Habitat destruction or degradation through wetland filling, draining, and dredging for development, agriculture, and recreation
Drawdown of the water table by residential developments and industrial activities
Land use practices that disrupt or alter the flow of surface water into wetlands in which they occur
Timber harvesting effects: increased silt load entering the ponds, invasion of exotic plants because of soil disturbance and increased light availability
Agricultural effects: eutrophication induced by agricultural runoff (fertilizers), herbicides
Habitat damage from all-terrain vehicles; most northeastern bulrush sites dry out partially during droughts, allowing vehicular access to the habitat (U.S. Fish and Wildlife Service)
Because most northeastern bulrush occurrences are very small and isolated, they are particularly vulnerable to loss by stochastic events, such as tree-falls, floods, severe droughts, and insect or disease attack.
Other natural threats include fire, succession, beaver, and long-term disruption of natural water level fluctuations
Another threat inherent in small, isolated populations is inbreeding, with subsequent loss of genetic diversity
