Description complète des menacesTexte détaillé évaluation IUCNExpert
In recent years, most of the bogs have been heavily damaged by feral pigs. Circle Bog is fenced, but fence damage sometimes allows pigs to gain access in. Human disturbance in the form of fire has damaged one bog within the last three years. Invasive introduced plants including Juncus planifolius, Xyris camplanata, Schizachyrium condensatum, also pose a threat. The species is dioecious, and lack of pollination is thought to result in poor seed set. Fortini et al. (2013) characterized this taxon as extremely vulnerable to climate change (vulnerability index 0.896).
