Abstract A challenging aspect of Habitat Equivalency Analysis (HEA) concerns adequately accounting for the relative value of the injured and restored or replaced resources. This issue is particularly relevant in the case of applying HEA to injured tribal trust (reservation) lands which enjoy special legal and cultural status. NOAA guidelines for HEA application state when choosing a metric to evaluate the quantity and quality of services provided by a unit of habitat, in addition to bio-physical characteristics, trustees should examine landscape, land ownership, and substitute resource characteristics. The analysis presents a theoretical framework and application of augmenting a traditional HEA analysis with discrete choice survey modeling results to ensure all key characteristics of the injured and restored or replaced resources are considered within the equivalency analysis. The example used is for the Spokane Tribe of Indians in Washington State and contamination of their tribal waterway, the Upper Columbia River/Lake Roosevelt. The addition of a discrete choice model of respondent preferences for site characteristics improves the standard HEA analysis by providing an empirical basis for unit equivalencies.

在栖息地等效框架内估算部落资源的补偿率

摘要 栖息地等效性分析 (HEA) 的一个具有挑战性的方面是充分考虑受损和恢复或替换资源的相对价值。这个问题在将 HEA 应用于享有特殊法律和文化地位的受损部落信托（保留）土地的情况下尤其重要。NOAA 的 HEA 应用指南指出，在选择衡量一个栖息地单位提供的服务的数量和质量的指标时，除了生物物理特征外，受托人还应检查景观、土地所有权和替代资源特征。该分析提出了一个理论框架和应用，通过离散选择调查建模结果来增强传统 HEA 分析，以确保在等效分析中考虑受损和恢复或替换资源的所有关键特征。使用的例子是华盛顿州的印第安人斯波坎部落及其部落水道上哥伦比亚河/罗斯福湖的污染。通过为单位等效性提供经验基础，增加了受访者对场地特征偏好的离散选择模型，从而改进了标准 HEA 分析。
