Declaration of Committee Name: Laura Kroesen Degree: Master of Science (Biological Sciences) Thesis title: Temporal patterns and behavioural states of mountain goat (Oreamnos americanus) movements to hotspots in the Rocky Mountains Committee: Chair: Leithen M’Gonigle Assistant Professor, Biological Sciences David Hik Supervisor Professor, Biological Sciences Seth Cherry Committee Member Ecologist Parks Canada David Green Committee Member Professor, Biological Sciences John Reynolds Examiner Professor, Biological Sciences ii Ethics Statement iii Abstract Concentrated resources, or hotspots, can influence movement behaviour of many species. I studied the movement ecology of two groups of mountain goats (Oreamnos americanus) and their relationship with hotspots in the Canadian Rocky Mountains. First, I investigated fidelity to two roadside mineral licks. Movement patterns to mineral licks were documented over several temporal scales and I found that mountain goats have strong trans-generational, seasonal and daily movements to these mineral licks. Second, I investigated movements to foraging, travelling, and bedding areas in summer ranges, using hidden Markov models (HMMs) and predicted behavioural states. These behavioural states were ground validated and the results showed that HMMs can be used as a proxy for habitat hotspots. Understanding how animals adjust their movement behaviour to hotspots can provide valuable information for the management of these critical habitat features and the wider conservation of mountain goats. Keywords: Mountain goats, Oreamnos americanus, habitat hotspot, mineral lick, temporal patterns, hidden Markov models, Rocky Mountains iv Dedication This thesis is dedicated to the mountains and all the creatures who make a living amongst the rock and ice. “Mountains are the closest our planet reaches towards the heavens. The purest air, the purest water, and the purest light on earth are found amidst these uplifted forms. They are the source of awesome natural power, shaping winds, weather and the rivers that flow across the land. And they are the home of very special living creatures… one large animal that belongs almost entirely to the realm of towering rock and unmelting snow. Pressing hard against the upper limit of life’s possibilities, it exists higher and steeper through the year than any other big beast. It is possibly the best and most complete mountaineer that ever existed on any continent: the mountain goat.” Douglas H. Chadwick – A beast the color of winter 2002 v Acknowledgements First and foremost, I would like to thank my two supervisors Dr. David Hik and Dr. Seth Cherry for their support over the past two years.

To prevent the issuance of misleading information, persons wishing to quote from this report, to cite it in bibliographies or to use it in any other form must first obtain permission from the Executive Director of the Wildlife Management Branch, Fish and Wildlife Division and / or its regional representatives within the Southern Rockies Area. ACKNOWLEDGEMENTS The 2009 WMU 402 goat survey was navigated by Greg Hale (FW), while Mike Jokinen (ACA), Jon Jorgenson (FW) and Rob Watt (Parks Canada‐Waterton) participated as observers. The aircraft was chartered from Bighorn Helicopters with Greg Goodison as the pilot. ABSTRACT An aerial survey to monitor the status of the mountain goat population in Wildlife Management Unit (WMU) 402 was conducted on July 11th, 12th and 15th, 2009. Survey objectives included the collection of herd distribution, herd composition and total goat numbers. All mountain complexes associated with the WMU 402 goat survey received detailed aerial coverage during the survey. The WMU 402 survey area is the northern portion of Goat Management Area (GMA)–A, and currently does not have a designated goat hunting area. A total of 186 mountain goats (119 adults, 44 kids and 23 yearlings) were observed during the survey. Kid and yearling ratios per 100 adults were 37 and 19 respectively. Sixty nine goats were observed on the Alberta side of the Continental Divide while 41 goats were observed in British Columbia.

Kicking Horse Canyon mountain goats 11 Executive summary Upgrades to portions of the Trans Canada Highway (TCH; Highway 1) are being conducted which will include reconstruction of two bridges and their approaches in the Kicking Horse Canyon east of Golden, B.C. Improvements and upgrades to this section of the TCH are required to improve the efficiency and safety of vehicular travel. The objectives of this study were to identify potential impacts to mountain goat (Oreamnos americanus) use of and access to the bluffs adjacent to the two bridges; to assess these impacts; and to recommend potential mitigation required to bridge and approach design and construction that will minimize impacts to the goats. Bluffs adjacent to these bridges were reported to contain mineral licks, which are seasonally of high importance to resident goat populations. In addition, we present recommendations for revegetation of surplus material disposal sites for forage values of various recommended species. The existing alignment of the TCH crosses from the north side of the canyon to the south side at the Yoho Bridge (5-Mile Bridge; segment 990, km 9.5). The highway recrosses back to the north side 4.6 km further up the canyon at the Park Bridge (10-Mile Bridge; segment990, km 14.1).

    Wildlife Corridors in the Lake Louise Area, Alberta: A Multi-Scale, Multi-Species Management Strategy Final Report Prepared for: Alan Dibb, Wildlife Specialist Kootenay, Yoho, Lake Louise District Parks Canada Box 220 Radium Hot Springs, BC V0A 1M0 Prepared by: Marie Tremblay 5704 Lakeview Drive S.W. Calgary, AB T3E 5S4 August 2001 PREFACE This report was prepared under the terms of Parks Canada contract #KKP 2064. The views expressed are those of the author and do not necessarily reflect the policies of Parks Canada. This document may be cited as: Tremblay, M. 2001. Wildlife Corridors in the Lake Louise Area, Alberta: A Multi-Scale, Multi-Species Management Strategy. Prepared for Parks Canada. 168pp. i EXECUTIVE SUMMARY BACKGROUND Habitat fragmentation is a central issue in the Lake Louise area due to the presence of a naturally fragmented landscape coupled with high levels of human activity, a situation that is believed to be constraining the movements of wildlife in the area. Human influences in the Lake Louise area include four nodes of visitor activity (the Hamlet of Lake Louise, the Upper Lake area, the Lake Louise ski area, and the Moraine Lake area), two major transportation corridors (the Trans-Canada Highway and the Canadian Pacific Railway), several high volume secondary roads, a dense network of popular hiking trails, and dispersed human activity such as off-trail hiking and snowshoeing. Although a variety of studies have been carried out to further our understanding of wildlife habitat use and movements within BNP, there has been no attempt to synthesize information from multiple sources into a single consideration of wildlife corridors specifically for the Lake Louise area.
