The condition and extent of coastal wetlands within the CMP study area were assessed. The study also identified management actions to improve the ecological health of these sensitive areas.
Four iconic species (Sea Mullet, Australian Pelican, Tawny Frogmouth and Semaphore Crab) were selected from a number of species identified in the Cooks River Community Values Survey in 2021 (Canterbury Bankstown, 2021) as animals that people associated with a healthier Cooks River. The iconic species occupy different habitats throughout the estuary, and the aim of this assessment was to identify ways to improve ecosystem health by focusing on these species, as their conservation can benefit other species sharing similar habitats or facing similar threats.
- 72 individual sites were surveyed as part of this investigation. The sites included reserves, constructed wetlands and constructed saltmarsh benches or inlets which varied in shape and size.
- For each wetland patch surveyed in the field, a comprehensive native species and weed species lists were collated along with general site descriptions, photographs, details of current management, threats, opportunities and climate change challenges.
- A score was developed for each site determining conservation significance, recovery potential and overall priority for rehabilitation. Patches were then rated as Very Good, Good, Fair, or Poor. A map of the overall patch scores is provided below.
- Generalised management actions were tailored to address specific wetland issues and evaluated for their potential impact and risks to iconic species.
- Bigger picture actions/ projects that require a significant capital investment and take a longer period of time to implement including water quality improvement plans, waterways management plans, WSUD wetlands, and bank modifications for saltmarsh and mangrove migration.
- Smaller picture actions/ projects that can be undertaken with a relatively small budget and/ or can be implemented quite quickly including projects focused on increasing habitat complexity (aquatic and terrestrial), weed control, community education, and mapping updates.
