This publication combines AHEC’s guide to species and the guide to lumber grades in to a single illustrated and comprehensive guide to sustainable American hardwoods. The front half of the publication gives a full break down of the properties, applications, environmental credentials of the commercially available U.S. hardwood species. The back gives a simplified explanation of the NHLA grading system, which is the national standard for the U.S. hardwood lumber industry and forms the basis for export grading.
