INDEPENDENT BOTANICAL EVIDENCE

General ecology

Centaurea jacea is a robust-rooted perennial herb of dryish meadows, dry riverbank grasslands, glades and verges. It is principally an open-grassland plant in the source account, without a specific coastal association.

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.

FIELD DATA → EARTH OBSERVATION

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. 1 · FIELD EVIDENCE11 of 120 plots

    8 occupied plots have a positive numeric cover value available for occupied-plot cover summaries.

  2. 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. 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 Centaurea jacea.

Interpretation boundary: UAV or satellite imagery does not uniquely identify Centaurea jacea in this study. Follow the complete field-to-EO workflow →
