对于“移动目标”，如迁徙物种或易受环境变化影响的地貌，实施养护尤其困难。涉及静态工具的传统保护策略（例如具有固定空间边界的保护区）可能对管理范围正在变化的物种无效。这一不足急需解决。有人提出了更有活力的养护办法，但大多数仍停留在理论上，因此尚未探讨执行问题和衡量成功的标准。然而，近年来，生物多样性抵消的概念在保护界获得了关注。这种抵消有效地取代了在目前的经济发展项目中“失去的”生物多样性，目的是确保生物多样性总体上“没有净损失”。鉴于其灵活性和独特的无净损失要求，抵消提供了一个平台，以测试动态的新方法来保护。在这里，我们探讨了潜在的补偿，以保护移动目标，使用一个复杂的动态的例子：在乌兹别克斯坦的迁徙赛加羚羊（赛加羚羊）。
Conservation is particularly difficult to implement for "moving targets", such as migratory species or landscapes subject to environmental change. Traditional conservation strategies involving static tools (eg protected areas that have fixed spatial boundaries) may be ineffective for managing species whose ranges are changing. This shortfall needs to be addressed urgently. More dynamic conservation-based approaches have been suggested but remain mostly theoretical, and so implementation issues and measures of success have yet to be explored. In recent years, however, the concept of biodiversity offsets has gained traction in the conservation community. Such offsets effectively replace biodiversity "lost" during current economic development projects, and are intended to ensure "no net loss" of biodiversity overall. Given their flexibility and unique no-net-loss requirement, offsets provide a platform for testing dynamic new approaches to conservation. Here we explore the potential for offsets to conserve moving targets, using a complex dynamic example: the migratory saiga antelope (Saiga tatarica) in Uzbekistan.
