The Forest Inventory Mapmaker Web application (https://www.nrs.fs.usda.gov/4801/fiadb/) provides users with the ability to easily generate tables and shaded maps. The goal of this manual is to present the basic concepts of the Web application to the user and to reinforce these concepts through the use of tutorials.

Discusses recent Kansas forest industry trends; reports production and receipts of industrial roundwood by product, species, and county in 1998. Also reports on logging residue, on wood and bark residue generated at primary wood-using mills, and on disposition of mill residues.

A follow-up survey of residents in southeastern Minnesota shows that environmental values were stable over a 5-year period. The authors were unable to measure any impacts of a Minnesota Department of Natural Resources comprehensive watershed planning initiative in the Wells Creek watershed on residents' behaviors and attitudes and perceptions about the environment.

A study of outdoor recreation preferences and behavior of Non-Hispanic White Americans (n=618), African Americans (n=647), and Hispanic Americans (n=346) in Cook County, Illinois was conducted in early 1999. Respondents were contacted in a phone survey using random digit dialing and a quota for each group. Important similarities and differences were found among these three groups in their participation in 43 activities and use of 20 places. In addition, gender, age, education, income, residence, and household size helped explain outdoor recreation preferences and behavior. Results reported...

This study was conducted as part of a larger multi-community needs assessment. Data from this study allows for the determination of support for a multiple-use trail system linking communities within the Soucook River Watershed Region in New Hampshire. This study also examines the relationship between support for trail development and community attachment. The results provide evidence that the level and direction of support for trail development depends on the measures that are used to determine such support, highlighting the need for continued research regarding appropriate measures of...

As the sport of mountain biking has grown in popularity, many localities have begun to develop facilities and promote cycling based tourism. Unfortunately, these promotional efforts often occur with little knowledge of the characteristics and preferences of mountain bikers. This study was an initial effort to collect descriptive data on the riding, travel and spending behavior of mountain bicyclists in the Central Appalachian region.

The lymantriid forest defoliators, Lymantria monacha L. (nun moth) and Lymantria dispar L. (gypsy moth) are particularly severe pests in other countries in the world, but the ability of these moths to utilise and complete development on Pinus radiata D. Don had never been established. In laboratory trials, colonies of central European L. monacha and Russian far east (flight capable) L. dispar were fed on foliage from three mature P. radiata trees originating from three different advanced-selection families from New Zealand. The results showed that both moths were capable of completing...

In the laboratory, the timing of both preflight and flight behaviors of the Asian strain of female gypsy moths, Lymantria dispar L., was regulated primarily by light intensity. The shortest times to initiation of wing fanning and flight occurred at 0.1 lux, the lowest light intensity evaluated. A gradual decrease in light intensity, compared with an instantaneous decrease, prolonged time to flight. The highest percentage of female flight was observed at 0.1 lux. A higher percentage of females initiated flight when exposed to lower light intensities after the onset of normal scotophase...

Effective and maximum value use of small-diameter hardwood timber has long been of interest to forest managers and researchers. In addition to being a significant component of the standing forest base, small-diameter hardwoods often are available after thinning or other tending operations. Although the use of this material is important to achieving healthy and sustainable forests and other ecosystem management objectives, finding economical uses is sometimes difficult. Much prior research has addressed small-diameter hardwood utilization. After discussing some forest statistics concerning...

The eastern hardwood resource contains numerous species that differ in grain, color, texture, and workability. Because the value of hardwoods is derived from appearance, these variations in physical attributes can cause the price for identical grades of hardwood lumber to vary by as much as 600% between species. As a result, there is incentive for primary processors to harvest certain species more intensively than others, which could affect long-term forest composition. This article introduces the concept of relative utilization to augment the infrequently published annualized growth-to-dra...
