Appendix A. Sin Nombre virus prevalence and total deer mice captured at 17 sites that differed in their degree of disturbance caused by off-road vehicles.

TABLE A1. Sin Nombre virus (SNV) prevalence (Prop.) and total deer mice captured (n) at 17 sites that differed in their degree of disturbance caused by off-road vehicles. The disturbance index is the percentage of shrub cover minus the percentage of bare ground. Sites with positive values of the disturbance index are classified as “High disturbance sites” and those with negative values are classified as “Low disturbance sites”.
