Gulf of Carpentaria Mangrove Dieback Vegetation and Elevation Surveys 2017-2019

Eight field transects across four sites in the Gulf of Carpentaria captured vegetation and elevation data from 2017 to 2019. The surveys, conducted by the NESP TWQ 4.13 project at JCU, focused on shoreline fringing stands of Grey Mangrove with matched pairs for 60%-80% and 90%-100% dieback severity. Data includes elevation measures from highest astronomical tide to mean sea level, plus vegetation species, structure, density, and condition observations.

Use Cases

• Modeling the relationship between tidal elevation and mangrove dieback severity based on transect data from HAT to MSL.
• Analyzing changes in vegetation species composition and structure in response to dieback events described in the field surveys.
• Validating and calibrating remote sensing observations of mangrove dieback using ground-truthed field data from matched severity pairs.
• Assessing the impact of the 2015 dieback event on subsequent coastal vegetation changes up to 2019.

Strengths

• Includes matched pairs of transects for two distinct dieback severity levels (60%-80% and 90%-100%), enabling comparative analysis.
• Surveys cover four distinct geographic sites across two Australian states (Queensland and Northern Territory), providing regional coverage.
• Data captures the full elevation range of the tidal wetland, from highest astronomical tide to mean sea level, for ecological context.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the four specific shoreline sites studied.
