Trees affect stormwater

Have you noticed trees in St. Paul parks wearing foil cumberbunds?  

The foil is protecting instrumentation designed to monitor the flow of sap within the trees. That data, along with several other data points about the trees, will help researchers learn more about the role trees play in urban watersheds. (See photos)

Graduate student Xiating Chen, her advisor Professor Xue Feng, their research team, and collaborators from the Department of Forest Resources are looking to identify the benefits and burdens that urban nature, particularly trees, provide within an urban watersheds. The trees being studied as part of this project were chosen for their locations near roads, railroads, or industrial areas, allowing the researchers to compare the impacts of various environments and pollutants.
