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.

Flux quantification for riverine water-quality constituents has been an active area of research. Statistical approaches are often employed to make estimation for days without observations. One such approach is the Weighted Regressions on Time, Discharge, and Season (WRTDS) method. While WRTDS has been used in many investigations, there is a general lack of effort to identify factors that influence its estimation bias.

This is the first Everglades report card. It is a RECOVER product that provides a transparent, timely, and geographically detailed assessment of health of the Florida Everglades using data from May 1, 2012 – April 30, 2017. The Everglades Report Card, a complement to the 2019 System Status Report, assesses and synthesizes ecological data to evaluate overall ecosystem condition using performance-driven metrics compared against a goal or ecologically-relevant threshold.

As a product of the REstoration COordination and VERification (RECOVER) Monitoring and Assessment Plan (MAP), this report details the evaluation of systemwide performance measures and their targets (or goals) using the ecological tools developed over the past several years under the RECOVER’s MAP program to measure restoration progress.

The relative dominance of controlling factors in saltwater intrusion depends on the time scale in which the variability in characterized. Long-term time series data of salinity and temperature has been collected in the Chester River, Chesapeake Bay, showing considerable variabilities of saltwater intrusion with time scales from days to years.

Water clarity is an important ecosystem indicator of eutrophication in Chesapeake Bay and other coastal and estuarine systems across the globe. Although a variety of measures are available to quantify light availability in water, Secchi disk depths have been the most consistent and frequent measure employed in water monitoring programs.

This newsletter summarizes outputs from the initial stakeholder workshop to develop the Bhitarkanika Conservation Area Report Card. The workshop took place between 6–7 February in Bhubaneswar, Odisha, India. More than 40 diverse stakeholders came together at this workshop to define the scope of the Bhitarkanika Conservation Area Report Card, create a shared vision for the future of Bhitarkanika, and discuss indicators, thresholds, and data sources for the report card.

The American Fisheries Society (AFS) and The Wildlife Society’s (TWS) Climate Change and Wildlife Working Group identified ecosystem transformation as a top priority topic to address the emerging climate change issues in natural resource management. A nominated team of experts participated in a workshop on the topic that will result in two synthesis publications.

Nutrient reduction efforts have been undertaken in recent decades to mitigate the impacts of eutrophication in coastal and estuarine systems worldwide. To track progress in response to one of these efforts we use Generalized Additive Models (GAMs) to evaluate a diverse suite of water quality constituents over a 32-year period in the Chesapeake Bay, an estuary on the east coast of the United States.
