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
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.
Some Aspects Of Soil Moisture In The Forest, Ian J. Craib
Some Aspects Of Soil Moisture In The Forest, Ian J. Craib
Yale School of the Environment Bulletin Series
By determining the moisture content of carefully selected soil samples taken at various depths down to three feet, the moisture content of soils in the forest and in the open have been compared. The soils investigated were similar in their mechanical properties. Part I is an investigation of the effect of forest cover on the amount of water in the soil over the growing season and its availability. Part II is an investigation of the effect of root competition on the available water supply of forest soils.

In 1913 the Yale School of Forestry came into possession of certain parcels of land located near Keene, New Hampshire. This land amounting to 629.4 acres was presented to the School as a nucleus for a school forest to be used for purposes of instruction and research. Subsequently in March, 1915, additional lots comprising 270.9 acres were purchased with funds contributed by the original donor. The present area totals 900.3 acres and is know as the "Keene Forest."
