Western Reptiles and Amphibians (Stebbins, 1966), he immediately pointed to 

 the sagebrush lizard. Several visits were made to the general area where he 

 had captured these lizards but none were located. His observations of lizards, 

 other than short-horned lizards (i.e. horny toads), was corroborated by a new 

 arrival to Terry who mentioned he too had seen a small lizard in the badlands. 



Frogs and Toads (Salentia) 



Two species of toads and two species of frogs were found on the area. None of 

 the species found were listed as "special interest or concern" species for 

 Montana. 



Plains Spadefoot Toa d (Saaphiopus hombifrons) - This species was observed at 

 a small pool below a seep in the badlands type. It is probably locally common 

 when conditions for breeding are correct (Black, 1970) . Because of the lack 

 of precipitation on the area during the study, they were never found in great 

 numbers. 



Rocky Mountain Toad (Bufo woodhousei) - This was the most common toad found on 

 the study area. Numerous specimens were collected in all vegetation types. It 

 was generally found around pools of water formed after thunder showers and at 

 moist locations on the area, including pools in creeks and at stock reservoirs. 



Although it was not observed on the study area, it is likely that the great 

 plains toad {Bufo cognatus) occurs here. Specimens of this species were col- 

 lected twenty miles to the west of the present study area (Dood unpublished 

 data) in habitat situations similar to that found on this area (i.e. sage- 

 grassland vegetation type). 



Northern Chorus Frog {Pseudacvts triseriata) - Chorus frogs were common on the 

 area and most notable in the spring when every reservoir and intermittent pond 

 resounded with their voices. Their presence was less noticeable as summer 

 progressed and singing terminated. They were found in every vegetation type in 

 situations where sufficient water existed. 



Leopard Frog (Nana pipiens) - Leopard frogs were observed most often in the 

 creek type in pools with sufficient water to last through the summer and where 

 riparian growth was dense enough to provide concealment. They were also observed 

 around stock reservoirs and were at least locally common on the area where 

 year-round water supplies existed. 



Salamanders {Caudata) 



Tiger Salamander {Amby stoma tigrinwn) - The tiger salamander was the only 

 species in this order captured on the study area. Three specimens were captured 

 in pitfalls set for small mammals in the sage-grassland and one in a pitfall 

 in the grassland coulee. In addition, four dead larvae were found at a stock 

 pond in the sage-grassland that was rapidly disappearing from the effects of 

 the drought. Indications were that this species is uncommon but this was 

 probably due in large part to their secretive nature. It is likely that they 

 were common or even locally abundant at stock ponds, especially during the spring, 



ENDANGERED SPECIES 



Of the five species listed as endangered in Montana (grey wolf, whooping crane, 

 black-footed ferret, peregrine falcon and bald eagle), two are known to occur
