Fourwing Saltbush Revegetation Trials in Southern Arizona

Highlight Fourwing saltbush was seeded and transplanted into native stands of (a) almost pure creosotebush and (b) velvet mesquite with burroweed understory, in southern Arizona. Burroweed and creosotebush were controlled by picloram spray and by grubbing. The mesquite was killed on half of the burroweed plots. Establishment and survival of saltbush was much higher on the creosotebush site than on the mesquite site, presumably because the calcareous (pH 8.0+) soil at the creosotebush site was

Transplants survived much better on grubbed plots than on sprayed or check plots, and seedlings on sprayed or grubbed plots than on check plots. However, after 3 years the stands were reduced to 650 and 46 plants per acre on the creosotebush and mesquite-burroweed area respectively. Fourwing saltbush (A triplex canescens (Pursh) Nutt.)s is one of the most widely distributed and important shrubs on western ranges. It has been used for revegetation many times with varying degrees of success. Springfield (1970) presents a thorough summary of the present state of knowledge relating to the germination and establishment
