Message: A tree planted in memory of Roberta is a living tribute that benefits every generation, and is the most fitting memorial gift of all. Your memorial tree planted in a National Forest will be a monument and active part of nature for decades to come. Over the course of 50 years, a single tree can generate much needed oxygen, provide air pollution control, recycle water, and control soil erosion. “A tree that looks at God all day, And lifts her leafy arms to pray”
