Major Point 1: Characteristics "Kiger Mustangs are most often dun in color, although they are found in other solid colors. Compact and well-muscled in appearance," (summarised well in the lead)
Major Point 2: History "Originally feral horses with specific conformation traits discovered in 1977, the name also applies to their bred-in-captivity progeny. " & "DNA testing has shown that Kiger Mustangs are descended largely from Spanish horses brought to North America in the 17th century, a bloodline thought to have largely disappeared from mustang herds before the Kiger horses were found." (summarised well in the lead)
Major Point 3: BLM management and private ownership "The Bureau of Land Management (BLM) administers two herd management areas for Kiger Mustangs in the Burns District—Kiger and Riddle Mountain, in the Steens Mountain area." (summarised well in the lead)

Heading 2History is not accurate because from Heading 3BLM management and private ownership onwards, the timeline is from 2007 to 2013. Refer this FA - Marwari horse, Heading 2 is History and Heading 3 is 1900s to today which renders clarity to the timeline. Also refer this FA - Andalusian horse, Heading 2 is History and "Heading 3"s are Early development, Dissemination, etc..
In this case, I'd recommend using BLM as Heading 2 instead of History. In the History section, after the statement "In 1971, the Wild and Free-Roaming Horse and Burro Act was passed ...", BLM becomes the focal point.
