Emerald Ash Borer

A Living Laboratory at Dempsey Wetlands: Forest Ecology and Emerald Ash Borer Research with Middle School Students

Issue

 Our Research

Through a collaborative effort with Deborah Bogard, a teacher at Dempsey Middle School, 7th and 8th grade advanced science students established monitoring plots and collected ecological data at the Dempsey Wetlands, a 15 ha school forest including mature forest, old fields, and various successional stages.  The project was motivated by the discovery of emerald ash borer (EAB) (Agrilus planipennis) in an adjacent private woodlot.  Students began in fall 2006 by tagging, identifying, and measuring the diameter of trees in 60 plots on transects through the mature forest and along trails in the early successional areas.  Students used a dichotomous winter key that we developed, which includes only tree species, or species groups, commonly found in the school forest.

Expected Outcomes

An emerald ash borer research curriculum, for educators to use for hands-on EAB research designed for students in grades 6-8. 

Research Results

The Youth Scientist curriculum allows students to learn about the benefits of trees and forests and to experience the scientific process while learning about an invasive pest.
