Abstract
In some areas of the Arboretum, the canopy has been transitioning from coniferous Douglas fir (Psuedotsuga menziesii) to deciduous big leaf maple (Acer macrophyllum). Dieback of mature Douglas fir trees may be due to the slow-growing root rot fungus, Coniferiporia weirii, or the story may be more complicated. Other soil characteristics like nutrient availability and soil biota communities may influence the susceptibility of mature Douglas fir to C. weirii. To better understand why this transition is happening, Rebecca Bunn is putting together a research class which will evaluate whether other soil characteristics may be contributing to the dieback of Douglas fir and will create a long-term study and database on the Sehome Arboretum. For my senior project my role was to test, edit, and create methods for the class to use for sampling and lab procedures.
