Table 6 Yearly paired-sample mean differences and standard deviation of the differences (Sdiff) for vegetation cover, species richness, interpatch length and LFA stability index for five monitoring plots of the Vanguardia site in Santa Cruz. MDC (Minimum detectable change) using a sample of n=10 or 5 monitors to estimate change using Equation 2.
From: The MARAS dataset, vegetation and soil characteristics of dryland rangelands across Patagonia
