Chemical weed killers have been under test for 3 years as a possible means of preparing planting sites in the scrub oak barrens of Pennsylvania. Here the problem is to kill or set back the competing brush so planted trees can get started without costly release cuttings.

Information about spruce budworm damage in Canadian forests may be useful in reducing losses in Maine if the infestation becomes epidemic there. For this reason the Northeastern Forest Experiment Station has been studying the budworm epidemic in southwestern Quebec since 1945. Since trees are still dying, results of these studies must be considered indicative rather than conclusive.

In tree-breeding operations, it is standard practice to protect the tree flowers with vegetable parchment or sausage-casing bags during the pollination period so no unwanted pollen can get to them. Since the bags often damage the tree, they are usually removed as soon as the pollination period ends - within 2 or 3 weeks.

Pines in the Pine Region of southern New Jersey differ greatly in their rates of growth. In a few areas unthinned stands have grown fast, producing 35-40 cords in 45 years. In such areas dominant pines 7 years old may be 12 feet tall, and early diameter growth be at the rate of 1 inch in 3 years. But in most areas the growth is slow. Pines 25 years old may be only 15 feet tall, and large pines may add only 1 inch to their diameters in 15 years. Volume growth is correspondingly slow.

Before scrub oak lands can be reforested, some cheap and effective way of preparing planting sites must be found. Chemical weed killers have been tried, but they proved to be impractical for general use (see Northeastern Research Note 6).

The Otsego Forest Products Cooperative Association is one of the most successful of the farmers' cooperatives that have attempted to deal with forest products. Now including about 1,000 members, it serves owners of woodlands in the rolling dairy country in and about Otsego County in central New York. The operations of the Otsego cooperative are centered at Cooperstown, which is located at the south end of Otsego Lake, the main source of the Susquehanna River. It is about 60 miles west of Albany.

This Survey Release presents the more significant preliminary statistics on the forest area and timber volume for each of the four regions of Central Kentucky. A similar report has been published for the Western Kentucky region and a release for the eastern region will be issued as soon as field work and tabulations are completed. Later an analytical report for the state will be published which will interpret forest area, timber- volume, growth, and drain statistics in the light of existing and anticipated economic conditions.

This Survey Release presents the more significant preliminary statistics on the forest area and timber volume for the western region of Kentucky. Similar reports for the remainder of the state will be published as soon as statistical tabulations are completed. Later, an analytical report for the state will be published which will interpret forest area, timber volume, growth, and drain statistics in the light of existing and anticipated economic conditions. The field data for this report were collected in cooperation with the TVA Division of Forestry Relations, the Kentucky Division of...

How should old-growth northern hardwoods be managed so as to create stands adapted to continuous yield under the selection system? Since these forests as they occur in the Lake States present an all-aged appearance, it has long been assumed that the single-tree selection could be used in their management.

A cooperative investigation carried on by the Connecticut State Park and Forest Commission and the Northeastern Forest Experiment Station in collaboration with the Northeastern Wood Utilization Council, Inc., the Fitchburg Engineering Company, the Connecticut Highway Department, and the Connecticut Board of Fisheries and Game. The authors acknowledge the generous assistance given by R. G. Bunnell and H. E. Mattern of the Connecticut State Park and Forest Commission.
