The objective of this technical report is to provide a synopsis of knowledge regarding the life history, ecology, and management of the American pronghorn antelope in the sagebrush-grassland steppes of North America. Emphasis is given to the management of the habitat. Four basic principles of habitat management are described warranting the attention of wildlife biologists and habitat managers. The relationships of pronghorns to domestic livestock are discussed with suggestions for dual -use management. Under habitat improvements, techniques are provided that are beneficial to antelope regarding how to develop waters, manipulate vegetation, and construct fences. Several case histories are included substantiating that prescribed habitat management practices have resulted in changing low-quality habitat conditions to preferred habitat. The basis for such practices is proper design and implementation of techniques recognizing the pronghorn 's habitat requirements. This has resulted in wider pronghorn distribution and increased populations. Conversely, improperly designed and implemented habitat manipulation practices have limited occupied rangelands.
