Our trusty boat and crewECOllaboration have been involved in mapping mangrove communities in the Maroochy River, Mooloolah River and Pumicestone Passage.

Our mangrove monitoring programs are designed to serve as a baseline for future mangrove monitoring on the Sunshine Coast, enabling future estuary health to be monitored effectively and providing a means to compare the health of the  mangroves with nearby estuaries. Additionally, this information is designed to assist natural resource managers identify and target specific issues that threaten mangroves in these areas.
A key outcome from these surveys is a long term visual baseline of mangrove extent, structure and condition along the Maroochy and Mooloolah Rivers and Pumicestone Passage shorelines that will provide a means of assessing future change for years to come.

Shoreline Video Assessment

The video assessment of mangrove structure and condition using georeferenced continuous digital video recording of shoreline video imagery is collected using a Sony Handycam from a shallow boat travelling parallel to the shoreline at a distance of 25m and at a speed between 4-10 knots. Voice recordings of observations on mangrove species, composition, structure, condition and threats are made during the recording.

Summary

Subsequent film runs of areas with an existing baseline assessment will enable a detailed assessment of change to be undertaken. This will provide an annual accurate assessment of any improvements or declines in shoreline mangrove condition leading to better management outcomes.
Additional site-based mangrove monitoring including mangrove carbon storage, interior forest condition and sea level rise monitoring may be included as part of the  mangrove monitoring program in coming years.
