ESZF Webinar: Adaptation Forestry Practices for Climate Change Mitigation: a Field Study

— filed under:

The seventh in the Eastern Seed Zone Forum's online lecture and discussion series aimed at providing both information about the creation of seed zones in general and a forum in which professionals, experts, and interested parties discuss the possibility of drafting seed zone guidelines for the eastern United States. In this webinar, Dr. Julie Etterson will present the results of the first climate-informed restoration project in the US Great Lakes forests region.

Please join the USDA Forest Service Reforestation, Nurseries, and Genetics Resources' Eastern Seed Zone Forum for its seventh discussion about what it will take to create seed zone guidelines to serve as tools for improved collaborations and partnership in the region. In this webinar, Dr. Julie Etterson will present the results of the first climate-informed restoration project in the US Great Lakes forests region. This area will likely experience some of the most dramatic effects of climate change in the continental U.S.A. Simulation modeling indicates that temperate tree species that currently occur in the region at low abundance levels (e.g., Quercus rubraQ. macrocarpa and Pinus strobus) will be well-adapted to future climate conditions, but also demonstrates that the natural colonization rates of these species cannot keep pace with the rapidly changing climate leaving many suitable niches unrealized. Dr. Julie Etterson and her team tested the efficacy of within-range planting of climate adapted species sampled from more than one seed transfer zone. In 2013 and 2014 they planted a total of 4,400 seedlings in sixteen sites using both local and seed sources from further south or west where climate conditions are warmer and drier. For three years (2014-2016), they assessed survival, growth, and spring and fall phenology. They compared the fit of the data using four models that featured contrasting factors: 1) seed transfer zones, 2) forest types, 3) geographical position, and 4) climate variables.

About the ESZF

The National Forest System needs your help to develop seed zones for the eastern United States! With the input of forestry and natural resource professionals like you, these seed zones have the potential to provide a common frame of reference for nurseries, arboreta, state and federal agencies, and other natural resource organizations to address sustainable forest management and ecosystem restoration challenges across regional and political boundaries.
