Table 1 Published fire history data for each of the three study areas: Bob Marshall (BM), Selway-Bitter-root (SB), and Frank Church (FC). Estimates of present-day fire rotations are indicated with an asterisk (*). Other estimates of fire rotation, derived from contemporary fire history studies, are considered historical rotations for the purposes of this paper.
