Preliminary Estimates Of Bark Percentages And Chemical Elements In Complete Trees Of Eight Species In Maine, Harold E. Young
Preliminary Estimates Of Bark Percentages And Chemical Elements In Complete Trees Of Eight Species In Maine, Harold E. Young
Aspen Bibliography
Five tables were prepared to show the relative amount of bark on each of the tree components, the concentration and range of 12 chemical elements in the bark of each tree component, the proportion of each of the chemical elements in the bark of that element in the complete tree, and the proportion of each element in the bark as compared to the wood and bark of the merchantable bole. There is an overall 4:6:1 wood to bark ratio, but due to the higher concentration of the elements in the bark, the proportion of the elements in the bark is …

Measurement Of Throughfall At Two Levels In A Young Aspen Stand, J.R. Clements
Measurement Of Throughfall At Two Levels In A Young Aspen Stand, J.R. Clements
Aspen Bibliography
The purpose of this report is to compare measurements of the quantity of throughfall at two different heights above ground level in a seven-year-old sucker stand of largetooth aspen (Populus grandidentata Michx.) This comparison defines the influence rain splash from the forest floor has on the quantity of throughfall catch of trough rain gauges placed on the forest floor.
Net Rainfall In A Multi-Storied Aspen Forest Community, J.R. Clements
Net Rainfall In A Multi-Storied Aspen Forest Community, J.R. Clements
Aspen Bibliography
This paper presents mathematical equations describing the relationships between the amount of net rain per storm under each crown canopy and the amount of gross rain per storm in a multi-storied forest community. The relationships were curvilinear and accounted for gradual filling of the storage capacity of the vegetation. The rate of increase of net rainfall was successively less for each crown canopy in turn starting with the uppermost canopy in the forest. The equation coefficients varied in respect of the position of the crown canopies in the vegetal profile and also in respect of variations in vegetal structure within …

Review Of Silvicultural Research: White Spruce And Trembling Aspen Cover Types, Mixedwood Forest Section, Boreal Forest Region, Alberta-Saskatchewan-Manitoba, J. M. Jarvis, G. A. Steneker, R. M. Waldron, J. C. Lees
Aspen Bibliography
The Department of Forestry has been carrying on silvicultural research in the white spruce (Picea glauca (Moench) Voss) and trembling aspen (Populus tremuloides Michx.) cover types in the Mixedwood Forest Section of Alberta, Saskatchewan and Manitoba for about 40 years. Because of the needs of industry most of this research has been focused on spruce, and only as small portion on aspen. Much of the research is concerned with basic problems and the findings in one area may be applied directly or with minor modification throughout the entire Mixedwood Forest Section. Only a minor part of the total …

Cacodylic Acid As A Silvicide, Maurice W. Day
Cacodylic Acid As A Silvicide, Maurice W. Day
Aspen Bibliography
This report deals with the effectiveness of cacodylic acid (dimethylarsenic acid) as a silvicide for undesirable trees. Cacodylic acid has been used successfully as an herbicide for the destruction of grasses and weeds. Experimental work with this material was begun during the 1963 field season, and continued during 1964, to permit complete evaluation of the results. It appears that cacodylic acid has considerable potential as a silvicide.

Some Aspects Of Regeneration Silviculture In Spruce-Aspen Stands In Alberta, L. A. Smithers
Some Aspects Of Regeneration Silviculture In Spruce-Aspen Stands In Alberta, L. A. Smithers
Aspen Bibliography
Surveys of spruce-aspen stands in Northern Alberta have shown that natural regeneration of white spruce is generally a failure on areas which have been logged but not burned (Candy 1951).

Aspen Bibliography
Swedish experience with the genetic improvement of the European aspen (Populus tremula L.), a species which is closely kin to our North American quaking aspen (P. tremuloides Michx.), suggests that the rate of volume increment and the length of fiber tracheids might both be increased in North American aspen by finding or producing trees which possess a triple set, rather than the usual double set, of "chromosomes". Chromosomes (Figure 1) are found within and inner region--the nucleus--of each of the millions of cells formed during the growth of a tree.

Aspen Defiberization And Refining Of Product, Robert Craig Jr.
Aspen Bibliography
Because of the great demand for wood fiber and because there is an abundance of aspen available1/ for this purpose, its conversion into a usable fiberized material offers possibilities. It also affords an outlet for low-quality bolts developed in any aspen logging operation or from land of poor quality.
Aspen Properties And Uses, Zigmond A. Zasada
Aspen Properties And Uses, Zigmond A. Zasada
Aspen Bibliography
Because of the large demand for lumber during the last 10 years, and particularly during the war period, aspen has entered many new fields of use. At present there is widespread interest in the possibilities of building new industries and extending the life of old ones by increased use of aspen. Many people are interested in becoming familiar with this wood. This report has been prepared to give general information on the properties and present uses of aspen and also to help in correcting some of the existing erroneous ideas about this wood.
Seeding Grass On Deteriorated Aspen Range, A. Perry Plummer, George Stewart
Seeding Grass On Deteriorated Aspen Range, A. Perry Plummer, George Stewart
Aspen Bibliography
The herbaceous undercover on much of the aspen range in the Intermountain region is badly deteriorated. These areas, naturally highly productive, when revegetated can contribute greatly towards a much needed supply of range forage. One of the major obstacles to successful seeding has been the difficulty of getting the seeds covered with soil since both standing and fallen trees interfere with the use of drills, harrows, or other machinery. In the search for methods to overcome this difficulty, it was found that for open aspen stands the covering of seeds is unnecessary when the right precautions are taken in other …
