“…1). During the period of herbaceous production measurement (1998)(1999)(2000), the site experienced 3 consecutive below normal years that had not occurred since 1977. During 1998-2000 Mesquite Responses, 1998 By 1998, mesquite canopy cover was significantly greater in the C30 and T20 treatments than the R20 and R10 treatments (Fig.…”

“…Numerous studies have estimated herbage production following chemical treatment of mesquite, but few have monitored production more than 2 or 3 years following treatment (Scifres and Polk 1974, Scifres et al 1977, Dahl et al 1978, Bedunah and Sosebee 1984, Heitschmidt and Dowhower 1991, Warren et al 1996, Laxson et al 1997. In addition, an understanding of individual species or species functional group responses to treatments both beneath mesquite canopies and in interstitial spaces between mesquite is key to developing ecological and economic models that accurately predict landscape responses to mesquite treatments (Brock et al 1978, McDaniel et al 1982.…”

Long-term herbaceous response data following herbicidal treatment of honey mesquite (Prosopis glandulosa Torr.) are needed to develop more accurate projections regarding economic feasibility of these treatments and to model ecological interactions between woody and herbaceous plants in rangeland systems. Our objective was to measure herbaceous yield and mesquite regrowth 10 or 20 years after mesquite was aerially sprayed with either mesquite top-killing or root-killing herbicides. Treatments evaluated included mesquite top-killing herbicides at 10-12 years (T10) and 19-21 years (T20) post-treatment, mesquite root-killing herbicides at 10-12 years (R10) and 19-21 years (R20) post-treatment, and an untreated control where mesquite were >30 years old (C30). Treatments were applied in the late 1970's or late 1980's. Grass yields, measured annually from 1998 through 2000, were quantified within patches of 3 perennial grass functional groups: cool-season mid-grasses, warm-season mid-grasses, or warm-season short-grasses. Coolseason annual grass yields were also quantified within these perennial grass patches. By 1998, mesquite canopy cover was 55, 47, 36, 24, and 12% in C30, T20, T10, R20, and R10 treatments, respectively. Warm-season mid-grass yields were most sensitive to differences in mesquite cover in all 3 years and declined sharply when mesquite cover exceeded 30 %. Cool-season midgrass yields declined slightly with increasing mesquite cover. Warm-season short-grass and cool-season annual grass yields were not related to mesquite cover, except in 2000 when warmseason short-grass yield beneath mesquite canopies increased with increasing mesquite cover. Results suggest that herbicide treatment life (defined by increased perennial grass yield in response to mesquite treatments) was at least 20 years for the root-killing herbicide, but no longer than 10 years for the topkilling herbicide.

“…1970). Considerable research has emphasized improved honey mesquite control methods (Bovey and Meyer 1974;Fisher et al 1970;Scifres 1973;Scifres et al 1977;Wiedemann et al 1977) but there is relatively little published information concerning the economic efficiency of these methods. Some workers have evaluated treatment costs (Boykin 1960;Wiedemann and Cross 1975) but did not consider benefits of brush control because of the lack of production response data amenable to economic analysis.…”

Although economic responses to honey mesquite control varied considerably within and among resource regions in Texas, aerial applications of herbicides generally produced higher annual rates of return on the investment than did mechanical alternatives. Statewide, aerial applications of 2,4,5-T produced the greatest annual rates of return, averaging 15.7% for deep range sites and 11.0% for shallow range sites for projected livestock responses when cattle prices were estimated to average %0.97/kg (%44.00/cwt, 1978 dollars). Statewide, annual rates of return from aerial application of herbicides for honey mesquite control on shallow sites (statewide) varied from-8.3% to l&l%, based on the ! §0.97/kg livestock price. When cattle prices were varied from $O.S2/kg (%37.00/cwt) to $l.O5/kg (%47SO/cwt), annual rates of return from aerial application of 2,4,5-T to deep sites on the Rolling Plains and Rolling Red Plains of Texas ranged from 9.6% to 17.9%. Chaining of honey mesquite on deep sites of the Rolling Plains and Rolling Red Plains proiluced rates of return from 7.1% to 12.5%. While the economic feasibility of herbicides in general was determined to be greater than that from the use of mechanical practices, rates of return from herbicides are more price sensitive than mechanical treatments. Over the 20-year planning period, tame pastures in the Rolling Plains produced the greastest accumulated net present value ($/ha) when the annual interest rate charged to the added investment was 5% or less. When the annual interest rate was 7% or 9%, the net present values of herbicide treatments exceeded those of the mechanical methods. The Texas range livestock industry faces perennial economic problems because of unstable markets, inevitable drought, increasing taxes, livestock losses from predators and poisonous plants, and rising production costs. Economic pressures have forced many ranch firms to increase breeding herd numbers and reduce fixed costs to increase profit potential. However, most ranchers have limited means for increasing land holdings by purchase or lease because of the limited availability of lands and the relatively low
