Nonfee grazing costs on both federal and privately leased land have been a topic of research since the 1960s. A nonfee cost difference of $1.23 animal unit mo (AUM)⁻¹, later adjusted to $1.35 AUM⁻¹, was found between grazing on federal and privately leased land. This value became the base for the federal land forage value in the current federal grazing fee. In 1992, a task force group was formed to further research the value of federal forage and update the range for the federal grazing fee and recommended keeping the fee between $3 and $5, which would be $6.60 and $11.01 in 2018 US dollars. This study aims to update the 1992 nonfee costs of federal and privately leased grazing. Packets containing information on costs of grazing were gathered from randomly selected sheep and cattle producers in Wyoming, Idaho, and California for the yr 2018. The current study found an observed difference of $3.09 AUM⁻¹ between public and privately leased grazing in the three states but found the overall costs to have no statistically significant difference. This research can be used in the future for observing the nonfee cost changes of federally and privately leased land in the western United States.

自 20 世纪 60 年代以来，联邦和私人租赁土地上的免费放牧成本一直是研究的主题。在联邦和私人租赁土地上放牧之间发现非费用成本差异为 1.23 美元动物单位月 (AUM) ^-1，后来调整为 1.35 美元 AUM ^{-1 。}该值成为当前联邦放牧费中联邦土地牧草价值的基础。1992年，成立了一个工作组，进一步研究联邦牧草的价值，更新联邦放牧费的范围，建议将费用保持在3美元至5美元之间，按2018年美元计算，即为6.60美元至11.01美元。本研究旨在更新 1992 年联邦和私人租赁牧场的免费成本。包含 2018 年放牧成本信息的数据包是从怀俄明州、爱达荷州和加利福尼亚州随机选择的羊和牛生产商收集的。当前的研究发现，这三个州的公共和私人租赁放牧之间观察到的差异为 3.09 美元 AUM ^-1但发现总体成本没有统计上的显着差异。这项研究将来可用于观察美国西部联邦和私人租赁土地的非收费成本变化。
