Using the climax forest as a guide to growing the species best suited to the climate and the site, the author offers a silvicultural system for managing the spruce-fir forests of eastern North America. Based on ecological principles, such silviculture is aimed to bring about forests that are inherently healthy and have a natural resistance to insects and disease.

The Forest Survey is conducted in the various regions by the forest experiment stations of the Forest Service. In Indiana the project is directed by the Central States Forest Experiment Station with headquarters in Columbus, Ohio. This Survey Release presents the more significant preliminary statistics on the forest area timber volume, timber growth, and timber drain for the State of Indiana. Later, an analytical report for the State will be published which will interpret statistics on forest area, timber volume, growth, and drain in the light of existing and anticipated economic conditions.

Almost all hardwood trees in the forests of the Missouri Ozarks are prolific sprouters. This ability plays an important role in the development of both managed and unmanaged forests. The ability to sprout is a big help in maintaining a forest cover. It is primarily responsible for the very existence of most of the hardwood forests in the Ozarks today. Persistent attempts for more than half a century to clear land have been unsuccessful on about half the original forested area in the State. These attempts, although unsuccessful in eliminating the forest cover, have drastically reduced the...

Over the years there has been a small but impportant amount of research in forest genetics in the Lake States, and recently there has beeen a growing awareness of the importance of tree improvement in this region. For these reasons it appeared that a meeting of people active or interested in forest genetics might be worth while. So after consultation with a number of foresters and geneticists in Minnesota, Wisconsin, and Michigan, we decided to sponser a Lake States Forest Genetics Conference at Eagle River, Wisconsin, on March 31 and April 1, 1953.

In the nineteen twenties the hardwood lumber industry of the Lake States faced a critical decision. There was an excess of mill capacity over stumpage available for long-continued operations. Some mills had a limited future; others had enough timber to last them a long time. But all such concerns began to consider what the future held.

Since the earliest colonial settlements along the northeastern seaboard, wood piling has been used for wharves and piers and other waterfront structures. As waterside industries and waterborne commerce grew, the demand for wood piling grew.

Aerial photographs are now commonly used in forest-inventory work. In the forest-survey work of the Northeastern Forest Experiment Station we are interested most in using them to estimate total volume of a forested area.

The nationwide forest survey now underway was undertaken to determine the status of the Nation?s forest resource. The purpose of the survey is, in brief, to find out how much timber there is, and where it is, the drain on this resource, and how much of the drain is being replaced by new growth.

Most published observations on the flowering and fruiting habits of forest trees have dealt with the periodicity of fruiting in entire species. This is natural since the main reason for making such observations has been the forecasting of seed crops.
