AbstractThis study compared the utility of three sampling methods for ecological monitoring based on: interchangeability of data (rank correlations), precision (coefficient of variation), cost (minutes/transect), and potential of each method to generate multiple indicators. Species richness and foliar cover by species were measured for each method on four transects (70 m) in 15 sites (three in each of five plant communities) in the northern Chihuahuan Desert. Randomized species accumulation curves and rank correlations of the three methods were conducted with these data.
