Figure 9. Trend in number of coyotes taken within the former coyote-free area shown in Fig. 3.

The primary reason behind this surge in control effort is related to the increasing exposure of additional livestock to coyote predation. This exposure is directly related to the relative degree and geographical distribution of the coyote’s movement into the Edwards Plateau. This can be further illustrated by the graduated average coyote take for every 10 square miles worked within each county (Fig. 10).
