Herbage Response to Sagebrush Spraying
نویسنده
چکیده
Information that is presently available makes chemical control of sagebrush (Artemisia’ tridentata) a practical operation. Yet additional information is needed regarding ecological responses to assure that the practice of spraying for sagebrush control will be used wisely. The economy of brush control must be determined by the amount of forage and meat products gained; however, the principal objective in brush control should be an upgrade in range condition. An evaluation of returns consistent with this management objective will require a long period of study, but’ the practical application of chemical control methods will not wait for such extensive experimentation. Therefore, sagebrush control measures must be undertaken in a manner consistent with present knowledge. Information from previous work and experience has been evaluated in terms of how, when, why, and where to control sagebrush in a recent bulletin by Pechanec and others (N54). Preliminary details of herbage response to chemical sagebrush control, and its relation to site selection, will contribute to this back-log of information. The present paper presents three years of results in herbage response to sagebrush spraying. The amount of forage and meat products resulting from sagebrush control, and the range condition at the time of spraying will be of interest

متن کاملStocking rate, precipitation, and herbage production on sand sagebrush-grassland
Knowledge of the relationship between stocking rate or grazing intensity and plant production is fundamental to the sustainable management of rangelands. The general management paradigm is that plant production declines as stocking rate increases. Our objective was to determine the impact of stocking rate on herbaceous production of a sand sagebrush (Artemisia filifolia Torr.)grassland. Stockin...

Sagebrush (Artemisia L.) taxa historically functioned as the keystone species on 1 090 000 km of rangeland across the western United States, and Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle and Young) is or was dominant on a substantial amount of this landscape. Wyoming big sagebrush provides habitat for numerous wildlife species. Nevertheless, Wyoming big sagebrus...
متن کاملComparing burned and mowed treatments in mountain big sagebrush steppe.
Fires in mountain big sagebrush [Artemisia tridentata spp. vaseyana (Rydb.) Beetle] plant communities historically shifted dominance from woody to herbaceous vegetation. However, fire return intervals have lengthened with European settlement, and sagebrush dominance has increased at the expense of herbaceous vegetation in some plant communities. Management actions may be needed to decrease sage...
