In most forest-management plans, attention is usually directed to certain cultural treatments early in the life of a stand. These are generally some form of weeding or thinning to favor the ultimate crop trees by cutting out a proportion of the young stand that seems least desirable to retain.

Timber is an important resource in Ohio, and cutting records are an essential part of a forest resource appraisal. However, finding out just how much timber is cut in the State during any one year is a big job. Occasionally in the past, wood-using industries have been surveyed to determine the volume cut by species and product, but the variety of industries, the large number of small operations (including individual farmers) and lack of systematic records at small mills, makes an industry production survey difficult and costly. Production varies from year to year, so an industry survey for...

I am firmly convinced that the Lake States Forest Tree Improvement Committee, and similar groups in other regions, can play an important role in encouraging and coordinating research and other activities in forest genetics. As this new field of work continues to expand, which it assuredly will, it will become of increasing importance to maintain close liaison among the agencies engaged in it. For this reason our Station is glad to participate in and to further the work of this Committee.

This is the fifth report on a series of studies to show the relationship of stump diameter to diameter breast high (d.b.h.) for commercially important tree species in the Northeast. This report is for northern red oak (Quercus rubra).

Foresters and others who engage in woods work find it desirable at times to have information about the size class of trees that are cut for various products.

One of the most serious problems in spraying trees to control insects and diseases has been to obtain a sufficient deposit in the upper parts of tall trees.

Fire has often been used as a silvicultural tool in managing most of the southern pines. At present, however, there is not enough evidence to show whether similar techniques can be used in Virginia pine stands. The purpose of this note is to offer some observations on how a wildfire affected a young pine-oak stand.

One of the commonly recommended methods for deadening weed and cull trees for timber-stand improvement is by use of ammate crystals in ax notches or cups spaced about 6 inches apart around the base of the tree.

The eye of Hurricane Hazel passed to the west of the Beltsville Experimental Forest in Maryland on the afternoon of October 15, 1954. Sustained wind velocities of 66 mph (from the SE), with maximum gusts of 98 mph, were recorded nearby.

Planting experiments during the past 7 years on the Dilldown Unit of the Delaware-Lehigh Experimental Forest in Pennsylvania and elsewhere in the scrub oak type have been aimed at finding methods for converting the scrub cover to more valuable timber types at least cost. Some sort of site preparation has been recognized from the beginning as essential to successful planting on much of the scrub oak land.
