Abstract Details

2024, Doctor of Philosophy (PhD), Ohio University, Plant Biology (Arts and Sciences).
This dissertation enhances a forest gap model (ForClim) by incorporating seed production and seedling establishment processes, addressing a critical gap in understanding forest regeneration under climate change. The regeneration of forests in the Pacific Northwest (PNW) is a key driver of biodiversity, shaping species composition and ecosystem structure, and climate change is expected to significantly alter these processes, leading to shifts in both biodiversity and timber productivity. Simulations in this study revealed that seedling survival plays a more critical role than seed production in determining future species composition, particularly as climate variability increases. Resilient species like Pseudotsuga menziesii and Pinus ponderosa may sustain or increase their dominance, while species such as Abies grandis and Tsuga mertensiana face declines due to reduced seedling survival. Additionally, current forest management practices may need adjustment, with "no management" maximizing harvest volume for Coastal Douglas fir, while Mountain Douglas fir may experience reduced yields under future extreme climate scenarios. These findings highlight the importance of integrating regeneration processes into forest models to predict forest biodiversity and timber industry outcomes.
