    These suspected threats are overgrazing by stock causing disturbance and loss of species habitat; changed fire regimes and predation by cane toads (Rhinella marinus); although there is uncertainty about the latter (NT LRM; pers. comm.).
    Changed fire regimes in this area since European settlement are considered to be causing more frequent fires which could directly impact on the Rosewood keeled snail as well as changing the vegetation structure and composition of its habitat as demonstrated for other camaenid snails (e.g.
    The Committee considers that the species extent of occurrence and area of occupancy is very restricted; and the geographic distribution is precarious for the survival of the species because its occurrence is limited to one location and decline in quality of habitat through the impacts of cattle access and fire may be projected.
