INDEPENDENT BOTANICAL EVIDENCE

General ecology

Agrostis stolonifera is a perennial grass that may form mats on sea, lake and river shores, in ditches, spring-fed wet ground and salt-marsh habitats. It is associated with wet and riparian ground but is not confined to the coast.

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.

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 EVIDENCE67 of 120 plots

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

  2. 2 · TRAIT ELIGIBILITYCCI n = 69 · leaf area n = 26

    Both traits passed the documented minimum of five measurements. Their species medians can be weighted by relative cover when constructing plot-level 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 Agrostis stolonifera.

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