Louisiana Wetland Biomass and Nutrient Content from 2021

March and August 2021 data contain total aboveground biomass, necromass, and carbon, nitrogen, and phosphorus content for samples from herbaceous wetlands in Louisiana's Atchafalaya and Terrebonne basins. Measurements were taken at six sites representing a freshwater-to-saline gradient, with five sites adjacent to the Coastwide Reference Monitoring System. The dataset is hosted by ORNL_CLOUD and appears on multiple government data platforms.

Use Cases

• Quantifying carbon storage potential in coastal wetlands using measured total carbon content in biomass and necromass.
• Analyzing nutrient stoichiometry (C:N:P ratios) across a salinity gradient in herbaceous plant communities.
• Calibrating remote sensing models for aboveground biomass estimation in deltaic wetlands.
• Studying seasonal (spring vs. fall) variation in live biomass and dead plant material (necromass).
• Linking site-specific biomass data to adjacent long-term monitoring stations in the Coastwide Reference Monitoring System.

Strengths

• Data covers two distinct seasonal campaigns (spring and fall 2021) for temporal comparison.
• Samples were collected across a deliberate salinity gradient (freshwater, brackish, saline) at six sites.
• Five of the six sampling sites are co-located with established Coastwide Reference Monitoring System stations, providing context.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date, listing both 2021-08-27 and 2026-03 13.
