Systematic grid mapping of sagebrush populations (Asteraceae)

Knowledge graph centered on Systematic grid mapping of sagebrush populations (Asteraceae) with 35 nodes and 116 connections. Top connected: elevational gradients, Artemisia, A. tridentata, Artemisia tridentata, climate change effects on species interactions.

Method synopsis

Complete census of sagebrush individuals within systematic 16m × 16m grids divided into 1m² cells, with measurement of plant dimensions for size estimation.

Synthesized from method descriptions across 2 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 — What sexual diversity in the natural world can teach humans about sex, gender, and inclusive biology (2024), BioScience. The protocol was originally introduced by Devising an ageing technique for <i>Artemisia tridentata ssp. vaseyana</i> near Crested Butte, Colorado (2007). Implementations in other papers (listed below) may differ.

1. Establish study grids
   Grids 16 m x 16 m were laid out at each site and marked in 1 m increments, creating 256 grid cells of 1 m² each. The resulting 256 grid cells were marked using colored flags.
   Quantities: 256 grid cells per site, 1 m × 1 m cell size, 16 m × 16 m total grid areaDuration: Not specifiedConditions: At three different elevational sites: upper (3150 m), middle (2970 m), and lower (2770 m) elevations
   Equipment: colored flags, measuring equipment for 1 m increments
2. Map and measure sagebrush
   Each sagebrush within the grid was marked with a flag, arbitrarily placed on the downslope side of the sagebrush stem. Each sagebrush was measured along the longest axis of its foliage and along the widest axis perpendicular to the long axis to give a rough estimate of the size of each plant.
   Quantities: 84 sagebrush at upper site, 29 at middle site, 35 at lower siteDuration: Not specifiedConditions: Field conditions at three study sites
   Equipment: flags, measuring equipment for plant dimensions

Typical Equipment

• colored flags
• measuring equipment

Output Measurements
