Burleigh County is located in the south-central se c tion of the s tate of North Dakota. It l ie s within the Missouri Coteau Dis tr ict of the Glaciated Missouri S e c t ion , Great Plains Province, Interior Plains Physiographic Division of the United S ta te s . E co lo g ica lly , the county l ie s in the Mixed-gras s Prairie Association of the North American Gra s s lands Biome. The Temperate Deciduous Forest Biome is represented by the gallery forests along the Missouri River.
The purpose of this study was to determine which ant sp e c ie s are found in this county, their relative abundance, distribution, nesting h a b i t s , and habitats .
Specimens were co lle c ted from the ne s ts discovered during e x ten - sive travel and intensive observation over the county. Two hundred and ninety-two co lle c tions of ants were made in 1961 and 1962, and then identified. Maps were prepared showing the location of each n e s t. Distribution was correlated with e co lo g ica l and geological fe a tu r e s .
Ecological observations indicated that the ant sp e c ie s could be grouped into three categor ies based upon adaptation to e co log ica l environments: (1) woodlands; (2) gras s lands ; and (3) both woodlands and g r a s s la n d s .
One sp e c ie s , Formica sp. (morsei? ; identification not confirmed), was recorded for the second time in the United Sta te s and the first time in North Dakota. The co lle c tion of Camponotus caryae discolor is only the second recorded for North Dakota. Five other sp e c ie s colle cted r during this study, Formica cr iniventr is , Formica puberula, Formica dakotensis , Formica fo s sa c ep s , and Camponotus herculeanus , had previously been found rarely in North Dakota.
