Summary
In a semi-arid honey mesquite P.glandulosa/mixed brush community (livestock grazing ended in 1988), an 80 ha area was divided into two for growing season (July-August) or dormant season (January-February) prescribed burning. Each 40 ha area was subdivided into three 13 ha plots, each plot randomly assigned one of three treatments applied 1991 through 1995:
Twenty-four woody shrub and tree species (cover 40 to 65%) were present within the plots; honey mesquite was dominant (17-44% cover). Although each plot had somewhat different species composition and cover, there was little change in woody vegetation in response to any treatment. Shrubs in this community typically resprout after fire. The only mortality was of some small shrubs or saplings (diameter < 3 cm), and large trees with woodrat Neotoma micropus nests at the base which allowed burning throughout the root crown.
