    Abstract
    "This thesis was an interdisciplinary investigation with the goal of balancing the conservation of wildlife habitat with road access for subsistence hunting in Yakutat, Alaska. The problem posed by land managers and subsistence moose hunters revolved around the use of off-highway vehicles (OHVs; e.g. 'four-wheelers') for subsistence moose hunting and the potential disturbance OHVs have on moose. This complex social-ecological problem is becoming an increasingly common management dilemma faced by rural mixed cash-subsistence communities across the Circumpolar North. I addressed this problem in two chapters with a combination of methods from wildlife ecology, landscape modeling, subsistence land-use, and scenario planning. The data used for analysis in Chapter 1 was derived from a three-year moose GPS-collar dataset, remote sensing imagery, and mapped routes. I modeled moose distribution with multi-scale, seasonal and sex-specific resource selection functions in a GIS. The best-fit models suggested female moose were displaced by OHV routes. Male moose were displaced by routes or areas where routes were in close proximity to primary forage. A combined pattern of route avoidance was quantified beyond approximately 1 km of total vehicle travel/km²/day. Chapter 2 describes the application of distribution models from Chapter 1 to a social-ecological assessment of route closures. Meetings with land managers and moose hunters were conducted to identify their respective values and management goals. Then I evaluated the effect of four road closure scenarios on moose habitat and hunting access. A measure of hunting access was evaluated with interviews about hunter land-use patterns, as well as the mapping of harvest areas in a GIS. The results of the scenario evaluation showed the spatial arrangement of routes influenced the total amount of high probability moose habitat and access to preferred harvest areas. A balance in the conservation of wildlife habitat and the maintenance of hunting access may be found in the closure of routes through valuable moose habitat and the spatial arrangement of future routes around valuable moose habitat, within reach of important harvest areas. The results of the analysis and interdisciplinary approach may prove useful to land managers who must evaluate the trade-offs between wildlife habitat conservation and the increasing use of motorized access for contemporary subsistence hunting practices"--Leaf iii
