Our team at the Institute for Marine and Antarctic Studies (IMAS) has recently published a new report looking at the health of rocky reefs in the Derwent estuary. We used our new Rapid Visual Assessment methodology that has been developed to identify the early signs of organic enrichment on reef ecosystems.
This project was initiated in 2019 when the Derwent Estuary Program (DEP) engaged our team to undertake a rocky reef monitoring program in the Derwent estuary prior to aquaculture expansion in Storm Bay.
It is important to understand the current health of rocky reefs so that any changes can be monitored over time. This is particularly important in areas of high human activity which can change the natural balance of nutrient availability in coastal water and potentially lead to organic enrichment. These include urban areas, ports and marinas, agriculture, and marine aquaculture.
Key findings from the report show that:
