Moss regrowth was measured at a winter harvest site in east central Minnesota where little of the underlying, frozen peat was removed. The recovery of an active sphagnum layer after 5 years of regrowth yielded 7.63± 3.74 t/ha. Twenty years would be needed for 90 percent recovery of the 72 t/ha present before harvest. A 20-year harvest cycle would appear to maximize yields.
