The Carrying Capacity Illusion: Exposing the Systemic Underestimation of Wild Horse Forage on Public Lands
A pervasive narrative in western public land management dictates that the arid and semi-arid rangelands of the United States can support only one wild horse per thousand acres. This figure, which translates to a nationwide Appropriate Management Level (AML) of roughly 27,000 wild horses across 27 million acres serves as the foundational justification for the Bureau of Land Management’s (BLM) aggressive and costly wild horse removal operations. A corollary to this rule is the assumption that these public lands can only produce 12 Animal Unit Months (AUMs) of forage per year per thousand acres.
However, a comprehensive review of the BLM's own allotment data, recent grazing permit renewals, and independent ecological assessments from 2024 through 2026 reveals a starkly different reality. In case after case, the data demonstrates that western public lands produce enough forage to sustain five to seven times as many wild horses as official figures suggest. This report investigates the systemic discrepancy between official carrying capacity claims and actual rangeland productivity, exposing how forage allocations are manipulated to prioritize subsidized livestock grazing at the expense of federally protected wild horse herds and American Taxpayers.
