Description

The Rio Grande plains of South Texas is the southern-most extension of the Great Plains grasslands. Fire, along with other climatic variables such as drought, presumably maintained the honey mesquite (Prosopis glandulosa) savannas and interspersed grasslands of pre-European settlement in South Texas (Scifres and Hamilton, 1993). Frequency of fire appeared to be highly variable and ranged from 5 to 30 years (Wright and Bailey, 1982). Following European settlement, suppression of fire combined with heavy grazing by livestock has lead to the current thorn woodlands common throughout southern Texas (Archer et al., 1988; Archer, 1994). Beginning in the mid-20th century, landowners in South Texas began to convert thorn woodlands back to grasslands to enhance rangelands for livestock production. Mechanical treatments such as root plowing were commonly used methods for achieving this goal. Mechanical brush-manipulation practices can significantly reduce woody plant cover while increasing herbaceous vegetation (Scifres et al., 1976; Bozzo et al., 1992). However, upon recolonization by woody species, their diversity may be dramatically reduced (Fulbright and Beasom, 1987; Ruthven et al., 1993), which may negatively impact diversity of wildlife.
