Enhancing Seedlings Survival in Harsh Environment: Effects of Drought Preconditioning on Cold Hardiness in Douglas Fir Seedlings.
Speaker(s): Vovener de Verlands Edmond, University of Idaho
Description: This study investigated the effects of drought preconditioning on the cold hardiness of two Douglas-fir genotypes in the Idaho Rocky Mountains. Seedlings subjected to extreme drought for two months and moderate stress for three months exhibited increased cold hardiness. These findings have implications for forest health, regeneration, nursery production.

From Mortality to Complexity: A Shifting Understanding of Eastern Spruce Dwarf Mistletoe in Lowland Black Spruce Forests of Minnesota
Speaker(s): Ella Gray, Oregon State University
Description: This work explores the differences in stand structure and composition between uninfected black spruce forests and areas with high mortality due to eastern spruce dwarf mistletoe, a native, biotic disturbance agent in Minnesota. We found significant differences in stand structure and composition after mortality occurred, including shifts in diameter distributions.

Growth and Yield Model Incorporating Competing Vegetation at Mid-Rotation
Speaker(s): John Young, Weyerhaeuser and Bronson Bullock, University of Georgia
Description: Stand growth and yield models are used to predict the growth of intensively managed pine plantations. Competition limits pine productivity, and models may be adjusted via competition indices. Previously defined indices have been limited in their application. A new growth and yield model is proposed which incorporates improved competition indices.
