Introduction: Biotic soil crust communities contribute valuable ecosystem services and biodiversity in steppe ecosystems. The uncommon crust lichens Acarospora schleicheri, Fuscopannaria cyanolepra, Rhizocarpon diploschistidina, and Texosporium sancti-jacobi are associated with fine-textured soils along rivers of the Columbia Basin. A. schleicheri and R. diploschistidina indicate late-successional habitat and may serve as...
This dataset was digitized from a list of waterways identified by the Oregon Parks and Recreation Department as "state scenic waterways" in accordance with the Scenic Waterways Act.
I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow.
While a great deal of research has illustrated the importance of late-successional forests for...
The purpose of this dissertation was to define macrolichen community gradients in relation to succession, grazing and the environment. First, species scores indicating when macrolichen species appeared following disturbance were derived from the literature. Weighted averaging of these data with a community matrix created a successional score for each sample...
To achieve a goal of “no net loss” of wetland functions as well as acreage, it is important to know which functions wetlands in a specific region or watershed may individually provide, at what level. Although methods exist for assessing functions of Oregon wetlands (ORWAP; Adamus et al. 2009), site...

The Willamette River has gone through extensive changes since Euro American settlement – changes that have reduced channel connectivity, destroyed important habitat for species and vastly undermined floodwater storage capacity. Efforts to preserve portions of the river have a controversial legacy that has left lingering suspicions of government involvement in...
