    CONVERGENCE AND COLLABORATION: INTEGRATING CULTURAL AND NATURAL RESOURCE MANAGEMENT By STEPHEN JOHN MALINS B.A., University of Victoria, 1990 A thesis submitted in partial fulfillment of the requirements for the degree of MASTER OF ARTS in ENVIRONMENT AND MANAGEMENT We accept this thesis as conforming to the required standard ______________________________ Dr. Alice MacGillivray, Thesis Supervisor Fielding Graduate University ______________________________ ______________________________ Thesis Coordinator Michael-Anne Noble, Director School of Environment and Sustainability School of Environment and Sustainability ROYAL ROADS UNIVERSITY March 2011 © Stephen John Malins, 2011 Convergence and Collaboration ii ABSTRACT Protected heritage area management is challenged by conflicting priorities perpetuated by the real and perceived dichotomy between cultural and natural resource management, their practitioners, their disciplines, and their values. Current guidelines promote integrating cultural and natural resource management to ensure holistic management of all values within a protected heritage area. This paper uses the management of the Cave and Basin National Historic Site to illustrate challenges in protecting both historic and natural resources. A qualitative inductive study included analysis of interview and focus group data for the site and similar protected heritage areas. The gap between integrative policies and the tendency for uni-disciplinary approaches to the practice of managing protected heritage areas is investigated. Five barriers to integration, such as lack of awareness, and five methods for progress, including facilitated inclusion, are examined. The author proposes collaborative, sustainable, values-based practices for the successful integration of cultural and natural resource management. Convergence and Collaboration iii ACKNOWLEDGEMENTS I am indebted to a number of people who have seen me through this journey from tilting at windmills to slaying of dragons.

For example, prior till and lake sediment Mountain map area (NTS 93 M/1) by the British geochemistry surveys in the Nechako River map ania Columbia Geological Survey as part of a comprehensive (NTS 93F) to the south were successful in delineating survey of the entire Babine copper porphyry belt.

These reports are narrative outlines of how Indian and non-native populations have used these -rivers, with emphasis on navigability, tidal influence, riparian interests, settlement patterns, commercial use and fishing rights. These historical reports were requested by the Interdepartmental Reserve Boundary Review Committee, a body comprising representatives from Indian Affairs and Northern Development [DIAND], Justice, Energy, Mines and Resources [EMR], and chaired by Fisheries and Oceans. The committee is tasked with establishing a government position on reserve boundaries that can assist in determining the area of application of Indian Band fishing by-laws.

The Pacific NorthWest LNG Project (the Project) is proposed to be located primarily on federal lands and waters administered by the Prince Rupert Port Authority approximately 15 kilometres south of Prince Rupert, British Columbia. At full production, the facility would receive approximately 3.2 billion standard cubic feet per day, or 9.1 x 107 cubic metres per day, of pipeline grade natural gas, and produce up to 20.5 million tonnes per annum of LNG for over 30 years. The Project would include the construction and operation of a marine terminal for loading LNG on to vessels for export to Pacific Rim markets in Asia.

  • Riparian Management and the Tailed Frog in Northern Coastal Forests
    Forest Ecology and Management 124 (1999) 35±43 Riparian management and the tailed frog in northern coastal forests Linda Dupuis*,1, Doug Steventon Centre for Applied Conservation Biology, Department of Forest Sciences, University of British Columbia, Vancouver, BC, Canada V6T 1Z4 Ministry of Forests, Prince Rupert Region, Bag 5000, Smithers, BC, Canada V0J 2N0 Received 28 July 1998; accepted 19 January 1999 Abstract Although the importance of aquatic environments and adjacent riparian habitats for ®sh have been recognized by forest managers, headwater creeks have received little attention. The tailed frog, Ascaphus truei, inhabits permanent headwaters, and several US studies suggest that its populations decline following clear-cut logging practices. In British Columbia, this species is considered to be at risk because little is known of its abundance, distribution patterns in the landscape, and habitat needs. We characterized nine logged, buffered and old-growth creeks in each of six watersheds (n 54). Tadpole densities were obtained by area-constrained searches. Despite large natural variation in population size, densities decreased with increasing levels of ®ne sediment (<64 mm diameter), rubble, detritus and wood, and increased with bank width. The parameters that were correlated with lower tadpole densities were found at higher levels in clear-cut creeks than in creeks of other stand types. Tadpole densities were signi®cantly lower in logged streams than in buffered and old-growth creeks; thus, forested buffers along streams appear to maintain natural channel conditions. To prevent direct physical damage and sedimentation of channel beds, we suggest that buffers be retained along permanent headwater creeks. Creeks that display characteristics favoring higher tadpole densities, such as those that have coarse, stable substrates, should have management priority over less favorable creeks.

The Office of the Wet’suwet’en (OW) presents this submission to the Northern Gateway Joint Review Panel. This submission is a component of the Wet’suwet’en response in respect of the proposed Northern Gateway project within Wet’suwet’en territory. 2. The Wet’suwet’en are stewards of the land. They are here to protect their traditional territories and to ensure that future generations of Wet’suwet’en are able to live and benefit from all that their ancestral land provides. The Wet’suwet’en are not opposed to commercial and economic development on their traditional territories as long as the proper cultural protocol is followed and respect given.
