What is the best way to distribute sample plots over an inventory area? In the absence of any specific prior knowledge about the area, simple random sampling (SRS, section 2.2) is often recommended because of its objectivity and readily available design-based assessment of uncertainty. SRS can easily locate some sample plots very close together, however, and leave large gaps elsewhere. Intuitively, a more representative sample would be obtained by spreading the plots evenly over the inventory area (Figure 10.1).
