Aspen Bibliography
Biomass prediction equations were developed for 23 northeastern Minnesota shrub species. The allometric function was used to predict leaf, current annual woody twig, stem, and total woody biomass (dry grams), using stem diameter class estimated to the nearest 0.25 cm class at 15 cm above ground level as the independent variable.

Forest Insect And Disease Management : Aspen Mortality At The Maroon Lake Campground, David W. Johnson, Thomas E. Hinds
Aspen Bibliography
At the request of the White River National Forest, Dave Johnson, Plant Pathologist, FI&DM and Tom Hinds, Plant Pathologist, RMFRES, made an evaluation of aspen mortality in the Maroon Lake Campground, Aspen Ranger District during June 13 to 15, 1977. Previously, Hinds (1976) reported accelerated aspen loss in 17 campgrounds, including Maroon Lake, located throughout Colorado and New Mexico (Fig. 1).

Aspen Forest After Harvest, Norbert V. Debyle
Aspen Forest After Harvest, Norbert V. Debyle
Aspen Bibliography
Aspen is a unique forest tree with respect to regeneration. It produces abundant root suckers, up to 40,000 per acre are common, after clearcutting or fire removes the parent stand. The rapidly growing sucker stand competes well with other vegetation, but is susceptible to destruction by excessive ungulate browsing. Clearcut areas produce more streamflow and more growth on shrubs and herbaceous vegetation than does the uncut forest. The patchwork of age classes that results from even-age management optimizes wildlife habitat requirements for several desired species.

Location-Allocation Models For Establishing Facilities, David F. Gibson, John Rodenberg
Location-Allocation Models For Establishing Facilities, David F. Gibson, John Rodenberg
Aspen Bibliography
Two models and accompanying computer programs are presented which were developed to locate facilities for the timber harvesting industry. Addressed is a case of the facility location-allocation problem. The optimum location and number of landings, facilities to which timber is transshipped, are determined so as to minimize a cost function. This function is composed of the following components: (1) cost of transporting material from its original location to a landing, (2) cost of establishing a landing (facility cost), and (3) cost of transporting material from the landings to some designated point termed the origin. Output of the computer programs is …

Yields From 18-Year-Old Aspen Via Total Tree Harvesting, M. K. Benson, D. W. Einspahr
Yields From 18-Year-Old Aspen Via Total Tree Harvesting, M. K. Benson, D. W. Einspahr
Aspen Bibliography
Described are the results of harvesting the above-ground parts of an 18-year-old aspen stand and the observations made on the initial suckering of the new stand. The yields for the stand of 17.7 cunits per acre were greater than predicted yields of comparable material for the site at age 35. Suckering on the area the first year after cutting averaged 37,000 aspen stands per acre and 2.6 feet in height.

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.
