 Multiscale Sampling

This chapter reveals that sampling plant diversity at multiple spatial scales may allow for a deeper understanding of relationships between species distributions and composition shifts relative to changing environmental gradients. Like single-scale techniques, different multi-scale techniques have various strengths and weaknesses, and some may be better suited than others for particular study goals and objectives. No single design will be the “end all, be all” for plant diversity sampling. All designs have advantages and disadvantages that must be carefully evaluated. An experimental approach is almost always warranted. Several examples provide a glimpse of the profound potential of multi-scale sampling for plant diversity.

Keywords: nested quadrat design; Whittaker plot design; multiscale techniques; species-area curves; changing environmental gradients; species distribution
