Coastal-meadow position
Occurrence uses the 30 sampled plots in each community. Community boundaries are not rigid; these are study observations, not a complete Estonian distribution. Study data and methods →
Juncus gerardi is a low perennial rush associated with coastal meadows and salt marshes. FinBIF also records roadside and railway habitats in northern Finland, showing that its occurrence is not universally confined to coastal plots.

Recorded in 52 of 120 sampled plots.
FINBIF TAXONOMY
OUR MEASURED TRAITS
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.
Range 0.8–1.8 · average 1.08 · n = 124
Range 0.091–1.351 · average 0.53 · n = 58

FIELD DATA → EARTH OBSERVATION
These steps show what this record contributes to the 2024 study. They do not turn the taxon name into a remotely sensed measurement.
51 occupied plots have a positive numeric cover value available for occupied-plot cover summaries.
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.
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 Juncus gerardi.
Interpretation boundary: UAV or satellite imagery does not uniquely identify Juncus gerardi in this study. Follow the complete field-to-EO workflow →
