Environmental And Successional Relations Of Aspen Communities In Central And Northern Utah, Jan A. Henderson

Aspen Bibliography

Aspen (Populus tremuloides) is a major forest cover type in central and northern Utah. It comprises about 35% of the forest dominated land in this area. It is mostly non-commercial timberland, but has moderately high values for watershed protection, range and wildlife values.

Effect Of Cold Storage On Development Of Suckers On Aspen Root Cuttings, George A. Schier, R.B. Campbell

Aspen Bibliography

The effect of cold storage on suckering ability of excised roots was determined for 10 aspen clones. Root cuttings were collected in June, August, and October and stored for from 7 to 42 days at 2°C. In addition, cuttings from dormant trees were stored for 175 days to determine if they had cold requirements for suckering. Among clones, there were large differences in capacity to produce root suckers. Cold storage had a small but significant effect on the formation and growth of suckers on root cuttings collected in June and August. As a rule, clones responded similarly to cold storage. …

The Extent And Characteristics Of Low Productivity Aspen Areas In Wisconsin, A.L. Lundgren, J.T. Hahn

Aspen Bibliography

The aspen type in Wisconsin occupies about 3.7 million acres, 25 percent of the commercial forest land in the State. Aspen is a major pulpwood species in the State and during recent years has provided 40 to 45 percent of the total pulpwood. Because of the wide extent of the aspen type and importance of the timber industry, there is considerable interest in knowing the inherent capabilities of the aspen forest land.

Spatial Pattern And Population Dynamics Of Populus-Tremuloides In A Saskatchewan Canada Aspen Grove, O.W. Archibold, M.R. Wilson

Aspen Bibliography

The spatial pattern of nine 5-yr age-classes of trees in a grove of Trembling Aspen (Populus tremuloides) was studied by applying nearest-neighbor analysis to a transect.

Biomass And Nutrient Distribution In Aspen, Pine, And Spruce Stands On The Same Soil Type In Minnesota, David H. Alban, Donald A. Perala, Bryce E. Schlaegel

Aspen Bibliography

Vegetation and soils were sampled in adjacent 40-year-old stands of red pine (Pinus resinosa Ait.), jack pine (Pinus banksiana Lamb.), white spruce (Picea glauca (Moench.) Voss), and aspen (Populus tremuloides Michx., P. grandidentata Michx.) on a very fine sandy loam soil in north-central Minnesota. Total tree biomass was greatest for red pine followed by by aspen, spruce, and jack pine. Nutrient weights (N, P, K, Ca, Mg) in the trees were greatest in aspen followed generally by spruce, red pine, and jack pine. Particularly large proportions of biomass and nutrients were found in aspen bark and …

A System For Predicting The Amount Of Phellinus (Fomes) Igniarius Rot In Trembling Aspen Stands, Robert L. Anderson, Arthur L. Schipper, Jr.

Aspen Bibliography

The occurrence of Phellinus (Fomes) igniarius white trunk rot in 45- to 50-year-old trembling aspen stands can be predicted by applying a constant to the stand basal area with P. igniarius rot. Future decay projections can be made by reapplying the basal area of hidden delay for each 6 years projected. This paper describes the methods used to determine the constant and how to use it in the field.

Aspen Sucker Production And Growth From Outplanted Root Cuttings, Donald A. Perala

Aspen Bibliography

Aspen suckers from 1-m-long root cuttings survived and grew better than those from 12.5-cm-long cuttings. Sucker survival and growth were also inversely related to parent root diameter. Discusses the practical implications for aspen management.

Cost Allocation Alternatives For The Senegal River Development Program, J. Paul Riley, Jay C. Andersen, A. Bruce Bishop, David S. Bowles, John E. Keith

Reports

The primary purpose of the study reported herein is to present methods for using estimated project benefits as the basis for distributing the capital, oeprating, maintenance, and replacement costs associated with the proposed Senegal River development program. The problem is complicated because the Senegal River is an international stream, so that it is necessary to consider not only the various economic use sectors involved with the program, but also the three separate countries of Mali, Mauritania, and Senegal. In attempting to meet the primary objective stated above, the report proposes an economic model which estimates economic benefits of the development …

The Great Basin Climate Study For Range Fire Management, Kenneth G. Hubbard, Joel E. Fletcher

Reports

The BLM (Bureau of Land Management) fire management personnel routinely use a fire danger computer program to estimate the effects of recent weather upon the fire hazard on the BLM rangeland sites. The program used for this purpose is the National Fire Danger Rating System (NFDRS) which was developed by the National Forest Service (Deeming, 1978). The NFDRS was used in conjunction with fire weather stations in the Great Basin for the dual purposes of evaluating the ability of NFDRS to predict fire danger and of determining the effectiveness of the present fire station network in detecting fire weather on …
