Habitat quality is high at most sites because of their location in protected portions of the Pine Barrens. Alteration of its water regime is a serious threat and therefore N. americanum is vulnerable to beaver activity, cranberry culture, and the damming of streams for recreational lakes. Recovery potential is low if rhizome systems are destroyed because of the long time it takes for young plants to produce rhizomes. Sites should be monitored for population size changes, water level changes, and the number of flowering plants present. Searches for plants at historical sites should continue.
More research is needed on the capacity of vegetative plants to persist in marginal habitats.
The tolerance of fire and logging and the degree to which succession is a threat need evaluation. Protection is needed to maintain the special water requirements necessary for N. americanum to survive. Bassett, G.W. 1912. Trials and Pleasures of the Collector. Bassett, G.W. 1913.
