This chapter demonstrates the process of comparing various multi-scale sampling techniques. This was an actual field study, so there were specific sampling objectives, but the objectives were broad and the approach can be generally applied. The goal was to test nested-plot techniques that could be used by plant ecologists for unbiased estimates of local species richness and mean species cover, analysis of plant diversity spatial patterns at multiple spatial scales, and trend analysis from monitoring a series of strategically-placed, long-term plots. The benefits and limitations of design comparison studies are discussed.

Keywords: nested-plot techniques; nested quadrat design; Whittaker plot design; Modified-Whittaker plot design; multi-scale techniques; species-area curves
