A Pragmatic Approach for Developing Landbase Cumulative Effects Assessments with Aggregated Impacts Crossing Multiple Ecological Values

“…For example, in forested ecosystems, specifying threshold levels for forestrelated indicators (e.g., amounts of habitat and/or late-seral forest, patch sizes of interior forest) are dependent upon the objective of the analysis and the context in which the threshold is defined (Andrén 1994;Dykstra 2004;Price et al 2007;Venier et al 2014). Similarly, interdependencies among stream flow, topography, surficial geology, and climate means there is relatively little guidance in the literature on appropriate ecological thresholds for stream and riparian condition indicators (Gergel et al 2002;Squires and Dubé 2013;Gupta et al 2021). Expert opinion can be and often is used to guide interpretations of impact in the absence of more indicator-specific information (Opon and Henry 2020).…”
