Fact sheet on nutrient trends in the Chesapeake now available

The US Geological Survey and IAN have collaborated to release a one-page fact sheet, Nutrient Trends and Drives in the Chesapeake Bay. The fact sheet quantifies trends and drivers in nutrient loading throughout the Chesapeake Bay Watershed and provides visualizations. This will help high-level managers and policymakers understand the complex processed that drive water quality, informing efforts to have nutrient reduction practices in place by 2025. You can view the full fact sheet here, or check out our short videos (Part 1, Part 2) that explain the main findings.


UMCES and USGS kick off a new science synthesis project

This project aims to translate and synthesize existing USGS scientific research and knowledge to inform conservation and restoration in the Chesapeake Bay watershed and other critical landscapes. Subject matter experts will convene virtually to develop and draft a newsletter summarizing nutrient trends in the Chesapeake Bay watershed. Participants represent UMCES, USGS, and the U.S. EPA Chesapeake Bay Program.

The Chesapeake Bay ecosystem is a national treasure that provides almost $100 billion annually of goods and services. The Chesapeake Bay Program (CBP), is one of the largest federal-state restoration partnerships in the United States and is underpinned by rigorous science. The U.S. Geological Survey (USGS) has a pivotal role as a science provider for assessing ecosystem condition and response in the Chesapeake watershed. Despite significant CBP accomplishments, the pressures of climate change and competing demands on land use and change require an acceleration of progress towards the 10 goals in the Chesapeake Bay Watershed Agreement. USGS Chesapeake studies are increasing efforts to provide integrated science and are engaging stakeholders to inform the multi-faceted restoration and conservation decisions to improve habitat for fish and waterfowl, and socio-economic benefits to the 18 million people living in the watershed.


Land use and cover has management implications

In partnership with the USGS, the IAN team produced a summary of the Chesapeake Bay Program's new Land Use/Land Cover (LULC) Project. The summary includes:

  • The need to have a 1-m resolution data set
  • The methods for data collection, synthesis, and mapping
  • The major findings of the new data set analysis. The characterization of the types of land use show that turf grass is the largest “crop” in the watershed. The land-change analysis reveals that timber harvest produced the largest land change in the watershed
  • Some management implications for the Chesapeake Watershed Agreement Goals and outcomes, including those for water quality, land conservation and healthy watershed, and vital habitat

You can view the summary on the USGS website. The LULC data sets are also available online, with 2013/2014 and 2017/2018 comparative maps.
