Carrier Sekani Tribal Council Aboriginal Interests & Use Study On
Carrier Sekani Tribal Council Aboriginal Interests & Use Study on the Enbridge Gateway Pipeline An Assessment of the Impacts of the Proposed Enbridge Gateway Pipeline on the Carrier Sekani First Nations May 2006 Carrier Sekani Tribal Council i Aboriginal Interests & Use Study on the Proposed Gateway Pipeline ACKNOWLEDGEMENTS The Carrier Sekani Tribal Council Aboriginal Interests & Use Study was carried out under the direction of, and by many members of the Carrier Sekani First Nations. This work was possible because of the many people who have over the years established the written records of the history, territories, and governance of the Carrier Sekani. Without this foundation, this study would have been difficult if not impossible. This study involved many community members in various capacities including: Community Coordinators/Liaisons Ryan Tibbetts, Burns Lake Band Bev Ketlo, Nadleh Whut’en First Nation Sara Sam, Nak’azdli First Nation Rosa McIntosh, Saik’uz First Nation Bev Bird & Ron Winser, Tl’azt’en Nation Michael Teegee & Terry Teegee, Takla Lake First Nation Viola Turner, Wet’suwet’en First Nation Elders, Trapline & Keyoh Holders Interviewed Dick A’huille, Nak’azdli First Nation Moise and Mary Antwoine, Saik’uz First Nation George George, Sr. Nadleh Whut’en First Nation Rita George, Wet’suwet’en First Nation Patrick Isaac, Wet’suwet’en First Nation Peter John, Burns Lake Band Alma Larson, Wet’suwet’en First Nation Betsy and Carl Leon, Nak’azdli First Nation Bernadette McQuarry, Nadleh Whut’en First Nation Aileen Prince, Nak’azdli First Nation Donald Prince, Nak’azdli First Nation Guy Prince, Nak’azdli First Nation Vince Prince, Nak’azdli First Nation Kenny Sam, Burns Lake Band Lillian Sam, Nak’azdli First Nation Ruth Tibbetts, Burns Lake Band Ryan Tibbetts, Burns Lake Band Joseph Tom, Wet’suwet’en First Nation Translation services provided by Lillian Morris, Wet’suwet’en First Nation. -

Food Web E.2. Electronic Appendix
E.2. Electronic Appendix - Food Web Elements of the Fraser River Basin Upper River (above rkm 210) Food webs: Microbenthic algae (periphyton), detritus from riparian vegetation and littoral insects (especially midges) are key components supporting fish production in the mainstem upper Fraser and larger tributaries. Collector-gatherers (invertebrates feeding on fine particulate organic material) are the most abundant functional feeding group, making up to 85% of the invertebrate species on the latter two rivers. Smaller tributaries are dominated by collector, shredder and grazer insect feeding modes (Reece and Richardson 2000). There is a general increasing trend in insect abundance from the headwaters of the main river to the lower river (Reynoldson et al. 2005). Juvenile stream-type Chinook rear along the shorelines of the upper river and tributaries and some overwinter under ice as the river margins usually freeze over here. Juvenile Chinook diets in the main stem and tributaries include larval plecopterans, empheropterans, chironomids and terrestrial insects (Homoptera, Coleoptera, Hymenoptera and Arachnida; Russell et al. 1983, Rogers et al. 1988, Levings and Lauzier 1991). Rainbow trout and northern pikeminnow consume mainly sculpins in the Nechako River as well as a variety of insects (Brown et al. 1992). Stressors: Water quality and habitat conditions have changed food webs in specific locations in the upper river. However, compared to other rivers in North America, water quality is good (Reynoldson et al. 2005), even with five pulp mills currently operating in the megareach. The food web of the Thompson River was stimulated in the past by low concentrations of bleached Kraft pulp mill effluent released into the river (Dube and Culp 1997); it is not known if this is still happening as treatment techniques for effluent have changed. -
Fish 2002 Tec Doc Draft3
BRITISH COLUMBIA MINISTRY OF WATER, LAND AND AIR PROTECTION - 2002 Environmental Indicator: Fish in British Columbia Primary Indicator: Conservation status of Steelhead Trout stocks rated as healthy, of conservation concern, and of extreme conservation concern. Selection of the Indicator: The conservation status of Steelhead Trout stocks is a state or condition indicator. It provides a direct measure of the condition of British Columbia’s Steelhead stocks. Steelhead Trout (Oncorhynchus mykiss) are highly valued by recreational anglers and play a locally important role in First Nations ceremonial, social and food fisheries. Because Steelhead Trout use both freshwater and marine ecosystems at different periods in their life cycle, it is difficult to separate effects of freshwater and marine habitat quality and freshwater and marine harvest mortality. Recent delcines, however, in southern stocks have been attributed to environmental change, rather than over-fishing because many of these stocks are not significantly harvested by sport or commercial fisheries. With respect to conseration risk, if a stock is over fished, it is designated as being of ‘conservation concern’. The term ‘extreme conservation concern’ is applied to stock if there is a probablity that the stock could be extirpated. Data and Sources: Table 1.

Acipenser Transmontanus) and Implications for Conservation
1968 Hierarchical patterns of population structure in the endangered Fraser River white sturgeon (Acipenser transmontanus) and implications for conservation Andrea Drauch Schreier, Brian Mahardja, and Bernie May Abstract: The Fraser River system consists of five white sturgeon (Acipenser transmontanus) management units, two of which are listed as endangered populations under Canada’s Species at Risk Act. The delineation of these management units was based primarily on population genetic analysis with samples parsed by collection location. We used polysomic microsatellite markers to examine population structure in the Fraser River system with samples parsed by collection location and with a genetic clustering algorithm. Strong levels of genetic divergence were revealed above and below Hells Gate, a narrowing of the Fraser canyon further obstructed by a rockslide in 1913. Additional analyses revealed population substructure on the Fraser River above Hells Gate. The Middle Fraser River (SG-3) and Nechako River were found to be distinct populations, while the Upper Fraser River, although currently listed as an endangered population, represented a mixing area for white sturgeon originating from SG-3 and Nechako. Differences between these results and previous genetic investigations may be attributed to the detection of population mixing when genetic clustering is used to infer population structure. Résumé : Le système du fleuve Fraser consiste en cinq secteurs de protection de l’esturgeon blanc (Acipenser transmontanus), dont deux comprenant des populations figurant sur la liste des populations en voie de disparition en vertu de la Loi sur les espèces en péril du Canada. La délimitation de ces secteurs de protection a principalement reposé sur l’analyse génétique des populations d’échantillons groupés selon le lieu d’échantillonnage. -

Tolko Industries, through the Forest Investment Account (FIA), provided the funding for this assessment, and allowed the project to be completed on the most critical coho producing streams both within and outside Tolko’s timber license operating boundaries. In addition, we would like to acknowledge the assistance and support of the North Thompson Indian Band. The Simpcw people have a vested interest in ensuring fish, and in particular salmon species, have quality spawning and rearing habitat available. Their dedication to this cause initiated the project. Finally, we would like to thank Cascadia Natural Resource Consultants Ltd. for their high quality mapping services, without which, some of these culverts would not have been located!
