WETFEET II: Mangrove and Marsh Growth Under Nitrogen Fertilization in Florida

Experimental data from a fertilization study in northeastern Florida's coastal wetlands, measuring mangrove height, canopy width, and marsh stem density. The dataset was created by Therese Adgie and includes measurements from two sites within the Guana Tolomato Matanzas National Estuarine Research Reserve. Fertilization treatments began in May 2022 at one site and May 2024 at another, with measurements taken roughly every 3-4 months.

Use Cases

• Analyze mangrove growth responses to nitrogen fertilization based on height and canopy width measurements.
• Compare plant community dynamics across marsh-mangrove ecotones based on stem density data.
• Study porewater nutrient concentrations in fertilized plots based on ammonium analysis.
• Model coastal wetland resilience under combined stressors of sea-level rise and nitrogen pollution.

Strengths

• Experimental design includes 2 sites, 2 hydrological locations, and 4 treatments with 5 replicates.
• Measurements are taken repeatedly over time, with some data collected since 2018.
• Data is associated with the established WETFEET research infrastructure.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (346.1 KB), indicating limited scope.
