Systematic relocation and resurvey of 1 m x 1 m permanent vegetation plots established in 1947, with species abundance recorded as individuals per square meter. Historical data from multiple time periods (1947-1954, 1969, 1989-1991) was aggregated with new 2014 data to track vegetation changes over 67 years.
Synthesized from method descriptions across 1 paper using this protocol.
