House Mouse (Mus musoulus) - The only specimen of this species captured on the 

 study area was at the residence of one of the local landowners. This species 

 was probably confined to areas of human habitation, agriculture, and immediately 

 adjacent localities. 



Bobcat (Lynx rufus) - Evidence of this species on the area is from one sighting 

 in the sage-grassland type, tracks in the badlands, and specimens captured by 

 local trappers. All of the bobcat sign and the majority of cats trapped were 

 from the badlands type. Because of the lack of actual sightings and the limited 

 nature of indirect evidence, this species was listed as uncommon on this area. 

 Local landowners stated that the bobcat was previously more common, but high fur 

 prices and intense trapping pressure had dramatically reduced their numbers. 



Raccoon (Procyon lotov) - Evidence of the occurrence of this species on the 

 area was from indirect (tracks) observations, one sighting in the sage- 

 grassland, and landowner contacts. Tracks of this species were found in the 

 creek type and this species was largely confined to these areas. Because only 

 one direct sighting was made and tracks were seldom located, this species was 

 listed as uncommon for the area. This species was much more common on the 

 Yellowstone River bottomland adjacent to the study area. 



Red Fox (Vulpes fulva) - This species was largely confined to the Yellowstone 

 River bottomlands and areas immediately adjacent to them. It was also known to 

 occur in the deciduous coulees on the northern and western fringes of the area, 

 but in lesser numbers. Only one sighting of a red fox was made on the study 

 area. Therefore it was listed as uncommon. Historically, this species probably 

 did not occur on this area as the following statement from the Terry Tribune 

 March 22, 1945 illustrates: "A red fox killed by a cyanide cartridge less than 

 a mile upstream from the Powder River bridge (just south of the present study 

 area) was brought into town by A. C. Drew, predatory animal hunter. These 

 animals are a rarity in this country, several old timers remarking that they had 

 never seen one before." 



Coyote (Canis latrans) - Coyotes were observed all seasons and in all vegetation 

 types of the study area. However, they were most frequently observed in the 

 badland and sage-grassland types. Domestic sheep graze parts of the study area 

 and this usually results in efforts to control coyotes. M44 cyanide guns and 

 aerial gunning were used for control on portions of the area. In spite of 

 control efforts, it was not unusual to see coyotes or indirect evidence (scats, 

 tracks, etc.) of coyotes on the area. 



B adger (Taxidea taxus) - This species was observed on three occasions in, or 

 adjacent to prairie dog towns and once in the grassland type. Other indirect 

 evidence (diggings, tracks, etc.) was noted in several dog towns where no 

 individuals were observed. Infrequent sightings justified listing this species 

 as uncommon for the area. This may be an artifact of their low visibility and 

 the species may be more common than indicated. 



Striped Skunk {Mephitis mephitis) - This species was seldom sighted on this 

 area because of its nocturnal habits. When found, it was usually located in the 

 creek type or areas immediately adjacent to them. Most direct observations of 

 this species were road kills on the fringes of the area.
