The Miracle Resource Eco-Link
Since 1989 Eco-Link Linking Social, Economic, and Ecological Issues The Miracle Resource Volume 14, Number 1 In the children’s book “The Giving Tree” by Shel Silverstein the main character is shown to beneÞ t in several ways from the generosity of one tree. The tree is a source of recreation, commodities, and solace. In this parable of giving, one is impressed by the wealth that a simple tree has to offer people: shade, food, lumber, comfort. And if we look beyond the wealth of a single tree to the benefits that we derive from entire forests one cannot help but be impressed by the bounty unmatched by any other natural resource in the world. That’s why trees are called the miracle resource. The forest is a factory where trees manufacture wood using energy from the sun, water and nutrients from the soil, and carbon dioxide from the atmosphere. In healthy growing forests, trees produce pure oxygen for us to breathe. Forests also provide clean air and water, wildlife habitat, and recreation opportunities to renew our spirits. Forests, trees, and wood have always been essential to civilization. In ancient Mesopotamia (now Iraq), the value of wood was equal to that of precious gems, stones, and metals. In Mycenaean Greece, wood was used to feed the great bronze furnaces that forged Greek culture. Rome’s monetary system was based on silver which required huge quantities of wood to convert ore into metal. For thousands of years, wood has been used for weapons and ships of war. Nations rose and fell based on their use and misuse of the forest resource. -

Latex-Producing Trees and Plants Grow Naturally in Many Regions of the World
A Glimpse into the History of Rubber Latex-producing trees and plants grow naturally in many regions of the world. Yet the making of rubber products got its start among the primitive inhabitants of the Americas long before the first Europeans caught sight of the New World. Moreover, it would be centuries after their "discovery" of America and subsequently becoming aware of rubber's existence before Europeans and others in the so-called "civilized" world awakened to the possibilities offered by such a unique substance. Long before the arrival of Spanish and Portuguese explorers and conquerors, native Americans in warmer regions near the equator collected the sap of latex- producing trees and plants and, after treating it with greasy smoke, fashioned it into useful rubber items. Among the objects they produced were rubber boots, hollow balls and water jars. Finished rubber products of the New World's Indians were observed by Europeans possibly within the first two or three years after their discovery of America and certainly within the first 30 years. Yet most of civilized Europe continued to view rubber as a mere novelty with little commercial importance until well into the 18th century. It's possible that Christopher Columbus himself may have seen rubber being used by the Indian natives of Hispaniola (now Haiti and the Dominican Republic). Columbus, on his second voyage, dated sometime between 1493 and 1496, was rumored to have brought back balls "made from the gum of a tree" that he presented to his financial sponsors, King Ferdinand and Queen Isabella of Spain. The accuracy of that report is in question, however. -

Nanosized PTFE-based core-shell particles can be prepared by emulsifier-free seed emulsion polymerization technique starting from spherical or rod-like PTFE seeds of different size. The shell can be constituted by the relatively high Tg polystyrene and polymethylmethacrylate as well as by low Tg polyacrylic copolymers. Peculiar thermal behavior of the PTFE component is observed due to the high degree of PTFE compartmentalization. -

Balancing Conservation With Utilization: Restoring Populations of Commercially Valuable Medicinal Herbs in Forests and Agroforests.1 Richard A Cech2 ABSTRACT: This paper discusses the medicinal herb industry in relation to conservation of medicinal plants, including an overview of sustainable wildcrafting and sustainable forest agriculture. Goldenseal (Hydrastis canadensis) and Black Cohosh (Cimicifuga racemosa) are given as examples of wild herbs of economic importance which may be readily cultivated. Includes guidelines and techniques for forest farming of hardwood forest dependent species. Introduction plant). I was somewhere in the middle of a long learning.

Chesapeake Forest Restoration Strategy
Eastern Region State and Private Forestry | NA-IN-03-13 | Revised September 2020 Chesapeake Forest Restoration Strategy Chesapeake Forest Restoration Strategy Acknowledgments Acknowledgments Written and edited by Katherine Brownson and Sally Claggett This revision of the Chesapeake Forest Restoration Strategy was a collaborative effort. State forestry agencies in all seven jurisdictions provided the impetus and continued support needed. Our advisory team members played a key role in developing and refining the content (listed on page 6). The following individuals also directly contributed content to the Strategy: Tracey Coulter (Pennsylvania Bureau of Forestry), Lindsey Curtin (U.S. Forest Service), Scott Eggerud (Office of Surface Mining Reclamation and Enforcement), Louis Iverson (U.S. Forest Service), Kate Livengood (The Nature Conservancy), Kate McFarland (USDA National Agroforestry Center), and Matthew Peters (U.S. Forest Service). Our partners at the Chesapeake Bay Program Office helped with essential data and GIS support: Ruth Cassilly (University of Maryland Extension), Peter Claggett (U.S. Geological Survey), Nora Jackson (Chesapeake Research Consortium), and Jeff Sweeney (U.S. Environmental Protection Agency). In addition, multiple individuals gave us their time, professional input, and other information that was instrumental in developing the Strategy: Mary Beth Adams, Carolyn Pike, and Al Steele (U.S. Forest Service); Melissa Deas (D.C. Department of Energy and Environment); Deborah Landau (The Nature Conservancy); and numerous members of the Chesapeake Bay Forestry Workgroup. Finally, Sandra Clark and Deborah Muccio (U.S. Forest Service) provided assistance with editing and design, respectively. We thank all these partners for making this Strategy a reality.
