In 2006, the then Department of Conservation and Land Management
Fleet) signed an interagency agreement to implement a carbon sequestration
project on CALM managed lands. The project is in accordance with the
directive of the Western Australian Government to sequester carbon dioxide
to offset the emissions of the Government light vehicle fleet. Revegetation
plantings have been undertaken within the Lake Warden and Lake Bryde
Natural Diversity Recovery Catchments.

Maps showing the plot locations are provided in Appendix 1 and a list of the
ha, with similar soil and landscape positions. Three stand-types have been
planted to reflect minor differences in elevation between plots, however,
approximately 80% of the species are the same across all three plots.
Planting was undertaken in 2006 and 2007 with some in-filling undertaken in

The project site comprises numerous plots within a mosaic of lakes, totaling
just over 80ha. There are a mix of soil types across the site, which are planted
with three stand-types; Salt Tolerant in the low areas, Mixed Heath for the
sandy loam areas, and Sandplain on the white sandy soils on dunes.
Plantings were undertaken in 2006 with in-filling occurring in 2007 and 2008.

The interagency agreement stated that DEC was required to revegetate
Recovery Catchments. As at January 2010, DEC has revegetated and
undertaken follow up in-fill plantings of approximately 132 ha. All planting
areas across both Lake Bryde and Lake Warden were undertaken on
previously agricultural lands that had been cleared prior to 1990.
Documentation in accordance with Part Two, Section 1.3 of the Australian
Accounting has been completed. Each plot has had between 2-4 take-off-
points installed and planting boundaries mapped with GPS (max error +/- 7m).
The digital shape files of the plots at both sites have been forwarded to the
cartographic officer at DEC’s Information Management Branch in preparation
for the production of Deposited Plans. DEC has a process in place to develop
Deposited Plans for Conservation Covenants and this process can be initiated
for the Carbon Right and Carbon Covenant, if required by the Department of
Treasury and Finance.
