Figure 4

Apparent monthly survival of black-tailed prairie dogs (Cynomys ludovicianus) on dusted, vaccine and placebo plots on the Meadow Springs Ranch (MSR) and Soapstone Natural Area (SNA) study blocks is shown. Survival data from the Bulger Grazing Allotment (BGA) study block were insufficient for comparison between treatments. The duration of plague activity (red horizontal bars) is shown. All error bars are 95% confidence intervals. NS = not sampled in 2012. See Tripp et al. (2015) for details of sampling/marking at MSR in 2012.
