Bellingham Bay and the Nooksack River Basin 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, cities and towns, and to the east, North Cascades National Park that is protected by the US Wilderness Acts. Using abundant data and model activities from a well-established scientific community, our project seeks to create knowledge, build regional capacity, and forge collaborations toward creation of regional N management solutions that protect or restore ecosystems and human health affected by excess reactive N while maintaining a vibrant agricultural community.
