Three or more annual sprays are required to eliminate Japanese honeysuckle where 2,4-D, a mixture of 2,4-D and 2,4,5-T, or amitrole is applied as either a low-volume (mistblower) or high-volume spray. Dicamba and picloram are more effective. The mixture of 2,4-D and picloram is recommended as the best material for eliminating honeysuckle in a single treatment at the time of harvesting overstory trees. However, 3 gallons of the material, costing about $33, are required per acre.

Small seedbeds were established on three newly cutover areas on the Allegheny National Forest. Site preparation, protection from animals, and season of sowing were studied. It was not necessary to prepare the site or to provide protection to obtain good germination. Seedlings exposed to deer browsing were severely limited in height growth. Best height growth on the protected seedbeds was obtained on seedbeds that were burned with added fuel.

In a study of birch regeneration in New Hampshire, soil moisture and temperature were found to be intimately related. Not only does low moisture lead to high temperature, but high temperature undoubtedly accelerates soil drying, setting up a vicious cycle of heating and drying that may prevent seed germination or kill seedlings.

A report on results of sawing 556 northern red oak sawlogs at four sawmills in West Virginia and Virginia, and the distribution of grades for the standard factory lumber produced. Tabular data on actual yield and curved grade-yield percentages.

This is a report on the second in a series of annual surveys of pulpwood production in the 12 Northeastern States - Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and West Virginia.

Pulpwood production continued to rise in 1965, for the third straight year. Production of all forms of pulpwood in the 14 Northeastern States' totaled 5,122,800 cords in 1965. By comparison, the 1964 production of pulpwood for all 14 states amounted to approximately 4,579,000 cords. The 1965 total is a gain of nearly 543,800 cords-12 percent over 1964 production.

Under the authority of the McSweeney-McNary Forest Research Act of May 22, 1928, and subsequent amendments, the Forest Service, U. S. Department of Agriculture, conducts a series of continuing forest surveys of the states to provide up-to-date information about the forest resources of the Nation. A resurvey of the timber resources in Maryland was made in 1962-63 by the Northeastern Forest Experiment Station, approximately 14 years after the initial forest survey. In this resurvey, as in the initial survey, the Northeastern Station again received cooperation from the Maryland Department of...
