Riparian vegetation composition and structure associated with channel morphology of headwater meadow streams in the Blue Mountains, northeast Oregon

Creator:: Toledo, Zachary O.
Abstract:: Relationships between the structure and composition of riparian vegetation with channel morphology were examined in three montane meadow streams in the headwaters of the Upper Grande Ronde River and North Fork John Day River in the Blue Mountains, northeast Oregon. Vegetation composition, root biomass, and channel morphology cross-sections were sampled...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

Composition, structure, and biomass of cottonwood-dominated gallery forests along a successional gradient, Willamette River, Oregon

Creator:: Fierke, Melissa K.
Abstract:: Recognizing the importance of native black cottonwood-dominated riparian forests is especially important to preserve, protect, and manage for biodiversity in the Willamette River Valley. Species composition, structure, and biomass along a successional gradient from stand initiation to late succession of black cottonwood (Populus balsamfera L. subsp. trichocarpa (T. & G.)...

Interactive influences of wildfire and nonnative species on plant community succession in Hawaii Volcanoes National Park

Creator:: Ainsworth, Alison
Abstract:: The role of fire as a natural disturbance, its interactions with nonnative species and effects of repeated fires in the Hawaiian Islands have received little investigation. We are unsure of the role fire played in shaping forest structure and composition as well as affecting evolutionary processes of the native biota....

Landscape level patterns in biodiversity : plant species and biomass structure

Creator:: Heider, Christopher
Abstract:: In the tropics, widespread deforestation and conversion of primary forests to agricultural and pasture lands has resulted in losses of composition, structure, and functions of forest landscapes. Deforestation in the tropics is typically preformed via slash-and-burn practices; the byproducts from combustion have been identified as the second-highest form of anthropogenically...

Ecology of woody riparian vegetation in tributaries of the Upper Grande Ronde River basin, Oregon

Creator:: Lytjen, Danna J.
Abstract:: Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde River basin, quantified several physical and biotic influences on woody riparian community composition and structure. The Catherine Creek study examined the association of woody riparian species with elevational and geomorphic gradients. The Meadow Creek study examined the...

Floodplain vegetation following over 80 years of intensive land use and de-watering : Lower Owens River, California

Creator:: Risso, Derek A.
Abstract:: Riparian areas in the arid western United States are critical ecosystems that have been severely degraded by a variety of land and water uses over the last 100 years. In this study, the composition and structure of floodplain vegetation along the Lower Owens River in eastern California was quantitatively described...

Vegetation composition and response to fire of native Willamette Valley wetland prairies

Creator:: Pendergrass, Kathy L. (Connelly)
Abstract:: Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...
