Applications of Paleolimnology in Ecosystem Monitoring for Sirmilik National Park: Developing Indicators of Ecological Integrity

Devlin, Jane Erica 22 July 2010 (has links)
Water chemistry and bioindicators (diatoms and invertebrates) were examined for freshwater lakes, ponds and streams in two regions within Sirmilik National Park, northern Baffin Island, Nunavut. Significant differences were recorded between the water chemistry and diatom and invertebrate assemblages of the two regions. Modern diatom assemblages were explained mainly by specific conductivity, ORP, pH, temperature, elevation and distance from the coast. Paleolimnological techniques were applied to a sediment core from Lake BY14 on Bylot Island. Fossil diatom assemblages indicate increases in nutrients and temperature since 1935 AD. The diatom biostratigraphy does not show as large an increase in diversity and production since the middle 20th century as has been noted elsewhere, and this may be a reflection of the more nutrient-rich status of the lake relative to other Arctic lakes.

Adaptive governance for fire management planning : a case study on Prince Albert National Park, Saskatchewan

Almstedt, Ǻsa 25 November 2010
Fire is a natural ecological process in the boreal forest, but also a threat to human lives, properties and other values at risk. The challenge is to find a way to manage fire where both the positive and negative aspects of fire are effectively balanced. This is especially important since more frequent and intense wildfires are predicted in the future due to climate change. There is also a need for increased cooperation across jurisdictions to improve the efficiency and effectiveness of Canadian fire management. To address the current and future challenges of fire management, this thesis argues that an effective and adaptive governance approach is needed.<p> The purpose of the study was to develop principles, criteria and indicators of adaptive governance and to apply this framework to fire management planning in Prince Albert National Park (PANP), Saskatchewan. Because of the need to include other agencies with fire responsibilities, the study also focused on the interagency cooperation with Saskatchewan Environment (SE), the provincial ministry responsible for wildfires.<p> Principles, criteria and indicators of adaptive governance were identified based on literature on good governance, adaptive management, adaptive governance, and wildfire specific literature. A qualitative research approach was then used to collect data mainly through semi-structured interviews with representatives from Parks Canada (both from PANP and at the national level) and SE, and document analysis of fire plans and strategies.<p> This study shows that many aspects of adaptive governance have already been implemented in PANP, so that principles and criteria of inclusiveness, legitimacy, foresight, leadership, and many aspects of performance-oriented and adaptiveness have been at least partially met. Yet, there is a need to improve information-sharing and communication, especially across jurisdictions. In terms of the interagency cooperation between PANP and SE, having different mandates is the biggest challenge, but it does not prevent cooperation. Throughout the years both agencies have worked out ways to deal with differences in their mandate and fire management strategies. Having a dialogue to try to understand each other�s mandate and respect each other has been and continues to be a key factor in the cooperation. Finally, maintaining and retaining social capital may be crucial to future success in fire management planning, both from an intra- and from an interagency perspective.

Apparent Fate, 2010: Dismantling the Notion of Photographic Truth

MacDonald, Kelsey M. 04 May 2010 (has links)
When creating a current work, artists cannot ignore the images that have preceded theirs. The history of a medium and the related history of subject matter is vital to the meaning of a new art work. Each sign and symbol has a connotation out of the artists’ control. The developed meaning of a symbol is inseparable for the viewer regardless of the acknowledgment of that meaning by the artist. To work with imagery and not address it’s historical context is to perpetuate it’s meaning. The only way to not state what has already been stated is to critically engage with the preexisting meaning of the imagery. An artist can combine symbols to create dual meanings or juxtapositions of meaning, or present the imagery in a way that complicates what it already signifies. “Apparent Fate,”my combined negative, photographic mural, uses imagery from Yosemite National Park to comment on photography’s function or purpose in history and in the current economic, political, environmental, and social conditions in California and society’s current stance on Manifest Destiny. How have the ideas of innate rights over people and places changed over time in American culture?

Island Inquiries: Nature, Culture and Environmental Management

Mortensen, Leah Plaisier 20 April 2012 (has links)
I looked at the restoration of Santa Cruz Island National Park to examine the interconnected relationship between nature and culture in the United States. I conducted literature research on the changes in conceptual construction and environmental policy, and grounded my analysis in interviews I conducted with National Park Employees involved in the Primary Restoration Plan. Through the language of their responses, I analyzed how specific words, process and possibility, affect the restoration and consequently our concept of nature.

Coeur d’Alene salamander abundance, distribution, and habitat use in Mount Revelstoke National Park of Canada

Larson, Lisa Irene 05 1900 (has links)
The Coeur d’Alene salamander (Plethodon idahoensis) is a species of special concern throughout its global range, which includes southeastern BC (COSEWIC, Nov 2007), Idaho, and Montana, due to disjunct populations and sensitivity to human disturbance. Within the Interior Cedar-Hemlock forest on Mount Revelstoke, BC, Coeur d’Alene salamanders occur at their highest abundance between 600 m and 800 m. Beyond the Mount Revelstoke National Park boundaries, the low-order stream habitat of this species is subject to disturbance from forestry, mining, road building, road maintenance, and watercourse diversions such as run-of-the-river hydro projects. We conducted nocturnal salamander surveys and assessed habitat characteristics on 12 Sites (750 m² – 1000 m² stream transects) along three streams from June through September 2006. Coeur d’Alene salamanders were detected from 600 m - 1000 m on seven of the 12 study sites. Relative abundance of Coeur d’Alene salamanders ranged from 0.005 ± 0.001 per m² to 0.025 ± 0.005 per m² on six sites below 950 m. Coeur d’Alene salamanders occurred at an average of 0.001 ± 0.001 per m² at 972 m, the only site above 950 m where we detected salamanders. Our capture-mark-recapture efforts of three surveys per month in June and August yielded a very low recapture rate (3.95 %). Coeur d’Alene salamanders are challenging to enumerate due to their vertical distribution within the soil and underlying geological material. Neonate, juvenile, and adult Coeur d’Alene salamanders were observed from June to September and the highest proportion of neonates occurred in June, soon after the salamanders emerged from winter hibernation. Results of a logistic regression analysis of 1-m² plots reflected the importance of fine scale habitat characteristics (quadrat gradient, boulder, cobble, moss, grass, and shrub) in addition to site-level habitat features (water volume and elevation) that in combination describe the association of Coeur d’Alene salamanders with cool and moist conditions. Coeur d’Alene salamanders appear to select streambed habitat during warm, dry periods, which may be a behavioural response to minimize dehydration during periods of activity at the surface of the forest floor.

Environmental Impacts of Tourism in Khao Yai National Park, Thailand

Phumsathan, Sangsan 2010 August 1900 (has links)
Knowledge of visitor impacts is critical for sustainable tourism management in national parks. The focus of past tourism impact research on national parks is either on bio-physical impacts (conducted as recreation ecology research) or on social impacts (human dimensions, including environmental perception and crowding). Research integrating these two dimensions has been rarely conducted. This research aims to fill this gap through the integrative approach that attempts to understand current biophysical impacts of visitor activities in a national park, and it examines how visitors perceive these impacts. The primary objectives of this dissertation are 1) to provide a synthesis of existing of bio-physical impacts of visitor activities in the Khao Yai National Park (KYNP) and 2) to examine visitors’ perception of those impacts. Also, the factors affecting visitors’ perception are analyzed. Both qualitative and quantitative methods were used in this study. Previous impact studies conducted in KYNP were reviewed. A visitor survey was conducted between December 2008 and February 2009. The questionnaires were distributed to 628 domestic and 40 international visitors. The 38 KYNP official interviews were completed. Based on previous impact research in KYNP, the most common bio-physical impacts include soil compaction, removal of humus layer, erosion, plant damage, soil and root exposure, water quality deterioration, disturbance and feeding wildlife. Other environmental impacts include noise pollution and garbage accumulation. The results indicate that more than 30 percent of visitors do not recognize the negative results of their activities. With the exception of vegetation and water impacts, overall, visitors perceive the impacts as less severe than the actual impacts. Environmental impacts are rated differently by the KYNP officials, domestic, and international visitors. Also, significant differences were found among birders, hikers, and campers. The key factors influencing impact perceptions include income level, education level, residential location, park visitation experience, length of stay in KYNP, recreation activity, frequency of activity, group type, and group size. It is suggested that both the quality and the quantity of visitor impact research are needed to construct the body of knowledge of impacts in KYNP. A long-term impact monitoring is required to sustain the ecological integrity in KYNP.

Interpretation Of Cultural Heritage Sites The Case: Boston National Historical Park In The U.s.a.

Yildirim Esen, Sibel 01 February 2007 (has links) (PDF)
This study focuses on how cultural heritage interpretation can effectively be planned and operated as an integral part of preservation process. The ICOMOS Charter for the Interpretation and Presentation of Cultural Heritage Sites, which was initiated by the International Council on Monuments and Sites (ICOMOS), offers professional principles for effectively interpreting cultural heritage sites. This study apply these principles as analysis and evaluation criteria of the case study. The Charter principles include &lsquo / access and understanding&rsquo / , soundness of &lsquo / information sources&rsquo / , attention to &lsquo / setting and context&rsquo / , preservation of &lsquo / authenticity&rsquo / , planning for &lsquo / sustainability&rsquo / , concern for &lsquo / inclusiveness&rsquo / , and importance of &lsquo / research, evaluation and training&rsquo / . Considering the necessity of correlating these international principles with interpretation practices, this study analyzes and assesses interpretation at the Boston National Historical Park, a unit of the National Park Service in the US / and at the same time tests the practicality of the Charter principles. This park is composed of eight nationally significant historical sites located separately in an urban context. This study examines certain aspects of the park that affect the effectiveness of its interpretation activities i.e., management policies, organizational model, partnerships with stakeholders, fiscal resources, management planning, and interpretive planning. Besides on-site interpretation at three sites of the park - the Charlestown Navy Yard, Old South Meeting House and Paul Revere House- are analyzed in detail within to the ICOMOS Charter framework. Finally, recommendations have been developed for the ongoing work of the ICOMOS, for the Boston National Historical Park as well as for other cultural heritage sites.
