Overstory Structure and Community Characteristics of Oregon Ash (Fraxinus latifolia) Forests of the Willamette Valley, Oregon

Creator:: Prive, Sean
Abstract:: As species of ash trees become increasingly threatened worldwide by exotic pests and pathogens, it is important to develop descriptions of their ecologies that help guide the conservation and restoration of forests in which they are a major component. Oregon ash (Fraxinus latifolia) is a dominant tree species in wetland...

Germination and establishment in Willamette Valley native prairie plants

Creator:: Russell, Michael C.
Abstract:: Native plants provide many ecosystem services while also having great beauty and are a valuable component of the landscape. As use of these plants in habitat restoration, agricultural insectary plantings, and home landscapes increases so does demand for information on the basic biology of a group of species that have...

Butterfly and flower community composition among prairie-oak ecosystem habitats in the Willamette Valley, Oregon

Creator:: Powers, Breanna F.
Abstract:: Prairie-oak ecosystems in the Willamette Valley, Oregon have experienced habitat loss and degradation; most of these ecosystems are fragmented into smaller patches. Prairie-oak butterfly species, in the Willamette Valley, have decreased dramatically due to loss or degradation of habitat. More research is needed on sustaining the populations of butterflies in...

Evaluation of botanical diversity in Oregon vineyards

Creator:: Schonenberger, Patrik M.
Abstract:: Three different ground cover management strategies were compared at the OSU research vineyard near Alpine, Oregon. Botanical diversity was actively increased in two diverse treatments. Another treatment was botanically uniform and contained creeping bentgrass (Agrostis stolonifera). The composition of the vineyard floor vegetation and grapevine performance as affected by the...

Functional groups, traits, and the performance of species in restoration

Creator:: Roberts, Rachael E. (Rachael Elaine)
Abstract:: In ecological restoration, species that are sown to increase the native plant diversity range in establishment ability. Some species readily establish, while others rarely do. This study set out to investigate some of the potential processes influencing species establishment, as well as the traits that are associated with the success...

The effects of site preparation on native forb establishment in a wet prairie, Willamette Valley, Oregon

Creator:: Norman, Katherine N.
Abstract:: Wetlands and wet prairies are economically and environmentally valuable ecosystems, but many have been degraded or converted to other uses. As human understanding of wetlands' value has increased, restoration efforts have grown correspondingly. Restoration attempts use a diversity of methods, which often include seeding with native plant species. This thesis...

Plant community dynamics in remnant and restored Willamette Valley wetland prairies

Creator:: Schwindt, Rachel A.
Abstract:: Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...

Growth and reproduction of annual bluegrass (Poa annua) in response to trinexepacethyl or prohexadione-calcium at multiple rates and application timings

Creator:: Faletti, Matthew T.
Abstract:: Field experiments were conducted in 2002 and 2003 in the Willamette Valley of Oregon to investigate the effects of two plant growth regulators on the growth and reproduction of the weed annual bluegrass. Previous research suggested that the plant growth regulator prohexadione-calcium hastened senescence of annual bluegrass. Another plant growth...
