Factors in Plant Survival for Revegetation in the Antelope Valley for Particulate Matter Control.

摘要

Research projects conducted to address these problems have identified feasible and affordable land use practices that suppress fugitive dust. Results at this time are preliminary. A project goal is to develop recommendations that will be robust, and apply in this and other low rainfall areas of the arid west. In previous research efforts the authors have demonstrated the long term dust mitigation benefits of revegetation with perennial species. The authors have previously documented the difficulties and uncertainties of successfully reestablishing shrub vegetation in this harsh environment-both cold winters and hot and dry summers. The current project, reported here, documents effects of site modification techniques on plant microenvironment, and examines plant physiological response to the imposed site modifications. Some minimal site modification is likely to be required to enhance the probability of successful establishment to the native shrubs under study. This enhanced probability of success will be essential prior to recommendations to land managers to implement the revegetation protocols under development.
