This report contains research results and products compiled in the course of the comprehensive review project Systematic review of aquatic ecological integrity assessments in western North America: Identifying challenges and opportunities for integration into landscape conservation plans. Some of these results have been accepted in a peer-reviewed journal (Section 1), others are in preparation for a peer-review submission (Section II). The two remaining sections (III and IV) may contribute to additional peer reviewed publications in the future, but at this time are summarized solely in this report and as background material for the peer-reviewed articles as well as a web report entitled “Assessment of ecological integrity for fresh waters: a review and guide to assessment frameworks and resources, compiled for the Landscape Conservation Cooperative Network” (Kuehne et al. 2016). Each Section is self-contained, with an Introduction, Methods, Results, and Discussion; figures and tables for each section appear at the end of the section (all figures and tables are hyperlinked to facilitate navigation). References for all sections are compiled into a single bibliography at the close of the report.
