Managing bog environments for recreational experiences

Bogs are of interest to outdoor recreationists, but little information exists concerning how recreation resource managers might manage these areas to enhance visitor benefits. This study evaluates bog visitor characteristics and experiences, visual preferences, and reasons for visiting. Implications for recreational resource management of bogs include the location and design of boardwalk trails and management of understory vegetation to meet the visual preferences and motives of bog visitors.     

COST OF WASH HOUSES AND COMFORT STATIONS AT RECREATION AREAS1

ABSTRACT: The cost of sanitary facilities is a major cost item in recreation areas at water resources projects. Often planners wish to analyze the tradeoffs in providing different levels of service at these areas. Cost functions are presented in this paper to enable the planner to make quick comparisons between different types of buildings, sizes, exterior treatments, and number of fixtures.     

A BASIS FOR ASSESSING DIFFERENTIAL PARTICIPATION IN WATER-BASED RECREATION1

ABSTRACT: Participation in water-based recreation activities does not arise in random fashion nor simply as a result of having a water resource immediately available. Neither do individuals and groups engage in the same activities or a specific activity in the same way. The purpose of the present paper is to describe an alternative framework whereby differences among recreation users can be identified. Prior to this time, research directed toward understanding participation patterns at a recreational site have emphasized the activities while ignoring the human behavior factors which determine how participation arises. People consider recreation sites to be leisure settings in which the definition of such places has a broader socio-cultural meaning than that the site was designed. These definitions are reflected within the context of the social group and can be observed in the subsequent orientation to leisure and play. When activities are considered in the context of a human group, differences in participation patterns can be discovered.     

Evaluating the acceptability of recreation rationing policies used on rivers

Research shows that users and managers have different perceptions of acceptable policies that ration or limit recreational use on rivers. The acceptability of seven rationing policies was evaluated using Thurstone's method of paired comparisons, which provided a rank ordering of advance reservation, lottery, first-come/first-served, merit, priority for first time users, zoning, and price. Chi-squared tests were used to determine if users and managers have significantly different levels of acceptability for the policies. River users and managers were found to be significantly different according to their evaluation of advance reservation, zoning, and merit. The results also indicated that river users collectively divide the policies into three categories corresponding to high, moderate, and low levels of acceptability, while river managers divide the policies into two levels corresponding to acceptable and unacceptable.     

Floristic contamination of suburban forests near the city of Ivanovo

In the course of floristic studies in suburban forests near the city of Ivanovo, 206 species of vascular plants have been recorded, including 39 invasive species (18.9%). Information on specific features of distribution and activity of introduced species growing feral and accidental weeds in different forest types is presented. The most aggressive species are distinguished. Factors responsible for the invasion of alien species to forest cenoses and main tendencies in their dynamics are discussed.     

SOCIAL CLASS DIFFERENCES IN RESERVOIR VISITS1

ABSTRACT: Previous research provides evidence of a socioeconomic bias in outdoor recreational participation. One explanation of this bias is that socioeconomic groups have differential opportunities to participate, with the “costs” of this participation especially serving to restrict the recreational access of lower class persons living in urban areas. Using driving distance as a measure of cost, this study assessed the effects of travel costs on the attendance of three social class groups from an urban population at rural reservoir facilities. Findings support the contention that, while increased driving distance has a dampening effect on recreational participation, this effect is most pronounced for the lower class person. These findings point to the importance of equity considerations in the planning of outdoor recreational facilities.     

杭州市城市和郊区表土磷库及环境风险评价

杭州市城市和郊区土壤磷素具有明显的积累特征并有较高的潜在释放能力。可提取态P(包括H2O-P、NaHCO3-P.NaOH-P和HCl-P)平均在80％左右，其中以HCl—P的比例最高，平均约55％。32个研究土样中，26个土样的水可溶性(H20—P)在10mg／kg以上，15个土样的NaHCO3—P在100mg/kg以上。酸性条件下P的释放潜力明显增加。土壤水溶性P含量及在酸性条件下P的释放量与土壤总P呈正相关，与土壤pH负相关。     

Review of studies on environmental impacts of recreation and tourism in Australia

The paper provides a review of available information on the impact of recreation and tourism on environments, particularly on vegetation and soil, in Australia, with an emphasis on forests. Efforts have been made to compare the current research and development situation in Australia with some overseas countries such as the United States and the United Kingdom. While many documents reveal that Australia has been experiencing an increasingly high level of recreation and tourism use in its environments, only limited studies of environmental impacts of recreation and tourism have been published. Compared with other developed countries, particularly the United Kingdom and the United States, Australia lags behind in undertaking research in this area. The results of these limited studies and some observations indicate that the most common recreational and tourist activities (such as bush walking, camping, horse-riding) can, if not well managed, adversely affect the values of Australian natural and semi-natural resources. Overall, they can affect the vegetation and other recreational sites physically and biologically. Physical effects include track formation, soil loss and/or compaction and an increase in fire frequency. Littering and water pollution are also seen as impacts associated with bush walking and camping. Biological effects include causing damage to vegetation, increasing risk of myrtle wilt disease and the spread of the soil pathogen,Phytophthora cinnamomi, as well as assisting weed dispersal. Based on the information reviewed, the authors suggest the following areas as priorities for future research into the environmental impact of recreation and tourism in Australia: determine the type of natural features that attract recreation use; determine the quantitative relationship between the impact and the level of recreation and tourism use for different activities within major vegetation habitats; ascertain site carrying capacity or environment thresholds for major vegetation habitats and recreation activities; and determine the impacts of recreation and tourism for major regions and major vegetation habitats where there have been considerable nature-based recreation and tourism activities.1998 Academic Press     

Is this trail too crowded? A choice experiment to evaluate tradeoffs and preferences of park visitors in Garibaldi Park,British Columbia

Large crowds in parks can be a problem for park managers and visitors. However, perceptions of crowding are difficult to measure due to coping mechanisms deployed by park visitors. Furthermore, perceptions of crowding should not be measured in isolation, but rather as part of a suite of conditions that comprise the visitors’ outdoor experience. We used a dichotomous choice experiment with visual images and eight attributes to estimate park users’ utilities associated with their visitor experience in Garibaldi Provincial Park in British Columbia, Canada. Our visual method allowed us to control for background view and compare user preferences on hiking trails with preferences at final destinations. We find that utilities are more sensitive to crowding at viewpoints than to other aspects of the outdoor experience. Thus, visitor satisfaction and crowding perceptions are more likely to be defined by where visitors have these encounters rather than the total number of encounters.
