The Environmental Requirements for closure of Ranger uranium mine stipulate that the minesite and associated waterbodies must be rehabilitated to a state which allows them to be incorporated into the surrounding World Heritage, and Ramsar-listed Kakadu National Park. Rehabilitation of ecosystem processes is specifically identified in these requirements. Identification of key ecological processes is an essential aspect of developing Ecological Character Descriptions (ECD) for Ramsar sites. However, the mapping of key processes to the biological and ecological measurements commonly used in monitoring programs is a step often ignored or given little attention. The current ECD for Kakadu identifies only two non-biological critical processes: fluvial hydrology and fire regimes. A number of non-critical supporting processes are further identied with ecosystem processes being listed as a supporting process. However, the ECD does not explicitly link these processes with quantifiable measurements typically applied within Ramsar wetland monitoring programs. As part of an ecological risk assessment being conducted for Ranger, ecological processes are being linked with response variables measured as part of the on-going monitoring program at Ranger. Processes have been developed for multiple spatial and temporal scales to evaluate synergies between measurement variables and ecological processes within aquatic ecosystems. The results indicate the need for processes to be considered within a seasonal context, particularly where seasonal variation is very high, as in the wet/dry tropics.
