Abstract
This report presents the outcomes of implementing the Mangrove Monitoring Program (MMP) in 2023-24 across Darwin Harbour and Bynoe Harbour for the Darwin Harbour Integrated Marine Monitoring and Research Program (DHIMMRP). The study area is divided into fourteen zones equivalent to the DHIMMRP water quality reporting zones and their sub-catchments. The remote sensing techniques developed for the MMP (Staben, et al., 2020) were applied from 2016 (the baseline year) through to 2023, using Sentinel-2 satellite imagery, and the results look at 7-year temporal trends in the indicators, extent, and condition to provide updated recommendations for ongoing monitoring. The MMP provides a cost-effective and repeatable means to monitor mangrove health using remote sensing products as indicators (e.g. satellite-derived mangrove extent and canopy ‘greenness’ and images from Unmanned Aerial Vehicles (UAV)). In addition to the remote sensing techniques, this report has implemented the use of innovative high-resolution data captured by UAV technology to identify changes in mangrove health in the years 2018, 2022, and 2023. This brings a new approach to characterising stress levels of Photosynthetic Vegetation – Product (PV) time series and calibrating the Foliage Projective Cover – Woody Index (FPC). The FPC calibration product is a crucial component that permits the removal of the understory vegetation and improves the accuracy of mangrove canopy cover to detect the level of canopy changes caused by stress.,
