OUR MEASURED TRAITS
Pool-wise CCI and leaf area
Trait values are pooled measurements collected during the 2024 coastal-meadow field campaign and are study observations, not fixed species constants. Only summaries with at least five measurements are shown.
No validated pool-wise trait summary
This species did not meet the ≥5-measurement rule in the supplied CCI or leaf-area summary tables.

How this taxon enters the analysis
These steps show what this record contributes to the 2024 study. They do not turn the taxon name into a remotely sensed measurement.
- 1 · FIELD EVIDENCE22 of 120 plots
12 occupied plots have a positive numeric cover value available for occupied-plot cover summaries.
- 2 · TRAIT ELIGIBILITYNo eligible CCI or leaf-area summary
Neither trait met the documented minimum of five measurements for this taxon, so it contributes no species median to the CCI or leaf-area community-weighted means.
- 3 · MODEL LINKPlot response, not species detection
Plot-level ecological responses are paired with UAV predictors. A fitted model can estimate variation in those responses across the landscape; this record does not train a classifier for Carex flacca.
Interpretation boundary: UAV or satellite imagery does not uniquely identify Carex flacca in this study. Follow the complete field-to-EO workflow →
