Book excerpt: In 1948, the Northeastern Forest Experiment Station, in cooperation with the Pennsylvania Department of Forests and Waters, started a long-term watershed study in a scrub oak area on the Pocono Plateau. The experimental area, comprising about 2,000 acres, was designated as the Dilldown Unit of the Deleware-Lehigh Experimental Forest; it will be referred to hereafter in this paper simply as Dilldown. The study called for conversion of the shrubby cover to a cover of true tree species after a 5-year or longer period for calibrating the watershed. In some places, where sprouts of tree species were abundant, the conversion was to rely on natural growth under fire protection. Elsewhere--on more than one-half the area--conversion was to be accomplished by planting. Experiments were started in 1948 to determine how the planting should be done. The results and implications of those experiments are summarized in this paper. Beginning in 1955, conversion plantings on the Dilldown watershed, and subsequently in several other locations, were done by methods developed in the experiments. The results in these action programs also will be briefly described.
