Throwback Thursday: The FPL Rotting Pit

Thanks to Grant Kirker for writing this fascinating look back into Forest Products Laboratory (FPL) history and science. Kirker is a Research Forest Products Technologist at FPL in the Durability and Wood Protection Research unit.

Throughout its 110-year history, FPL has participated in groundbreaking wood research both nationally and internationally. The FPL research libraries contain a virtual treasure trove of information pertaining to the wise use of wood and wood-based materials. Historical overviews like this would not be possible without them.

One of the earliest endeavors at the newly established Forest Products Laboratory, then located at 1509 University Avenue in Madison, Wisconsin, was the testing of preservative treated wood for the expanding railroad sector in the US. The swift growth of railways across the country had created a huge demand for suitable hardwoods. But high decline rates due to wood rot fungi was a constant concern leading to an unreasonable amount of wood being used to replace rapidly rotting railroad ties. The dawn of wood preservation research at FPL was aimed at increasing the service life of rail ties to reduce the demand on America‚Äôs forests.
