This chapter provides examples and discusses several single-scale sampling techniques for measuring plant diversity. Common techniques include: searching, where a species list is obtained for a site, natural area, of ecosystem; single-scale plots, where plant species and their foliar cover are commonly recorded; and nested-plot designs, where large plots are used to measure trees, and nested smaller plots are used to measure saplings or herbs and grasses. The benefits of single-scale sampling include simplicity, large sample size, and ease of analysis. The limitations of single-scale sampling also are discussed.
