A Conservation Strategy Maintaining Ecological Systems And A CONSERVATION STRATEGY MAINTAINING ECOLOGICAL SYSTEMS AND COMMUNITIES IN THE FACE OF CHANGE NOVEMBER 26, 2007 For The Cariboo-Chilcotin Beetle Action Coalition By Richard L. Case MSc RPBio R.L Case & Associates and Barbara J. Coupé RPF Arboreal Communication Services September 2007 CCBAC Interim EDWG Sector Strategies CCBAC is very pleased to make the Economic Development Working Group interim sector strategies available for use by the sector participants and stakeholders, the CCBAC working groups, the various ministries within the provincial and federal governments, and most importantly the citizens of the Cariboo-Chilcotin. CCBAC is compelled to make this information available as quickly as is possible in order to meet its objective of developing and growing the overall economic activity within the Cariboo-Chilcotin. CCBAC will identify each completed sector strategy as an ‘interim’ document through the use of this cover letter. To CCBAC this means that the interim strategy is a ‘stand alone’ document at the time of its release, and that the interim sector strategy has not been ‘integrated’ with other interim sector strategies in any manner or form. The use of the information contained within the interim sector strategy is the responsibility of the user. CCBAC does not endorse or support any specific use or proposal that uses the interim sector strategy material. CCBAC supports all interim sector strategies in principle only at this time. CCBAC intends to begin the sector strategy integration process immediately. At the conclusion of the integration process CCBAC intends to have completed a community diversification plan for the entire CCBAC area. The interim sector strategies will be an integral part of this plan. For additional information on the attached interim sector strategy, please contact the members of the sector strategy advisory committee, members of the CCBAC EDWG, or Keith Dufresne CCBAC Manager. On the behalf of the CCBAC Board Keith Dufresne, CCBAC Manager 2 Cariboo-Chilcotin “Conservation” Sector Strategy Strategy Process Overview November 2007 The following is a brief overview of the Conservation Strategy development process from its commencement in June 2006 to its completion as an “interim strategy” in November 2007. In contrast to the economic sector strategies which follow a generic strategy outline the Conservation Strategy addresses eight deliverables outlined in the CCBAC RFQ – Conservation Strategy Coordinator. The deliverables are designed to reflect region wide conservation interests and concerns relative to the mountain pine beetle epidemic and it is to be integrated with the other sector strategies. The following briefly outlines the strategy development process from commencement to completion. June 2006 – A day long “Sustainability and the Environment in Transition” forum gathered key players (32 attendees, 90 invited) from the conservation community to identify issues and build a proposal to CCBAC for a Conservation Strategy. September 2006 – A contractor is hired to co-ordinate the development of a Conservation Strategy guided by an advisory group representing conservation interests identified at the June forum (see acknowledgements). December 2006 – A proposal for strategy development is approved by the CCBAC Board. January-March 2007 – One hundred conservation-based groups and organizations from across the region are interviewed for their concerns regarding future environmental sustainability issues especially those driven by the mountain pine beetle epidemic. March-July 2007 – Key issues are synthesized from the inventory and a strategy to ensure community sustainability from an ecosystems perspective is developed. August 2007 – A draft strategy document is presented to the CCBAC Board for review. October 2007 – The Conservation Strategy is approved in principle by the Board with minor revisions requested. November 2007 – Final revisions and additions are completed and the strategy becomes a public document to be integrated with the other strategies in the Regional Diversification Plan. The report is posted to the CCBAC website 3 PREFACE Despite its heft, the Conservation Strategy is a cursory look at many of the “green” topics of the day as they pertain to the Cariboo-Chilcotin. The looming economic ramifications of the mountain pine beetle epidemic instigated this and other strategies for the Cariboo-Chilcotin Beetle Action Coalition. As stated in the official proposal, the intent of the Conservation Strategy is to ensure that environmental quality, resource conservation, local long-term security, and community stability are considered during strategy planning processes. The Conservation Strategy is a “never ending story.” It has been written against a backdrop of rapidly evolving policy, public opinions, and scientific/technological advances. Sustainability at every level of scale—local, national, and global—is the issue of the millennium. People are concerned and want to know what their options are. The authors welcome any comments, concerns and suggestions regarding this strategy. Our contact information is listed below. We look forward to hearing from you.

  • DISTURBANCE HISTORY and ITS INFLUENCE on DROUGHT TOLERANCE of INTERIOR DOUGLAS-FIR (Pseudotsuga Menziesii Var
    DISTURBANCE HISTORY AND ITS INFLUENCE ON DROUGHT TOLERANCE OF INTERIOR DOUGLAS-FIR (Pseudotsuga menziesii var. glauca (Beissn.) Franco) IN THE CARIBOO-CHILCOTIN REGION OF BRITISH COLUMBIA, CANADA by Neil P. Thompson B.Sc., University of Maine, 2013 THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN NATURAL RESOURCE AND ENVIRONMENTAL STUDIES UNIVERSITY OF NORTHERN BRITISH COLUMBIA August 2017 © Neil P. Thompson, 2017 Abstract: Disturbance—the death of trees due to external forces such as wildfire or windstorms— drives forest stand dynamics and shapes ecosystems. Natural disturbances arising from the interaction of climate, topography, and established tree species have often occurred with some regularity, resulting in apparently perpetual renewal of particular forest structures. Minor changes in climate can have profound impacts on these disturbance regimes, breaking historically observed cycles and introducing novel stand conditions. Long-term historical baselines are critical to understanding such changes. Observational records are often inadequate, especially in western North America, where 400 year-old stands are common but reliable data are generally unavailable prior to the 20th century. I use tree ring analysis to investigate the history of Douglas-fir beetle and western spruce budworm infestations, and the influence of partial disturbances on the drought tolerance of surviving trees, developing baseline understanding of disturbance interactions in interior British Columbia. No evidence is found of any outbreaks of western spruce budworm or Douglas- fir beetle that exceed the magnitude of outbreaks in the early 21st century, suggesting that recent outbreaks represent historically high levels of insect activity. Both natural and anthropogenic partial disturbances are demonstrated to positively affect the drought tolerance of surviving trees in old-growth remnants and younger managed stands, respectively.

    Technical Summaries and Supporting Information for Emergency Assessments Steelhead Trout Oncorhynchus mykiss (Thompson River and Chilcotin River populations) John Neilson, Co-chair, Marine Fishes Subcommittee, COSEWIC Eric Taylor, Chair, COSEWIC February 2018 ASSESSMENT SUMMARY Assessment Summary – February 2018 Common name Steelhead Trout (Thompson River population) Scientific name Oncorhynchus mykiss Status Endangered Reason for designation This wildlife species faces a number of threats, including declining habitat quality both in marine and freshwater environments, and bycatch mortality from Pacific salmon fisheries. The number of spawning fish was variable with little trend prior to 2000. Since then, the population has declined dramatically (79%) over the last three generations and it is now the lowest on record. The 177 mature fish observed in the most recent survey are only about 9.5% of the pre-2000 mean. If the current rate of decline persists for another three generations, the number of spawning fish will decline to 37, which is 2.0% of the pre-2000 abundance.

  • The Wineglass Assemblage, Lower Chilcotin River, South-Central British
    The Wineglass assemblage, lower Chilcotin River, south-central British Columbia: Late Permian volcanic and plutonic rocks that correlate with the Kutcho assemblage of northern British Columbia Paul Schiarizza1,a 1 British Columbia Geological Survey, Ministry of Energy, Mines and Natural Gas, Victoria, BC, V8W 9N3 a corresponding author: [email protected] Recommended citation: Schiarizza, P., 2013. The Wineglass assemblage, lower Chilcotin River, south-central British Columbia: Late Permian volcanic and plutonic rocks that correlate with the Kutcho assemblage of northern British Columbia. In: Geological Fieldwork 2012, British Columbia Ministry of Energy, Mines and Natural Gas, British Columbia Geological Survey Paper 2013-1, pp. 53-70. Abstract Late Permian volcanic and plutonic rocks that were identified along the lower Chilcotin River by Read (1993) were examined to evaluate a possible correlation with the Kutcho assemblage of northern British Columbia, host to the Kutcho Creek volcanogenic massive sulphide deposit. These rocks, herein named the Wineglass assemblage, include a lower volcanic unit of mainly basalt, an upper volcanic unit that includes rhyolite, basalt, and felsic volcaniclastic rocks, and an intrusive body of tonalite, quartz diorite, and granodiorite, referred to as the Wineglass pluton. The Wineglass assemblage is correlated with the Kutcho assemblage on the basis of its striking lithologic similarity, overlapping U-Pb zircon ages, similar unconformable relationship with an overlying Triassic-Jurassic sedimentary sequence, and similar relationship to structurally overlying Cache Creek Complex. Clastic sedimentary rocks that unconformably overlie the Wineglass assemblage are part of the predominantly Late Triassic-Middle Jurassic Cadwallader arc terrane. Expanding the definition of Cadwallader terrane to include the Wineglass assemblage and correlatives makes for a compelling correlation with Wallowa terrane, in the Blue Mountains region of northeastern Oregon and west-central Idaho.

  • PART 2 Conclusion of a 2,500-Kilometre Off-Road Odyssey Through B.C.’S Remote Backcountry UNCHARTED Story and Photos by Larry Pynn TERRITORY
    PART 2 Conclusion of a 2,500-kilometre off-road odyssey through B.C.’s remote backcountry UNCHARTED Story and photos by Larry Pynn TERRITORY 38 CYCLE CANADA JANUARY 2016 39 ritish Columbia’s Chilcotin region is big country with larger-than-life characters, several of them authors. B Paul St. Pierre wrote short stories about ranch life, Chris Czajkowski detailed one woman’s experiences alone in the wilderness, and Rich Hobson recounted the early days of cattle ranching. As Murray Comley and I ride west from the Fraser Canyon into the Chilcotin, we seek yet another locally renowned figure, Chilco Choate. The retired big-game guide-outfitter described his life in three books, including one that explored his rocky relationship with the Gang Ranch. At 81, Chilco lives alone at Gaspard Lake where someone set him up on a computer with satellite Internet. He sent me an email message weeks ago with directions to his place, but today they make about as much sense as a diamond hitch on a pack horse. Murray resorts to his GPS and leads us along good gravel to a six-kilometre dirt backroad extending to Gaspard Lake. Murray’s 1995 BMW R1100G is equipped with knobby tires, but my loaner KTM 1190 Adventure is not. I’m also a short guy on a big bike unable to touch the ground without shifting my butt to one side of the seat. “If it gets too rough you can always turn back,” Murray offers. Of course, once you are half way, you’re all the way in.

  • Appendix F: History of the Churn Creek Protected Area
    Churn Creek Protected Area Appendix F: History of the Churn Creek Protected Area Archaeological evidence shows the Churn Creek area has a long history of First Nations’ use. This archaeological evidence includes cultural depressions from pithouse villages and surface scatters of stone tool debris. In addition to this physical evidence, a number of oral accounts of the occupation and use of the area from the distant past to the present exist. However, since no formal archaeological work has been done of these sites beyond surface surveys, dates and other details are not currently available. Although specific archaeological information is not currently available for Churn Creek beyond the fact that is was used for winter settlement, general patterns of use identified in the wider Fraser River area may be used to suggest the probable time frame and lifeways that occur at Churn Creek. Research undertaken by archaeologists suggests that a distinct culture based on hunting ungulates had developed on the Interior Plateau as long as 7,000 years ago and a tradition of river fishing and Douglas-fir forest adaptation was well established as long as 5,500 years ago. Archaeologists believe pithouses were in use as far back as 4,300 years ago, reflecting an adaptation to the economic patterns that were in evidence when Europeans arrived in the 1800’s. These patterns included living in essentially permanent pithouse villages during the winter months and travelling during the remainder of the year to procure plant, animal and mineral resources. Portions of these resources were then stored for winter consumption in the village.
