Ecology of sympatric populations of mule deer and white-tailed deer in a prairie environment ecologyofsympatr1989wood Year: 1989 STUDY AREA Location and Environment The Cherry Creek Study Area (Fig. 1) was located in eastern Montana at 47° north latitude and 106° west longitude, approximately 20 km northwest of Terry, Prairie County, Montana. It encompassed 543 km? and extended a maximum of 40 km east to west and 23 km north to south. Land ownership was 55 Bureau of Land Management (BLM), 39 private, and 6 State arranged in a checkerboard pattern. The area was bisected from southwest to northeast by the drainage divide of the Yellowstone and Missouri rivers. The most prominent geographic feature was Big Sheep Mountain, that rises 90 m above the adjacent divide to an elevation of 1,096 m. The terrain sloped gradually on either side of the divide to the lowest point (771 m) in the southeast corner, an elevational change of 325 m over 29 km (Fig. 1). Drainages were relatively narrow near the divide but gradually widened along their length and developed distinct floodplains toward the perimeter of the area. Fig. 1. The Cherry Creek Study Area showing drainage divide, Big Sheep Mountain, and 50m elevation contours. The climate is semiarid and continental, marked by extreme fluctuations in seasonal and annual temperature and precipitation. Mean annual temperature at the Buffalo Rapids weather station, located approximately 15 km south of the study area, is C. Total annual precipitation averaged cm, over 70 of which falls from May through September. The average frost-free season is about 110 days ( Dep. Commerce, 1958-1987). However, most growth of native herbaceous plants in the northern plains occurs during April-June (Smoliak 1956), and both plant phenology and production vary widely between years in relation to precipitation and temperatures preceding and during the growing season. Variation in precipitation patterns from year to y
