Rare, Threatened and Endangered Plant Monitoring

The goal of the monitoring plan is to observe the distribution and population trends of rare, threatened and endangered plants occurring within the Priest Rapids Project, to inform the state listing process of status, aid potential conservation efforts, enhance ecological knowledge with respect to listed plants, and observe long-term trends of the species. We will conduct monitoring surveys of the 14 rare, threatened and endangered plant populations known to exist within the project.
