Wolverines are key scavengers in boreal and alpine ecosystems. Their role in nutrient cycling and carcass processing has important ecosystem and welfare implications.
Understanding wolverine scavenging ecology is important for conservation planning because carcass availability — determined by ungulate populations, predator presence, and winter severity — directly affects wolverine welfare through food security. Individual wolverines that cannot access sufficient carcasses face nutritional stress, reduced reproductive success, and potentially increased mortality. Competition with recolonizing wolves for carcasses in areas of wolf recovery has welfare implications for wolverine populations. Conservation programs that maintain prey populations through hunting management and predator coexistence create the conditions for wolverine food security. Snowmobile access to remote backcountry reduces natural wolverine foraging by disturbing feeding at carcaches and increasing energy costs of competition.
