The American Wood Protection Association (AWPA) use category system (AWPA 2014) is currently used to set above- and below-ground retentions for all commecial wood preservatives and follows the AWPA hazard map for many of its decision criteria. The AWPA hazard map is a composite based on information from several sources, such as utility pole condition surveys by the Rural Electrification Association and climate zones as described by Scheffer (1971). Decay hazard has been used extensively for approximating likelihood of biodegredation of wood-based products, but there is currently little biological component to these calculations. They are simply measures of the physical environment (mean temperature and rainfall) and do not account for the contributions or biodiversity of micro-organisims in each decay hazard zone. We are using metagenomic analysis to identify micro-organisims present in soil under both pine and hardwood overstory in National Forests to identify fungal species found within each decay hazard zone. Our data would strengthen and expand the existing decay hazard map with detailed biological information.
