^a Contains all terrestrial and emersed aquatic flowering plants identified on the NFWU. Also includes a few miscellaneous plants such as mushrooms and ferns.

^b The relative occurrence of plant species is based on subjective evaluation. The following categories are used to classify relative occurrence:

• Abundant—Easy to find; often a dominant over large areas.
  Common—Easy to find; seldom a dominant over large areas.
  Scattered—Not extremely difficult to find, but more so than ”common”; often thick with patchy distribution or sparse with good distribution; not dominant in the plant community
  Scarce—Difficult to find; often found in relatively small pockets; not well distributed.
  
• Unknown—Plants have been identified on the NFWU, but the authors are unfamiliar with them; most of these plants would probably be categorized as “scarce.”
