The ground-collected data, plus existing literature, were also used to draft the short
descriptions contained in the body of this document. More complete, technical
descriptions of ecological systems, mapping subsystems, and vegetation types were
also drafted, and this 69-page text was provided as a separate document as a delivery
product for this project.

A total of 493 species were found in plots statewide, including 82 that were recorded in
the tree layer, 130 that were recorded in the shrub layer, and 357 that were recorded in
the herbaceous layer (Appendix 1). A total of 76 woody species were recorded in both
the tree and shrub layers.

A total of 85 species were found among the most important species in the tree, shrub,
or herbaceous layers in more than 50 of 3,714 plots (Table 4). Of these, 41 were
herbaceous species, 33 were found in the shrub layer, and 28 were found in the tree
layer. A total of 17 woody species were found in more than 50 plots in both the tree and
shrub layers.
