Physiological Variation Of Garry Oak (Quercus Garryana) Seedlings To Drought Stress, Matthew A. Merz
Physiological Variation Of Garry Oak (Quercus Garryana) Seedlings To Drought Stress, Matthew A. Merz
All Master's Theses
The purpose of this study was to determine physiological differences in drought response among Garry oak (Quercus garryana Douglas ex Hook. [Fagaceae]) seedlings that grow in distinct populations in Washington state, in order to aid in restoration efforts by informing growers of the potential differences between the acorn collection sites. Acorns from six Washington populations east of the Cascades, as well as one population from Whidbey Island, were collected and grown in containers under controlled conditions. The plants were assessed with and without moderate and severe drought stress induced by withholding water. The most extreme differences in photosynthetic characteristics …

Applying Wetland Rating Systems To Assess Functions Of Depressional Wetlands Created By A Mass Wasting Feature, Table Mountain, Washington, Thomas S. Wachholder
All Master's Theses
The formation of wetlands in the Swauk Watershed has been primarily controlled by mass wasting events, which includes landslide activity. Landslide activity has been the primary influential process in shaping the landscape where wetland systems have formed on the surface of landslide deposits. The wetland sites used in this study, near the base of Table Mountain, were chosen because they inhabit the same ancient landslide, have the same underlying geology, and vary in aspect and elevation. The elevational gradient of the sites ranges from 1300 – 1600 m and the individual wetlands differ in terms of north- and south-facing aspects. …
