S2Disking in another possible mechanical treatment, and it has the merit of not disturbing the natural drainage. However, up to the middle 1950s, disking had not been tried on the Eastern Shore. Since disking seemed to offer advantages over bulldozing, a study was started in 1956 to determine its effectiveness. Some of the questions we hoped to answer were: How intensively should an area be treated? What species and stem sizes of hardwood trees and shrubs are eliminated? Which ones are only set back and soon recover? How fast do these recover? (i.e. how long after treatment can pine seedlings start and still become dominant?) This report describes what we learned about these questions and about the role of disking in Eastern Shore timber management.S3.
