Borkh.) increment cores collected from a provenance planting on the Green Mountain National Forest in Vermont. The planting was established in 2009 and is comprised of 13 provenances spanning the historical range of American chestnut. On October 30, 2018 and November 5, 2018, two increment cores were collected from 107 trees exhibiting minimal to no chestnut blight symptoms. This data package includes a separate file for each of the earlywood, latewood, and whole ring measurements as well as files containing provenance information (location and elevation) and diameter at breast height for each tree measured.<br>The purpose of this study was to explore the influence of spring foliar phenology, winter shoot injury, and climate (temperature and moisture availability) on the radial growth of American chestnut sources planted in a range-wide provenance study at the northern edge of its historical range. American chestnut was once a dominant tree species valued for its wood qualities and abundant seed masts. Chestnut blight, caused by the fungal pathogen (Cryophonectria parasitica (Murr.) Barr), was introduced in the United States in the early 1900s and functionally removed American chestnut from the forest landscape. However, because this fungal pathogen does not attack root systems, formation of new shoots via stump sprouting continues long after main stems die thereby maintaining chestnut's genetic footprint. We are working to enhance our understanding of the influence of environmental factors and genetics on American chestnut growth in order to support current and future restoration efforts.<br>The increment cores are currently archived in Room 166 at the Northern Research Station, Burlington, VT.
