40 ISSUE 1 • 2018 • WOOD IN ARCHITECTURE MATERIALS & TECHNOLOGY Easy-to-use online maps to track the sustainability of American hardwood trees, species by species and county by county, are being launched by AHEC. By ZƵƉĞƌƚ KůŝǀĞƌ T hese interactive maps will provide transparent and veriĮed data on the sustainable hardwood resources of the USA, state by state and county by county for traders, speciĮers and consumers. A series of online maps forming a key component of the new americanhardwood.org website and using data from the U.S. Forest Inventory Analysis (FIA) programme gives new insights into the sustainability of American hardwood forest resources. The FIA programme is one of the longest running, most comprehensive and scien Ɵ Įcally rigorous forest inventory programmes in the world. It dates back to 1928 when the McSweeney-McNary Forest Research Act ini Ɵ ated the Įrst forest inventories in the United States. In 1974 the Federal Forest and Rangeland Renewable Resources Planning Act (RPA) required the U.S. Department of Agriculture to prepare Renewable Resources Assessment every 10 years. In 1998 the U.S. Farm Bill enhanced the FIA programme with annual updates at state level based on measurement of a propor Ɵ on of plots, to produce a na Ɵ onal report every Įve years. FIA data derives from a combina Ɵ on of sources. Satellite remote sensing is used to measure area, loca Ɵ on and main forest a Ʃ ributes at increasingly high levels of resolu Ɵ on. More than 125,000 forest sample plots across the USA provide detailed informa Ɵ on on forest type, site a Ʃ ributes, tree species, tree size, and tree health. Ques Ɵ onnaire surveys of landowner plans, values, and inten Ɵ ons are made as well as a survey of wood processing facili Ɵ es to track commercial Ɵ mber produc Ɵ on.
