Account snapshot.

About & purpose.

The Wivenhoe Land Restoration Pilot is funded by the Queensland Government. The account is a collaboration of CO2 Australia, together with the Queensland Department of Environment and Science (DES), Seqwater and the World Wildlife Fund (WWF). The restoration project will involve the planting of more than 150,000 trees across seven planting sites adjacent to Lake Wivenhoe in South East Queensland; land owned by Seqwater and historically used for grazing purposes. The planting sites, which were initially identified by WWF, are within an important koala habitat corridor in South East Queensland. At least 90% of the trees planted will be species that provide habitat for the koala. This will increase the amount and quality of habitat for the koala in the corridor and provide connectivity between existing areas of habitat. The restoration project will also reduce the amount of sediment runoff entering Lake Wivenhoe, thereby improving water quality in South East Queensland’s largest water storage.

The goal is to monitor and track improvement in biodiversity co-benefits associated with the restoration through the calculation of Native Vegetation Econd®. Ongoing monitoring of the project will be undertaken to help inform management decisions, including Econd® surveys by CO2 Australia ecologists in accordance with the accredited CO2 Australia Native Vegetation Condition Monitoring Method, monitoring and control of weeds, and the assessment of fire breaks and fuel loads to reduced likelihood of wildfire events impacting on the success of the planting sites and surrounding intact remnant vegetation. DES will also from time to time undertake additional co-benefit activities and monitoring, including fauna surveying, radio-tracking and satellite tracking of koalas, flora surveys, soil assessments and water quality sampling. Further opportunities to improve biodiversity co-benefits of the project will continue to be explored.

Environmental Account summary

Significant outcomes.

CO2 Australia is looking to regenerate seven planting areas surrounding Lake Wivenhoe. Currently, each of the planting areas is cleared of remnant vegetation; being dominated by pasture grasses associated with historical cattle grazing. The baseline Econd reflects this historical use. CO2 Australia’s environmental plantings aim to restore these areas; over the life of the project a substantial increase in the Econd is expected as the area is returned to pre-clearing regional ecosystem vegetation communities.

Disclosures & limitations.

Composition (species richness) - Potential for false negatives in species richness assessments, referring to the potential for missing species (often cryptic) that were actually present but not encountered. The implication is to underrepresent the species richness attributes contributing to the Species Richness (composition) indicator.

Control to minimise identified limitation - The Native Vegetation Method outlines the recommended survey time to maximise opportunities to identify/differentiate flowering plants. Field-based assessments were undertaken during March 2020, consistent with the Native Vegetation Method, with greater than-average rainfall in the preceding two months likely to represent favourable conditions for field-based measurements.

Vegetation configuration - Potential subjectivity afforded by the manual designation of areas as a remnant (intact) vegetation and native regrowth vegetation.

Control to minimise identified limitation - The mapping of vegetation configuration categories (remnant and regrowth vegetation) was undertaken by combining the interrogation of Queensland Government RVMM, aerial imagery and field-based assessment to confirm the composition of vegetated areas within 1 km of each of the Econd sites.

Survival assessments of the planted trees were undertaken during October-November 2022 to calculate the area of environmental planting within the project areas in addition to the extent of impact (if any) of inundation of project areas from the filling of the Wivenhoe Dam that occurred during record flooding events in February/March and May 2022. The results of this field-based assessment identified some areas within the project accounting area that supported reduced survival of planted trees.

No significant event or material change in land use was reported or identified.
