Plant Response to Fire
Round-leaved sundew colonizes recently burned peat surfaces [8,45]. At
the Acadian Forest Experimental Station in New Brunswick, round-leaved
sundew invaded a bog containing short, scattered tamarack after seasonal
burning. It was absent or measured at less than one stem per square
meter prior to burning, but seeds colonized the area in August and
germinated to produce small seedlings. However, the seedlings failed to
establish successfully and subsequently died . Round-leaved sundew
frequency was relatively stable in the five summers following a late
March, 1974, wildfire in a Scotch pine (Pinus sylvestris) woodland in
Scotland; frequency ranged from 35 to 55 percent . The plant may
have occurred in poorly-drained areas that were not completely burned.
Round-leaved sundew was present in a wetland community dominated by tall
shrubs in the Cicero Swamp Wildlife Management Area in New York that had
burned 94 years earlier. Up to 3.3 feet (1 m) of peat had been burned
on some sites, indicating a severe fire. Round-leaved sundew only had a
frequency of 1 percent and cover of 0.1 percent , possibly due to
the cover of tall shrubs.
