Dendrohydrological Reconstruction Of North Fork Nooksack River August Streamflow From Subannual Mountain Hemlock Ring-Widths, Cascade Mountains, Washington State, Hannah Lagassey

WWU Graduate School Collection

Climate warming is driving changes to snowpack and streamflows in snow and ice-driven systems throughout the world. To better understand present and future conditions, we need to examine conditions prior to the onset of climate warming. Tree ring records are used widely to reconstruct pre-instrumental climate and hydrological records. Some locations are more conducive to this methodology than others, however, and moisture-rich environments such as the west slopes of the Cascade mountains continue to present challenges to effective hydrological record reconstruction. Previous researchers working in this environment have employed several techniques in response to this problem, which require integrated dendrochronological …
