DECISION 1
Date: 2007-08-30 Ministerial statement: None
OFFSET 1
Condition status: Complete
Type(s): Rehabilitation
Rationale:

The offset will result in the rehabilitation and management of 6.2 hectares of native vegetation in completely degraded to excellent (Keighery 1994) condition. Approximately 2.2 hectares of native vegetation in degraded to completely degraded condition will be subject to planting/seeding, whilst rehabilitation of the remaining area will be achieved through assisted natural regeneration (removal of weeds and disturbance factors). The offset site was selected because it is land managed by the City of Canning, is in close proximity to the project area, exhibits similar land form, soil and vegetation to the project area, and contains a Conservation Category Wetland with associated vegetation.

The offset aims to remove and minimise threatening processes such as weeds and inappropriate public use and improve overall condition of vegetation communities.

The offset is considered to be relevant and proportionate to the significance of the environmental value being impacted, mitigating the residual impacts of the project.

Once the permit holder has developed an offset proposal, the permit holder must provide that offset proposal to the CEO for the CEO’s approval.
Timeframe:

Prior to undertaking any clearing to which the offset relates, and prior to implementing the offset. Clearing may not commence until and unless the CEO has approved the offset proposal.
Complete: Yes
CONDITION MILESTONE 2
Milestone:

IMPLEMENTATION MILESTONE 1
Milestone:

Implementation Milestone 1 - relates to Condition Milestone 2

The City of Canning is to implement the rehabilitation requirements outlined in the City of Canning's approved offset proposal (v2 dated 19 May 2008)" for the approved offset location. This document includes, but is not limited to, the following rehabilitation requirements:

Vegetation establishment:
- planting of 2-4 seedlings per square meter in degraded to completely degraded areas using up to 32 different species
- assisted natural regeneration through removal of weeds and disturbance factors

Monitoring:
- photographic monitoring and reporting including evaluation of bushland condition, success of weed control and achievement of completiion criteria

Other:
- consolidation of tracks not required
- rubbish removal
- fencing

Remedial actions (if completion criteria are not met):
- infill planting
- weed control

Completion criteria:
- 20% native vegetation cover in the first year
- 50% native vegetation cover in the second year
- 80% native vegetation cover in the third year which is to be maintained or improved upon thereafter
Timeframe:

Vegetation establishment: annually as required
Monitoring: annually
Remedial actions: as required
Complete: Yes
