Avian Protection, Assessment & Mitigation

EDM has developed over 110 Avian Protection Plans (APPs) for small and large electric utilities, mining companies, oil and gas operators and federal agencies, throughout the U.S. and abroad. APPs and Avian Risk Assessments (ARAs) provide a roadmap for managing avian and wildlife interactions with power lines, substations and other aboveground structures such as mining/oil and gas infrastructure, communication towers and wind facilities. Clients report that EDM APPs improve system reliability, public relations and regulatory compliance; agencies reviewing the APPs describe them as exemplary. EDM’s ARAs and mitigation recommendations are the industry gold standard.

Featured Project

EDM developed an APP and ARA for a large investor-owned utility with over 20,000 miles of distribution and transmission lines across a major metropolitan region with globally important bird habitat. A GIS-based analysis of bird use, habitat and infrastructure data identified target survey areas. Field biologists assessed dozens of avian and power line variables to determine avian electrocution and collision risk; for each hazardous structure or line span, EDM assigned a retrofit priority and developed a retrofitting approach. The deliverables provided short- and long-term planning tools for reducing avian risk and improving system reliability. Updated construction standards and training modules were developed to ensure the plans were fully implemented and reliability and conservation goals were achieved. Tailored communications materials were developed to facilitate company outreach among customers, regulators and employees.
