Use of Sustainably Harvested Wood

The history of lumber harvest in the United States is long and complicated. On one hand, the relentless removal of the aboriginal forests built great cities and industries and made way for the agricultural abundance necessary for building a nation. On the other hand, the de­struction of the aboriginal forests in all regions of the country was for the most part wanton, complete, and without regard for ecological, biological, and human costs.

As a nation we have moved beyond the idea of limitless resources. Wood can be used in an ecologically conscious manner through sustainable harvesting and replanting, along with a commitment to building methods that produce structures with greater longev­ity than the growth periods of the trees from which they are built. A sustainably harvested forest is one in which the forestry practices are continuously monitored and improved to ensure the present and future quality of both the wood resource and the forest itself. This approach includes consideration of the eco­nomic and social impacts on the communities involved and the protection of regional bio­logical diversity.

Sustainably harvested wood can often be obtained for the same price as lumber har­vested by environmentally damaging methods such as clear-cutting. By specifying the use of sustainably harvested woods for a building project, you are helping to raise awareness and increase market demand. Specifying sustain­ably harvested wood can be done by describ­ing the standards the wood must meet in order to be classified as sustainable, or more simply by listing local suppliers of wood that has been reputably certified. In residential construc­tion, where the builder may not have a sizable research and purchasing department, the sec­ond method is more effective.

The Forest Stewardship Council (FSC) is a leading international organization that sets standards for sustainability and accred­its third-party, independent certifiers. In the

US there are currently nine organizations that are FSC accredited. These include the Smart- Wood Certification Program and Scientific Certifications Systems (SCS). The Certified Forest Products Council has now become Metafore. It is a nonprofit organization that provides information on sources for purchas­ing FSC certified wood, with state-by-state listings and more than 4,500 certified loca­tions on its website. It also provides sample specification language tailored for use in the Construction Specifications Institute (CSI) Master Format.

Home Depot, the worlds largest buyer of forestry products, adopted the FSC principles in 2001 and Lowes, the worlds second largest buyer, soon followed suit. Both now offer FSC products in a relatively wide range.
