Remote ecosystems in Canadian Rocky Mountain parks and protected areas are being pressured by indirect impacts of human activities across the landscape. Ecological impacts can result from a variety of stressors such as climate change, fire suppression and prescription, visitor use, invasive species, and surrounding land-uses. With intensified challenges relating to logistics and moral issues inherent in remote ecosystem management (Higgs and Hobbs, 2010; Higgs and Roush, 2011), managers of these landscapes continue to struggle with questions of "what do we do here?" For ecological restoration and conservation management, historical landscape changes (predominantly following years of fire suppression and rapid climate change) are complicating decisions and our understanding of ecological processes. While intervention may become increasingly necessary for maintaining biodiversity and ecosystem services under conditions of rapid change (Hobbs et al., 2011), direct action may not be the most appropriate tactic, especially when lacking adequate information and foresight (Harris et al., 2006; Higgs and Roush, 2011). This study investigates observable historical remote landscape change in two protected areas in the Canadian Rockies, and examines the resulting implications for management and restoration. Present conditions in Willmore Wilderness Park and Mount Robson Provincial Park were evaluated in a comparative case-study approach. The influence of factors such as jurisdiction, climate, socioeconomics and settlement history were seen to strongly shape how environmental changes impacted management efforts and decisions. Long-term landscape changes were observed through repeat photography with the Mountain Legacy Project. Through focus groups using photo-elicitation with park managers, repeat photo pairs guided discussion. I pursued this research question: "how do long-term landscape changes influence conservation and restoration objectives in remote mountain ecosystems?" This also incorporated subsidiary questions: "what are the inherent challenges in managing (and restoring) remote ecosystems?” and “how could managers of remote ecosystems best approach these issues in the face of rapid ecological change?” Significant landscape changes are observed in both parks and include glacier retreat, forest stand aging, valley infill (encroachment) and upward movement of the treeline ecotone. While ecological changes are seen as significant and as threatening to various park values and public safety, efforts to better understand these changes or address them are limited. The majority of remote ecosystem management efforts in both parks are indirect (passive), with the exception of fire management. This is largely due to capacity and resource constraints, and agency recreation mandates and visitor needs monopolizing manager focus. Suggested restoration efforts would assist climate adaptation and reduce indirect impacts without placing notable pressure on remote ecosystems. The use of repeat photography for monitoring of ecological change is a strong possibility for parks management, particularly if public engagement through citizen science was implemented to minimize dependence on management resources. / Graduate / 0368 / 0768 / jlfalk@uvic.ca

Fueled by ubiquitous access to mobile phones, and a massive population of nearly 3 billion unbanked people around the globe, mobile commerce is evolving as a disruptive technology. Simultaneously, mobile payments are surfacing as a killer application within the mobile commerce context (Hu et al. 2008). Undeniably, the proliferation of wireless mobile technology provides much-needed access to vital information, and financial services for disenfranchised, unbanked populations. In addition, technological innovations offer first-time opportunities for suppliers of goods and services in a market context to gain competitive advantages while enhancing their economic viability. According to Portio Research, the volume of mobile payments rose significantly from $68.7 billion U.S. dollars in 2009, with predictions of $633.4 billion U.S. dollars by the end of 2014 (mobithinking.com 2012). Despite exponential growth in the number of mobile subscribers globally, and widespread adoption of mobile commerce, acceptance rates for mobile payment applications have lagged (Dahlberg et al. 2007, Ondrus et al 2009, Ondrus and Lyytinen 2011). Yet examinations of factors inhibiting the widespread acceptance of mobile payments are relatively sparse. Using Social Network theory, this research examines factors affecting engagement in mobile payments. The researcher posits that four primary elements influence mobile payment engagement: 1) the relationships between and amongst inter-organizational alliance members; 2) the prevailing regulatory environment; 3) the state of existing banking and technology infrastructures, and 4) an assessment of economic opportunity. The research outcomes from this exploratory examination led to the development of a comprehensive model for mobile payment engagement, and strongly suggest that ties between and amongst firms in inter-organizational alliances help ensure the success of mobile payment engagement. Support was found for the following suppositions: 1) similarities and relations (continuous ties) help establish a framework and understanding amongst alliance members as to each party’s goals and objectives; and 2) interactions and flows (discrete ties) between and amongst inter-organizational alliance members strengthen the overall ties between alliance members while solidifying a viable working relationship amongst the alliance members. This study employs a qualitative approach to obtain real world insight into the dynamism of the mobile payment arena. A model is then proposed to practically examine mobile payment engagement opportunities. From a theoretical perspective, the research contributes to the extant scholarly knowledgebase pertaining to engagement in mobile payments.

This research examined the potential for protected areas with camas (including tall camas, Camassia leichtlinii (Baker) Wats., and common camas, C. quamash (Pursh) Greene; Liliaceae (Agavaceae)) habitat to support the renewal of Central Coast Salish camas traditions while at the same time maintaining and even expanding their ecological restoration and conservation goals. For many generations Central Coast Salish Peoples of northwestern North America have cultivated camas plants and harvested, processed, and consumed their edible bulbs in large quantities. Today, after camas use has almost completely disappeared from their lives, some Indigenous peoples are working to restore camas habitats and cultivation practices on southern Vancouver Island and neighbouring areas. Tall camas and common camas can still be found growing in many Garry oak ecosystems, which, due to the decreased range and the large proportion of rare species found within them, are frequently the focus of ecological restoration and conservation efforts. I interviewed people from the resource management and First Nations communities to gain an understanding of the current interests, opportunities, challenges, and potential approaches for incorporating traditionally based camas harvesting and management into protected areas today. Protected areas were identified as important areas for teaching traditional plant cultivation techniques to younger generations, and as bulb and seed banks for ethnoecological restoration projects. Overall, managers of protected areas and First Nations participants were receptive to collaborating on management of camas populations. Anticipated or existing challenges or concerns included ecological uncertainties of harvesting disturbance, ensuring safety, finding funding, and gaining trust. I conducted one season of experimental camas harvesting in a Garry oak savannah near Duncan, BC within an ecological preserve and monitored the effects of this harvesting on the extant camas populations, on surrounding plant communities, and on soil porosity. Harvesting of, primarily tall, camas bulbs, at both low and medium intensity, did not affect the weight or abundance of camas bulbs or the quantity, stem height or flowering/fruiting potential of the camas populations in the following year. Harvesting significantly reduced the abundance of Kentucky bluegrass (Poa pratensis) and common snowberry (Symphoricarpos albus, but significantly increased the abundance of Scotch broom (Cytisus scoparius) common cleavers (Galium aparine), hairy cat’s ear (Hypochaeris radicata), and nipplewort (Lapsana communis). Harvesting significantly reduced the level of soil compaction. Using the insights gained from the interviews and experimental harvesting I have proposed an “Ethnoecological Restoration Support Model”. This model explains how protected areas can support cultural restoration both within and outside of protected areas while maintaining and even expanding upon current conservation and restoration goals. / Graduate / 0329 / 0740 / 0471 / kproctor@uvic.ca

Riparian ecosystems of the southwestern United States are highly valuable to both the ecological and human communities which surround them. Over the past century, they have been subject to shifting management practices to maximize human use, control, ecosystem service, and conservation. This creates a complex relationship between water policy, management, and the natural ecosystem necessitating research on spatial and temporal dynamics of riparian vegetation. The San Acacia Reach of the Middle Rio Grande, a 60 mile stretch from the San Acacia Diversion Dam to San Marcial, has experienced multiple management and river flow fluctuations over the past 80 years, resulting in threats to riparian and aquatic ecosystems. This research was completed through the use and analysis of multi-source remote sensing data, GIS, and a review of the on-the-ground management decisions to better understand how the location and composition of the riparian vegetation has been affected by these shifting practices. This research focused on four phases, each highlighting different management practices and river flow patterns during the last 80-years. Each of these periods provides a unique opportunity to observe a direct relationship between river management and riparian land cover response and change. Overall, management practices reduced surface river flows and limited overbank flooding and resulted in changes in the composition, density, and spatial patterns of the vegetation, including increased non-native vegetation growth. Restoration efforts over the past few decades have begun to reduce the presence of non-native species. Despite these changes, this ecosystem was shown to be extremely resilient in maintaining its function/service throughout the entire study time frame.
