 Stem density, also referred to as point-to-plant distance, was the most
important measurement for estimating horizontal complexity. An ANOVA
indicated significant differences in stem density by habitat for seedlings, shrubs,
saplings, herbs, and vines, excluding only trees (p=0.05). Stem density was
highest for saplings and seedlings in the mesic hardwood hammock with open
understory (Suggs and Ashley lakes), and highest for shrubs in the bottomland
swamp. A Kruskal-Wallis test demonstrated significant differences between
habitat types (Zar 1984) for sapling, seedling, and shrub species but not for trees or
herbs; herbs were the only factor excluded from the ANOVA results. After
determining that significant differences were found among these strata, I
conducted a multiple comparisons non-parametric test to indicate in which habitat
point-to-plant distances were significant. This demonstrated that sapling and
