Effectiveness of Best Management Practices to Reduce Soil Compaction Around Trees in Construction Sites.

Soil compaction from vehicular traffic around existing trees in construction sites is a major issue resulting in high tree mortality rates. Although some BMP recommendations are available, their effectiveness in reducing soil compaction has not been tested. A study was conducted to evaluate the usefulness of three available BMPs on reducing soil compaction. The impact of repeated traffic was also assessed. Preliminary data shows that these BMPS are somewhat effective in avoiding soil compaction, but avoiding or reducing vehicular traffic around trees altogether is still a better option.
