Four O.h most other perennial grasses were not greatly affected. Results suggest that periodic burning can maintain a grassland aspect if the intensity and frequency of grazing allow enough dry herbagefor an effective fire to accumulate between bums. A common question in southern Arizona is: can fire be used to control such plants as velvet mesquite (Prosopis julijoru var. velutinu), cholla and prickly pear cactus (Opuntiu spp.), and burroweed (Applopappus tenuisectus) that now occupy former grasslands (Humphrey 1949)?1 This report describes the effects of fall (November) burning on velvet mesquite, other shrubs, and herbaceous vegetation in: (1) undisturbed invasion stands of mesquite, and (2) stands of young mesquites that have come in since the invasion stand was killed with sodium arsenite in 1940. The sites were relatively free of mesquite in 1903 whenthe “Range” was fenced out of the Public Domain.
