The use of highway crossings to maintain landscape connectivity for moose and roe deer

Increasingly wildlife managers and land managers are challenged to maintain the viability and connectivity among large mammal populations. Thus, it is important that effective wildlife crossings and conventional road crossings are identified and optimized with respect to construction cost, facilitation of ungulate movements, and ability to reduce wildlife-vehicle collisions. Previous studies have evaluated the importance of structure design and size for many ungulate species, but few studies involved moose (Alces alces) which is the target species for most large ungulate mitigations in Sweden. We used infrared remote cameras, track count surveys, and GPS telemetry to monitor the use of wildlife crossings and conventional road passages by moose and roe deer (Capreolus capreolus). Given the continued changes that will occur in Sweden due to human development and infrastructure, we suggest that the construction of wildlife crossings along fenced roads are an important tool for traffic safety and to maintain meta-population dynamics across otherwise isolated areas (A).
