Importance to Livestock and Wildlife
Round-leaved sundew is commonly eaten by moose on the Kenai Peninsula of
Alaska in late May and June when in preflowering and early flowering
The wetland habitats that round-leaved sundew grows in are important
breeding and staging areas for migratory waterfowl and are rich in a
variety of wildlife .
Round-leaved sundew is present in wetland communities of western
Massachusetts and New York that are dominated by tall shrubs other than
alders (Alnus spp.). These communities, especially the Cicero Swamp in
western Massachusetts, form the primary habitat for the endangered
eastern massasauga rattlesnake .
Round-leaved sundew may be an important food source for bog-dwelling
ants. Ants are opportunistic predators of insects trapped in the leaves
of round-leaved sundew, scavenging up to two-thirds of the prey caught
by the plant .
