In this report forest-area and timber-volume statistics for South-Central, Southeastern, and East-Central Ohio (frontispiece) are shown separately. Regional boundaries were established for the purpose of grouping counties with similar forest, soil, geologic, or economic conditions. This report covers the unglaciated, hill region of the State.

Foresters sometimes have to estimate the volume of timber harvested from the stumps that remain after logging. Such estimates may be needed when the timber cutters have crossed property lines or when they have removed trees not marked for cutting. Stump measurements on sample areas may also be used for state or regional estimates of the volume of timber cut annually, instead of the usual timber-production survey. In order to test this stump method of estimating volume of timber harvested, the Central States Forest Experiment Station has been tallying stumps on field sample plots for...

Sills and joists of basementless houses on wet sites are subject to decay. Moisture vapor rising from the soil will condense on wood during cold weather (fig. 1). If the wood stays wet, fungi attack it and ultimately cause decay and possibly structural failure.

Fifty years ago the chestnut blight (Endothia parasitica) was discovered in New York City. Since then the American chestnut (Castanea dentata) has practically disappeared from our forests.

A need to estimate the volume cut from a timber tract when only the stumps are left is often felt by foresters, timber operators, and landowners. This need arises in areas where timber sales are based on stump diameters, in timber trespass cases, in check cruises on marked timber sales (to determine volume cut from unmarked trees), and as an aid in piecing together the history of cutover lands as a step in forest-management work.

Hybrid poplar plantations are established by planting dormant cuttings in close spacing, usually 4 x 4 feet. They are cultivated during the first growing season to eliminate competition from grasses and weeds. After the first year, the more vigorous trees effectively shade out lower vegetation. But rapid tree growth often makes thinning necessary after 2 or 3 growing seasons.

Most of the forest land in the white pine region of the Northeast is owned in relatively small blocks or woodlots. The way these many small woodlots are managed can affect the forest economy of the entire region. Good forest management can increase the owner's income and provide more and better raw material for the wood processing industries.

In connection with a seedbed-preparation study, a census of the mouse populations on several areas on the Penobscot Experimental Forest near Bangor, Maine, was made in October 1953.

Regeneration after clear-cutting second-growth northern hardwoods is often unsatisfactory, in both quantity and species composition. A small area on the Bartlett Experimental Forest near Bartlett, N.H., provides a good example.

Stands of mixed oaks and yellow-poplar form the most valuable forest crop on many sites in central and northern New Jersey and in the Delaware Valley of southern New Jersey. However, these stands often contain shrubs and low-value hardwood trees that prevent satisfactory restocking of cutover areas.
