This companion document to the 2020 Mississippi River report card contains information about data sources for all indicators, summary of analysis methods, and scoring details for each of the six America’s Watershed Initiative goals, and for two watershed wide indicators. Additional information regarding the goals is included to provide greater detail and discussion than is possible in the report card document.

Watershed report cards are powerful tools to describe ecosystem status, increase public awareness, and inform and influence decision makers to improve the health of a watershed. This is the first Verde River Watershed Report Card. It is the collective effort of dozens of stakeholders throughout the Verde watershed. Indicators in the report card were selected to assess the health of three different values in the Verde watershed: Water, Habitat, and Communities.

This newsletter summarizes outputs from the second stakeholder workshop to develop the Verde River Watershed Report Card. The objectives of the workshop were to: i) develop indicators, ii) discuss scoring approaches, and iii) establish narrative appropriate for the report card. Indicators for the report card center around three main themes: Water, Habitat, and Communities—all necessary components to determine the health of the Verde watershed.

This newsletter summarizes outputs from the initial stakeholder workshop to develop the Verde River Watershed Report Card. The objectives of the workshop were to: i) introduce the project and agree on expected outcomes; ii) begin the process of developing a report card; and, iii) define the geographic scope of the report card, indicators, thresholds, data sources, and communication plan.

The first ever Tennessee River Basin Report card provides a snapshot assessment of ecosystem stressors, condition, and protection in the Tennessee River Basin. This report card was produced in collaboration with the Tennessee River Basin Network, the Appalachian Landscape Conservation Cooperative, and the University of Maryland Center for Environmental Science.

The Tennessee River Basin Report Card was developed as a tool for prioritization and restoration decisions made in the Tennessee River Basin. The report card document is also meant to serve as an outreach tool for use by managers to highlight particular issues of importance when communicating conservation and restoration with the public. This methods document discusses how the report card was developed and how the grades were calculated.

Stream network density exerts a strong influence on ecohydrologic processes in watersheds, yet existing stream maps fail to capture most headwater streams and therefore underestimate stream density. Furthermore, discrepancies between mapped and actual stream length vary between watersheds, confounding efforts to understand the impacts of land use on stream ecosystems.

The degree to which microbial communities adjust their decomposition of soil carbon over time in response to long-term increases in temperature is one of the key uncertainties in our modeling of the responses of terrestrial ecosystems to warming. To better understand changes in temperature sensitivity of soil microbial communities to long-term increases in soil temperature, we incubated 27 soils for one year with both short-term and long-term manipulations of temperature.

Channel heads are the beginning of river networks and thus knowing their location is important in assessing water resources and health threats to fluvial ecosystems. Despite their importance, most channel heads are unmapped. Remote sensing technologies have not yet proven effective under forested canopies, suggesting that predictive models of channel head locations are the best solution to the impracticality of field-mapping the millions of these features that exist in the U.S. alone.

The timing of spring leaf development, trajectories of summer leaf area, and the timing of autumn senescence have profound impacts to the water, carbon, and energy balance of ecosystems, and are likely influenced by global climate change. Limited field-based and remote-sensing observations have suggested complex spatial patterns related to geographic features that influence climate.
