在不顾有害环境影响谋求发展的情况下，生物多样性补偿提供了一种维持或提高环境价值的机制。它们力求确保发展对环境造成的不可避免的负面影响与环境收益相平衡，其总目标是实现净中性或积极的结果。一旦作出抵消的决定，就会出现关于如何在实践中这样做的多个问题。一个关键的问题是选址。鉴于在受影响地点附近确定补偿的总体目标，以确保在同一地区产生利益，确定潜在补偿地点（例如，本地、生态区域）的适当空间尺度是什么？我们使用马克思的选址算法来解决概念和方法上的挑战，这些挑战与确定一组潜在的抵消地点和确定适当的空间尺度有关。为了证明这一过程，我们检查了怀俄明州乔纳天然气田开发影响的抵消设计。
Biodiversity offsets provide a mechanism for maintaining or enhancing environmental values in situations where development is sought despite detrimental environmental impacts. They seek to ensure that unavoidable negative environmental impacts of development are balanced by environmental gains, with the overall aim of achieving net neutral or positive outcome. Once the decision has been made to offset, multiple issues arise regarding how to do so in practice. A key concern is site selection. In light of the general aim to locate offsets close to the affected sites to ensure that benefits accrue in the same area, what is the appropriate spatial scale for identifying potential offset sites (e.g., local, ecoregional)? We use the Marxan site-selection algorithm to address conceptual and methodological challenges associated with identifying a set of potential offset sites and determining an appropriate spatial scale for them. To demonstrate this process, we examined the design of offsets for impacts from development on the Jonah natural gas field in Wyoming.
