USACE ERDC Peer Review C. Klimas January 2008 This review is intended to examine CRAM from the perspective of Corps of Engineers’ regulatory responsibilities, sp...moreecifically with regard to its potential applications in determining project impacts, conducting alternatives analyses, establishing compensatory mitigation requirements, and in monitoring mitigation projects to determine whether they are performing satisfactorily. These considerations are equally important in many planning applications, therefore this review may be of interest to persons involved in ecosystem restoration and similar initiatives that concern evaluation of wetland systems before and after changes to ecosystem processes or structure. The review discusses concerns about the sensitivity of CRAM.
Validation of a Wetland Rapid Assessment Method: Use of EPA's Level 1-2-3 Framework for Method Testing and Refinement Stein E.D. , A.E. Fetscher, R.P. Clark, A. Wiskind, J.L. Grenier, M. Sutula, J.N. Collins, C. Grosso. Wetlands 29(2):648-665. 2009 A case st...moreudy of the validation of the riverine and estuarine modules CRAM. This work evaluated responsiveness of the method to “good” vs. “poor” wetland condition, ability to represent a range of conditions, internal redundancy, alternative combination rules for constituent metrics, and reproducibility of results. The use of existing avian diversity, benthic macroinvertebrate indices, and plant community composition datasets as validation of CRAM results demonstrated. Results indicate that CRAM is an effective tool for assessing general riverine and estuarine wetland condition based on its correspondence with multiple independent assessments of condition. This study demonstrates that, when validated, rapid assessment methods provide a meaningful and reliable tool for assessing wetland condition.
