Dear Participants of the Inaugural BCTWS Conference & Workshop, We listened to your feedback on the Membership Survey, and as a result have built our annual conference to include many opportunities to meet, interact, and share information with other wildlife biologists from across the Province, while becoming better informed about current and changing provincial issues. To capture these concepts, we selected our conference theme of BC Connections: Our Future Together. We would also like to acknowledge that during our conference we are gathering on the traditional, ancestral, unceded territory of the Sylix/Okanagan people. The idea is to keep the meeting action-packed and intimate so that professional connections and lasting friendships can be easily made. We have included different forums for sharing and learning about hot topics across the province, including standard Open-Paper and Poster Programs and a Rapid-Paper Program. The Rapid-Papers will allow members to quickly communicate activities important to them, creating greater opportunities to stimulate discussion during breaks, and allow members to get to know one another and identify opportunities for collaboration. Scaling up from personal connections, we are excited to hear the keynote address from Jennifer Psyllakis Director of Wildlife and Habitat, Ministry of Forests, Lands, Natural Resource Operations and Rural Development, “Insight & Vision: Navigating a Career in Natural Resource Management”. We are also looking forward to engaging with the fantastic panel we’ve assembled to discuss British Columbia’s developing Species-At-Risk legislation. And make sure you stay till the end when we will have an important discussion on how to have your voice represented provincially during a Conservation Affairs Committee discussion. The BCTWS takes the future of British Columbia’s wildlife seriously. We believe the greatest contribution we can make to secure our legacy is through support of our students and young professionals. It is clear to me you also share this sentiment, indicated by so many having readily volunteered to attend our “Speed-Networking Session.” We have been graciously supported by several fantastic organizations (pages 4-5), so please remember to thank them for their important contribution to our Chapter. You too can help British Columbia’s future wildlife students by grossly over-bidding on our silent auction items. Our intent is for this conference to be fun and engaging, so I hope you brought your positive energy and plan to enjoy yourselves while simultaneously building a community of forward- thinking and engaged wildlife biologists. I thank you for your attendance and appreciate you doing your part to build a lasting and vibrant BC Chapter of The Wildlife Society. Sincerely, J. Scott Yaeger President / 2019 Conference Chair BC Chapter of The Wildlife Society 2

Oral Presentations (In Alphabetical Order) Artelle K.A.1, M. L. Bourbonnais, J. D. Reynolds, P. C. Paquet, M. S. Adams, H. M. Bryan, K. A. Field, C. N. Service, and C. T. Darimont 1 Postdoctoral Fellow University of Victoria, Victoria BC,&Raincoast Conservation Foundation, Sydney BC, kartelle@gmail.com Using culturally important focal species to inform conservation: spatial assessment of grizzly bears and protected areas in the Great Bear Rainforest The need for conservation that addresses both ecological and cultural dimensions is increasingly being recognized. We illustrate how species of high cultural importance provide opportunities for addressing both, focusing on grizzly bears (Ursusarctos horribilis), which have significant cultural and ecological importance. Specifically, we conducted spatial capture-recapture modeling on data from a non-invasive monitoring project that spans territories of, and is run in partnership with, the Haíɫzaqv, Kitasoo/Xai’xais, Wuikinuxv, and Nuxalk First Nations. We characterized the density of grizzly bear activity centres from 2014-2017 across a 28,500 km2 study boundary and identified hotspots as: 1) areas with activity centre densities in the 90th percentile, or 2) significant spatial congregations of high activity centre densities, identified by the Getis-OrdGi* statistic. We found gaps in the overlap between hotspots and existing protections under of the ‘Great Bear Rainforest Agreement’: over half of 1) male (59%) and female (52%) upper percentile hotspot area and 2) male (56%) and female (51%) Gi* hotspot area remain unprotected under current land use designations. These results identify potential conservation gaps, identify areas where additional protection might provide particular benefit, and more broadly illustrate the potential benefits from empirical inquiry on the stewardship of culturally important wildlife. Botten N.1 1 MSc Candidate, University of Northern British Columbia, Prince George BC,botten@unbc.ca Is the nutritional quality of wildlife forage reduced by the persistence of glyphosate herbicide in plant tissues? Glyphosate, the most widely used herbicide worldwide, is the top choice for use on BC’s forests after harvesting, to prevent competition for commercially-significant conifers. When glyphosate is sprayed on forest cut blocks, various factors result in some plants receiving a sublethal dose. Surviving plants may store and translocate glyphosate molecules within their tissues, and glyphosate may thus persist in plant tissues for an extended duration of time. I am investigating the duration of glyphosate persistence in plant tissues, by analyzing the shoot and root tissues of 6 species of perennial forest plants that I collected last summer in forest cut blocks sprayed with GBH over a period of time ranging from 1 to 12 years ago. Mammals such as moose and bears are known to frequent recently-logged areas in search for preferred foods. A known chelating agent, glyphosate readily binds to certain metal ions, a property that may have a negative effect on the bioavailability of key nutrients in glyphosate-containing plants. It is this effect that glyphosate may have on nutritional quality of wildlife forage that I will be further investigating. The results of my research will be of use to forest and wildlife managers in the vegetation- management decision-making process. 11
Bryan H. A.1, Bateman, M. Adams, J. Ehlers, T. Levi, G. Mowat, P. Paquet, and C. Darimont 1 Raincoast-Mitacs Postdoctoral Scholar, University of Victoria, Victoria BC, and Raincoast Conservation Foundation, Sydney BC,heabry@gmail.com Temporal variation in grizzly bear growth and body size reveals large-scale phenotypic change across British Columbia Growth and body size are fundamental life history traits that are shaped by individual and environmental conditions. Examining variation in growth trajectories over time may therefore provide insight into the responses of populations to environmental change. Accordingly, we examined temporal trends in grizzly bear skull size (width and length) using a dataset of bears killed in British Columbia between 1973 and 2006 (n = 6723). By applying novel incremental growth models, we found that bears born in 2006 grew faster and reached 95% asymptotic body size (a proxy for age at first reproduction) at an earlier age compared with bears born in 1973. These findings suggest that large-scale processes affect bear phenotypes. Our analysis also revealed that bears in warmer climates are larger and grow faster compared with bears in cooler climates. This trend may reflect the nutritional benefits of living in warmer climates with higher productivity of herbaceous foods. Collectively, these results provide insights into the environmental conditions that influence phenotypic traits, which in turn may help predict the consequences of environmental change on wildlife. Burgar J.1, J. Fisher, and C. Burton 1 Postdoctoral researcher, University of Victoria, Victoria BC, and University of British Columbia, Vancouver BC, joburgar@mail.ubc.ca Evaluating camera trap surveys as an effective means of monitoring remote ungulate populations. Camera trap surveys are increasingly being used for wildlife monitoring but their effectiveness at monitoring remote ungulate populations has yet to be determined. To do so we are conducting a multi- year camera trap study within a caribou range affected by wildfire and anthropogenic disturbance. We deployed 58 cameras using a 2 factorial design: in/out of wildfire; on/off seismic lines. Half the cameras were deployed the first field year and the remaining the second field year. We are estimating the densities of boreal woodland caribou (Rangifertarandus caribou) and moose (Alcesalces) using hierarchical Bayesian spatial models. Preliminary results suggest inter-annual variability and spatial segregation of ungulates within the study area. We estimated caribou density using spatial mark-resight models across three temporal periods and found estimates were similar, with slightly higher densities during the winter and lower densities during the pre-calving periods. We used spatial count models to estimate moose densities during the summer period; our estimates were comparable to provincial estimates. Camera trap surveys can be an effective tool to monitor remote populations, producing density estimates similar to other survey methods, with the added benefits of capturing inter-annual variability in density, space-use, and surveying the broader boreal mammal community.

Interim Assessment Protocol for Moose – Assessing and Managing Cumulative Effects in British Columbia. Moose are one of five high-value resources identified for provincial assessment under British Columbia’s (B.C.) Cumulative Effects Framework (CEF). Moose are a high priority species for the Province, which has legal authority for its conservation and management. The importance of this species is reflected in the objectives established for moose through legislation, regulation, and policy. Moose are a conspicuous and iconic part of British Columbia’s fauna that have environmental, economic, social and cultural importance. Moose are a wide-ranging species that depend upon multiple, well-connected and functioning habitat with properly functioning ecosystem processes. As such, moose are susceptible to cumulative impacts on their habitat and their populations from extensive land use activities and disturbances. As a species that can tolerate, and may even benefit from, some human activities on the landscape, moose-human interactions are common and complex. The purpose of the interim protocol is to provide a standardized, transparent and repeatable method for evaluating cumulative effects on moose across the province of B.C. The protocol consists of two assessment components: 1) habitat, and 2) population. Results from the assessment provide a systematic and comprehensive approach to describing, rating, and estimating risk that will assist in guiding and informing strategic responses to moose management in B.C. It is expected that results from a regional review and validation process will potentially clarify, standardize and improve the interim protocol. Carson S.1 1 1079 Raymer Ave, Kelowna BCsheacarson1@gmail.com A Career as a Wildlife Biologist or Zoologist- Why me? As a teenager about to graduate high school and make my plunge into adulthood, I am beginning to experience the common thread of questions about what I plan to do after high school. Up until this year, I tended to question what career path I wanted to take based on my personal goals and what I believe I can accomplish. It was not until I became involved in higher level science classes, like biology, that I found a fascination with the surroundings that our Earth provides for us, especially the animals contained in them. I recognized my affection towards animals and love for the outdoors to discover a career path as a Wildlife Biologist or Zoologist. In my opinion, the advantages of working in such a field are numerous. However, the one that stands out the most for me is the feeling of making a difference in the fight for the protection of our world’s most beautiful species and explore the many mysteries each one holds. That is the main reason I currently strive towards a more conservation-based job in this field. I look forward to conversations with you all to solidify my choice. Constantinou A.1 1 University of British Columbia, Vancouver BC,alexia.constantinou@rogers.com How do variable retention forest harvesting methods affect terrestrial mammals in interior BC? Forest harvesting is part of the economic backbone of British Columbia, but the widespread use of clearcutting can be problematic for wildlife. Terrestrial mammal species that depend on forest cover and 13
structural diversity face a homogenized landscape after harvesting. In the face of increasing forest disturbances and climate change, effects of natural resources harvesting on mammals must be evaluated. Scientists and managers must collaborate to determine best practices for industry and conservation of wildlife communities. Partial harvest methods may be the key to mitigating the effects of clearcut harvesting on biodiversity and to combining ecological and economic goals in managed landscapes. As part of ongoing MSc research, I will use wildlife camera traps and small mammal live trapping to determine the effects of a gradient of four different forest harvesting treatments on terrestrial mammal species: clearcut, 60% canopy retention, 30% canopy retention and seed tree retention. The study areas also span a latitudinal gradient from the Kootenays to north-central BC, which allows for analysis of variation in response to harvesting treatments across climates. This research will impact forest management as it pertains to wildlife habitat across the province. Eckert L.1, N. Ban, C. Owens, F. Moola, C. Darimont 1 Doctoral Student, University of Victoria, Victoria BC,eckertleckert@gmail.com Indigenous Knowledge and Environmental Assessment in Canada – implications for wildlife Large industrial projects often fragment wildlife habitat and increase human-caused mortality. These impacts are common in Canada, despite formal Environmental Assessment (EA). EA, a western environmental decision-making process, affects landscapes and human well-being via ruling on if and how development proposals proceed. For millennia pre-colonization, and today, Indigenous peoples use Indigenous Knowledge (IK) to inform environmental decision-making. Via observation and culturally- transmitted learning, Indigenous peoples use IK to establish landscape-scale management strategies. Scholarship has examined the interaction and tensions between these EA paradigms, often criticizing the ability of EA to engage meaningfully with IK. In 2018, the Canadian government proposed Bill C-69 to amend the 2012 EA Act. Addressing this opportunity, we explore obstacles at the interface of IK and EA via a literature review and qualitative analyses. Our results identify obstacles to improving relationships between IK and EA, some of which are surmountable (e.g. failures to engage in best practices, alongside financial, temporal, and resource limitations, etc.), whereas others are substantial (e.g. knowledge incompatibilities, histories and presence of colonization, asymmetry in power structures, etc.). Drawing on this synthesis, we summarize recommendations towards authentic incorporation of IK into EA in ways that support landscapes for wildlife alongside Indigenous rights and self-determination. Field K.A.1, P. C. Paquet, K.Artelle, G. Proulx, R. K. Brook, C. T. Darimont 1 MSc Student, University of Victoria, Victoria BC, andRaincoast Conservation Fellow, Sydney BC, fieldkate2@gmail.com Publication reform to safeguard wildlife from researcher harm. Despite abundant focus on responsible care of laboratory animals, we present an evidence-based argument that inattention to the maltreatment of wildlife constitutes an ethical blind spot in contemporary animal research. We begin by reviewing significant shortcomings in legal and institutional oversight, arguing for the relatively rapid and transformational potential of editorial oversight at journals in preventing harm to vertebrates studied in the field and outside the direct supervision of institutions. Our analysis of 206 journals suggests that Animal Care (AC) policies are either absent (34%), weak, incoherent, or neglected by researchers. Presence of AC guidelines was positively associated with impact factor and animal welfare legislation in the country of origin, and negatively associated with 14
open access status. Straightforward changes to animal care policies in journals could provide a practical, effective, and rapidly imposed safeguard against unnecessary suffering. The ARROW (Animal Research: Reporting on Wildlife) guidelines we propose here, coupled with strong enforcement, could result in significant changes to how animals involved in wildlife research are treated. The research process would also benefit. Sound science requires animal subjects to be physically, physiologically, and behaviorally unharmed. Accordingly, publication of methods that contravenes animal welfare principles risks perpetuating inhumane approaches and bad science. Ford A.T.1, A. H. Ali, S. R. Colla, S. J. Cooke, C. T. Lamb, J. Pittman, D.Shiffman, and N. J Singh 1 Assistant Professor, UBC-Okanagan, Kelowna BC,adam.ford@ubc.ca Averting harmful outcomes in conservation. Conservation relies on cooperation among different interest groups and the effective and appropriate use of evidence to make decisions that have positive outcomes for both people and biodiversity. Negative outcomes are likely to occur when these two dimensions are ignored or misunderstood, leading to direct harm to populations and indirectly to conservation via alienated partnerships, wasted resources, confused public, and delegitimized evidence. We document case studies where a failed appreciation for cooperation, evidence, or both have eroded efforts to conserve wildlife populations. Averting harmful conservation requires greater adherence to processes that elevate the role of evidence in decision making and that place collective, long-term benefits for biodiversity over the short-term gains of individuals or groups. Gillingham M.P1., and M. M. Mumma 1 Professor, University of Northern British Columbia, Prince George BC, michael@unbc.ca Determining factors that affect survival of Moose in Central British Columbia Moose (Alcesalces) and their habitat are valued by many British Columbians and management actions should be science-based. Over the last decade, some moose populations in interior BC have declined by 50–70% while others are stable or increasing. Declines coincided with mountain pine beetle (Dendroctonusponderosae) outbreaks and related salvage harvesting and road building — landscape changes that could influence the distribution and abundance of moose, predators and hunters. In 2013, FLNRO initiated a 5-year, provincially coordinated program during which 446 cow moose were collared across 6 study areas involving many partners. Mortalities (121) resulted from predation (wolf [42%], bear [7%], cougar [4%], unknown [3%]), apparent starvation (14%), human harvest (13%), health-related (6%), accidents (4%) and unknown causes (7%). We used selection of collared moose to identify meaningful thresholds for moose response to time since burn and time since clearcutting. We are using a survival modelling approach employing landscape, forest structure, and anthropogenic features to identify key factors that affect moose survival. We are also contrasting habitat selection between cow moose that lived and died during the study. When combined these analyses are identifying key management levers for moose in central BC.

Using expert knowledge to identify conservation outcomes and management options for wolverine (Gulogulo) In 2017 wolverine (Gulogulo) were listed in the federal Species at Risk Act as a species of Special Concern across Canada. As such, a management plan that addresses threats to wolverine must be developed within three years of legal listing. However, limited information exists to guide conservation or mitigate human activities that affect wolverine. To address this knowledge gap we surveyed wolverine biologists, managers and local users for their perspectives on wolverine population status, threats, and recommended management actions. Participating scientists and resource managers believe climate change is the greatest threat to local wolverine followed closely by habitat loss and disturbance from recreationist. Changes in the duration and depth of the snowpack was identified as the single greatest threat to wolverines and the alteration of harvest quotas and use of harvest reserves as the most effect management tools. In contrast, local respondents, mostly trappers and indigenous people from the Yukon see wolverine populations as stable and trappers as good stewards of the resource. Threats identified by local people focus more on prey populations and habitat loss and were averse to changing access to public lands or trapping regulations. Threats to wolverine populations are perceived as limited to development and local in scope. Our surveys highlight a key difference in perceptions of threats and solutions to wolverine management. Both groups list climate change as a key threat but differ in the mechanism by which climate change will impact wolverine. Understanding the role of abiotic (snowpack and temperature) and biotic (predators and prey) factors is key to determining what habitat requirements and conservation actions will be most appropriate.

Darimont 1 hensonlh@gmail.com Anthropogenic and landscape drivers of population genetic structure in grizzly bears on the central coast of BC Large-scale patterns of genetic variation can enable investigation into how well landscapes – in the deep and recent past – have facilitated animal movement and mating. Among the potential drivers of population genetic structure, historical human activities are rarely considered. Additionally, the movements of large, wide-ranging carnivores are often thought to be influenced by only the most disruptive of landscape features. In collaboration with five First Nations, we genotyped 22 microsatellite loci from noninvasively collected hair samples of grizzly bears over a 23,500km2 area of the central coast of British Columbia. We used the population genetics software STRUCTURE to characterize patterns of genetic differentiation. Surprisingly, we identified three well-differentiated groups. To gain insight into the role of potential drivers, we created resistance surfaces using Circuitscape, which incorporated past and present human use and settlement patterns, in addition to disturbance and landscape barriers. We assessed the explanatory power of these surfaces using Commonality Analysis. Water barriers and the spatial demarcation of human language families contributed most to explained variation. The identification of differentiated subpopulations and the factors that mediate this differentiation not only provides insight into past and present ecological conditions but also management of populations into the future. 16
Jessen T.1,2 N. Ban3 , C. Darimont 1 University of Victoria, Victoria, BC & Raincoast Conservation Foundation Sydney BC, tjessen1213@gmail.com Contributions of Indigenous Knowledge to Wildlife Ecology and Evolution: synthesis, prospects, and guidance Incorporating diverse knowledge systems leads to richer understanding of wildlife ecology and evolution, providing scholarly and applied value. Here we synthesize the growing body of work on the contributions of Indigenous Knowledge (IK). IK is place-based knowledge accumulated intergenerationally within a cultural context, often augmented with contemporary observations and experiences. This potent source of information can provide insight into population trends, habitat use, species interactions, population genetic structure, and more. Such insight emerges from long periods of direct observation and interactions with wildlife (spanning generations) that offer new hypotheses and unique information transmitted through oral history, spatially-explicit experiences, field work, and interviews. We review the primary methods used to engage IK, highlighting complementarities and differences with science. Despite the value of IK to wildlife science, researchers often lack training and experience to engage with IK in a culturally-sensitive manner. Cultural sensitivity is warranted because of past and present harms scientists impose(d) on Indigenous peoples and the potential for IK to be subsumed inappropriately into western scientific- and management paradigms. Attending to these promises and pitfalls, we offer illustrative examples from the literature, emergent properties from our synthesis, and guiding principles to support respectful interaction between IK Holders and wildlife scientists.

Merrill 1 MSc Student, Royal Roads University, Victoria BC, lorinakeery@gmail.com Evaluating the impact of reintroduced bison in Banff National Park Plains bison have been absent from Banff National Park (BNP) since its establishment. Reintroducing bison to BNP is an important step to restore the full diversity of species and natural processes in the Park’s ecosystem. The reintroduction of a dominant ungulate is expected to have a significant impact on the ecosystem through grazing and physical disturbance. My research assessed what impact reintroduced bison had in the 18 ha soft-release pasture system. I examined a) bison diet in relation to forage availability b) forage selection patterns and c) how bison select for and use different landcover types. I also monitored the impact bison had on vegetation using a before-after control impact (BACI) experimental design. Data were collected in 2016 and 2017, before and after the bison were reintroduced. When bison grazed naturally, grasses consisted of 87% of their diet with forbs representing a minor component of their diet (0.4%). Consistent browsing on shrubs was observed throughout the year, comprising 12% of bison diet. Browsing consisted primarily of Salix spp (7%) with minimal browsing observed on other shrub species. The results of this study will help Parks Canada managers develop monitoring programs and anticipate bison grazing impacts when the bison are free roaming. 17
Kroc E.1, L. K. Blight, W. Cao 1 Research Associate, University of British Columbia, Vancouver BC, ed.kroc@ubc.ca The Urban Bird: Promoting and Protecting Urban Nesters, Migrants, and Residents Violet-green Swallows migrate from Central America to breed in the wood siding of city structures. White-crowned Sparrows winter in BC and come to nest in the bushes beside our bus stops. Great Blue Herons and Bald Eagles nest in our city parks, Pelagic and Double-crested Cormorants nest beneath our bridges, and Glaucous-winged Gulls live year-round and nest atop our rooftops. Whether they occur in native habitat or the city, birds and their nests are protected by law. Each of these examples (and others) speak to the need to develop ecologically responsible building codes, construction schedules, and city bylaws. There is also a need to educate both the general public and local governments about how our avian neighbours use our cities. We use recent and ongoing research in Vancouver and Victoria, to explore the urban life of these species and make recommendations about what can be done to protect and promote their urban populations while minimizing human-wildlife conflict. As some of these species face the loss of their traditional habitats (notably, many waterbirds of coastal southwest BC), the need to study and protect their habitats in the urban environment is an urgent one.

Boutin 1 Doctoral Candidate, University of Alberta, Edmonton, ctlamb@ualberta.ca Genetic tagging in the Anthropocene: scaling ecology from alleles to ecosystems. The Anthropocene is an era of marked human impact on the world. Quantifying these impacts has become central to understanding the dynamics of coupled human-natural systems, resource-dependent livelihoods, and biodiversity conservation. Ecologists are facing growing pressure to quantify the size, distribution, and trajectory of wild populations in a cost-effective and socially-acceptable manner. Genetic tagging, combined with modern computational and genetic analyses, is an under-utilized tool to meet this demand, especially for wide-ranging, elusive, sensitive, and low-density species. Genetic tagging studies are now revealing unprecedented insight into the mechanisms that control the density, trajectory, connectivity and patterns of human-wildlife conflict for populations over vast spatial scales. Here we outline the application of, and ecological inferences from, new analytical techniques applied to genetically-tagged individuals, contrast this approach with conventional methods, and describe how genetic tagging can be better applied to address outstanding questions in ecology. We provide example analyses using a long-term genetic tagging dataset of grizzly bears in the Canadian Rockies. The genetic tagging toolbox is a powerful and overlooked ensemble that ecologists and conservation biologists can leverage to generate evidence and meet the challenges of the Anthropocene.

Student, University of British Columbia Okanagan, sultanamajid@gmail.com The movement ecology of infection risk for California bighorn sheep (Oviscanadensiscalifornia) in the South Okanagan, British Columbia. 18
Parasites influence animal behavior, population dynamics, and ecosystem processes. Parasite transmission is tied to the host animal’s movement, which is influenced by changes in the landscape. In the Okanagan Valley of British Columbia, California bighorn sheep (Oviscanadensiscalifornia) populations have declined by 60% following an infestation of Psoroptisovis mites in 2011. The mites are transmitted through individuals and the environment, leading to debilitating skin diseases. Mite infection is currently contained to a sheep subpopulation in the west side of the valley due to landscape barriers, but transmission risk to the east subpopulation is a significant concern. We will be conducting two analyses: habitat connectivity and landscape change scenario simulation. Using GPS tracking data of 75 sheep from 2015 – 2019 (45 west- infected; 30 east-uninfected), we will compare habitat selection and identify areas of contact risk between infected and uninfected subpopulations. The habitat selection data will populate an agent-based model simulating the spread of mite infection under different landscape change scenarios: increased connectivity (i.e., wildlife overpass) and new infection point sources (i.e., domestic sheep operations). Understanding the link between connectivity and disease exposure will help wildlife managers design effective mitigation measures, critical for conserving sheep populations in the future.

Bishop 1 The University of British Columbia Okanagan, kmancuso88@gmail.com Migration and Overwintering Locations for Yellow-breasted Chats Breeding in the South Okanagan Valley of British Columbia. Western Yellow-breasted Chats (Icteriavirensauricollis) are a species at risk the northern limit of their breeding range in the dry interior of the south Okanagan Valley of British Columbia. This small population is listed as Endangered in Canada due to historic loss and fragmentation of their lowland riparian nesting habitat. To further understand the movement patterns of this population, we deployed individual tracking devices on the backs of adult male birds to determine their migration route and overwintering areas. Results to date show British Columbia chats follow the Pacific flyway enroute to wintering areas in western Mexico. Our project will compare these results with those from chats breeding in northern Calififrnia. Additional research in progress on this population (and more southerly populations) include an examination of stress levels and heavy metal contamination. A better understanding of the range-wide ecology and potential threats to this Endangered peripheral breeding population will help guide conservation efforts to ensure long-term population viability.

Routledge 1 Hemmera Burnaby, BC.tstclair@hemmera.com Presence of Little Brown Myotis(Myotislucifugus) Positively Associated with Trees and Negatively Associated with Artificial Light within Waterfront Sites in Metro Vancouver. Anthropogenic activities can influence bat presence and distribution. We assessed the influence of human development and activity levels (artificial light and noise) on little brown myotis (Myotislucifugus), a bat species listed as Endangered under the Canadian Species at Risk Act. We surveyed 14 sites adjacent to freshwater (Fraser River) and marine (Burrard Inlet) environments within Metro Vancouver to examine these factors. We selected sites along a gradient of habitat disturbance 19
and anthropogenic activity levels (e.g., modified vegetation, light, noise). Time-constrained (15 minute) nocturnal surveys were conducted at each site using an Echo Meter Touch microphone and sound and light meters over three nights in each of July and September 2016. Little brown myotis was the most prevalent and widely distributed bat across the study area with detections recorded at 11/14 sites (79%). Stepwise regression models (GLM) found little brown myotis presence was positively associated with trees (>20 cm DBH) and negatively associated with ambient light.Little brown myotis was detected more often within fresh water than marine sites and was detected more frequently during July surveys (i.e., maternity period) as compared to September(i.e., migration/pre-hibernation period). Noise levels were not significantly related to the presence of little brown myotis. Meineke J.K.1, K. E. Hodges, and F. I. Doyle 1 University of British Columbia Okanagan.jennifer.meineke@ubc.ca Effects of biosolids on vole population ecology and the raptor and owl community. Grasslands around the world are becoming degraded due to human causes. In North America’s interior Pacific Northwest, more than 90% of semi-arid grasslands are in need of restoration. In British Columbia, grasslands cover only about 1% of the landmass, yet 20% of species listed as “at risk” of extinction in British Columbia occupy grasslands. Grassland restoration is therefore important to managing imperiled species. Biosolids (post-treatment sewage) are being used to restore grasslands in some areas. These grasslands appear to support high densities of insects and small mammal prey, potentially enhancing predator populations of owls and raptors. To further this research, I will be studying vole populations at the OK Ranch, a cattle ranch near Clinton, British Columbia. I will quantify differences in vole populations on untreated pastures and pastures with biosolids applied. I will also study raptor and owl populations at the ranch, specifically comparing the diets of different species in a biosolids-influenced ecosystem. This research will expand our knowledge about how biosolids can be used in ecological restoration and wildlife conservation. Through this project, I am hoping to discover if biosolids can be used to help restore wildlife populations on degraded grasslands. Mihalik I.1, A. W. Bateman, and C. T. Darimont 1 ilonammillie@gmail.com Big game hunters pay more to target larger-bodied carnivores: insight from costly signalling theory. Human hunters often target species that require resource investment disproportionate to associated nutritional rewards. Costly signalling theory may provide an explanation if human hunters target species that impose high costs, thereby signalling to potential mates or competitors the underlying physical and cognitive qualities that permit the hunters to absorb such costly behaviour. If costly signalling is relevant to contemporary hunters, and if prices for guided hunts reflect desirability, we would expect hunters to pay more to hunt taxa with higher associated costs (e.g. high failure risk, risk of injury). Accordingly, we hypothesized that prices would be higher for taxa that are larger-bodied, rarer, carnivorous, or described as dangerous or difficult to hunt. In a data set on 721 guided hunts for fifteen North American big-game species, prices listed on the internet increased with body size (from approximately $550 USD/day to $1800 USD/day across the observed range of body mass) in carnivores. We did not find a signal of rarity or perceived danger or difficulty. If larger-bodied carnivores are generally more desirable 20
to hunters due to perceived benefits of costly signalling, then conservation and management strategies should consider not only the ecology of the hunted but also the motivations of hunters.

Garth.Mowat@gov.bc.ca The sustainability of wolverine trapping mortality in southern Canada There is considerable conservation concern for wolverines throughout their range in North America. Previous researchers used population models and observed estimates of survival and reproduction to infer that current trapping rates strongly limit population growth, except perhaps in the far north where kill rates appear lower. Assessing the sustainability of trapping empirically requires both demographic and abundance data which are expensive to acquire and hence usually only achievable for small populations which makes generalization risky. We surveyed wolverines over a large area of southern British Columbia (BC) and Alberta and used spatial capture-recapture models (secr) to estimate density and then calculated trapping kill rates using provincial fur harvest data. Wolverine density averaged2/1000 km2 and was positively related to spring snow cover and negatively related to road density. Observed annual trapping mortality was >8.4%/year. This level of mortality is unlikely to be sustainable except in rare cased where movement rates are high among sub-populations and sizable un- trapped refuges exist. Our results suggest current conservation risk to wolverine is high because our study area was fragmented by both human and natural barriers and few large refuges exist. We recommend wolverine mortality be reduced by at least 50% throughout southern BC and Alberta to reduce conservation risk and promote population recovery. Uncertainty in the trapping data created considerable conservation risk and we suggest BC and Alberta adopt a more certain mortality recording system for this species. Naidoo R.1 and C. Burton 1 World Wildlife Fund and University of British Columbia,Robin.Naidoo@wwfus.org Recreational impacts on wildlife in the South Chilcotin Mountains, BC The South Chilcotin Mountains Provincial Park and adjacent areas are notable for their diversity of large wildlife species, including predators such as grizzly bear, wolverine, and cougar, and large ungulates such as moose, mule deer, and mountain goat. Industrial activities like logging and mining have long operated on the landscape, while more recently, recreational activities, particularly mountain biking, have increased. The relative impacts of industrial versus recreational activities remain largely unknown, which hinders development of management plans that account for cumulative impacts on wildlife. Here, we use camera traps (n=61) and statistical analyses to untangle the relative contributions of land- use/land cover and recreational activities on several large wildlife species in the South Chilcotins. Cameras operated from May-September 2018, recording use of trails and logging roads by wildlife and people. We developed spatial data layers that reflected land-use and habitat covariates at and around camera traps. We used occupancy analyses to show that some species, such as grizzly bears, were more sensitive to human recreational activities than to land-use type, while others, such as mule deer and 21
black bear, showed the opposite pattern. Our results can help park and resource managers balance the needs of people and wildlife in this region. Proctor, M.1, W. Kasworm, G.MacHutchon, G.Sanders, J.

Servheen Re-establishing functional connectivity in a threatened BC grizzly bear population 1 Trans-border Grizzly Bear Project, PO Box 606 Kalso, BC, V0G 1M0, CANADA, mproctor@neteidea.com Recovering threatened wildlife populations and reversing population fragmentation are 2 conservation goals that are pressing but elusive. We have been researching conservation issues and implementing a comprehensive program to recover several small isolated and threatened populations of grizzly bears for over a decade in the trans-border region of southern Canada and NW USA. We found conflict-related mortality significantly contributed to their threatened status by causing population declines, fragmentation, and decreased habitat effectiveness. Our conservation program included strategic private land purchases to reduce human densities in wildlife corridors, efforts to secure bear attractants, and non-lethal management of conflict bears and more. We radio collar and use non-lethal management on potential conflict bears and have a ~84% success rate on females. We identified the most important backcountry foraging habitats for protection with motorized access controls to reduce conflicts and mortality and provide habitat security to reproductive females. The composite effects of working across these arenas has resulted in a significant reduction in human-caused mortality and increased connectivity, habitat effectiveness, and reproduction resulting in an improved conservation status of several now-recovering threatened populations. Several challenges remain including a plethora of offspring from females living adjacent to agricultural areas.

Wonder no more. I will go through the criteria and method that has been adopted by the B.C. Conservation Data Centre to assess species and ecosystems in B.C.. This method was developed through NatureServe and is used across North and Latin America. We have been using versions in B.C. since 1991 and the latest iteration since 2012. It is also used to complete the General Status assessments across Canada. There are methodological and criteria overlaps with IUCN and COSEWIC, the other big assessment names that will be touched on. A complete assessment relies on data from many sources that is as current as possible. Having the connections open and identified with people working on the ground in many capacities is important.

Recent technological innovations, particularly widespread access to high-resolution cameras and online species databases like eBird and iNaturalist, have facilitated the generation of massive open data collections. The increasing popularity of these platforms among recreational users gives them potential to be an effective tool for wildlife education, outreach, and data collection. The scientific value of citizen-generated data has been a divisive topic of discussion, but ongoing developments in data validation and management continue to advance citizen-science as an inclusive and innovative approach to wildlife data and community-driven questions. This approach necessitates a discussion on collection methods, data quality, and wildlife ethics. St. Clair C.T.1, J. Hobbs, J. Randall 1 Hemmera,Burnaby, BC.tstclair@hemmera.com Challenges and Insights in Assessing Long-term Population Trends of Coastal Western Screech-owl (Megascopskennicottiikennicottii). Monitoring population trends is challenging and requires cooperation among stake-holders, particularly for rare and difficult to detect species. The coastal subspecies of western screech owl (Megascopskennicottii[WSOW]) appeared to be declining in British Columbia; however, lacking a long- term monitoring plan, this was difficult to confirm. We compiled existing records for WSOW from government, industry, and independently funded efforts and used occupancy modeling to assess historical population trends and provide recommendations for long-term monitoring. Results suggest that WSOW populations had declined substantially since 2000, particularly between 2005 and 2008. Estimates of current occupancy and detection probability within suitable habitat were low (10-20% and 30-40%, respectively). Consequently, we determined that the effort necessary to detect long-term trends was not likely feasible. Alternative objectives for future monitoring were recommended: modest survey efforts where historical data is available for comparison; surveys in habitats with the potential to support healthier WSOW populations (e.g., Hypermaritime, low productivity, mature forests). Follow-up surveys within such habitat in northern and western Vancouver Island found much higher occupancy rates (36-92%: MFLNRO, B. Schroeder, G. Monty). These results provide preliminary indications that, in some areas, healthier populations of WSOW may persist and provide new opportunities for long-term monitoring within BC. Sunter, E.J.1 and A.T.
