A complete Fire Regime Synthesis for inter-mountain basins semi-desert shrub-steppe communities has not yet been published in the Fire Effects Information System. However, information is available from LANDFIRE succession modeling of inter-mountain basins semi-desert shrub-steppe Biophysical Settings (BpS). Table 1 summarizes LANDFIRE data for inter-mountain basins semi-desert shrub-steppe BpSs. Figure 1 shows where they occur. Appendix A lists the inter-mountain basins semi-desert shrub-steppe BpSs and provides results of LANDFIRE succession modeling and links to descriptions for each BpS.

See Appendix A for details specific to each BpS. | |||||||||
