The Gulf of Mexico is one of the most diverse and productive ecosystems in the world. Its coral reefs are biological diverse habitats, of high cultural and economic significance. This report card was developed during a workshop held in Merida, Yucatan in November, 2019. It outlines potential indicators of coral reef ecosystem health, perceived conditions of the reefs in the Gulf of Mexico, and next steps for developing a quantitative assessment of Gulf of Mexico coral reef ecosystems.

18 February 2020

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.

Using macroalgal bioindicators to map nutrient plumes from fish farms and other sources at a bay-wide scale (Page 1)

Using macroalgal bioindicators to map nutrient plumes from fish farms and other sources at a bay-wide scale

Human activities can elevate coastal levels of dissolved inorganic nitrogen (DIN). As macroalgae readily absorb and accumulate DIN, the elemental (total N and C:N ratio) composition of their tissues is less affected by temporal fluctuations compared to more direct measures of DIN concentration. Additionally, their isotopic (δ15N) composition can reflect that of the source, which could potentially be used to identify between multiple effluent sources.

Early ecosystem health report cards focused on assessing the health of natural ecosystems, producing a “snapshot” of ecosystem health at one point in time. Ecosystem health report cards are used to guide efforts that improve ecosystem health through natural resources manage- ment and stakeholder engagement. Common themes among Report Cards include water quality and quantity and habitat. These indicators are not strictly environmental concerns, though.

6 November 2019

The Belmont Forum Synthesis Workshop was held virtually, with four project teams from around the globe participating remotely. The process was convened by the Belmont Forum and facilitated by the University of Maryland Center for Environmental Science. It served as the-end term meeting for the Scenarios of Biodiversity and Ecosystem Services I (CRA). Project teams from around the globe participated virtually via online software.

Long-term Annual Aerial Surveys of Submersed Aquatic Vegetation (SAV) Support Science, Management, and Restoration (Page 1)

Long-term Annual Aerial Surveys of Submersed Aquatic Vegetation (SAV) Support Science, Management, and Restoration

Aerial surveys of coastal habitats can uniquely inform the science and management of shallow, coastal zones, and when repeated annually, they reveal changes that are otherwise difficult to assess from ground-based surveys. This paper reviews the utility of a long- term (1984–present) annual aerial monitoring program for submersed aquatic vegetation (SAV) in Chesapeake Bay, its tidal tributaries, and nearby Atlantic coastal bays, USA.

23 September 2019

The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2018 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

In August 2018, the National Climate Adaptation Science Center, with support from the University of Maryland Center for Environmental Science Integration and Application Network, U.S. Forest Service, and the Pacific Islands Climate Adaptation Science Center, held a two-day workshop to synthesize the impacts of drought on various sectors in the USAPI to address this need. Twenty-seven participants from government agencies and universities in the USAPI participated in the meeting.
