   FIG. C1. Interpolated maps of white-footed mouse track activity. Data were collected monthly by examining track plates placed around individual trees on three oak-forest plots (Green, Henry, and Tea) at the Institute of Ecosystem Studies, Millbrook, New York, 2003–2005. Triangles indicate the locations of individual trees where track activity was measured. Colored surfaces result from point kriging based on exponential variogram models fitted to each data set, with warmer colors indicating areas of higher white-footed mouse activity. Yearly maps are based on data averaged over the three months at each tree.
