The waving-wand system of broadcast chemical application implemented in swath widths to 40 ft (>12 m) is capable of simulating broadcast deposition patterns for herbicides similar to those delivered by helicopter. Drop sizes vary from center to edge of swaths, which can range from >1,000 to 5,000 microns (μ). Any...
This case study describes in detail how to conduct a performance review of forest product industries. This case study uses the paper industry for illustration, but the principles and methods presented are such that you will be able to conduct a performance review in any industry.
A detailed cost analysis was performed on 111 U.S. Forest Service campgrounds in the Pacific Northwest (Region 6). Five experience levels were analyzed to estimate facility, operation and maintenance, and opportunity costs. Cost functions, estimated by multiple linear regression analysis to predict the effect of size (number of sites) and...
Tables are presented that summarize 108 published articles on forest growth and yield in the Pacific Northwest. Each table describes the form of the information presented, the species to which the information is applicable, the data sources used to develop the information, the data needed to predict growth and yield,...
Summaries from 49 published articles on site-index and dominant-height growth curves and equations are presented for 20 tree species or species groups found in California, Oregon, Washington, British Columbia, southeastern Alaska, Idaho, and western Montana. The summaries are organized by species. Each summary describes the modeling approach, type of curves/equations,...
Summaries from 49 published articles on tree volume and taper equations are presented for 39 tree species found in California, Oregon, Washington, British Columbia, southeast Alaska, Idaho, and western Montana. The summaries are organized by species and then by type of equation (volume or taper). Each summary describes the types...
This Practical Guide is a companion to the video program Communication Strategies for Fire Management: Creating Effective Citizen-Agency Partnerships. The video is designed to assist land management personnel in working collaboratively with citizens for community fi re and fuel reduction strategies. The DVD uses real world examples from successful agency...
This study was initiated and designed, first, to determine the reliability of the stocking survey system, and, second, to construct free hand curves which would give the ratio of percent of stocking to number of trees per acre.
This monograph describes the concept of allocating aggregate costs of logs, wood, and manufacturing to specific products based on those products' relative market values. It includes results of a survey and a general analysis of the issues involved.
A technique for solving efficiently the catenary problem encountered in surveying with tapes is presented. The theory of the catenary solution is outlined, and our technique is shown to solve correctly the catenary for all conditions. Analysis of error that compared the catenary correction to the more commonly used parabolic...
Aerial photo cruising that can be accomplished quickly, cheaply and with a satisfactory degree of accuracy has been the goal of many forest mensurationists throughout the world. As early as 1925, photo cruising was accomplished successfully by Professor R. Hugershoff and his associates in Germany. The development of this technique...
This annotated bibliography is a response to widespread interest in stream habitat improvement in the Pacific Northwest by land managers, governmental and nongovernmental organizations, and the lay public. Several guides to stream habitat improvement have been written in the past, but may not be easily accessible to people from diverse...
This pictorial guide is primarily intended to serve as a backdrop for field tours of central Oregon that involve topics surrounding wildland fire. It also is designed to provide an
overview of the role of fire in the major ecosystems characteristic of this region. Topics covered include fire history, fire...
Regression models of height growth and survival were fitted to aggregate data for trees, protected and not protected from animal damage, that had been surveyed on Douglas-fir and ponderosa pine plantations in Oregon and Washington. Animal damage significantly affected both height and survival. Dynamic programming analysis-using both soil expectation (Se)...
Mammal and bird damage recorded on Douglas-fir and ponderosa pine plots-randomly established in Oregon and Washington during 1963-64, then observed for 5 to 10 years-was evaluated for impact on survival and growth. In all, 194 plots were installed, and 10 of the 110 seedlings on each plot were caged to...
This bibliography lists selected references useful to the forester in managing young forests in the Douglas-fir region. The references pertain to those management activities that are carried on in the forest from stand regeneration until final harvest. Emphasis is on silvicultural, operational, and economic aspects of management, but social and...
