Since the initial planting of Centennial woods in Union Bay Natural Area in 2007, in celebration of the first 100 years of the College of Forest Resource (now known as the School of Environmental and Forest Sciences), Jon Diemer and his wife Martha have become the weekend warriors. They devote every free Saturday to restoration work at the site. As the current UBNA Ranger, I was able to lend a hand and plant a few hemlocks and shore pines this past Saturday, January 16th, 2016.
