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 …

Fire Frequency And The Vegetal Mosaic Of The Utah State University Experimental Forest, Linda L. Wadleigh-Anhold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A fire history study conducted for the Utah State University (USU) Experimental Forest using three distinct periods of fire frequency, historic (1700-1855), settlement (1856-1909), and suppression (1910-present), showed a decreased mean fire interval (MFI) during the settlement period and a greatly increased MFI during the suppression era. The difference was attributed to the influx of ignition sources during the settlement of the nearby Cache Valley, located 40 kilometers to the west. The interaction of settlers with the resource during logging and livestock grazing activities encouraged the high MFI and created the vegetal mosaic now observed on the study area.

Southern Pine Beetle And Fire In Wilderness Areas: The Kisatchie Hills Wilderness, Kisatchie National Forest, David Kulhavy, William G. Ross

Faculty Publications

Southern pine beetle infestations affect wilderness areas in the southeastern United States. In the Kisatchie Hills Wilderness area in Louisiana, a southern pine 'beetle outbreak resulted in widespread destruction of longleaf pine. Nest trees of the red-cockaded woodpecker, an endangered species, also were killed. Following the epidemic, a fire fueled by beetle-killed pines went through the wilderness. Forest structure, species composition, successional processes and general ecosystem function were substantially altered as a result of these two related disturbances. Most wilderness areas containing southern pines were managed for pine timber before being designated as wilderness. Bark beetle outbreaks are a predictable …

Manually Calculating Fire-Danger Ratings - 1978 National Fire-Danger Rating System, United States Department Of Agriculture, Forest Service

Forestry

This publication contains instructions for manually calculating the indexes and components of the 1978 National Fire-Danger Rating System (NFDRS). The procedures are explained with worked examples. Working sets of nomograms for the 20 NFDRS fuel models are not included. However, an order form for obtaining the needed nomograms is provided. USDA Forest Service General Technical Report INT-39, The National Fire-Danger Rating System--1978 by John E. Deeming, Robert E. Burgan, and Jack D. Cohen, a companion publication, covers the NFDRS background, applications, and general principles of the system.

Deterioration Of Aspen Clones In The Middle Rocky Mountains, George A. Schier

Aspen Bibliography

The frequent failure of deteriorating aspen (Populus tremuloides Michx.) clones to regenerate vegetatively by root suckers was studied by comparing the suckering capacity of these clones with adjacent healthy clones. Sucker production from root cuttings was used to evaluate the suckering capacity of a clone. Scarcity of regeneration in deteriorating clones was found to be unrelated to the ability of roots to sucker. A hypothesis based on the apical dominance phenomenon is presented to account for the low numbers of suckers produced by deteriorating clones. Stand data, sucker densities, and root ages of the clones are compared. Aspects of aspen …
