Sustainable lawn research

June 22, 2012 — At first glance, Tim Schofield’s internship duties don’t appear much different from what any landscape worker does. Every week, June through August, this rising junior at the University of Delaware will weed landscape beds, cut back straggly branches and rake up plant debris on a one-acre yard in Applecross, a neighborhood off Route 100 in Greenville.

But Schofield also will catalog the diversity of beneficial insects, birds and other wildlife on the property, document evidence of soil erosion, and keep precise records of the time it takes to complete his tasks. It’s all part of a UD research project to see if replacing the typical suburban yard of mostly grass with one containing diverse vegetation can help protect the environment and make landscapes more sustainable.

One of the primary goals of the project is to curb water pollution at its source -- preventing pollution in the first place rather than waiting to treat contaminated water after it enters waterways.
