A diagram illustrates the current state of Assateague Island's dunes and grasslands and shows the impacts climate change will likely have on this ecosystem. — Climate Change Effects on the Dunes of Assateague…

A diagram illustrates the current conditions of the forest and shrub ecosystem on Assateague Island and shows the impacts climate change will likely have on native species in this area. — Climate Change Impacts on Assateague's Forest…

A conceptual diagram illustrates the current issues that bay subtidal and mudflat habitats face as well as the problems they are likely to face in the future as climate change impacts this ecosystem. — Effects of Climate Change on the Bay Subtidal and…

A conceptual diagram illustrates the current threats to native salt marsh species as well as the threats these species will face as their habitat is altered by climate change. — Effects of Climate Change on the Salt Marsh…

A conceptual diagram illustrates the current issues that beach intertidal habitats face as well as the problems they are likely to face in the future as climate change impacts this ecosystem. — The effects of climate change on the beach…

The steps in this diagram assist Trust Fund recipients in determining the best experimental design and monitoring method for their water quality monitoring project. — Water Quality Management Decision Tree

Ranking tributaries by water quality, then by diffuse nitrogen sources can help to determine which watersheds are high priority. High priority watersheds are those responsible for proportionally more nutrient and sediment inputs to receiving waters than other watersheds. — Steps to Identifying High Priority Tributaries

Some of the most common threats to the national parks ecosystems include those to quality of air, quality and quantity of available water, and the parks native species. Prescribed fire is used to prevent uncontrolled forest fires and to reduce the growth of nonnative species. — Generic Resources and Threats to the Northern…

While Jewel Cave is currently in pristine condition there are several threats that could potential damage this site. These threats include the pollution of ground water that seeps into the cave at various points and visitor impacts. — Jewel Cave National Monument Threats and Features

The diagram lists potential indicators for the Ohio River Basin that were generated at the workshop. The goals listed in this diagram are representative of the things people value in the Ohio River Basin watershed. — Potential Indicators for the Ohio River Basin

Several connections were made at the Lower Mississippi River Basin workshops. These connections will be used to develop a basin-wide report card for the watershed. — Lower Mississippi Workshop Connections

The Chesapeake Bay watershed received an above average annual amount of precipitation in 2013. This accompanied degrading conditions in some regions of the Chesapeake Bay watershed and improving conditions in others. — Chesapeake Bay Watershed Percipitation Map 2013

Unsustainable fishing and aquaculture practices have put pressure on the Chilika Lake ecosystem. Dead fish thrown back into the water contaminate the lake while shrimp pens trap sediment and kill juvenile fish. — Chilika Lake Fishing and Aquaculture Pressures

Improvements in water quality can be counteracted by changes in nutrient sources and land-use practices. Increased nutrient loads from stormwater and intensified agriculture often overwhelm the positive effects of best management practices. — Counteracting Factors Impacting Best Management…

Emergent wetland species are planted in a buoyant matrix that floats at the water surface. The roots of these plants grow through the matrix and take up the nutrients they need to grow directly from the water, potentially decreasing nutrient concentrations. — Floating Wetlands Structure and Impact

Gutters and downspouts installed onto buildings direct rainwater from roofs to rain gardens. Plants with deep root systems encourage stormwater infiltration and absorbs excess nutrient runoff. — Multiple Benefits of Rain Gardens

Diagram depicting Human-caused and natural vulnerabilities of Chesapeake Bay to climate impacts. — Human-caused and natural vulnerabilities of…

Mnemiopsis leidyi is a species of tentaculate ctenophore originally native to the western Atlantic but is now invasive in the Black, Caspian, North and Baltic Seas — Mnemiopsis leidyi (Comb Jelly)
