Levi Labbe, 9, watches a sawmill demonstration during his Timber Harvest field trip at Smithfield Plantation nature preserve in Litchfield on Friday. Labbe and five classes of fourth-grade students from Carrie Ricker Elementary School got to see how a timber harvest operates by talking with a sawyer, a logger and a Maine forester. Students visit Smithfield three times each school year, once for Vernal Pool Day, once for Forestry Day and once for the Timber Harvest field trip. Labbe’s classmate Levi Rioux, 9, is at right.
