species were common to both plantation types at the young age, whereas the total number of species recorded on Al and A2 was 54.
C values for all vascular plants
known from the study area follow Swink and Wilhelm (1994) and the sample sites fall within the geographic scope of their research.

In this discussion, "endangered" (E) refers to any state-native vascular plant
taxon that, based on scientific research and field work, is believed to be or is in danger of becoming extinct or extirpated from all or a large part of the state in the immediate or foreseeable future if not given some type of protection or critical habitat designation (Arkansas Natural Heritage Commission 1987; Freeman et al 1979).
It was the strangest vascular plant
