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.

Coco Lumber Sawdust
MushroomPart II. Oyster Growers Mushrooms’ Handbook 1 Chapter 5. Substrate 91 Oyster Mushroom Cultivation Part II. Oyster Mushrooms Chapter 5 Substrate COCO LUMBER SAWDUST J. Christopher D. Custodio Bataan State College, the Philippines Oyster Mushrooms (Pleurotus spp.) are saprophytic as they obtain there nutrients by decomposing various agricultural by-products. This mushroom has been cultivated worldwide because of its taste and low maintenance technology. There are different substrates that have already been identified that can be utilized for the cultivation of oyster mushroom. The possible substrates include rice straw, coffee pulps, sawdust, and even paper. Most of these are types of low-value lignocellulosic wastes that are primarily derived from agricultural practices or the agro-industry. (J.A. Buswell et. al., 1996) The bioconversion of these wastes is one reason why the cultivation of edible mushrooms is an appropriate practice for a society that depends on its agriculture. In the early 1990s, ‘coco lumber’ was given a great attention in the province as a substitute for hardwood. Sawmills producing lumber from coconut trees bloomed in reaction to the increasing demand for this low cost constructional material. Though beginners in mushroom cultivation are usually persuaded not to use sawdust from softwoods, sawdust from coco lumber (Fig. 1) is another possible substrate for P. ostreatus and has shown great results. Growers living near a coco lumber sawmill can make use of this waste product in order to start their own cultivation of oyster mushroom species. Figure 1. Coco lumber sawdust Coco Lumber Sawdust as a Substrate of Oyster Mushroom Oyster mushroom is one example of edible mushrooms that can utilize lignocellulosic materials as a substrate.

Designing and Establishing a Fine Hardwood Timber Plantations
DESIGNING AND ESTABLISHING A FINE HARDWOOD TIMBER PLANTATION James R. McKenna and Lenny D. Farlee1 Abstract.—Today, new tools and lessons learned from established plantations of black walnut and other fine hardwoods can provide landowners with guidelines to design and establish successful plantations to produce quality timber for the future. From earlier plantations now maturing, we can recognize design features critical during establishment. Current production practices combined with improved tools, ongoing genetic improvement, and lessons learned from various spacing and species mixes make it possible to establish higher quality timber plantations today than previously possible. We summarize new tools for assessing the suitability of soils to grow good walnut and present plantation design strategies to enhance the quality of walnut mixed with other hardwoods to minimize risk if walnut does not grow well. We also include design details that can enhance the aesthetic quality of the land and expand wildlife habitat. As world population increases and available forest new growers will find the background information, lands diminish, timber plantations hold the promise planning considerations, and descriptions of to produce a greater quantity of wood per acre than techniques needed to establish a successful plantation. natural forests (Sedjo 1999, Sedjo and Botkin 1997).

Environmental Considerations of Treated Wood National Park Service – Pacific West Region
Environmental Considerations of Treated Wood National Park Service – Pacific West Region Overview In support of the mission of the National Park Service, making wise decisions about using wood treatments will help protect the natural areas and biodiversity of our parks, and the health of our employees. Preservative-treated wood’s most important benefit is its resistance to water, fungal, and insect damage. Extending the life of wood products reduces the demands on forests for replacement lumber and reduces maintenance and replacement costs. Historic wooden structures that must be repaired with compatible materials or replaced with in-kind materials make durability even more important. Treated woods are nearly impervious to rot and insects, making them good for outdoor use. Wood treated with chromated copper arsenate (CCA) poses certain environmental and health risks, including the leaching of chemicals such as arsenic and chromium into the environment and workers’ risk of exposure to hazardous chemicals. Disposal of treated wood also proves to be an issue, particularly disposal by incineration. Due to these concerns, manufacturers of treated wood and the EPA reached an agreement to end the sale of CCA-treated wood for most lumber products, effective January 1, 2004. The following offers less-toxic alternatives to CCA, handling and use precautions, and other recommendations when considering using treated wood. Due to the toxicity and potential effects on health and the environment, the Presidio Trust implemented a policy on the use of pressure treated lumber. Standard operating procedure now prohibits the use of CCA, ACZA, CZC, ACC, and Pentachlorophenol. All dimensional lumber is now treated with ACQ as an alternative.

Hardwood Lumber and Veneer Series: Black Waknut
PURDUE EXTENSION Hardwood Lumber and Veneer Series Black Walnut FNR-278-W Daniel L. Cassens, Professor and Extension Wood Products Specialist Department of Forestry and Natural Resources, Purdue University, West Lafayette, IN 47907 American Black Walnut (Juglans nigra L.) is probably the most famous and unique species of all our hardwoods. Large trees, defect free and exceptionally well-formed, were once common. Because of its rich, brown, lustrous heartwood with a grain pattern and intermediate pore size falling somewhere between the grainy hardwoods, such as oak and the uniform textured woods such as maple and yellow-poplar, the wood became prized for furniture, paneling, military and sporting gun stocks, novelties, and many other items. The wood was abundant and had a natural resistance to decay and insects. Therefore, it was also commonly used for construction purposes, such as barn timbers. Even as late as the 1960s the author witnessed the sale and use of walnut 1 x 12s for hayrack boards because it would not rot. By the 1970s, the wood became relatively expensive, forcing the furniture and cabinet industry to promote other species. By the mid-1990s, the trend toward light colored hardwoods also lessened walnut’s popularity. Today, it is preferred in office furniture, architectural millwork, flooring, high-end gun stocks, specialty, and custom items. Some suppliers Chip Morrison feel that it is becoming somewhat more popular Walnut trees again. However, walnut lumber constitutes less than two percent of all hardwood lumber produced. This species prefers deep, rich, moist soils of Black walnut ranges from the east coast to the alluvial origin.
