Forest Disturbance and Succession Across a Naturally Fragmented Landscape

This research examines the spatial and temporal dynamics of disturbance between isolated forest habitat islands (kipuka) surrounded by mid-Holocene age lava flows, and areas of surrounding contiguous forest in central Oregon. Keith Hadley and Karen Arabas (Willamette University) head this research in collaboration of Kelly Pohl (climate reconstruction and dendroecological methods), Evan Larson (fire; Willamette University), Sharon Stanton (mistletoe), and Kate Hrinkevich (edge dynamics). Our goal is to document and model the spread of disturbance across a naturally fragmented landscape and to determine how the propagation of disturbance influences post-disturbance forest succession at the landscape scale.
