Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers
Pando's Pulse: Vital Signs Signal Need For Course Correction At World-Renowned Aspen Forest, Paul C. Rogers
Aspen Bibliography
Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. As aspen ecosystems flourish or diminish, myriad dependent species follow suit. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers that are nutritiously desirable to browsing ungulates. Here, I evaluate aspen reproduction alongside numerous vital indicators of Pando's status in the first trend assessment of this embattled iconic forest. …
Gibsonville Healthy Forest Restoration Project: Silviculture Report, Dan Roskopf
Gibsonville Healthy Forest Restoration Project: Silviculture Report, Dan Roskopf
Aspen Bibliography
The Forest Service proposes to reduce the risk of wildfire, to protect, restore, and enhance forest ecosystem components (i.e., streams, meadows, aspen areas) in the vicinity of Gibsonville, California. A combination of hazard tree removal, forest health, and fuels reduction treatments are proposed on 1,200 acres of Forest Service system lands. These actions are proposed to be implemented on the Feather River Ranger District of the Plumas National Forest.

Forage Quality In Burned And Unburned Aspen Communities, N.V. Debyle, P.J. Urness, D.L. Blank
Forage Quality In Burned And Unburned Aspen Communities, N.V. Debyle, P.J. Urness, D.L. Blank
Aspen Bibliography
We assessed the effects of fire on the quality of herbaceous and browse forage for elk (Gervus e/aphus) and domestic sheep in the aspen (Populus tremu/oides) forest type. Selected forage species were sampled on burned and adjacent unburned areas during the summers of the first and second years after autumn prescribed burning of three sites in southeastern Idaho. These samples were analyzed for in vitro dry matter digestibility (IVDMD), crude protein, calcium, and phosphorus. This aspen type has a highly nutritious understory irrespective of burning. We found additional improvement in forage quality as a result of prescribed burning. In the …
Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch
Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch
Aspen Bibliography
Numbers of breeding birds were estimated for various sizes and ages of clearcuts, for edge habitat created by the clearcuts, leave strips between clearcuts, and uncut aspen forest (controls). Total numbers of birds were not different among three size classes or five age classes of clearcuts. Total were lower on clearcuts than on edges but not different from controls or leave strips.

Response Of Breeding Birds To Commercial Clearcutting Of Aspen In Southwestern Colorado [Usa], V.E. Scott, G.L. Crouch
Response Of Breeding Birds To Commercial Clearcutting Of Aspen In Southwestern Colorado [Usa], V.E. Scott, G.L. Crouch
Aspen Bibliography
Breeding birds on an aspen forest in southwestern Colorado increased in species diversity after 25% of the timber sale area forest was clearcut in patches of 3 to 20 acres. Bird population density on the forest with clearcuts was not significantly different from that on an uncut forest. Of the 20 species evaluated, six were more and one was less abundant than on the uncut forest.

Preliminary Fresh And Dry Weight Tables For Seven Tree Species In Maine, Harold E. Young, Lars Strand, Russell Altenberger
Preliminary Fresh And Dry Weight Tables For Seven Tree Species In Maine, Harold E. Young, Lars Strand, Russell Altenberger
Aspen Bibliography
Long range forecasts of the use of wood, independently prepared by the Forestry and Forest Products Division of the Food and Agriculture Organization in Rome and the Standard Research Institute in California, concluded that in the foreseeable future there will be only a slight increase in the consumption of lumber but a rapidly increasing use of products made from wood fiber such as paper and paperboard.
Since 1955 the use of weight as a basic unit of measurement for roundwood and chips has increased more rapidly than the consumption of products made from such material. In some portions of the …
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 …

The Growth And Yield Of Aspen [Populus Tremuloides] In Saskatchewan, C. L. Kirby, W. S. Bailey, J. G. Gilmour
The Growth And Yield Of Aspen [Populus Tremuloides] In Saskatchewan, C. L. Kirby, W. S. Bailey, J. G. Gilmour
Aspen Bibliography
This report is a summary of all studies carried out by the Saskatchewan Forestry Branch in hardwood stands. Aspen, the principal component of the hardwood stands, is the most abundant tree species by both volume and area in Saskatchewan and is most difficult to analyze. This report presents conclusions from which further studies can be conducted. It is hoped that in the future closer correlation with site-types may be made as it is difficult and probably not desirable to make further generalization on a province-wide basis. However, before detailed questions could be studies it was necessary to have a picture …

The Treatment Of Decayed Wood From Dead Trembling Aspen Trees For Growth-Ring Analysis, Arthur W. Ghent
The Treatment Of Decayed Wood From Dead Trembling Aspen Trees For Growth-Ring Analysis, Arthur W. Ghent
Aspen Bibliography
This paper elaborates certain procedures briefly outlined in an earlier article. Although dry wood from dead trembling aspen has been found best suited to growth-ring analysis, in its absence use has been made of water-saturated wood from the underside of fallen trunks. A technique of wax impregnation, adaptable to wood in both early and advanced stages of decay, is described. Rapid impregnation with near-boiling wax is sufficient to facilitate transverse sectioning of relatively sound wood; advanced decays require a slower impregnation with cooler paraffin. Hot xylol is used to remove the wax and flatten the section. Successive, overlapped sections provide …
