Dulacca Woodland Snail  |  

Adclarkia dulacca

Status: Endangered on the EPBC Act list

Shell medium-sized (diameter 17 mm); pale greenish brown, with a brown band above the periphery of the spirals on the shell. The shell is somewhat flattened, with a very low spire. Spirals rounded, evenly and tightly coiled. The sutures (junctions between the whorls) are weakly present. The tip of the shell bares small rounded knobs. Much of the rest of the shell bears weak growth lines and fine scales on the upper half of the spirals; smooth and glossy beneath. The animal is orange-brown. This species differs from A. cameroni by having a flatter shell, with ’tighter’ coiling.

    Invasion of known potential Buffel grass (Cenchrus ciliaris) has replaced buffel grass native grasses in some areas; and increases in fuel load are correlated with buffel grass invasion (Miller et al.; 2010); leading to more intense fires.
    Increased fire activity in the grassy fringes will damage natural vegetation and facilitate further spread of grass away from the road areas (QMDC 2016).
    Fire High intensity known potential Any fire can cause loss of individuals and negatively impact their habitat.
    The progressive process of habitat decline due to changed fire regimes caused by high biomass grasses (such as buffel grass) is already recognised as a key threat to conservation reserves within the Queensland Murray Darling Basin (QMDC 2016).
    Consider monitoring the impact of feral predator control after any large fire or large rain event.
