Brief description

Currently surveying Logan and Albert Rivers. Due: June 2015 Annual collection of geo-tagged video imagery of shoreline habitats.

Full description

Annual collection of geo-tagged video imagery of shoreline habitats using the Shoreline Video Assessment Method (SVAM) employed by trained community members and organisations. Video imagery is collected using a Sony Handycam from a shallow-draft boat travelling parallel to the shoreline at a distance of ~25m, at a speed between 4 and 6 kts. The video camera is positioned to record directly perpendicular to the direction of travel at all times. Shoreline video imagery is collected with a concurrent time-synchronised 2-second interval GPS track to provide spatial reference to the imagery.

Notes

Features assessed; 1. Mangrove biomass (kg/ha); canopy height, forest structure classification 2. Mangrove condition; presence of canopy dieback, dead trees and canopy density 3. Current shoreline change and mangrove forest process; exposed, stable, expanding 4. High value mangroves at risk of loss; score of mangrove functional capacity 5. Habitat fragmentation; gaps (natural or human) in continuous mangrove stands. continuity score, human modification score 6. Complimentary GIS Assessment; historical shoreline change, mangrove habitat change (1958-2011), Social: Community members provide voice commantary - local issues. And overlay with ecological assessment.
