Learning about people’s views on nature and their attitudes towards national parks is important for the sustainable development and success of national parks. However, the relationship between these two topics is a relatively under-researched area. This study sets out to investigate this relationship for visitors of Harz National Park, Germany. Visitors’ views on nature, conservation measures in the national park and the relationship between those are analysed through data that was collected with an online survey during a period of two weeks in March 2022. Respondents favour a concept of human-nature interdependence but sometimes contradict themselves concerning the place of humans in nature. Harz National Park and conservation measures are accepted by respondents. Results show that knowledge about the importance of bark beetles is an area in which the national park can improve its information campaigns. A small to moderate but statistically significant relationship exists between views on nature and attitudes on conservation measures. This provides a basis for future continued research of Harz National Park, as well as in different contexts.

In 1916 the United States National Park Service (NPS) was founded to conserve the nation’s natural and cultural landscapes as well as “to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.” While much historical analysis has been done by historians and the NPS on the agency’s national history, these scholars have ignored how the NPS was shaped by and contributed to an international history of national parks. Thus, this thesis addresses this historiographical gap and institutional forgetfulness by examining the agency’s Division of International Affairs (DIA). The DIA was established in 1961 by the NPS to foster international cooperation by building national parks overseas, which often advanced foreign policy containment initiatives in the developing world during the Cold War. Following the end of the Cold War, a significant decline in activity and staffing made it more difficult for the DIA to return to the pull of its influence just a decade or two earlier. In 1987 the DIA was renamed the Office of International Affairs (OIA) and has since suffered from many of its parent agency’s larger issues including a decline in staffing, funding, and a host of other issues that have compromised the NPS’s ability to meet its mission. As the NPS celebrates its centennial in 2016, I argue that examining the NPS’s history of international work challenges the agency to consider its past in new ways in the hopes that it reconfigure its mission and future to best meet the needs of its audiences in a globally connected twenty-first century world. / History

The effects of gypsy moth infestation on the Shenandoah National Park (SNP) black bear population and habitat were studied during 1985 - 1991 by comparing radio telemetry, population, and behavioral data from preinfestation years (1982 - 1986) and years with extensive defoliation (1987 - 1991). Gypsy moth defoliation (> 60% canopy loss) increased from 546 ha in 1986 (1 % of the study area), to 2,304 ha in 1987 (4%), 6,227 ha in 1988 (12%), and 17,736 ha in 1989 (34%). Chestnut oak and red oak habitat types received the greatest defoliation; 60% and 45% of these habitat types suffered greater than 60 % canopy loss in the North and Central Districts, respectively. Infestation resulted in a 99% reduction in acorn production in defoliated stands. Maximum daily temperatures 0.5 m above the ground in defoliated stands averaged 4.7 ± 0.3 C, 4.3 ± 0.4 C, and 2.5 ± 0.3 C warmer (P < 0.01) than in nondefoliated stands during peak defoliation, refoliation, and post-refoliation periods, respectively.

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

During the last decades ecology and behaviour have become of major importance in African ornithology. Not only have more individual species been studied in detail, but behaviour and ecology have been used in a more general sense in regional works (Benson et al 1971} and in zoogeographical treatises (Moreau 1966, Hall and Moreau 1970). As part of a world- wide trend, behaviour and ecology have also become important in systematics and taxonomy eg. Hall's 1963 study of francolin, and Benson et al's 1971 erection of the bush shrike family Malaconotidae. This dissertation fits into this trend, beginning with a detailed study of the ecology and behaviour of three species of hornbill of the genus Tockus, and extending the observations in less detail to five other members of the genus. Combined with the literature, these observations allow an analysis of the systematics and evolution of the genus Tokus to be undertaken, as well as supplying descriptive information on Tokus biology.

KwaZulu-Natal’s Hluhluwe-Imfolozi Park has historically been prioritized for biodiversity conservation but it also has the oldest protected wilderness area in the country. For 50 years, conservation management, tourism and education within the Imfolozi Wilderness Area have generally been carried out using non-mechanized wilderness principles. The validity of the Imfolozi Wilderness is constantly questioned in terms of efficiency, equity and aesthetics and is consequently subject to a variety of pressures that those different ideologies can exert. The historical development and applicability of the wilderness concept is examined here against evolving South African social and environmental circumstances. Whilst this investigation confirms the findings that colonialism and apartheid resulted in the exclusion of local peoples from protected areas, it also takes note that Imfolozi’s history is characterized by organizations and individuals who ignored the racist laws of the time. Nevertheless, management structures pertaining to both politics and conservation tended to be top-down, such that the Imfolozi Wilderness retained an air of elitism, regardless of attempts to be racially inclusive. Modern trends in protected area management expose the necessity of refining the justification of wilderness areas, to simultaneously recognize localized priorities and the importance of such areas to the planet’s ecological wellbeing. Without attempting to resolve philosophical debates but, at the same time, recognizing their validity, protected area management requirements for the Imfolozi Wilderness are examined in terms of the legal mandate handed to the management agency. This leads to the selection of the Limits of Acceptable Change planning and management system which is implemented as an action research project in conjunction with the Imfolozi Management Team, over a three year period. This involved: defining legal mandates and area issues; defining the zonation categories for the wilderness area; selecting the indicators to measure human impact; compiling an inventory of conditions in the wilderness area; specifying standards; examining alternative zonation category allocations from stakeholders and selecting a preferred alternative. The desired outcome was the establishment of a system in which managers could receive ongoing collaboration from stakeholders and consultatively develop a defendable wilderness management strategy that would meet the legal requirements of the area’s proclamation. Through a descriptive narrative, this dissertation provides an account of the implementation process and discusses to what extent this has been achieved. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2009.
