On Friday 14 September, the ULRG hosted a successful community engagement event comprising an educational garden tour. By way of introduction, Dr Parker outlined a brief history of the origins of the garden. A walk about followed (led by horticulturist, Miranda Alexander) where the importance of the ULRG providing a corridor for birds, insects and other wildlife was discussed as well as alien invasive species and their negative impacts.

Hands on tips on growing indigenous groundcovers and shrubs were shared and together we examined trees with PSHB and considered the consequences this pest may yet reap. The members engaged actively with questions and discussions and the morning was deemed a success for all as members left empowered to be active stewards of their environment.

During the third quarter we initiated a bank restoration project at the beginning of our boardwalk. This area has always been plagued by an infestation of a highly invasive weed called Cyperus rotundus. It is notoriously difficult to eradicate due to its unique reproductive system. This plant spreads rapidly via an extensive network of rhizomes and tubers. A single plant can produce scores of tubers in one growing season, forming a dense mat that completely smothers the soil preventing the natural regeneration of indigenous seedlings. Besides, this Cyperus rotundus is allelopathic releasing chemicals into the soil which inhibit the germination and growth of surrounding plants giving it a significant competitive edge and further reducing biodiversity.

We cleared the area removing all parts of the weed, lightly tilled the soil and then planted a range of indigenous, resilient and self-sustaining groundcovers and shrubs which are naturally adapted to local conditions. They will provide nectar, pollen and seeds for a host of insects, birds and other fauna. This project is a direct investment in biodiversity and ecological integrity. We will continue to monitor the removal of any regrowth to ensure the success of this intervention.
