Method synopsis

Measurement of plant species-specific cover, identification of focal species, and collection of plant biomass and functional traits including specific leaf area and leaf dry matter content.

Synthesized from method descriptions across 55 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Experimental warming decouples plant-fungal symbiont interactions and leads to a more conservative ecosystem (2026), PNAS. The protocol was originally introduced by On the spatial distribution and abundance of herbaceous plants in aspen and conifer forest understories: a test of neutral/statistical versus niche-based theories? (2008). Implementations in other papers (listed below) may differ.

1. Measure plant species cover and biomass
   After 29 years of experimental manipulation, researchers measured plant species-specific cover and identified nine focal plant species that comprised at least 75% of the total aboveground cover across the experiment. They measured aboveground stem and leaf biomass for specific leaf area and leaf dry matter content.
   Quantities: 9 focal plant species representing 75% of total aboveground coverDuration: After 29 years of treatmentConditions: During growing season
   Equipment: measurement tools for biomass
