Figure 2. Texas ecological regions (F. W. Gould, Texas Plants, 1969 revised).

In 1950, there were 33 counties covering nearly 24 million acres which were considered to be coyote free (Fig. 3). This area remained virtually void of coyotes for several decades until their encroachment began in the 1960s. This process has been described by several authors (Caroline 1973, Shelton and Klindt 1974, Hawthorne 1980, Nunley 1985). The purpose of this paper is to review and update the progress of the re-establishment of coyotes into the Edwards Plateau of Texas. This area is historically and currently unique because of its unsurpassed intensive level of coyote control over such an extensive area.
