Livestock producers using public lands in the West were once concerned primarily with efficient systems for livestock production. Historically, this concept began in 1934 with the passage of the Taylor Grazing Act. Management activities on public lands continued to focus on sustainable livestock production until the 1970s, when the public began to demand enforcement of the Multiple Use Act and the National Environmental Policy Act. During this time, species listing under the Endangered Species Act became more active. Unfortunately, so many species are listed or are being considered for listing that it becomes impossible to develop biological information on causative factors for listing or recovery plans for each one. Peer-reviewed science that addresses management needs is often unavailable, and articles from the gray literature have been used in management plans for both threatened and endangered species and for public land. Personal biases of both scientists and land managers can influence the development of land management plans, especially in cases in which scientific information is minimal. The Land Grant System is well positioned to develop research applicable for public lands. Animal scientists need to be involved in interdisciplinary teams. Livestock producers need to overcome the stigma that livestock grazing is not a sustainable use. Rangeland in poor condition, whether public or private, should be improved if livestock managers are to change the public perception that grazing degrades rangeland. To accomplish this, education and peer pressure should be used. Another approach needed is activism on the part of producers and animal scientists. The public is demanding a voice in public land management. Working groups seem to be the emerging pathway to cooperatively develop management plans.
在西部使用公共土地的畜牧生产者曾经主要关注畜牧生产的高效系统。从历史上看,这一概念始于1934年《泰勒放牧法案》的通过。直到20世纪70年代,公共土地上的管理活动一直侧重于可持续的畜牧生产,当时公众开始要求执行《多种用途法案》和《国家环境政策法案》。在此期间,根据《濒危物种法案》进行的物种名录登记变得更加活跃。不幸的是,有如此多的物种被列入名录或正在被考虑列入名录,以至于不可能为每个物种的列入名录的致病因素或恢复计划制定生物学信息。解决管理需求的同行评审科学往往无法获得,灰色文献中的文章已被用于受威胁和濒危物种以及公共土地的管理计划。科学家和土地管理者的个人偏见都会影响土地管理计划的制定,尤其是在科学信息极少的情况下。赠地系统很适合开展适用于公共土地的研究。动物科学家需要参与跨学科团队。畜牧生产者需要克服畜牧放牧不是可持续利用方式的污名。如果畜牧管理者要改变公众认为放牧会使牧场退化的观念,无论是公共还是私人的状况不佳的牧场都应该得到改善。要做到这一点,应该利用教育和同伴压力。另一种需要的方法是生产者和动物科学家采取行动。公众要求在公共土地管理中有发言权。工作组似乎是合作制定管理计划的新兴途径。
