In addition, their house-building activity, underground runs, and surface trails (Figure 59) destroy much more marsh than is directly eaten. For example, in a ID-ha brackish marsh area that contained 24 active and 30 inactive houses in April 19S2, 31 new houses were built and 10 "refurbished" during the next year (Table 23). Sixty percent of the active houses and 57 percent of the inactive ones simply disappeared. When muskrat populations are dense, all this activity can decimate a marsh, creating large "eat-outs" especially in the favored brackish marsh three-corner grass (Sci rpus olneyi) (Figure 60). Subsequently the local population, with no.
