The New York State Office of Parks, Recreation, and Historic Preservation has had a land classification system in place since 1972. This system was developed during the creation of the first Statewide Comprehensive Outdoor Recreation Plan. This system has become the backbone of the Park Master Planning Process. During the past few years the New York State Park System has undergone serious evaluation. This evaluation determined that the Parkland Classification System is out of date and no longer addresses today's need or issues. This paper attempts to illustrate how the New York State...

This study gathered information about mountain bike use and users on unpaved trails in a Raleigh, North Carolina park. Specifically, it attempted to determine if levels of recreation specialization were related to the setting preferences of mountain bike users. The results offered partial support for the existence of a relationship between recreation specialization and preferences for various setting attributes.

The long era of "protection of natural resources through acquisition" is gradually drawing to a close. The budget-busting era of "protection through management" is forcing us to look for new funding mechanisms. But the idea of facilitating protection through enlightened self-interest is ripe for growth. Resource interpreters can provide the link with visitors and other constituents to influence "resource protective" behavior and develop a land ethic.

Outdoor recreation resources are eroding in Vermont's Lake Champlain Basin due to urban expansion. This study measured urban growth in the Basin and identified critical areas for open space protection. The study's hypothesis, that there was no difference between the Champlain Basin and other parts of urbanizing New England that have lost outdoor recreation resources, was accepted.

Planning regulations pursuant to the National Forest Management Act of 1976 require the USDA Forest Service to produce cost-effective, multiple-use forest plans that ensure the viability of native wildlife populations within the planning area. In accordance with these regulations, this paper presents a method for determining cost-effective conservation plans for sensitive wildlife species. The method is a decision framework for determining what forest areas should be managed as habitat to meet a population viability constraint and what areas should be used for timber production to maximize...

The entomocidal CryIIIA δ-endotoxin protein of Bacillus thuringiensis var. tenebrionis is distinctive in chemistry and host range. In contrast to other δ-endotoxins, the CryIIIA parasporal crystals are toxic within the acidic midgut environment of several coleopteran species, particularly those in the family Chrysomelidae. Resistance to this toxin was successfully developed by laboratory selection of Leptinotarsa decemlineata (Whalon et al., 1993) and Chrysomela scripta (L. S. Bauer, D. L. Miller, and C. N. Koller, unpublished). Our investigations of the B. thuringiensis var. tenebrionis...

In 1991, late instars of gypsy moth, Lymantria dispar (L.), were sampled and diagnosed for infections of the pathogenic fungus Entomophaga maimaiga Humber, Shimazu & Soper and for gypsy moth nuclear polyhedrosis virus (NPV) at 50 sites in Michigan. Approximately 1,500 larvae were collected and reared from these sites, and no infections of E. maimaiga were detected. From 1991 to 1993, we tested the efficacy of 2 inoculative-release methods for E. maimaiga in replicated plots at 3 research sites by relocating soil containing E. maimaiga resting spores from Massachusetts to Michigan or by...

Insecticidal crystal proteins (also known as d-endotoxins) synthesized by the bacterium Bacillus thuringiensis Berliner (Bt) are the active ingredient of various environmentally friendly insecticides that are 1) highly compatible with natural enemies and other nontarget organisms due to narrow host specificity, 2) harmless to vertebrates, 3) biodegradable in the environment, and 4) highly amenable to genetic engineering. The use of transgenic plants expressing Bt d-endotoxins has the potential to greatly reduce the environmental and health costs associated with the use of conventional...

Public concern over the adverse visual impact of clearcutting has heightened interest in developing and testing alternative regeneration practices for central Appalachian hardwoods. Group selection can meet aesthetic goals while providing suitable light conditions to reproduce shade-intolerant species. Volume control and residual stand density are used to regulate periodic cuts. In central Appalachian hardwoods, openings must have a minimum size of 0.4 acre; all stems 1.0 inch d.b.h. and larger are cut to reproduce desirable shade-intolerant species. Openings should be located using the...

In-stream recreation use of the upper Pemigewasset and Swift River Drainages was estimated by a technique based on modified, stratified sampling. Results are reported by category of stream segment, season, day of week, time of day, and activity. "Weekend and holiday" use exceeded weekday use during spring and fall, but weekdays had the heaviest use during the summer. Recreation use was much greater in summer than in spring or fall.
