The main threats it faces are the degradation of suitable terrestrial habitat, pollution and loss of suitable breeding pools, and the introduction of the invasive crayfish Procambarus clarkii and non-native fishes which prey on the tadpoles.
This species was last seen in 1948 and is believed to have gone extinct in the early 1950s, likely as a result of habitat alteration and competition with and predation by introduced crayfish Procambarus clarkii, mosquitofish (Gambusia affinis), black mollies (Poecilia sphenops), and bullfrogs (Rana catesbiana).
