EDM International, Inc. (EDM) is an employee-owned corporation with a three-decade reputation for excellence. EDM’s Environmental Services Group is a team of wildlife biologists, avian specialists, soil scientists, hydrologists, regulatory specialists and GIS experts. EDM works collaboratively across disciplines to develop practical, science-based solutions to high-profile environmental challenges on behalf of electric utilities, extractive industries, government agencies and non-governmental organizations. EDM is internationally known for research and consultation on avian electrocution, avian collision and animal-caused outages. EDM’s key to success is its team members, who are chosen for their unique and complementary skills and who conduct their work with passion, creativity and integrity.
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.
EDM staff is experienced with the National Environmental Policy Act (NEPA) and complex third-party, multi-agency permitting and compliance projects. EDM specializes in the practical implementation of the Endangered Species Act (ESA), the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA). EDM offers environmental clearances prior to construction, environmental compliance monitoring services and turnkey stormwater solutions for projects resulting in substantial surface disturbance. EDM excels at proactive communication and facilitates collaborative solutions addressing the needs of permit applicants, land managers and regulatory agencies. EDM conducts regulatory trainings to help clients understand and comply with the regulatory framework, while maximizing their own professional effectiveness.
Findings are disseminated through peer-reviewed papers, conference presentations, reports, monograph contributions and DVDs, as permissible under the terms of our partner and licensing agreements. EDM provides consulting on study design, data collection protocols and statistical analysis and has developed a number of commercially successful products, both independently and with industry partners.
The Bird Strike Indicator (BSI), developed by EDM, is an automated monitoring tool that detects and records bird strikes on overhead wires or guy wires, and transmits real time data to remote desktops. BSIs have been deployed throughout the U.S. (including Alaska) and in Europe, Africa and the Pacific Islands. Utility companies, permitting agencies, and industry researchers have used the BSI to identify high risk power line segments, evaluate collision risks to sensitive bird species, and determine the effectiveness of line marking devices. BSIs have been used to determine the need — or lack thereof — for both proactive and reactive line marking. The BSI recently was specified as NEPA-required mitigation for a new, high-profile transmission line bisecting a critical migration corridor.
In order to address avian fatalities, many utilities now check equipment for potential areas that may pose hazards for birds. A common method is to look under power lines for dead birds. Identifying species for these fatalities is important for a number of reasons. When decomposed carcasses, bone pieces, feathers or pellets are found under electrical structures, it can be difficult to identify the species. This guide provides a resource for identifying partial remains of selected avian species.
In partnership with PIER, EDM has developed and made available a photographic guide to identifying the remains of selected species of raptors.
Video: Raptors at Risk EDM’s role is often that of educator through serving as host or participant in workshops on animal interactions with electric utility infrastructure. Educational projects include the development of an interactive web site on raptor electrocutions for the California Energy Commission, http://bems.edmlink.com, and a product encyclopedia of mitigating products for the Electric Power Research Institute (EPRI). EDM co-produced the award winning video/DVD “Raptors at Risk,” as well as a photographic field guide for identifying raptor remains.

BSI is an automated, cost-effective tool for continuous detection and recording of bird collisions on power and communication lines.
The Bird Strike Indicator (BSI) is an automated vibration-sensing and recording tool designed to detect bird strikes on aerial cables such as power lines and guy wires. It affordably provides utilities the ability to identify the most dangerous line segments and determine the effectiveness of line marking devices. The BSI uses accelerometers to record stress waves and vibrations caused by a bird strike. The BSI sensors are installed on the monitored wires and transmit strike activity wirelessly to a nearby base station where the data is recorded.
