Healthy Watersheds Integrated Assessments Workshop Synthesis
(PUBLISHED REPORT) [Published : Feb 24, 2012]
The U.S. Environmental Protection Agency, in partnership with others, is embarking on the new Healthy Watersheds Initiative to protect our remaining healthy watersheds, prevent them from becoming impaired, and accelerate our restoration successes. In November 2010, a Healthy Wate...
A Watershed Integrity Definition and Assessment Approach to Support Strategic Management of Watersheds
(JOURNAL) [Published : Oct 23, 2015]
Although defined hydrologically as a drainage basin, watersheds are systems that physically link the individual social and ecological attributes that comprise them. Hence the structure, function, and feedback systems of watersheds are dependent on interactions between these soci...
Building Capacity for Collaborative Decisions, Resilient Ecosystems, and Sustainable Practices: Water, Land, Communtiy and People in Estuarine Watersheds
(PRESENTATION) [Presented : Jul 19, 2009]
Population growth, urban expansion, and the warming climate have and will continue to stress our coastal ecosystems. Decisions on how and when to respond with stewardship, adaptation, and mitigation are made by individuals, municipalities, states, and agencies. These decisions ...
[Published : Dec 31, 2003]
The goal of this study is to advance the understanding of how the effects of climate variability and change on stream ecosystems depend on land-use choices in surrounding areas. Global changes affect aquatic ecosystems through changes in water quality, hydrology, temperature, sea...
Genetic response of a white sucker population to experimental whole lake acidification
(PRESENTATION) [Presented : Aug 12, 2016]
Background/Question/MethodsLake acidification can strongly impact the structure and function of lake ecosystems, causing extirpation of some species while other organisms are able adapt to changing pH. We followed the genetics of a population of white sucker (Catostomus commerso...
[Published : Nov 01, 2005]
Many of the environmental issues which we face today are ecosystem in scope and do not correspond to jurisdictional or administrative boundaries. Adopting an ecosystem approach to environmental resource management and risk assessment requires an understanding of the spatial natu...
(PRESENTATION) [Presented : Jun 17, 2002]
ORD's Regional Vulnerability Assessment (REVA) Program is developing and demonstrating approaches to assess current and future environmental vulnerabilities so that risk management activities can be targeted. The sister program to EMA.P (Environmental Monitoring Assessment Progr...
Strategic Plan for Federal Research and Monitoring of Ocean Acidification
(PUBLISHED REPORT) [Published : Mar 01, 2012]
On July 19, 2010, the President signed an Executive Order establishing the nation’s first comprehensive National Policy for the Stewardship of the Ocean, Our Coasts, and Great Lakes and adopted the Final Recommendations of the Ocean Policy Task Force (OPTF 2010). The Final Recom...
Long-term nutrient addition increases respiration and nitrous oxide emissions in a New England salt marsh
(JOURNAL) [Published : May 01, 2018]
Salt marshes may act either as greenhouse gas (GHG) sources or sinks depending on hydrological conditions, vegetation communities, and nutrient availability. In recent decades, eutrophication has emerged as a major driver of change in salt marsh ecosystems. An ongoing fertilizati...
Scleractinian coral microplastic ingestion: Potential calcification effects, size limits, and retention
(JOURNAL) [Published : Oct 01, 2018]
The impact that microplastics (<5 mm) have on scleractinian coral is largely unknown. This study investigated calcification effects, size limits, and retention times of microbeads and microfibers in two Caribbean species, Montastraea cavernosa and Orbicella faveolata, in...
Tribal Ecosystem Research Program (TERP) Workshop: Proper Functioning Condition (PFC) Assessment for Management and Monitoring
(PUBLISHED REPORT) [Published : Dec 01, 2014]
USEPA is developing alternative approaches to quantify improvements to impaired waterbodies (USEPA 303(d)/TMDL Draft Guidance). Tribal environmental programs are leading the way in the paradigm shift towards sustainability of natural resources. Resources such as wildlife, aquatic...
Vulnerability Assessment and Adaptation Planning for Salt Marsh Management: Chesapeake Bay Program Meeting
(PRESENTATION) [Presented : Jun 30, 2021]
The presentation will cover collaborative work with the Partnership for the Delaware Estuary (SHC 10.5.1) on methods for vulnerability assessment and adaptation design for management of salt marsh ecosystems.
Working with Tribes to Assess, Manage, and Improve Ecosystem Function through EPA’s Science to Achieve Results (STAR) Grants Program and Collaborative Research Projects
(SUMMARY) [Published : Jul 30, 2018]
The summary demonstrates how tribes use traditional knowledge/Traditional Ecological knowledge and technical tools and support from EPA in addressing environmental concerns. We highlighted two projects where EPA worked directly with tribes to conduct Riparian Proper Functioning C...
