The Willamette Valley Seed Increase Program: Developing genetically diverse germplasm using an ecoregion approach

Kimiora Ward, et al.   2008

The goal of the Institute for Applied Ecology’s Willamette Valley Seed Increase Program is to develop a supply of ecologically appropriate, genetically diverse native plant material for restoration of prairie ecosystems in the Willamette Valley. In creating restoration germplasm we seek to maximize genetic diversity while simultaneously protecting genetic integrity of extant native populations. In […]

Seed transfer zones for a native grass Festuca roemeri

Barbara L. Wilson, et al.   2008

A common-garden study of Festuca roemeri (Pavlick) E. B. Alexeev (Poaceae) revealed substantial genetic variation within and among 47 populations from throughout its range in the Pacific Northwest, US, for growth, fitness, phenological, and morphological traits. Using climatic and physiographic variables, genetic patterns over the landscape were examined through principal component and regression analysis. Elevation […]

Reintroduction of rare and endangered plants: common factors, questions and approaches

Edward O. Guerrant Jr., and Thomas N. Kaye   2007

The science of reintroduction for conservation purposes is young, and there is still much to learn about the practice. As a means to achieving biological goals of successfully establishing new populations to enhance a species survival prospects, and project goals, such as learning how to go about establishing new populations, reintroduction projects are best done […]

Effects of controlled-burns on native and non-native vegetation in mid-elevation dry meadows of the Umpqua National Forest

Thomas N. Kaye, et al.   2004

This study investigated the effects of controlled burns on native and non-native vegetation in mid-elevation dry meadows of the Umpqua National Forest. The goals of the study were to determine if fire could release native seed banks and increase vigor of native bunchgrasses and forbs, while reducing populations of invasive plants (in particular the exotic […]

Vital steps toward success of endangered plant reintroductions

Thomas N. Kaye   2008

Reintroduction of endangered plants faces many challenges, but the survival of some species may depend on its success. What measures should practitioners take to ensure a successful project, and how should success be measured? Steps in the reintroduction process include planning and identification of objectives, finding source material, propagation, site selection, site preparation, outplanting, monitoring, […]

Seeds of Success for the Bureau of Land Management, Eugene District

Matt Blakeley-Smith   2010

During 2010 the Institute for Applied Ecology (IAE) worked in collaboration with the Bureau of Land Management (BLM), Eugene District to collect seed under the Seeds of Success program. Seeds of Success (SOS) is a national native seed collection program coordinated by the BLM. The goal of SOS is to provide wild collected seed for […]

Using common garden studies to inform seed transfer zones for Willamette Valley species

Stephanie A. Miller, Matthew L. Carlson, Rob Fiegener, Melanie Gisler, Thomas N. Kaye, Kimiora Ward, Lisa Weiss and Amy Young   2008

The question of what seed is genetically and ecologically appropriate for restoration projects in the Willamette Valley has been hotly debated for the last two decades. The lack of data regarding variability of native Willamette Valley species has hampered seed production and restoration efforts and has caused costly delays – both biological and financial. To […]
