How many feral horses in the world?

Estimates of the global feral horse population vary widely, but it is believed that there are between 1 to 2 million feral horses worldwide. The largest populations are found in the United States, particularly in the West, where herds roam freely on public lands. Other notable populations exist in Australia, where they are often referred to as "brumbies." Exact numbers can fluctuate due to factors like environmental conditions and management practices.
