Appendix I. A table providing conservation-status statistics for 74 distinct Valley Segment Types (VSTs) in Missouri.

TABLE I1. Conservation status statistics for 74 distinct Valley Segment Types (VST) in Missouri. Table shows the individual elements of each VST, the total length (km) of each VST in the state, and both the total (km) and percentage of total length flowing within GAP management status 1 or 2 lands. The table is sorted by temperature and then stream size, with distinct cell boundaries between these attribute classes to aid in the interpretation of the table.
