 The greatest threat to "S. leucophylla", as is the case with most "Sarracenia" species, is loss of its unique wetland habitat to development along the Gulf Coast, as well as forest succession that was historically kept in check by natural wildfires.It is also endangered from being one of the largest and showiest "Sarracenia" species, and is vulnerable to poachers of living plants and to the cut-floral trade for use in flower arrangements.
