Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Plant functional trait change across a warming tundra biome (2018), Nature. Implementations in other papers (listed below) may differ.

1. Establish vegetation survey sites
   Compiled vegetation survey data from 117 sites across 38 regions within tundra biome. Sites ranged from 40° to 80° latitude and included both permanent plots and vegetation monitoring locations with repeated surveys between 1989-2015.
