Construction Guidelines for Wildlife Fencing and Associated Escape and Lateral Access Control Measures
This report describes the current state of knowledge and practice regarding the design, implementation and maintenance of wildlife fencing and associated escape and lateral access control measures. The state of knowledge and practice was summarized through a literature review (Chapter 2) and a survey among practitioners and other people who work with wildlife fencing and associated mitigation measures (Chapter 3). The main function of wildlife fencing is to keep wildlife off the highway, but wildlife fencing also helps funnel wildlife to safe crossing opportunities (at-grade, underpasses or overpasses). It is considered good practice to not increase the barrier effect of roads and traffic for wildlife without also providing for safe and effective crossing opportunities for wildlife. Therefore the authors of this report suggest to always combine wildlife fencing with safe crossing opportunities for wildlife. Based on cost-benefit analyses (Chapter 4), the authors of this report suggest that mitigated road sections for large mammals should perhaps be at least 3-5 km long, if the objective is to keep the average costs per kilometer mitigated road to a minimum. Shorter mitigated road sections have relatively high costs per kilometer of road. The authors of this report provide recommendations based on the current knowledge and experience of researchers and practitioners, and identify the most pressing research questions related to wildlife fencing and associated measures (Chapter 5 and 6).
