Method synopsis

Systematic measurement of plant morphological characteristics (leaf number, leaf area, stalk count, etc.) before plant extraction to develop predictive relationships with total plant biomass. Different characteristics measured based on species morphology.

Synthesized from method descriptions across 8 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 — Convergent ecosystem responses to 23-year ambient and manipulated warming link advancing snowmelt and shrub encroachment to transient and long-term climate–soil carbon feedback (2015), Global Change Biology. The protocol was originally introduced by Plant size and allocation to reproduction for plant demography (2020). Implementations in other papers (listed below) may differ.

1. Measure aboveground biomass
   Aboveground biomass estimated by counting occupied fraction of 275 gridded cells on a 75 x 75 cm quadrat, using regression of coverage vs. measured AGB obtained off-site. For sagebrush, areal coverage measured on foliage at end of growing season (not woody stems). Annual production determined from growing season peak value with correction factor for forb species succession.
   Quantities: 75 x 75 cm quadrats with 275 gridded cells, approximately every ten days during growing seasonDuration: Growing season measurements annually from 1991-2013Conditions: Peak growing season for production estimates, end of growing season for sagebrush coverage
   Equipment: 75 x 75 cm gridded quadrats
