Wild (feral) horses roam throughout 15 US states. 13 states are in the western part of the country and the conservation of the horses and burros are mostly controlled by the Bureau of Land Management and the US Forest Service.

Fertility control is the most effective means of wild horse and burro management in the United States. The BLM, USFS, NPS, and USGS all conduct research studies and administor fertility control to specific animals in wild herds.
The use of fertility control is only made possible by the ability to track the bands of animals across vast expanses of land. Camera Traps, mapping, citizen science, and radio controlled collars are technologies that are incorporated into conservation of wild equids in the US to aid in the fertility control process.
In equid conservation, fertility is a major effort. In the United States and Canada, the main conservation efforts are focused on population control and limiting the number of animals on the open range. To be affective with the numerous types of fertility control, agencies rely on satellite radio collars (on previously caught animals), camera traps, mapping, and citizen science to inform them of the number of animals on the range and to allow the policy makes to create plans to implement fertility control on the range.
