Prescribed Fire and Herbicide Modify Soil Proceses During Barrens Ecosystem Restoration

摘要

prescribed fire has become a common tool of natural area managers for removal of invasive species and maintenance of barrens grassland communities. Certain target species however, resist fire and may require additional removal treatments. We studied changes in soil N and C dynamics following prescribed fire and herbicide application in a remnant barrens in west-central Kentucky. The effects of a single spring burn, post-emergence herbicide, the treatments in combination, and an unburned, no-herbicide control were compared in a 2 way factorial design iwth 5 replicates. Fescue cover decreased and bare soil increased from near 88 and 2
