Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Aspen Bibliography
The ability of quaking and bigtooth aspens (Populus tremuloids Michx., P. grandidentata Michx.) to vegetatively regenerate dense stands of root sprouts (suckers) is well documented (Brinkman and Roe 1975). Tens of thousands of suckers per hectare are commonly produced when stands are killed by fire or removed by clearcutting.

Ecological Aspects Of Air Pollution From An Iron Sintering Plant At Wawa, Ontario, A.G. Gordon, E. Gorham
Ecological Aspects Of Air Pollution From An Iron Sintering Plant At Wawa, Ontario, A.G. Gordon, E. Gorham
Aspen Bibliography
At Wawa, in northern Ontario, vegetation has been damaged severely by sulphur dioxide pollution from an iron-sintering plant. Damage is mainly restricted to a narrow strip northeast from the sinter plant, since southwest winds are strongly predominant. It is traceable from the air for at least 20 mile in this direction and is estimated as severe within 11 miles and very severe within 5 miles. Within about 10 miles NE, from the sinter plant ground flora variety declines markedly, from about 20-40 species per 40 square meter quadrat beyond this distance to 0-1 species within 2 miles of the pollution …
Some Aspects Of The Aspen-Birch-Spruce-Fir Type In Ontario, D.W. Maclean
Some Aspects Of The Aspen-Birch-Spruce-Fir Type In Ontario, D.W. Maclean
Aspen Bibliography
The mixedwood types of the Boreal Forest in Ontario occupy sites that have a high potential for the production of spruce and fir. These types are commonly made up of various mixtures of trembling aspen, white birch, black spruce, white spruce, and balsam fir2. In the unmanaged forest, this mixture of species usually results from fire, and the coniferous component is largely spruce. In the managed forest, fir rather than spruce is likely to be the main coniferous species in the next crop where measures are not employed to alter this trend in succession. This is a matter …
Regenerating Aspen By Suckering In The Southwest, Merylyn M. Larson
Regenerating Aspen By Suckering In The Southwest, Merylyn M. Larson
Aspen Bibliography
Although seeding is necessary for the spread of aspen into new localities, suckering (sprouting from adventitious buds on the roots) is the chief means of reproduction in established stands. Suckering can usually be induced by reducing or eliminating the aspen overstory. 2
Possibilities Of Managing Aspen, Paul Zehngraff
Possibilities Of Managing Aspen, Paul Zehngraff
Aspen Bibliography
The management of aspen or popple (Populus tremuloides) has received little attention in the past, largely because of the former abundant supply of other and more valuable tree species in the Lake States. Be- cause of a rapidly expanding market for all forest products during the past decade, particularly during the war, the attention and ingenuity of industry have turned toward the use of aspen. As a consequence, aspen has now become one of the important pulpwood species in the Lake States, and is used for many other products. That it will retain its place for some time to come …

Some Effects Of Cover Over Coniferous Seedbeds In Southern New England, James W. Toumey, Ernest J. Neethling
Some Effects Of Cover Over Coniferous Seedbeds In Southern New England, James W. Toumey, Ernest J. Neethling
Yale School of the Environment Bulletin Series
The object of the study as at first conceived was to secure experimental data under the climatic conditions of southern Connecticut: 1. On the effect of shade as compared with full light on the time required for germination, and on germination values in representative conifers, and on survival and growth during the first season. 2. On the effect of mulch as compared with exposed soil on the time required for germination, and on germination values in representative conifers, and on survival and growth during the first season.
