  1. Development of second-growth northern hardwoods on Bartlett Experimental Forest - a 25-year record

    Second-growth timber occupies more than one-third of the commercial northern hardwood forest land in New England. The origin of these stands - clearcutting, or land abandonment with or without fire - determined their present characteristics; they are essentially even-aged, with a high proportion of intolerant and intermediate species and many stems of sprout origin (...

  2. Screening tests of chemical deterrents

    Despite intensive research and zealous control efforts, the Dutch elm disease continues to kill valuable ornamental and wild elm trees over wide areas in the United States and Canada. Control of the disease at present is based on sanitation, the removal of dead and dying ornamental trees, and use of insecticides to kill the insects that carry the disease. The primary...

  3. Interception of precipitation by northern hardwoods

    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...

  4. Prescribed burning in the pine regions of southern New Jersey and eastern shore Maryland - a summary of present knowledge

    Twenty years ago the deliberate use of fire in forest management was frowned upon by many foresters. Many heated arguments developed over it, even though ecological studies had shown that fire favored the maintenance of several valuable forest types. Today attitudes have changed: most foresters accept fire as one of their management tools - though admittedly it is...

  5. Thinning balsam fir thickets with soil sterilants

    Under certain conditions that we do not yet fully understand, balsam fir has a tendency to form dense thickets that cause stagnation of growth. This condition is common throughout the spruce-fir region, and it presents the landowner with one of his most perplexing management problems. A typical thicket averaging 15 feet tall may contain 5,000 to 10,000 stems per acre (...

  6. Effect of seedbed preparation on natural reproduction of spruce and hemlock under dense shade

    The cutting practices commonly recommended for spruce-fir stands in the Northeast involve uneven-aged management. The success of this type of management is predicated upon stand structures that have a range of size classes from seedlings to mature trees in intimate mixture. This kind of stand structure requires a continuous supply of reproduction of desirable species....

  7. Mice and voles prefer spruce seeds

    When spruce-fir stands in the Northeast are cut, balsam fir seedlings often predominate in the regeneration that follows. Most landowners would prefer to have the spruce; but they do not get it, and they wonder why.

  8. Silvical characteristics of beech (Fagus grandifolia)

    Of all the trees in our forests, the beech somehow always stands out. Its clean, smooth, sculptured blending of bole and branch gives it a form that is unique. Also unique is its smooth gray bark, which does not become furrowed with old age as that of other trees, but remains smooth from ground to crown.

  9. Tree planting in the Allegheny section

    Tree planting involves many considerations - site classification, selection of species, planting practices, and protection from fire, insects, and diseases. The information about many of these aspects of planting is scattered and fragmentary.

  10. Managing mountain hardwoods - a ten-year appraisal

    Ten years ago - in 1949 - four 5-acre plots were established on the Fernow Experimental Forest near Parsons, West Virginia, to show the effects upon mountain hardwoods of each of four management treatments.

  11. Average growth rates in the spruce-fir region of New England, based on remeasured plots

    The fact that trees grow makes the extraction of logs and bolts from a forest different from the extraction of ore from a mine. Every mine has a limit, and sooner or later it must be abandoned, either because the vein has run out or because the mine has become too costly to operate. But a properly managed forest - one where cutting maintains production - never becomes...

    The International Union of Forest Research Organizations (IUFRO) has sponsored several international provenance tests. This is a report on the practical aspects of an IUFRO provenance test with Scotch pine in New York.

  13. A chemical light meter for forest research

    Light is one of the most important factors that influence the growth and development of forest trees. Not only is light necessary for the basic process of photosynthesis; light also regulates and modifies other factors of the environment such as temperature and moisture. Yet despite the importance of light, few investigators have succeeded in measuring it adequately in...

  15. Effect of seedbed condition on regeneration of Virginia pine after logging

    When stands of Virginia pine (Pinus virginiana ill.) are cut according to usual practices, and no specific action is taken to control subsequent regeneration, the pine often fails to reproduce. A common cause for failure is an unfavorable seedbed condition: logging leaves much of the seedbed undisturbed, and some areas that are disturbed are covered...

  16. Lumber or chips? A comparison of small-log utilization alternatives

    A sawmill in the Northeast commonly receives a number of small low-quality logs. They may be among logs purchased from independent loggers, or timber-sale specifications may require that the sawmill take them. Some mill operators confronted with logs of this kind consider handling them as part of the cost of obtaining their log supply. Others may feel that, since the...

  17. Ten-year earnings from two small woodlands

    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.

  18. Introducing white pine into poor-site hardwood stands in West Virginia

    Poor hardwood land presents a problem that is only too well known: what to do with areas in hardwood country that support only stunted, slow-growing trees? This is a question that vexes foresters and landowners in many parts of West Virginia and neighboring mountainous areas of Maryland and Virginia. On these poor sites, it is doubtful whether the hardwoods can pay the...

  19. Ash dieback in the Northeast

    A dieback condition among our ash trees is causing great concern among foresters and forest industries in the northeastern United States. There is good cause for concern. For example, a recent survey made by the New York Conservation Department in 18 eastern counties of the State revealed that about 70 percent of the woodland ash trees are dead or dying.

  20. Fomes annosus - what it is and how to recognize it

    The fungus Fomes annosus has caused a great deal of damage to coniferous forests and plantations in Europe. The disease caused by this fungus is now widespread in the United States. In the past few years we have become increasingly aware of its threat in the Northeast. It is particularly damaging to 20- to 30-year-old conifer plantations on formerly...
