Error introduced by different observers identifying species can be difficult to measure. Never-the-less, doing so can provide insight into data trends over time and serve as a tool to improve team performance. The process of measuring the rate of agreement among observers improves quality in the field and in post-collection processing and reporting opportunities. Measuring error rates is intended to evaluate team performance (sampling error), not individuals. The information is intended to provide transparent information about error rates used for continuous improvement rather than simply evaluation. The double sampling procedure described here used to measure this error can also help observers in the field to strive for accuracy. Goals of this procedure are based on three assumptions. 1. We assume that two botanists work together to complete observations at each monitoring site. Each botanist samples one of the two transects. 2. Botanists work collaboratively for the first site at a new park or plant community. Because of this effort to calibrate and establish basic flora knowledge, the first site at a park or plant community should not be included in the double sampling effort. 3. Double sampling should not influence the way plots are sampled in terms of normal levels of collaboration.
