33rd Dendrochronology Field School (formerly NADEF) 

Mountain Lake Biological Station, VA 

May 17-26, 2024

The 33rd Annual Dendrochronology Field School (DFS; formerly NADEF) will be held at the Mountain Lake Biological Station in Pembroke, VA. DFS returns to the amazing Mountain Lake facility for the first time since 2011, and then in 1993 before that. The surrounding forests of Virginia's Blue Ridge Mountains of the Southern Appalachians offer old growth trees from red spruce to white oak, as well as fire-scarred pines and hardwoods, old cabins for dating, and highly-competitive ecosystems with rich disturbance histories for dendroecology. The field school will run from May 17th through May 26th 2024 and registration fees are $1605 US for students and $1655 US for professionals. Join the Tree-Ring Society and save $55 on registration! Your registration fee includes room and board for the entire workshop. Registration fees are due by April 1, 2024.
