When forest watershed management research was begun at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire in 1955, we felt certain that at least one aspect of hydrology would not require study-interception. Interception has been studied for a long time, in fact, as early as 1889 (Horton, 1919). It has been well known that a certain amount of rainfall or snow clings to leaves and branches and never reaches the ground.

How shall I cut to get reproduction? What kind of reproduction will I get if I cut the way I am planning to? All foresters have asked themselves these questions. To help supply some answers to these questions for the northern Appalachian hardwood area, the authors have summarized and analyzed before- and after-cutting reproduction data collected over a period of 10 years on the Fernow Experimental Forest near Parsons, West Virginia.

Ten years ago, management was started on two 30-acre demonstration woodlots on the Fernow Experimental Forest near Parsons, West Virginia. These were designated as Farm Woodlots, on the assumption that there was something significantly different between management incentives and opportunities for small holdings owned by farmers and for those owned by non-farmers.

Light, essential in the development of a forest, can be controlled within a stand by silvicultural practices. Measuring it, however, has always been a problem for silvicultural researchers. And accurate measurements are necessary, especially in studying the relation between light and reproduction. The desired objective is to measure the total visible light in specific units at a given place and for a given period in the forest stand. Often it is also necessary to compare the amount of light received at many different places in a forest during the same period. The Integrating Light Meter...

White pine blister rust limits the reproduction of white pine in many areas by killing young trees. In other extensive areas unjustified fear of the disease limits white pine planting. An ability to differentiate the sites on which white pine blister rust (caused by Cronartium ribicola Fischer) might be serious from those on which the disease might cause little damage would be of great value. Sites on which rust will not spread seriously could be recommended for the planting of eastern white pine (Pinus strobus L.) without the expense of eradicating nearby ribes bushes. Likewise, funds...

Since white pine is one of the most desirable tree species for the Lake States region, it is unfortunate that fear of the blister rust disease has greatly limited the amount of white pine planted. Research has shown that, in many areas, loss from the disease has not been great even where pine stands have not been protected through ribes eradication. Conversely, in other parts of the Lake States, present control through eradication has not worked as well as is desirable. This paper presents procedures for specialized blister rust control that will permit growing white pine with minimal...

Snow-depth and water-content measurements were made in March and April 1960 in the vicinity of Paul Smiths, New York, to check on procedures developed the previous year for predicting snow accumulation and melt.

Today a vigorous young stand of aspen and birch, with an understory of softwoods, occupies the Beddington Burn in Hancock County in southeastern Maine.

For many years the lumber industry has been seeking improved methods of preventing decay and insect damage to lumber and other wood products. One relatively new approach to this problem is the addition of toxic chemicals in plywood glues to prevent infestations or restrict feeding injury by wood-boring insects. Wood products treated in this manner have been marketed in some countries, and studies have shown that the toxic additives are effective in preventing certain types of insect damage.
