Statutory process EP Act Environmental Impact Assessment (Part IV)
Approved project area (ha) 985.0

Decision(s):

DECISION 1
Date: 2016-09-23 Ministerial statement: 1036
OFFSET 1
Condition status: Current
Type(s): Land acquisition, Onground management
Rationale:

This offset counterbalances the significant residual impact to the majority of foraging habitat for the Carnaby’s Black Cockatoo and Forest Red-tailed Black Cockatoo and the loss of up to 7.65 ha A Class Nature reserves.

The proponent has acquired a property at Lot M2091 Ioppolo Rd near Chittering and has proposed to cede 673.5 ha of vegetation in excellent condition for vesting as a conservation reserve. The site contains suitable habitat for both species of black cockatoo, including large mature trees with characteristics such as hollows that could support breeding activity, as well as containing additional values. The remainder of the property will be used as an offset for a separate proposal.

The acquisition of this site involves protection of environmental values through improved security of tenure as well as providing for the long term maintenance of values, as the proponent will provide funds for ongoing management of the site.

The remaining residual impacts to black cockatoo foraging habitat is part of a separate Land Acquisition and Rehabilitation Plan (Offset 2).

Security arrangements:

The offset land will be owned by the Crown, vested in the Conservation and Parks Commission as a Conservation Reserve and managed by the Department of Parks and Wildlife for conservation purposes.

Governance arrangements:

The management of the land shall be governed by the requirements set out in the Ioppolo Road Site Land Acquisition and Management Plan. This plan will be published once approved.

Offset location:

Lot M2091 Ioppolo Road, Chittering WA

OFFSET 2
Condition status: Current
Type(s): Land acquisition, Rehabilitation
Rationale:

This offset counterbalances the significant residual impact to the remainder of foraging habitat for Carnaby’s black cockatoo and Forest red-tailed black cockatoo; Yanga vegetation complex, Bush Forever areas and Conservation Category Wetlands.

The Land Acquisition and Rehabilitation Offsets Strategy will aim to protect and/or restore values to a commensurate or greater value than those being impacted and locate the sites as close to the proposal as possible. The proponent is proposing that restoration would form a significant part of this plan and may therefore acquire land that is in a worse condition than the area being impacted, with the aim of restoring values to those commensurate with the impacted areas. A number of potential properties have been identified by the proponent.

Security arrangements:

The proponent is required to commit to a protection mechanism for the sites acquired, either through ceded to the Crown or a Conservation Covenant in perpetuity.

Governance arrangements:

The management of the land shall be governed by the requirements set out in the Land Acquisition and Rehabilitation Offsets Strategy. This Plan will be published once approved.

OFFSET 3
Condition status: Current
Type(s): Onground management
Rationale:

This offset counterbalances the significant residual impact to critical habitat for Caladenia huegelii (Grand spider Orchid).

The proponent will provide funding for the development and implementation of a management plan for potential C. huegelii critical habitat within A Class Nature Reserves 23756, 46919 and 46875 and Bush Forever Site 300. The scope of this plan will be determined in consultation with Parks and Wildlife and other landowners/managers and be in accordance with the Grand Spider Orchid (Caladenia huegelii) Recovery Plan.

The plan will potentially include the following actions:
- weed and dieback mapping and control;
- management of controlled access such as the installation of cable fencing and heavy duty gates; and
- additional surveys to identify and/or confirm critical habitat and the locations and distribution of populations/individuals.

Security arrangements:

Within A Class Nature Reserves and a Bush Forever site

Governance arrangements:

In accordance with the approved Caladenia huegelii Habitat Management Plan. This Plan will be published once approved.
