Ripping Improves Tree Survival and Growth on Unused Reclaimed Mined Lands

There is renewed interest in re-establishing trees on 0.6 million ha of mining-disturbed lands in the Appalachian mountains of Eastern United States. Many coal-mined lands reclaimed to meet requirements of US federal law have thick herbaceous vegetation and compacted soils which impede tree establishment. Mitigation practices were applied on three mine sites and evaluated for success in enabling planted trees to become established. Eastern white pine (Pinus strobus), hybrid poplar (Populus deltoids × Populus trichocarpa), and mixed Appalachian hardwoods were established using weed control only and weed control with subsoil ripping. Trees were measured in October of 2008 after 5 years of growth. Subsoil ripping increased mixed hardwood survival from 43 to 71 %, hybrid poplar biomass index from 1.51 to 8.97 Mg ha^?1, and Eastern white pine biomass index from 0.10 to 0.32 Mg ha^?1. When restoring trees to unused mined sites, subsoil ripping can aid survival and growth to an extent that will result in a valuable forest.     

Education for sustainability: Are we flunking the future?

When New Jersey's Office of Sustainability was originally established in 1997, it was at first quizzically referred to as the “Office of What?” Now, good people, high purpose, and new name (Sustainable Business Division of the Commerce Commission) have steadily gained respect as skeptics reflected on what the term sustainability can mean to life on earth as we know it in New Jersey and elsewhere. Current rates of growth in population, industrial production, consumerism, and environmental degradation cannot be supported indefinitely by Earth's finite carrying capacity. New ways of thinking, working, and living will be required to change our course of unsustainable human activity both locally and globally. Such a transformation is achievable only through major changes in education. This article contends that the rate, content, and scope of learning required to take a sustainable path in America are not happening. Some ideas for what needs to be done are suggested.© 1999 John Wiley & Sons, Inc.
