So, if an HMA is zeroed out or turned into a non-producing herd for genetic reasons, it's Cothran's fault?

Myth #4: The BLM is managing wild horse herds to extinction.

Fact: This charge is patently false. The current on-the-range population of wild horses and burros (approximately 38,500) is greater than the number found roaming in 1971 (about 25,300). The BLM is seeking to achieve the appropriate management level of 26,600 wild horses and burros on Western public rangelands, or nearly 12,000 fewer than the current West-wide population. The BLM also actively monitors the genetics of each herd by sending genetic samples to Dr. Gus Cothran at Texas A&M University. Dr. Cothran furnishes the BLM a report on every sample with recommendations for specific herds.
