Observations on Thinning and Management of Eastern White Pine (Pinus strobus Linnaeus) in Southern New Hampshire

In October, 1905, several permanent sample plots were in the white pine type near Keene, New Hampshire, by the United States Forest Service in cooperation with the Faulkner and Colony Manufacturing Company on lands owned by the latter. The purpose of the investigation was to study some effects of thinnings and of partial (shelterwood) cuttings for establishing natural regeneration. The plots were remeasured in 1909 and again in 1915 by representatives of the United States Forest Service, but after the 1915 measurement they were turned over to the Yale School of Forestry.* In 1920, 1925, 1930, and 1935 the plots were remeasured. Subsequent to the 1920 remeasurement a was published as Bulletin 7 of the Yale School of Forestry, and in 1927 a Second Report appeared as Bulletin· 20 of the same series. More than thirty years have now elapsed since the experiment was started, and the purpose for which it was initiated has in large measure been accomplished. The plots will, however, continue to be maintained as demonstrations of thinning practice and natural seeding

A Progress Report of the Results Secured in Treating Pure White Pine Stands on Experimental Plots at Keene, New Hampshire.

In October, 1905, nineteen permanent sample plots were established in the white pine type near Keene, New Hampshire, by the United States Forest Service in cooperation with the Faulkner and Colony Manufacturing Company on lands owned by the latter. The plots were remeasured in 1909 and again in 1915 by representatives of the United States Forest Service. After the 1915 measurement the plots were turned over to the Yale School of Forestry. In September, 1920, the plots were remeasured for the third time, three additional plots were established and six of the original plots were discontinued. Fifteen years have elapsed since the beginning of the experiments. While the experiments are only partly completed, information of value in reference to the management of white pine has been acquired. The purpose of this publication is to make the information available for foresters and landowners engaged in managing white pine lands

A Second Progress Report of the Results Secured in Treating Pure White Pine Stands on Experimental Plots at Keene, New Hampshire

In October, 1905, nineteen permanent sample plots were established in the white pine type near Keene, New Hampshire, by the United States Forest Service in cooperation with the Faulkner and Colony Manufacturing Company on lands owned by the latter.! The plots were remeasured in 1909 and again in 1915 by representatives of the United States Forest Service. After the 1915 measurement the plots were turned over to the Yale School of Forestry. In 1920 the plots were remeasured for the third time, three additional plots were established and six of the original plots were discontinued. A fourth remeasurement was made in 1925. Subsequent to the 1920 remeasurement a first Progress Report was published as Bulletin NO.7 of the Yale School of Forestry. The last remeasurement (192 5) of the pl()ts furnishes information covering an additional five-year period. Although twenty years have elapsed since their initiation, the experiments still are only partly completed. Little definite knowledge is available as to the results of thinnings in white pine. .For this reason the results and preliminary conclusions secured in the thinning experiments at Keene have been brought up to date and are presented for the information of foresters and landowners engaged in managing white pine lands

The Eli Whitney Forest: A Demonstration of Forestry Practice

This publication has been prepared as a contribution toward solving some of the forestry problems with which owners of woodland are confronted. Forest conditions and details and methods of forest management on one property, the Eli Whitney Forest, are set forth here in the hope that the recital may provide a helpful object lesson

The Den: A Preliminary Report, with Map, of a Tract of Woodland Given to the School by Mr. and Mrs. Winthrop Perry.

In the autumn of 1918, through gift of Mr. and Mrs. Winthrop Perry, the School of Forestry came into possession of a number of closely connected parcels or woodland comprising over 1,300 acres in Farifield County Connecticut. The purpose of the donors and conditions under which the gift was made are clearly stated...

Studies of Connecticut Hardwoods: The Form of Hardwoods and Volume Tables on a Form Quotient Basis

SATISFACTORY volume tables for Connecticut Hardwoods have been . lacking. Considering the fact that the forestry movement within the state started a quarter of a century ago, this condition may seem strange. The scarcity of large bodies of timber, the diverse mixture of species in the average stand requiring several volume tables, and the fact that timber estimating as a business is of relatively lower importance here than in the more heavily timbered regions, account for the failure to develop volume tables. Foresters working within the region have been content to estimate timber by log unit methods or to adapt volume tables made for other localities to fit Connecticut conditions

Studies of Connecticut Hardwoods: The Treatment of Advance Growth Arising as a Result of Thinnings and Shelterwood Cuttings

The typical hardwood stand with which the silviculturist in Connecticut has to deal is even-aged in form. The causes which operated in the past to create stands of this character are thoroughly understood and do not require consideration in this study. That even-aged stands, particularly when densely stocked and composed of comparatively intolerant species, require thinning to develop the most vigorous individuals and to obtain maximum production, is an accepted principle of silviculture. The study separates logically into five parts: 1. A system of classification for the woody vegetation. 2. Amount, character, and distribution of the advance growth and of reproduction arising subsequent to the last cutting. 3. Growth in height of the various elements composing the young stand. 4. Conclusions as to the probable composition of the future stand and the relative value of the individuals which it will contain. 5. Treatment advised to improve the future stand

Artificial Pruning in Coniferous Plantations

The pruning practices here outlined should be applicable on the thousands of acres of coniferous plantations which have been established in southern New England and portions of New York, New Jersey, and Pennsylvania having similar forest conditions

Selection Cuttings for the Small Forest Owner

The purpose of this publication is to indicate to owners of small forests methods of harvesting wood and timber and developing future timber crops which .are likely to prove more profitable than those followed in the past. Cutting practices here described have been applied for some years in the Eli Whitney Forest, New Haven, Conn., where forest areas in various stages of treatment can be ·seen
