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. Thorpe Ph.D., Institute for Applied Ecology, Corvallis, Oregon

54 NPSO Bulletin Tygh Valley Milkvetch continued from page 47 and 2007 to determine the current status of the populations and evaluate the accuracy and predictive power of the models. This is significant because with strong models, we can predict whether a population is in danger of extinction and in need of management or whether it is likely to persist with little help. These A. tyghensis populations were modeled using a transition matrix approach. This type of model uses information about the reproduction and likelihood of survival of individuals to model the entire population. Plants are grouped into “stages” based on size, and the model uses probabilities that y e o m K a individuals will transition between T these stages to generate the model. The Tygh Valley is rich with unique habitat that supports many rare and endangered plants. Obviously there is a lot of uncertainty that we must take into account.

Monitoring will continue at these sites next year, and with these three years of data, the models can be ef- fectively evaluated and we will have information about the populations that can guide management decisions. The study on A. tyghensis is an important example of how long-term population monitoring can provide valuable information about the health and viability of rare plant populations and give us the information necessary to move to- ward management action.
