Biological Report 88(41):1–103), assessment of credits and determination of a compensation ratio that reflects existing and/or potential functional
condition in a mitigation bank has been a formidable task. This study presents a framework for a systematic approach for determination
of credits and debits and subsequently the compensation ratio. A model for riparian systems is developed based on this framework
that evaluates credits and debits for spatial and structural diversity, contiguity of habitats, invasive vegetation, hydrology,
topographic complexity, characteristics of flood-prone areas, and biogeochemical processes. The goal of developing this crediting
and debiting framework is to provide an alternative to the current methods of determining credits and debits in a mitigation
bank and assigning mitigation ratios, such as best professional judgement or use of preset ratios. The purpose of this crediting
and debiting framework is to develop a method that (1) can be tailored to evaluate ecological condition based on the target
resources of a specific mitigation bank, (2) is flexible enough to be used for evaluation of existing or potential ecologic
condition at a mitigation bank, (3) is a structured and systematic way to apply data and professional judgment to the decision-making
process, (4) has an ecologically defensible basis, (5) has ease of use such that the level of expertise and time required
to employ the method is not a deterrent to its application, and (6) provides a semiquantitative measure of the condition of
aquatic resources that can be translated to a mitigation ratio. 相似文献
