Most currently available remediation technologies are uneconomical due to large inputs of energy, fertilizers, herbicides adn labor or are ecologically ineffective due to harsh environments adn the highly competitive nature of these native shrubs.  Our analysis of these historical remediation technologies together with new information on ecosystem processes has led us to pursue an ecologically-based approach in which more limited inputs are targeted to promote natural processes of regeneration.</style></abstract><accession-num><style face="normal" font="default" size="100%">LTER.1997-91360</style></accession-num></record></records></xml>
