Bulletin of the Native Plant Society of Oregon Dedicated to the enjoyment, conservation and study of Oregon’s native plants and habitat VOLUME 41, NO. 5 MAY 2008 Summer Intern Report Developing Conservation Strategies for the Tygh Valley Milkvetch by Laila Bryant The following article is the second in a series where NPSO/Institute for Applied Ecology (IAE) interns discuss their activities during the 2007 field season. Interns participated in rare plant monitoring, restoration, floristic surveys, and other research projects conducted by IAE staff throughout Oregon during the past summer. In this article, Laila Bryant, a student at Reed College, describes our efforts in collaboration with the Prineville District of the Bureau of Land Management to study population growth and trends in Tygh Valley milkvetch. For more information on internship opportunities, please contact IAE at [email protected], 541-753-3099 or visit www. appliedeco.org. Thanks again to NPSO for contributing to botanical education and work experience. Andrea S.
