Ueckert, D. N.; Wright, H. A.
Wood boring insect activity in mesquite wood is of interest to fire ecologists because infested trees are much easier to burn down than uninfested trees. Wood borer tunnelling in mesquite killed by six different methods was compared over a 2-year period. Basal spraying with diesel oil + 2,4,5-T and girdling resulted in significantly more tunnelling by wood borers. Borer activity was intermediate in trees killed by basal spraying with diesel, and by burning; slight in felled trees (simulated chaining or root-plowing); and insignificant in trees top-killed by 2,4,5-T spray and in the control. Ranchers planning to use prescribed burning as a method of removing dead mesquite stems from rangeland previously treated with conventional mesquite control practices could expect a high degree of wood borer activity, and hence a greater burndown in pastures where trees have been killed in previous years by basal spraying with diesel oil + 2,4,5-T. Wood borer activity will be substantial for good burndown in trees top-killed by basal treatment with diesel oil and by burning.

McMahan, C. A.; Inglis, J. M.
The relative use of 11 major brush types and a rootplowed area by white-tailed deer was studied on the San Pedro Ranch in Dimmit County, Texas. The mesquite drainage, hackberry drainage, and guajillo scrub types were preferred by deer in fall, winter, and spring. In summer, the mesquite drainage was preferred and all other types were used about equally. The granjeno drainage, rootplowed, and mesquite savannah types were used least. The preferred brush types occurred on sandy loam soils. The composition, density (within a range of tolerance), structure, and phenology of brush were not important factors influencing selection of types by deer. The quality of typical brushlands as deer habitat appeared to be largely a function of range site. Range sites capable of high gross production of herbaceous plants deserve consideration for their value to deer in brush clearing schemes. Some brush should be left intact as screening cover on such sites to insure continuing deer populations on ranches practicing brush control in the Rio Grande Plain.

Thilenius, J. F.; Glass, G. B.
Wyoming ranks second in the nation in strippable coal resources, with at least 18.9 billion tons of coal presently recoverable. Mining this coal could disturb about 590 square miles (0.6%) of the state's land area. The presence of this disturbed land offers a challenge to, and opportunity for, the varied fields of renewable resource research and management to practice their sciences and arts to allow the nation to use the coal without lasting detrimental effects on other resources.
