“…We established a landscape development index (LDI) to help select study sites representing a gradient of anthropogenic disturbance. We followed LDI protocols used elsewhere in the U.S. (Brown and Vivas 2005;Wardrop et al 2016). The LDI is provided a coarse rank of potential wetland study sites according to their underlying anthropogenic land use and establishes the nal wetland study sites through an iterative process.…”

There are over 700 aquatic ecological assessment approaches across the globe that meet specific institutional goals. However, in many cases, multiple assessment tools are designed to meet the same management need resulting in a confusing array of overlapping options. Here we look at six riverine wetland assessments currently in use in Montana, USA, and ask which tool: 1) best captures the nuance of condition across a disturbance gradient and 2) has the most utility to meet the largest regulatory need. We used descriptive statistics to compare wetland assessments (n = 16) across a disturbance gradient determined by a landscape development index. We also used factor analysis to determine if each tool’s metrics correspond to its overall results and performed as designed. We interviewed regional wetland managers (n = 56) to determine the extent of their use of each of the six tools and how well they trusted the information the assessment tool provided. We found that the Montana Wetland Assessment Methodology best measured the range of disturbance and had the highest utility to meet Clean Water Act (CWA§ 404) needs. Montana Department of Environmental Quality was best for the CWA§ 303(d) & 305(b) needs. The US Natural Resources Conservation Service’s Riparian Assessment Tool was the third most used by managers but was the tool that had the least ability to distinguish across a disturbance, followed by the US Bureau of Land Management’s Proper Functioning Condition. Many tools had internal mechanics that hindered the tool’s ability to act as it was designed.

“…Our initial ranking of case study wetlands, based on remotely sensed LDI, provides a generalized glimpse into landscape drivers that affect wetland conditions (Wardrop et al 2016). Commonly, site data will reveal subtleties in a condition not captured by this approach.…”
