Attitude surveys can serve as a basis of public interest and opinion inputs to National Park Service planning and management decision making. The initial objective of this study was to develop a method for scaling attitudes which alleviated problems of interpreting effects of two related components of attitude--beliefs and corresponding evaluations of those beliefs. In conjunction with this objective, visitor knowledge about and attitudes toward resource use and management in Shenandoah National Park were assessed. Finally, guidelines were formulated suggesting how to design an effective interpretive message taking into account relevant user characteristics, level of knowledge, and attitudes toward resource use and management in the national park. Considering summer months and weekend/weekday visitation patterns, a stratified random sample of days was selected to contact park visitors. On designated sampling days visitors were contacted at lodges, backcountry stations or campgrounds. Names and addresses were secured via an information release form. In September, 1978, individuals were mailed an attitude survey. A follow-up post card and two selective follow-up questionnaire mailings ensued. Overall response rate was 81 percent. The survey instrument obtained contributions of belief and affective components of attitude. In order to measure these components in a manner reflecting resource management objectives and allowing easy interpretation of attitude scores, a new modified matrix scaling technique was developed. A matrix of attitude scores was computed using an unipolar belief scale and bipolar affect scale. The computed using an unipolar belief scale and bipolar affect scale. The belief scale was also employed to determine visitor level of knowledge concerning resource use and management in Shenandoah National Park. The over-all matrix system was developed within the framework of Fishbein's (1963) expectancy value attitude theory. The scaling method lessened some of the problems created by using standard bipolar st.nnmative scaling. In addition, final scores derived from this matrix procedure were logically consistent, theoretically appropriate, and may be managerially relevant. Results of analyses of variance in overall belief and attitude scores suggested the utility of developing different interpretive messages about resource use and management for the three camping styleslodge, campground, and backcountry users. Attitude changes predicted via the expectancy value formulation indicated the importance of considering the distribution of visitor attitude scores before attempting development of an interpretive message designed to influence attitudes. / Ph.

The seasonal movements, food habits, and habitat selection of black bears (<i>Ursus americanus</i>) in Shenandoah National Park, Virginia were studied from May 1982 to April 1985. A total of 47 collared bears, including 25 adult females, 17 adult males, and 5 subadult males < 3.5 years old, was located 3973 times during the study. Adult males had larger (<i>P</i><0.001) home ranges (100% X=195 km², 95% X=116 km²) than adult females (100% X=38 km², 95% X=22 km²). Subadult males had larger (<i>P</i><0.10) home ranges (100% X=542 km², 95% X=289 km²) than adult males and females. Extensive home range overlap occurred among each sex and age group. At least three subadult males dispersed from the Park during the study. Female bears with cubs were less mobile than solitary females during the spring. Fall cubs were large and did not restrict females' movements. Large fall home ranges for females were related to the scattered supply of acorns relative to the concentrated sources of soft mast used in the summer. Two females with cubs and 2 subadult males remained active during the winter months. Adult and subadult males generally had less stable home ranges than adult females. Female bears displayed infidelity to given areas during the fall from year-to-year due to variation in the distribution of hard mast (acorns). Male bears made long excursions onto the Piedmont Plateau east of the Park mainly during the spring and early fall. Females were not exposed to as much human induced mortality as males because they were located within the Park 17% more frequently than males. Males avoided fire roads (<i>P</i><0.001), light duty roads (<i>P</i><0.001), and primary roads (<i>P</i><0.01) year around. Female bears preferred fire roads during summer (<i>P</i>< 0.001) and early fall (<i>P</i><0.01) and avoided heavier traveled roads such as light duty roads (<i>P</i><0.001) and primary roads (<i>P</i><0.001) year around. Both male and female bears preferred foot trails for travel (<i>P</i><0.05). Bears rarely came within 100 meters of campgrounds, picnic areas, and other human disturbance areas within the Park. Both sexes used low (<i>P</i><0.10) elevations during the summer and high (<i>P</i><0.10) elevations during early and late fall. Bears showed the greatest use of small rivers and streams during the driest months of summer. Geographic land forms of specific aspects, contours, and varying steepness were used differently by male and female bears. Twelve stomachs and 854 scats were analyzed for food content. Forbs, graminoids, squawroot (<i>Conopholis americana</i>), corn, and the fruits of trees, shrubs, and vines composed 90 percent volume of the annual diet. Eight percent of the food consumed was animal matter from mammals, birds, and invertebrates. During all seasons, females used yellow poplar (<i>Liriodendron tulipifera</i>) forests more (<i>P</i><0.05) than males while males used yellow poplar forests less (<i>P</i><0.05) than expected; males used black locust (<i>Robinia pseudoacacia</i>) \ black cherry (<i>Prunus serotina</i>) forests more (<i>P</i><0.05) than females and more (<i>P</i><0.05) than expected. Shifts in use of chestnut oak (<i>Quercus prinus</i>) \ northern red oak (<i>Q. rubra</i>) forests and northern red oak \ white oak (<i>Q. alba</i>) forests by both males and females in early and late fall was attributed to annual variation in oak mast production, preference for white oak acorns, foraging strategy, and the importance of mountain laurel (<i>Kalmia latifolia</i>) shrub cover in late fall. Seasonal use of domestic fruits at 330 abandoned homesites was determined. Distance-to-nearest-homesite measurements indicated that males were never closer (<i>P</i>>0.10) to homesites than females or random points during any season while females were closer (<i>P</i><0.001) to homesites than males and random points during summer. Only females were located at homesites (≤ 100m) more (<i>P</i><0.001) than expected during summer and early fall. Bears consumed apples (<i>Malus</i> spp.) and sweet cherries (<i>Prunus avium</i>) at abandoned homesites mainly in summer, early fall, and late fall. Bears used homesites in late fall more than distance measures indicated. Domestic fruits were an important nutritional food for black bears in relation to total soft fruits eaten. / Master of Science / incomplete_metadata
