Observations On Thinning And Management Of Eastern White Pine (Pinus Strobus Linnaeus) In Southern New Hampshire, Ralph C. Hawley
Observations On Thinning And Management Of Eastern White Pine (Pinus Strobus Linnaeus) In Southern New Hampshire, Ralph C. Hawley
Yale School of the Environment Bulletin Series
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 …
The Tympanis Canker Of Red Pine, John Raymond Hansbrough
The Tympanis Canker Of Red Pine, John Raymond Hansbrough
Yale School of the Environment Bulletin Series
A new disease of red pine has recently been found in southern Connecticut, Rhode Island, eastern Massachusetts, western and central New York, northern New Jersey, eastern Pennsylvania, central Ohio, and southern Michigan. It is of serious consequence only on plantation-grown red pine, but it also occurs occasionally on eastern white pine. On the former host it is characterized by axially elongated, annual main-stem cankers which are always centered at the nodes. Infection takes place through adhering lateral dead branches and the growth of the fungus after it gains entrance to the stem.is usually very rapid-Le., cankers up to three feet …
Factors Controlling Initial Establishment Of Western White Pine And Associated Species, Irvine T. Haig
Factors Controlling Initial Establishment Of Western White Pine And Associated Species, Irvine T. Haig
Yale School of the Environment Bulletin Series
The principal object of the study was to determine the roles played by important physical factors of site, chiefly as these vary with overhead shade and hence are within the control of the silviculturist at the time of logging. No special effort was made to study the effect of biotic agents under natural conditions. Indeed, in order to insure as large a sample of seedlings as possible on which to follow losses caused by physical factors, biotic agents were discouraged wherever feasible. But as records of all mortality losses were kept by cause, some information was collected on the activity …

Yale School of the Environment Bulletin Series
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.

Ecological Relations In The Pitch Pine Plains Of Southern New Jersey, Harold J. Lutz
Ecological Relations In The Pitch Pine Plains Of Southern New Jersey, Harold J. Lutz
Yale School of the Environment Bulletin Series
An investigation was undertaken with the primary object of determining the factors responsible for the peculiar development of the vegetation in the Plains community. The conclusion ·is reached that the Plains areas are capable of supporting forest growth similar to that in the Pine Barrens. Inasmuch as the Plains owe their continued existence to repeated fires, it is obvious that effective fire protection is the first and most important step toward their rehabilitation.
Some Aspects Of An Early Expression Of Dominance In White Pine (Pinus Strobus L.), J Lee Deen
Some Aspects Of An Early Expression Of Dominance In White Pine (Pinus Strobus L.), J Lee Deen
Yale School of the Environment Bulletin Series
A series of temporary plots was made for the purpose of observing and noting (1) the factors affecting an expression of dominance of white pine (Pinus strobus Linnaeus) and (2) the relationship between dominance and the development of white pine stands. Twenty natural stands and thirteen plantation stands were studied.

The European Pine Shoot Moth (Rhyacionia Buoliana Schiff.): With Special Reference To Its Occurrence In The Eli Whitney Forest, Roger B. Friend, Allen S. West Jr
Yale School of the Environment Bulletin Series
The European pine shoot moth has been recognized as a pest .in Europe for over a century. It was first discovered in the United States in 1914, since when it has become a serious enemy of red pine. The insect is becoming increasingly abundant in this country and is known to be present in Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, West Virginia, Illinois, Ohio, Michigan, possibly Florida, and in the provinces of Ontario and British .Columbia in Canada. Some fifteen species of pines susceptible to injury in varying degree have been reported as hosts .of this insect, …
Selection Cuttings For The Small Forest Owner, Ralph C. Hawley, Allen W. Goodspeed
Selection Cuttings For The Small Forest Owner, Ralph C. Hawley, Allen W. Goodspeed
Yale School of the Environment Bulletin Series
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.
The Transportation Of Wood In Chutes, Alexander M. Koroleff, Ralph Clement Bryant
The Transportation Of Wood In Chutes, Alexander M. Koroleff, Ralph Clement Bryant
Yale School of the Environment Bulletin Series
Artificial channels, known as chutes, in which logs and bolts may be transported down steep slopes by means of gravity, were devised several centuries ago in the mountainous regions of Europe and later were used by north American loggers, especially in New England, New York, and Pennsylvania. They operate most advantageously on grades that are far in excess of those on which wheeled vehicles or sleds can be used safely, and they are most serviceable for moving timber on terrain which is so steep or broken that the construction cost of suitable roads is prohibitive.
Root Growth Of White Pine (Pinus Strobus L.), Clark Leavitt Stevens
Root Growth Of White Pine (Pinus Strobus L.), Clark Leavitt Stevens
Yale School of the Environment Bulletin Series
Periodic measurements were made throughout two growing seasons to determine the rate of growth in length of lateral roots of white pine, four to six years old, planted in open fields.....Wide variation between individual roots was observed in the amount of growth made annually.
Trenched Plots Under Forest Canopies, James W. Toumey, Raymond Kienholz
Trenched Plots Under Forest Canopies, James W. Toumey, Raymond Kienholz
Yale School of the Environment Bulletin Series
The relative importance of light and soil moisture in particular is better known than that of other environmental factors. We are coming to believe that the nature and condition of the reproduction and other surface vegetation beneath living canopies are not due to any single factor such as light or soil moisture, but to a complex of factors.
