Conclusion
The results of this study show that assessing species richness patterns at multiple grains provides insight into community assembly processes. Variables can exhibit scale-dependent relationships with plant species richness, with some variables having detectable effect on species richness at finer grain sizes, while the influence of others may only become more apparent at coarser grain. Ultimately, using several grains increases understanding of the spatial component of species assemblage patters in response to underlying drivers of species richness.
