Canadian-US Demonstration Project Towards an International Nitrogen Assessment System (PRESENTATION)
Bellingham Bay will provide the test case for an international nitrogen (N) management system for North America. Spanning a portion of the western interface of the U.S. and Canada, the region supports intensive agriculture, freshwater and estuarine fisheries, diverse wildlife, ci...
Ecosystem services impacts associated with environmental reactive nitrogen release in the United States (PRESENTATION)
Nitrogen release to the environment from human activities can have important and costly impacts on human health, recreation, transportation, fisheries, and ecosystem health. Recent efforts to quantify these damage costs have identified annual damages associated with reactive nit...
Economic Tools for Managing Nitrogen in Coastal Watersheds (PUBLISHED REPORT)
Watershed managers are interested in using economics to communicate the value of estuarine resources to the wider community, determine the most cost-effective means to reduce nitrogen pollution, and evaluate the benefits of taking action to improve coastal ecosystems. We spoke to...
Is it working? A look at the changing nutrient practices in the Southern Willamette Valley's Groundwater Management Area (PRESENTATION)
Groundwater nitrate contamination affects thousands of households in the southern Willamette Valley and many more across the Pacific Northwest. The southern Willamette Valley Groundwater Management Area (SWV GWMA) was established in 2004 due to nitrate levels in the groundwater ...
N-Sink: A Tool to Identify Nitrogen Sources and Sinks within aWatershed Framework (COMMUNICATION PRODUCT)
N-Sink is a customized ArcMap© program that provides maps of N sourcesand sinks within a watershed, and estimates the delivery efficiency of N movement from sources to the watershed outlet. The primary objective of N-Sink is to assist land use planners, watershed managers, and la...
How to Calculate Your Institution's Nitrogen Footprint (EXTRAMURAL DOCUMENT)
The Nitrogen Footprint Tool (NFT) allows institutions to estimate and manage their nitrogen footprint, and EPA’s Sustainable and Healthy Communities program is supporting an effort to test and expand this approach at multiple colleges, universities and institutions across t...
Effects of stormwater management and stream restoration on watershed nitrogen retention (JOURNAL)
Restoring urban infrastructure and managing the nitrogen cycle represent emerging challenges for urban water quality. We investigated whether stormwater control measures (SCMs), a form of green infrastructure, integrated into restored and degraded urban stream networks can influ...
