Considering the historical disturbance and degraded nature of the project area, the modified hydrology,
and the presence of dense patches of weeds, there is a risk that the population of Cycas megacarpa
within the project area will decline without intervention. The project proposes the implementation of a
Cycas megacarpa Management Plan which will detail methods to translocate individuals impacted by
the project out of the degraded habitat and into an existing population off-site, as well as propagate and
plant additional individuals. The management plan will have a net-positive goal, to not only mitigate the
impact of the project but also avoid and potentially reverse the natural decline of the population. The
Cycas megacarpa Management Plan is provided in Appendix J.
Through the successful implementation of this plan, the project is considered unlikely to significantly
impact the species .

C. megacarpa was confirmed within the project area during field investigations. A population of approximately 46 individuals were confirmed within the project area. All 46 confirmed individuals of C. megacarpa will be cleared by the proposed works. Due to the degraded nature of the project area, natural decline of the population is expected. However, through the implementation of the proposed Cycas megacarpa Management Plan, which will strive towards a net-positive outcome, the size of the population will be maintained or increased by translocating and/or propagating and planting cycads. As such, the Project is considered unlikely to lead to a long-term decrease in the size of a local population. C. megacarpa was confirmed within the project area during field investigations.

However, through the implementation of the proposed Cycas megacarpa Management Plan, which will strive towards a net-positive outcome, the size of the population will be maintained or increased by translocating and/or propagating and planting cycads. Accordingly, the extent of occurence will also be maintained or increased through the implementation of the management plan. As such, the Project is considered unlikely to reduce the area of occupancy of a population. C. megacarpa was confirmed within the project area during field investigations.

Impacted cycads will be translocated/planted into an existing population off site, and therefore no additional populations will be created.
