N = 406), highlight some important issues concerning the design and management of wildland recreation environments that are
primarily used for mountain biking. For example, bikers were found to significantly prefer water bars above all other tested
soil erosion management techniques; trail erosion factors, including the presence of rocks, roots, and gullies, all added
to biking experiences on average; trail design factors, such as the presence of turns, bumps, jumps, and obstacles, all added
to biking experiences in general. These findings were used to address questions that resource managers should consider when
striving to effectively manage wildland recreation areas primarily used for mountain biking. 相似文献

The wilderness use simulation model applied to Colorado River boating in Grand Canyon National Park,USA 总被引:1,自引:0,他引:1
A modification of the Shechter-Lucas Wilderness Use Simulation Model (WUSM) for peak season boating on the Colorado River through Grand Canyon National Park, USA, is evaluated as a tool for making management decisions. A new microcomputer program to select trip itineraries for inclusion in the WUSM that was developed as part of this study is presented. This program simplifies user input and expands the WUSM's usefulness as a tool for management decisions by randomizing itinerary schedules based on probabilities developed from actual use of sites by canyon visitors. Model usefulness is demonstrated by simulating various management changes and comparing use levels of attraction sites and campgrounds as well as numbers of encounters between parties. The WUSM is being used as part of an ongoing study, to reflect the impact of fluctuating flow regimes through the turbines at Glen Canyon Dam on river trips. 相似文献

Defining acceptable conditions in wilderness 总被引:5,自引:0,他引:5
The limits of acceptable change (LAC) planning framework recognizes that forest managers must decide what indicators of wilderness
conditions best represent resource naturalness and high-quality visitor experiences and how much change from the pristine
is acceptable for each indicator. Visitor opinions on the aspects of the wilderness that have great impact on their experience
can provide valuable input to selection of indicators. Cohutta, Georgia; Caney Creek, Arkansas; Upland Island, Texas; and
Rattlesnake, Montana, wilderness visitors have high shared agreement that littering and damage to trees in campsites, noise,
and seeing wildlife are very important influences on wilderness experiences. Camping within sight or sound of other people
influences experience quality more than do encounters on the trails. Visitors’ standards of acceptable conditions within wilderness
vary considerably, suggesting a potential need to manage different zones within wilderness for different clientele groups
and experiences. Standards across wildernesses, however, are remarkably similar. 相似文献

The dual goals of the Organic Act of 1916 and Wilderness Act of 1964 are to protect natural resources and provide quality
visitor experiences. Park managers need metrics of trail conditions to protect park resources and quality of visitor experiences.
A few methods of sampling design for trails have been developed. Here, we describe a relatively new method, spatially balanced
sampling, and compare it to systematic sampling. We evaluated the efficiency of sampling designs to measure recreation-related
impacts in Rocky Mountain National Park. This study addressed two objectives: first, it compared estimates of trail conditions
from data collected from systematic versus spatially balanced sampling data; second, it examined the relationship between
sampling precision and sampling efficiency. No statistically significant differences in trail condition were found between
the 100-m interval and the spatially balanced datasets. The spatially balanced probability-based dataset was found to be a
good estimate of trail conditions when analyses were conducted with fewer sample points. Moreover, spatially balanced probability-based
sampling is flexible and allows additional sample points to be added to a sample. 相似文献

Using data from a study conducted in the Cranberry Wilderness Area of West Virginia, United States, this paper describes how
a modified importance—performance approach can be used to prioritize wilderness indicators and determine how much change from
the pristine is acceptable. The approach uses two key types of information: (1) indicator importance, or visitor opinion as
to which wilderness indicators have the greatest influence on their experience, and (2) management performance, or the extent
to which actual indicator conditions exceed or are within visitor expectations. Performance was represented by calculating
indicator performance estimates (IPEs), as defined by standardized differences between actual conditions and visitor preferences
for each indicator. The results for each indicator are then presented graphically on a four-quadrant matrix for objective
interpretation. Each quadrant represents a management response: keep up the good work, concentrate here, low priority, or
possible overkill. The technique allows managers to more systematically and effectively utilize information routinely collected
during the limits of acceptable change wilderness planning process.

Legally designated wilderness areas are acknowledged to be an important element in strategies to conserve biological diversity
in United States. However, because of the restrictions on consumptive uses in wilderness, their establishment is normally
contentious. Criteria for establishment have typically been associated with opportunity and aesthetic and experiential values.
Biological data have not normally played a major role in guiding wilderness establishment. We present four wilderness allocation
options for those public lands considered suitable for wilderness designation in Idaho. These options cover the span of choices
presently available to wilderness planners in the state and range from not establishing any new wilderness areas to the inclusion
of all suitable lands in wilderness. All options are evaluated using spatial biological data from the National Biological
Survey's Gap Analysis Project. A conservation strategy that would protect a minimum of 10% of the area occupied by each of
113 native vegetation types and at a minimum 10% of the distribution of each of 368 vertebrate species was evaluated for each
option. Only the inclusion of all suitable lands in wilderness, creating a system of 5.1 million ha came close to achieving
these goals, protecting 65% of the vegetation types and 56% of the vertebrate species. We feel this approach, which allows
planners to evaluate the ecological merits of proposed widerness units along with other values, can provide a means to resolve
the impasse over additional wilderness designation in Idaho. 相似文献

Effects of Place Identity,Place Dependence,and Experience-Use History on Perceptions of Recreation Impacts in a Natural Setting 总被引:1,自引:2,他引:1
It is generally accepted that recreation use in natural environments results in some degree of negative social and environmental impact. Environmental managers are tasked with mitigating the impact while providing beneficial recreation opportunities. Research on the factors that influence visitors' perceptions of environmental and social conditions is necessary to inform sound environmental management of protected natural areas. This study examines the effect of prior experience with the setting and two dimensions of place attachment (i.e., place identity and place dependence) on visitors' perceptions of three types of recreation impacts (i.e., depreciative behavior, environmental impacts, and recreation conflict). Principal components analysis, confirmatory factor analysis, and structural equation modeling were used to test the study hypotheses using data collected from 351 visitors through on-site questionnaires (response rate of 93 percent). The results show that prior experience exhibited a moderate and significant direct positive effect on place identity, place dependence, and visitors' perceptions of recreation impacts. Contrary to study hypotheses and prior research, neither place dependence nor place identity exhibited a significant effect on the dependent variables. The results show that prior experience causes visitors to be more sensitive to depreciative behaviors, environmental impacts, and recreation conflict. These findings raise concerns over potential visitor displacement and deterioration of site conditions. Implications for resource managers are discussed, which include education, modifying visitor use patterns, and site design strategies. 相似文献

The Russian River-Cooper Lake-Resurrection River trail system, on the Kenai Peninsula, Alaska, traverses essential brown bear
habitat. To set management guidelines for this area, the trail system was monitored using questionnaire cards and electronic
trail counters from 1984 through 1987. This helped to determine the extent and type of human use and human-bear encounters
in the area. Management recommendations were intended to reduce the potential displacement of brown bears by hikers and to
inform wilderness users of the proper camping techniques to avoid attracting bears to the campsite. An average of 5800 visitors
hiked or camped along the trail system each year. Encounters between hikers and brown bears averaged 7/yr while encounters
with black bears averaged 35/yr. Minor problems occurred with both the electronic trail counters and the questionnaire. Modilications
to these methods are discussed. A Limits of Acceptable Change format should be considered for the trail system to determine
the character and future direction of recreational activities and monitoring of the trail system should continue in the future. 相似文献

Recreational use of wilderness results in impacts to vegetation and soil in trails and campsites. Traditionally, campsite impact studies have compared campsites receiving various levels of use with unused control areas. Field studies in Sequoia National Park, California, indicate that the degree of impact to vegetation and soils also varies within campsites. The central areas of campsites, where trampling is concentrated, show lower plant species diversity, differences in relative species cover, more highly compacted soils, and lower soil nutrient concentrations than do peripheral, moderately trampled, and untrampled areas within the same campsite. Three years after closure to visitor use, the central areas show less increase in mean foliar plant cover, and soils remain more highly compacted than in previously moderately trampled areas of the same sites. Changes in relative species cover over time are used to assess both resiliency to trampling and species composition recovery within campsites closed to visitor use. 相似文献

Many European countries, including Norway, have a right of common access tradition toward wildland areas for recreational
activity. The “right of any one to move freely over all wildlands except farm fields and gardens” can serve as a paradoxical
barrier to managing wildland areas and users for outdoor recreation. This article discusses the apparent paradox between free
access and management of wildland recreation, the underlying principles of both concepts, and proposes an integrative basis
for how the two concepts can serve the same major goal—freedom of access and use of wildland recreation areas without disturbance
to other users or the resource base. A Norwegian field study is presented with campfire data and management strategies to
illustrate the integrative nature of common access and wilderness management principles for the managing of wildland recreation
opportunities. 相似文献

Indicators are a key component of resource management, but selecting them can be difficult and controversial. This study explores different methods for selecting impact indicators for management of trail conditions by comparing photo survey methods (PSM) with written survey methods (WSM). A total of 661 subjects participated in interviews conducted within Mudeung- Mountain Provincial Park in Kwang-ju, Korea. PSM explained variation in acceptability better than WSM. Six major photo components (in order of importance: area of large rocks on trail, area of wood steps, area of bare roots, area of bare soil, area of small stones, and area of stone steps) explained 84.7% of the variation in acceptability of trail management conditions. This study suggests that PSM can be a useful tool for selecting impact indicators.

Many public land management agencies are committed to understanding and protecting recreation visitor experiences. Parks Canada
is deeply committed to that objective for visitors to Canada’s National Parks. This 2004 study, informed by a 2003 qualitative
study of visitor experiences and influences on those experiences at Auyuittuq National Park in Nunavut, worked to bring 50
potential elements of visitor experiences down to five articulated dimensions of the experience that is currently being received
at this remote eastern arctic park. A hypothesized set of 17 influences on experiences, also reduced to just two factors with
similar response patterns, and with some items that did not flow into the two factors, were used in a regression analysis
to understand the relationship between experiences and factors of influence. A sample of 61.8% (84) of the total recreation
visitor population 16 years of age or older was surveyed during deregistration after the trip. Knowledge about the dimensions
of the experiences currently received and factors of influence on those experiences can be used to guide selection of indicators
for describing objectives and prescribing monitoring protocol. 相似文献

Understanding how setting attributes influence the nature of the visitor experience is crucial to effective recreation management.
Highly influential attributes are useful indicators to monitor within a planning framework, such as Limits of Acceptable Change.
This study sought to identify the setting attributes perceived to have the most profound effect on the ability to have “a
real wilderness experience” and to assess the degree to which attribute importance varied with situational context and visitor
characteristics. To this end, exiting hikers were surveyed at moderate and very high use trailheads in Alpine Lakes Wilderness,
WA (USA), and Three Sisters Wilderness, OR (USA). They were asked about the degree to which encountering varying levels of
different setting attributes would add to or detract from their experience. Attributes with the largest range of effect on
experience, based on evaluations of different levels, were considered most important. The most influential attributes were
litter and several types of campsite interaction—people walking through camp and number of other groups camping close by.
The perceived importance of setting attributes did not vary much between wilderness locations with substantially different
use levels, suggesting that conclusions are robust and generalizable across wilderness areas. There also was little difference
in the perceptions of day and overnight visitors. In contrast, we found substantial variation in the perceived importance
of setting attributes with variation in wilderness experience, knowledge, attachment, and motivation. Our results validate
the emphasis of many wilderness management plans on indicators of social interaction, such as number of encounters. 相似文献

It is difficult to make general recommendations that apply to all ecosystems. There is still a relative dearth of studies
that allow the manager or visitor to come up with specific practices that are the best for their area. The preferred method
of disposal remains to dig a small hole (cat hole) and bury the waste. Other site specific methods are also discussed.
Treatment of drinking water has become standard practice for most backcountry travel. With such treatment, there is little
evidence currently to suggest that the health hazard to humans is great enough to impose further regulation in areas currently
using cat holes. 相似文献

Concerns over the increasing popularity of wilderness recreation have resulted in attempts to determine the amount of use that different areas can tolerate without adverse affects to the resource. Early attempts to establish recreational carrying capacities focused on managers' assessments of biophysical impacts. The perceptions of wilderness visitors, however, are now considered integral to capacity decisions. This study used a stress appraisal framework to understand wilderness visitors' perceptions of on-site conditions. It was based on the premise that negative appraisals of wilderness conditions produce stress and that individual perceptions vary based on personal and situational characteristics. The purpose of the study was to assess the validity of a wilderness-hassles appraisal scale by testing hypothesized relationships between experience-use history (EUH), place attachment, and stress appraisal. Data collection occurred through a postal survey of hikers (n = 385) contacted in the High Peaks and Pemigewasset Wilderness Areas during the summer of 2004. An exploratory factor analysis indicated that stress appraisal is a multi-dimensional construct. Validity testing procedures were restricted to those dimensions that were consistent between study areas and provided partial support for the hassles scale. As hypothesized, EUH did not influence perceptions of wilderness conditions. Place attachment, on the other hand, was positively correlated with stressful appraisals of social and managerial conditions. Although Kruskall Wallis tests revealed significant differences in visitors' perceptions of managerial conditions between study sites, perceptions of social conditions did not vary significantly. Implications for management and recommendations for further refinement of the wilderness hassles construct are discussed. 相似文献

Protected area management involves balancing environmental and social objectives. This is particularly difficult at high-use/high-impact
recreation sites, because resource protection objectives may require substantial site management or visitor regulation. This
study examined visitors’ reactions to both of these types of actions at Annapolis Rocks, Maryland, a popular Appalachian Trail
camping area. We surveyed visitors before and after implementation of camping policies that included shifting camping to designated
newly constructed campsites and prohibiting campfires. Survey results reveal that visitors were more satisfied with all social
and environmental indicators after the changes were enacted. An Importance-Performance analysis also determined that management
actions improved conditions for factors of greatest concern to campers prior to the changes. Posttreatment visitors were least
satisfied with factors related to reduced freedom and to some characteristics of the constructed campsites. Although there
was evidence of visitor displacement, the camping changes met management goals by protecting the camping area’s natural resources
and improving social conditions. 相似文献

A special cascading fixed charge structure can be used to characterize a forest management planning problem in which the objectives are to identify the optimal shape of forest harvest cutting units and simultaneously to assign facilities for logging those units. We describe a four-part methodology that has been developed to assist forest managers in analyzing areas proposed for harvesting. This methodology performs an analysis of harvesting feasibility, computes the optimal solution to the cascading fixed charge problem, undertakes a GASP IV simulation to provide additional information about the proposed harvesting operation, and permits the forest manager to perform a time-cost analysis that may lead to a more realistic, and thus improved, solution. 相似文献

Surface disposal of human waste by the smear method, a suggested but heretofore unexamined technique, was tested in three environments and examined for reductions in fecal mass and fecal indicator bacteria. Substantial reduction in fecal mass was observed after six and fourteen weeks of exposure in all environments, but extensive reduction in fecal indicator bacteria was observed in only the arid and alpine environments. Although surface smears appear favorable to cathole techniques in terms of indicator bacteria reduction, the application of this method is limited by several other factors common to backcountry sanitation situations. It is therefore likely that surface disposal would only be applicable in very remote, low use, alpine and arid settings where lack of soil development precludes the use of catholes and carry-out techniques are otherwise impractical. 相似文献
