摘要

野马和驴子是一种独特的经济资产,享有比大多数其他野生动物更强的联邦保护。目前的人口超过目标四倍之多,管理方面的挑战显而易见。近年来,随着财政成本和机会成本的增加,管理目标与现实之间的不平衡有所加剧。程序性的调整并不能实质性地改变现实。按照目前的轨迹继续下去是不可持续的。经济视角提供了对管理问题的关键洞察,并为持久解决方案的需求提供了清晰的信息。要实现生物和财政上的可持续性,就需要进行全面改革。这包括最初的过度迁移,以减少人口过剩,然后严格遵守目标。这样的计划提供了超过10亿美元的实际贴现财政储蓄。

Wild Horses and Burros in Economic Perspective
Wild horses and burros are a unique economic asset that enjoys federal protections that are stronger than those afforded to most other wildlife. Management challenges are evident in current populations that exceed targets by as much as four times. The imbalance between management targets and reality has grown in recent years, concomitant with mounting fiscal and opportunity costs. Programmatic tweaks have not been able to materially change the reality on the ground. Continuation on the current trajectory is unsustainable. An economic perspective provides key insights into the management problem and provides clarity about the requirements for a durable solution. A comprehensive reform is needed to achieve biological and fiscal sustainability. This includes initial excess removals to reduce overpopulation and then strict adherence to targets. Such a program offers a real present discounted fiscal savings of over $1 billion.

期刊介绍: Rangeland Ecology & Management publishes all topics-including ecology, management, socioeconomic and policy-pertaining to global rangelands. The journal''s mission is to inform academics, ecosystem managers and policy makers of science-based information to promote sound rangeland stewardship. Author submissions are published in five manuscript categories: original research papers, high-profile forum topics, concept syntheses, as well as research and technical notes. Rangelands represent approximately 50% of the Earth''s land area and provision multiple ecosystem services for large human populations. This expansive and diverse land area functions as coupled human-ecological systems. Knowledge of both social and biophysical system components and their interactions represent the foundation for informed rangeland stewardship. Rangeland Ecology & Management uniquely integrates information from multiple system components to address current and pending challenges confronting global rangelands.
