"10 Extinct or Nearly Extinct Amphibians to Know More About." The major threats that this species faces are from habitat alteration and fragmentation due to increased infrastructure and agricultural development in Texas and north-eastern Mexico, as well as from water pollution, herbicides and insecticides.
