Preliminary Analysis Of The Management Situation Summary, Wasatch-Cache National Forest, April 1999, United States Department Of Agriculture, Forest Service
Forestry
The National Forest Management Act (NFMA) of 1976 (NFMA P.L. 94-588) required each National Forest to develop National Forest Land and Resource Management Plans (Forest Plans), and to update or "revise" them when conditions have significantly changed or at least every 15 years. The Wasatch-Cache National Forest completed its current Forest Plan in 1985 (USDA Forest Service 1985). To comply with NFMA a revision needs to be completed by the end of 2000. In 1997, Congress prohibited expenditure of funds on formal Forest Plan revision. In 1998 prohibitions were lifted for 14 national forests nationwide. The Wasatch-Cache National Forest was …

First Order Fire Effects Model: Fofem 4.0, User's Guide, United States Department Of Agriculture, Forest Service
Forestry
A First Order Fire Effects Model (FOFEM) was developed to predict the direct consequences of prescribed fire and wildfire. FOFEM computes duff and woody fuel consumption, smoke production, and fire-caused tree mortality for most forest and rangeland types in the United States. The model is available as a computer program for PC or Data General computer.

Forestry
This guide provides technical descriptions of 23 Intermountain rushes (Juncus spp.), including the common and several less abundant species. Line drawings and color or black and white photos illustrate diagnostic characteristics of each species. An illustrated morphology and a glossary acquaint the layperson with terminology used to classify rushes. The guide is intended as a tool to aid in classification; it is not inclusive.
Ecology And Management Of Larix Forests: A Look Ahead ... Proceedings Of An International Symposium, United States Department Of Agriculture, Forest Service
Ecology And Management Of Larix Forests: A Look Ahead ... Proceedings Of An International Symposium, United States Department Of Agriculture, Forest Service
Forestry
This proceedings is the product of an international symposium on the Larix species of North America, Europe, and Asia. Western larch, an important species in the Western United States and Canada, was featured. The symposium included information on ecology, management, silviculture, regeneration processes, growth, wildlife, vegetation succession, silvics, history, genetics, breeding and provenance testing, physiology, fire, insects and disease, and research need. This proceedings illustrates the importance of Larix in the temperate forests of the Northern Hemisphere.
Uneven-Aged Forest Management: State Of The Art (Or Science?)
Uneven-Aged Forest Management: State Of The Art (Or Science?)
Forestry
Examines some important historical factors that have caused widespread preference of the even-aged management system over the uneven-aged. Major decisions facing forest managers interested in applying uneven-aged management are defined, and a review is made of techniques traditionally used, or recently proposed, for use in making these decisions. Finally, problem areas needing further research and development are identified.

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.
