Quantification of blue carbon in salt marshes of the Pacific coast of Canada

Abstract. Tidal salt marshes are known to accumulate “blue carbon” at high rates relative to their surface area, which render these systems among the Earth's most efficient carbon (C) sinks. However, the potential for tidal salt marshes to mitigate global warming remains poorly constrained because of the lack of representative sampling of tidal marshes from around the globe, inadequate areal extent estimations, and inappropriate dating methods for accurately estimating C accumulation rates. Here we provide the first estimates of organic C storage and accumulation rates in salt marshes along the Pacific coast of Canada, within the United Nations Educational, Scientific and Cultural Organization (UNESCO) Clayoquot Sound Biosphere Reserve and Pacific Rim National Park Reserve, a region currently underrepresented in global compilations. Within the context of other sites from the Pacific coast of North America, these young Clayoquot Sound marshes have relatively low C stocks but are accumulating C at rates that are higher than the global average with pronounced differences between high and low marsh habitats. The average C stock calculated during the past 30 years is 54 ± 5 Mg C ha−1 (mean ± standard error), which accounts for 81 % of the C accumulated to the base of the marsh peat layer (67 ± 9 Mg C ha−1). The total C stock is just under one-third of previous global estimates of salt marsh C stocks, likely due to the shallow depth and young age of the marsh. In contrast, the average C accumulation rate (CAR) (184 ± 50 g C m−2 yr−1 to the base of the peat layer) is higher than both CARs from salt marshes along the Pacific coast (112 ± 12 g C m−2 yr−1) and global estimates (91 ± 7 g C m−2 yr−1). This difference was even more pronounced when we considered individual marsh zones: CARs were significantly greater in high marsh (303 ± 45 g C m−2 yr−1) compared to the low marsh sediments (63 ± 6 g C m−2 yr−1), an observation unique to Clayoquot Sound among NE Pacific coast marsh studies. We attribute low CARs in the low marsh zones to shallow-rooting vegetation, reduced terrestrial sediment inputs, negative relative sea level rise in the region, and enhanced erosional processes. Per hectare, CARs in Clayoquot Sound marsh soils are approximately 2–7 times greater than C uptake rates based on net ecosystem productivity in Canadian boreal forests, which highlights their potential importance as C reservoirs and the need to consider their C accumulation capacity as a climate mitigation co-benefit when conserving for other salt marsh ecosystem services.

Interplay and Cooperation in Environmental Conservation: Building Capacity and Responsive Institutions Within and Beyond the Pacific Rim National Park Reserve, Canada

Although protected areas (PAs) have become pivotal components in the pursuit of environmental sustainability, they have had mixed success in achieving environmental goals, in part due to internal factors such as governance design and insufficient ability to operate within, and connect to, wider social, economic, and institutional frameworks. A growing body of scholarship reveals that there are fundamental mismatches between rhetoric and practice in state-driven “participatory” conservation, and that state–community cooperation is extremely challenging. This study draws on data from qualitative research on institutions and interactions in conservation planning and management to examine factors influencing collaboration between Parks Canada and Nuu-chah-nulth communities adjacent to the Pacific Rim National Park Reserve. We consider the evolution of policies, institutional arrangements, state-community interactions, and socio-cultural and legal frameworks within which state-led conservation takes place to assess progress in multilevel cooperation. We found that despite differences in degrees of authority and decision-making power, and a land tenure framework that favors the state, there is a shift from domination toward negotiation in the interplay between the federal government and grassroots actors. That shift is linked to the recognition of First Nations’ ancestral tenure and custodianship, and the particularities of grassroots and state leadership. The findings suggest significant progress in sustaining the PA as a multilevel effort, and that cooperation in conservation helps all parties to build capacity for environmental stewardship beyond the PA and to fashion conservation institutions that are responsive to changing social–ecological conditions.

Community perceptions of the contributions of parks to sustainability in Canada

ABSTRACTNational Parks are thought to contribute to sustainability by addressing conservation, social values and local tourism economies. However, some studies challenge these claims, suggesting that parks can create inequitable flows of costs and benefits to local communities. This study focussed on Pacific Rim National Park Reserve, and five nearby communities. Focus groups and 262 random surveys were used to examine perceived benefits and costs of the park to sustainability. The most important perceived benefits were environmental, followed by economic benefits and social benefits. Perceived costs were rated lower, and were most evident regarding economic impacts (e.g. inflated prices, inflated property values). However, perceptions varied substantially by community, particularly with the First Nations village of Esowista where perceived concerns were greater than in other communities. Contrary to expectations, perceptions were less correlated to length of residence, employment in tourism, employment in the park, involvement in park management or income.

The Effect of Ambivalence on On-Leash Dog Walking Compliance Behavior in Parks and Protected Areas

This study employed the theory of planned behavior (TPB) to examine how ambivalence affects compliance of visitors to regulation concerning on-leash dog requirement in a national park setting. Pacific Rim National Park Reserve in British Columbia, Canada, has a substantial challenge with off-leash dogs, which interfere with shorebirds and contribute to habituation of wolves that come to view dogs as prey. Historically, the park has favored indirect visitor education strategies over direct enforcement. These visitor education strategies rely upon frequency and intensity of information, conservation appeal for keeping wolves unhabituated and “wild,” respecting sensitive shorebird habitat, and fear, by presenting dogs as prey. However, the ineffectiveness of current strategies and ongoing visitor noncompliance with dog-leashing regulations has presented a significant challenge, highlighting the importance of theory in developing effective strategies to influence visitor behavior. Following TPB methodology, interviews were conducted with compliers (dogs on-leash) and noncompliers (dogs off-leash) from which a survey was developed. Results found a strong relationship between behavior, intentions, and the three factors that influence intentions: attitudes, subjective norms, and perceived behavioral control. However, relations were weaker between each of these factors and the relevant beliefs thought to be influencing each factor. The next phase of analysis examined ambivalence, which occurs when visitors hold conflicting attitudinal beliefs about a desired behavior. In this ambivalence situation, park visitors may choose not to reflect on beliefs when forming their attitudes about complying with on-leash regulations. Park regulations and communications usually target attitudinal beliefs in order to influence visitor behavior, but under conditions of ambivalence, this kind of strategy may not be effective. In an ambivalence situation, messages to achieve compliance should be directed at influencing norms and perceived control, rather than just attempting to influence attitudes.In addition to messaging, alternative strategies to influence visitor behavior may be warranted that emphasize community level outreach initiatives focused on personal contact. Patrolling and on-leash enforcement in combination with outreach may be more effective. Seasonal closures to sensitive areas during peak migration may also make enforcement a less daunting task of managing visitors in such a large area. Providing an alternative beach area or other location where dogs can run free may also make it easier for park visitors with dogs to engage in compliance behavior. Media, social media, “prompts” that remind people to “leash up,” and messages delivered by a credible source also have the potential to influence on-leash behavior. Subscribe to JPRA

Human Activity and Habitat Characteristics Influence Shorebird Habitat Use and Behavior at a Vancouver Island Migratory Stopover Site.

Pacific Rim National Park Reserve on Vancouver Island, British Columbia, Canada, has 16km of coastal beaches that attract many thousands of people and shorebirds (S.O. Charadrii) every year. To identify locations where shorebirds concentrate and to determine the impact of human activity and habitat characteristics on shorebirds, we conducted shorebird and visitor surveys at 20 beach sectors (across 20 total km of beach) during fall migration in 2011-2014 and spring migration in 2012 and 2013. Using zero-inflated negative binomial regression and a model selection approach, we found that beach width and number of people influenced shorebird use of beach sectors (Bayesian information criterion weight of top model=0.69). Shorebird absence from beaches was associated with increasing number of people (parameter estimate from top model: 0.38; 95% CI 0.19, 0.57) and decreasing beach width (parameter estimate: -0.32; 95% CI -0.47, -0.17). Shorebirds spent more time at wider beaches (parameter estimate: 0.68; 95% CI 0.49, 0.87). Close proximity to people increased the proportion of time shorebirds spent moving, while shorebirds spent more time moving and less time foraging on wider beaches than on narrower ones. Shorebird disturbance increased with proximity of people, activity speed, and presence of dogs. Based on our findings, management options, for reducing shorebird disturbance at Pacific Rim National Park Reserve and similar shorebird stopover areas, include mandatory buffer distances between people and shorebirds, restrictions on fast-moving activities (e.g., running, biking), prohibiting dogs, and seasonal closures of wide beach sections.

The assessment of cultural ecosystem services in the marine environment using Q methodology

Cultural ecosystem services are generally understood to be the non-material value that can be gained through ecosystems such as a sense of well-being, reflection and spiritual enhancement. These are often linked with a sense of place, culture, heritage and identity. The assessment of cultural ecosystem services, particularly in the marine environment is an inherently complex and difficult task, because they often involve making value judgments which can be hard to quantify. Methods applied to determining the value of these services are often focused on their financial value. Whilst methodologies have been developed to assess the non-material importance of these services, this paper argues that Q methodology provides a highly appropriate way of examining unmeasurable values by being able to convert qualitative, subjective data into quantitative information. The research presents two data sets derived from Q methodology which examined stakeholder views of the cultural values from two marine protected areas; the Pacific Rim National Park, Vancouver Island, Canada and an Area of Outstanding Natural Beauty in Chichester Harbour, UK. The relevance of using Q methodology as a valuation mechanism in this type of study is examined and justified; whilst highlighting the advantages of tackling a subject of values and intangibility, highly qualitative information, with a structured, semi-automated and primarily quantitative methodology. The findings show that the case-study areas hold three predominant ‘factors’ of value for its stake holders. These include the protected areas; as a place of care for each other and oneself through the natural world; a place of spirituality; and as a place of freedom and refuge. The paper strongly argues for the use of Q methodology in such a study, which ultimately helps to bring about a depth of information that arguably traditional methods are incapable of in the same capacity.

Singing seaside: Pacific Wrens (Troglodytes pacificus) change their songs in the presence of natural and anthropogenic noise

Abstract Noise pollution poses a significant obstacle to vocal communication. Songbirds rely on acoustic signals for mate choice and territory defense, and masking of these signals can have negative fitness consequences. Prior investigations reveal that birds mitigate the negative effects of acoustic masking by increasing their signal amplitude or by singing with higher minimum frequencies. In this study, we evaluate the responses of male Pacific Wrens (Troglodytes pacificus) to natural ambient noise (ocean surf) and anthropogenic noise (highway traffic) in Pacific Rim National Park Reserve, B.C., Canada. Pacific Wrens, known for their complex songs, are specialists of old-growth forest. We hypothesized that Pacific Wrens would compensate for the effects of ambient noise in their environments through modifications to their songs that enhanced their transmission properties. Recognizing that longer, higher frequency, and more complex signals propagate better in noisy environments, we predicted that Pacific ...

Perceived crowding and encounter norms of KayaKers in Pacific rim national ParK reserve, canada

This article investigates crowding and encounter norms of 375 kayakers visiting the Broken group Islands in Pacific Rim National Park Reserve, Canada. To measure encounter norms, kayakers evaluated photographs showing increasing densities of (a) kayaks on the water, (b) motorboats on the water, and (c) tents at a campsite. Norm curve characteristics helped to define kayaker standards for quality marine tourism and recreation experiences, including minimum acceptable conditions at one time (4.8 kayaks, 2.2 motorboats, 4.7 tents). In addition, significant differences existed between marine (39% felt crowded while on the water) and terrestrial (80% felt crowded while at campsites) perceptions of crowding. Implications for park management include a need to assess the appropriateness of both terrestrial and marine conditions when managing for kayak activity. This may include a consideration of user quotas in marine and terrestrial settings, as well as expanding the number of available campsites.

Geomorphic and sediment volume responses of a coastal dune complex following invasive vegetation removal

ABSTRACTThis paper documents application of an established geostatistical methodology to detect significant changes in a foredune–transgressive dune complex where Parks Canada Agency (PCA) implemented a dynamic restoration program to remove invasive marram grasses (Ammophila spp.) and enhance dynamic dune habitat for an endangered species. Detailed topographic surveys of a 10 320 m2 site in the Wickaninnish Dunes in Pacific Rim National Park, British Columbia, Canada for the first year post‐treatment are compared to a pre‐restoration LiDAR baseline survey. The method incorporates inherent spatial structure in measured elevation datasets at the sub‐landscape scale and models statistically significant change surfaces within distinct, linked geomorphic units (beach, foredune, transgressive dune complex). Seasonal and annual responses within the complex are discussed and interpreted.All geomorphic units experienced positive sediment budgets following restoration treatment. The beach experienced the highest differential volumetric change (+1656 m3) and net sediment influx (+834 m3, 0 · 19 m3 m–2) mostly from supply to the supratidal beach and incipient dune. This sediment influx occurred independent of the restoration effort and was available as a buffer against wave erosion and as supply to the landward dunes. The foredune received +200 m3 (0 · 13 m3 m‐2) and its seaward profile returned to a similar pre‐restoration form following erosion at the crest from vegetation removal and scarping by high water events. Sediment bypassing and minimal change was evident at the mid‐stoss slope with appreciable extension of depositional lobes in the lee. The transgressive dune complex experienced high accretion following restoration activity (+201 m3) and over the year (+284 m3, 0 · 07 m3 m–2) mostly from depositional lobes from the foredune, precipitation ridge growth along the downwind boundary, and growth of existing lobes within the complex. Further integration of this methodology to detect significant geomorphic changes is recommended, particularly for applications where sampling densities are limited or logistically defined.

Monitoring considerations for a dynamic dune restoration project: Pacific Rim National Park Reserve, British Columbia, Canada.

ABSTRACTHistorically, management of coastal dune systems has often involved artificial stabilization of active sand surfaces in order for coastal areas to be more easily controlled and modified for human benefit. In North America, the introduction of invasive grasses, namely European and American beach (marram) grasses (Ammophila spp.) has been one of the most successful strategies used for stabilizing active coastal dune sands. Recent research has demonstrated, however, that stabilization of coastal dunes often leads to reduced landform complexity and resilience, as well as declines in species diversity. More ‘dynamic’ restoration efforts have emerged over the past 20 years that encourage dune mobility and aeolian activity in order to provide a more resilient biogeomorphic system. In North America, there is generally little research relating restoration methods and outcomes to geomorphic responses despite the fundamental importance of sedimentary processes and dune morphodynamics in broader ecosystem function. This paper aims to better situate dynamic dune restoration within current geomorphic understanding. A brief review of key terms and concepts used in the emerging field of dynamic dune restoration is provided and expanded upon with respect to geomorphologic considerations. A case study of a recent dynamic restoration effort in Pacific Rim National Park Reserve, British Columbia, Canada is provide to demonstrate how these concepts are applied. Introduction of European marram at this site, coupled with a warming climate and increased precipitation in recent decades at this site, is thought to be associated with a rapid decline in aeolian activity, system stabilization and accelerated ecological succession. Preliminary results on the response of the dune system to mechanical removal of Ammophila are presented to provide the foundation for a research framework to guide the broader restoration project. Recommendations for improving treatment methodologies and monitoring protocols are provided to aid future restoration projects of this nature. Copyright © 2013 John Wiley & Sons, Ltd.

First Nations Values in Protected Area Governance: Tla-o-qui-aht Tribal Parks and Pacific Rim National Park Reserve

Over the past few decades there has been increasing attention paid to ‘shared’ forms of governance and to the creation of new protected areas (PAs) that are designed to address ‘non-biological’ goals and values. The rationale for these initiatives has, in part, been based on the belief that well-designed systems of protected area governance will help to deliver desired outcomes and meet linked sociocultural, economic and environmental objectives. Addressing these questions has become increasingly important in British Columbia, where a number of First Nations are asserting increasing control over existing state-run protected areas, as well as establishing new protected areas and designing governance systems for them that deliver outcomes consonant with cultural beliefs, values and goals. This paper reports on an in-depth case study of the Tla-o-qui-aht Tribal Parks and the Pacific Rim National Park Reserve, with a focus on comparing how these physically adjacent protected areas with different objectives each attempt to meaningfully engage the Tla-o-qui-aht First Nation in PA governance.

Stakeholder Evaluation Priorities for Demonstrating Marine Protected Area Effectiveness at the Pacific Rim National Park Reserve, Canada

This study addresses the often advocated involvement of stakeholder groups in all aspects of marine protected area management including the development of an evaluation program. In the absence of clear management objectives, the study investigates the opinions of five non-aboriginal stakeholder groups on the importance, purpose and content of an evaluation at Pacific Rim National Park on the West coast of Canada. Information needs of stakeholders are identified in an open question format as well as based on a list of pre-defined indicators. Findings indicate that both approaches identify unique indicators. Indicators revealed in the open-ended format are more detailed and reflect the local context of the park reserve. Presenting a list of indicators, however, illustrates evaluation priorities more clearly as frequencies of responses for priority indicators are higher. Statistical analysis reveals general agreement among the five groups on the importance, purpose, and content of an evaluation. Only a few differences are obvious in the choice of evaluation indicators between commercial and non-commercial stakeholder groups.

Who is Being Rescued in Canadian National Parks?

There has been a growing body of literature reviewing the epidemiology of injuries, illnesses, and search and rescue (SAR) operations in National Parks in the United States. There are 42 National Parks in Canada that experienced over 12 million visitors in 2010. Little research has been published to date on SAR trends in Canadian National Parks. To review the current literature regarding SAR operations in Canadian National Parks and assess the need for further research in this area. Articles in the MEDLINE database were identified that analyzed SAR operations or injury and illnesses occurring in Canadian National Parks. The Parks Canada website was reviewed for relevant information available to the public regarding safety and SAR operations in National Parks. One peer-reviewed article was identified that analyzed the epidemiology of SAR operations in Banff, Yoho, and Kootenay National Parks. No further relevant articles were found. From 1994 to 1998, Parks Canada reported a yearly average of 1400 safety incidents in National Parks. Pacific Rim National Park Reserve (PRNPR) is reported to experience the most SAR operations from all National Parks, with the West Coast Trail accounting for 80 to 100 incidents annually. There were 20 accident reports available from the 7 Mountain National Parks in 2010, with 4 self-reported “near-miss” accidents. A paucity of data exists regarding SAR operations in Canadian National Parks. Epidemiological studies conducted in the United States may not be extrapolated to Canada due to possible differences in climate, activity rates, and safety programs. A recent study of US National Parks demonstrated the most common SAR environment was the mountain environment, whereas in Canada it is reported that PRNPR, a coastal environment, experiences the highest number of SAR operations yearly. Further research into these incidents is needed before critical analysis and improvement of prevention strategies targeting high-risk areas and activities can be made.

Analysis of coastal dune dynamics, shoreline position, and large woody debris at Wickaninnish Bay, Pacific Rim National Park, British Columbia

Large woody debris (LWD) and colonizing vegetation alter the sediment budgets and stability of coastal dune systems. In British Columbia, LWD on beaches consists largely of historical escape logs f...

Developing MPA performance indicators with local stakeholders’ input in the Pacific Rim National Park Reserve, Canada

Along with an increase in the establishment of marine protected areas (MPAs), the need arises to assess if designated MPAs are achieving their goals and objectives. A first step in this process is the identification of MPA performance indicators against which to evaluate MPA management. This study investigates the development of MPA performance indicators using an in situ approach by including diverse stakeholder groups in the process. The results show that local stakeholders identify a range of MPA performance indicators in all stages of the management cycle and in diverse MPA indicators categories. Statistical analysis reveals that multiple groups identify distinct performance indicators. Fishermen groups primarily mention governance performance indicators in the planning and output stage. Other groups most often cite biophysical and social outcome performance indicators. The findings demonstrate distinct management expectations towards MPA performance among included stakeholder groups. The study also shows that the integration of multiple groups is necessary for the identification of MPA performance indicators as the groups identify distinct performance indicators.

Stakeholder Opinions on the Assessment of MPA Effectiveness and Their Interests to Participate at Pacific Rim National Park Reserve, Canada

As the number of marine protected areas (MPAs) is globally increasing, information is needed on the effectiveness of existing sites. Many protected area agencies however have limited resources and are unable to evaluate MPA effectiveness. An evaluation conducted entirely by the managing agency may also lack credibility. Long-term monitoring and evaluation programs should ideally offer opportunities for participation of diverse groups in the selection of evaluation indicators and their assessment. A participatory approach has the potential to enhance evaluation capacity, to increase credibility and acceptance of results, to strengthen relationships between managers and local stakeholders, and to address more locally relevant information. Using a case study approach, this paper investigates diverse stakeholder groups' opinions on the design of an evaluation and their interest to participate in an assessment. Respondents were most interested in the assessment of MPA achievements and outcome indicators. Most groups identified a range of government agencies and stakeholders that should participate in an assessment but only half of all respondents were interested to participate in monitoring activities. Most frequently mentioned limitations for more participation were a lack of time and money, but also governance shortcomings such as limited participation possibilities and not paying enough credit to stakeholders' input. Participation interest was also influenced by occupation, place of residency, and familiarity with the marine environment. Differences exist among stakeholders about suitable evaluators and preferred monitoring partners, which could affect the credibility of evaluation results and affect monitoring activities.

Visitor perceptions of the role of tour guides in natural areas

This paper explores the potential of tour guides to contribute to the protection of natural areas by educating their customers through interpretation and modeling environmentally appropriate behaviors. Applying Cohen's (1985) model of the guides' role, modified by Weiler and Davis (1993), as a framework, it examines the potential role that kayak tour guides can play in shaping the experience of visitors to one marine area, the Pacific Rim National Park. It uses two approaches to explore the perceptions of clients about the role of kayak guides using: (1) a pre- and post-trip questionnaire and (2) participant observation. Results indicate that five of the six roles were rated high in importance, but one role, the communication role, was not as important. Comparing performance with importance attached to each role revealed congruence with five roles, but lower levels of performance in relation to importance with the role of “motivator of responsible behavior”. Variability within all of the importance and performance measures suggest that for some individuals, performance did not match importance, highlighting the need to consider market segmentation in future studies. These findings are discussed within the ecotourism paradigm, and their implications for protected area management and for visitor behavior modification are considered.

The impact of recreational boat traffic on Marbled Murrelets ( Brachyramphus marmoratus)

This study evaluated the impact of small boat traffic on reaction distances of Marbled Murrelets ( Brachyramphus marmoratus), in the marine waters of Pacific Rim National Park Reserve, British Columbia, Canada. Observers on moving boats recorded the minimum distance the boat came to murrelets on the water, and any disturbance reaction (fly, dive, no reaction). Out of the 7500 interactions 11.7% flew, 30.8% dove and 58.1% exhibited no flushing reaction. Using a product-limit analysis, we developed curves for the proportion of Marbled Murrelets flushing (dive or flight) as a function of reaction distance. Overall, the majority of Marbled Murrelets waited until boats were within 40 m before reacting, with 25% of the population reacting at 29.2 m. A stepwise Cox regression indicated that age, boat speed, and boat density (loaded in that order), significantly affected flushing response. More juveniles flushed than adults (70.1 versus 51.7%), but at closer distances. Faster boats caused a greater proportion of birds to flush, and at further distances (25% of birds flushed at 40 m at speeds >29 kph versus 28 m at speeds <12 kph). A stepwise logistic regression on diving and flight responses indicated that birds tended to fly completely out of feeding areas at the approach of boats travelling >28.8 kph and later in the season (July and August). Other secondary variables included; boat density and time of day. Discussion focused on possible management actions such as the application of speed limits, set back distances, and exclusion of boat traffic to protect Marbled Murrelets.

Effects of knowledge, personal attribution and perception of ecosystem health on depreciative behaviors in the intertidal zone of Pacific Rim National Park and Reserve

Human activities levy a biological cost on ecosystems as resources are accessed and utilized at rates which are often incompatible with inherent ecosystem processes and structures. The recreational impact of humans upon intertidal zones and particularly fucoid algal assemblages is one major threat facing coastal ecosystems. The effect of human values, knowledge and perception in effecting biologically costly behaviors has rarely been examined. We hypothesize that with respect to intertidal zones: (1) Personal attribution and perception of ecosystem resiliency are more important than knowledge in determining the extent of depreciative behaviors individuals engage in, and; (2) Individuals who are uncertain about ecosystem resiliency will behave in a manner consistent with the ‘precautionary principle’. We measured the depreciative behavior, and the attitudes and perceptions to ecosystem resilience, of visitors to Wick Headland in Pacific Rim National Park, British Columbia. Attitudes, knowledge, perceptions, and personal attribution were measured using questionnaire survey and structured interviews undertaken in situ. Depreciative behaviors of visitors were discreetly observed and correlated to the questionnaire survey and interview responses. We show that visitors who recorded greater knowledge of intertidal ecology engaged in more depreciative behaviors than visitors recording less knowledge. Visitors who perceived high ecosystem resilience in the intertidal zone engaged in significantly more behaviors eliciting biological cost than those who perceived low ecosystem resilience. Visitors who recorded uncertainty regarding ecosystem resilience engaged in significantly more depreciative behaviors than those who perceived low ecosystem resilience but slightly fewer depreciative behaviors than those who perceived high ecosystem resilience. Personal attribution was inversely correlated to the mean number of depreciative behaviors. We discuss the relevance of these results to the management of intertidal zones and marine protected areas, to multiple use management, the management of visitor impact, and natural resource use.

Visitor management and ecological integrity: one example of an integrated management approach using Decision Analysis

In this paper we argue in favour of using a decision analysis framework for more integrated decision-making when managing protected areas. Such an approach will enable agencies to balance between the frequently conflicting goals of visitor management and ecological integrity. We present a case study from the West Coast Trail in Pacific Rim National Park Reserve, BC, Canada, in which we use a hybrid of ELECTRE and AHP to establish a ranking of several management options. We conclude by suggesting that such a more formal framework constitutes a more objective decision support tool, assists in framing relevant management questions and tradeoffs, and at the same time provides guidance for data collection.
