This huge repository of wood specimens contains more than 2 million pieces. With this raw material, researchers can pinpoint single-year dates for past events and processes, which is vital to studying climate change and unlocking the pre-industrial history of the United States. Funds will provide storage systems within a climate-controlled environment to address current threats from rodents, insects, floods, and temperature variations.
