Pollinators and other insects are important for agricultural production and for their ability to provide food to other wildlife, such as turkey, whitetail deer, songbirds and insect-eating bats. That’s why we plant pollinator-friendly native vegetation installations where feasible. We've created 100,000 acres of pollinator playground for honeybees and Monarch butterflies and Ameren is a member of several organizations working to support pollinator habitats including Missourians for Monarchs and Illinois Monarch Project.
Ameren developed a Biodiversity Policy to guide our operational efforts to reduce, minimize or avoid impacts on biodiversity as we develop infrastructure or conduct operations.
- Assess and prevent or reduce impacts on biodiversity from company actions and ongoing operations, wherever possible.
- Promote, support and participate in wildlife conservation initiatives and programs that are responsive to and consistent with our business activities.
- Continue to implement habitat mitigation measures or enhancements associated with projects as we improve and modernize our electric and natural gas businesses.
- Continue to establish habitat-friendly areas on Ameren-owned properties where feasible.
- Utilize pollinator-supportive and native plants as part of construction, maintenance and restoration activities, and in landscaping at offices, where practical.
- Create awareness and understanding of biodiversity by engaging with co-workers and stakeholders – including the communities and customers we serve, government agencies, universities and other organizations – when planning, building and operating our energy infrastructure.
When it comes to supporting biodiversity by providing for native species, we focus on four key areas throughout our service territory: pollinators, birds, bats, and big river ecology.
In partnership with private landowners, conservation organizations, research and transportation entities, Ameren has created many acres of habitat each year as a participant in the Monarch Butterfly Candidate Conservation Agreement with Assurances (CCAA) For instance, in Creve Coeur, Missouri, Ameren converted almost four acres of turf into pollinator-friendly vegetation in partnership with the Saint Louis Zoo and with a native seed donation from Turfmasters Inc. Quail Forever provided consultation on maintenance and invasive species control work for the project as well. We have several similar projects throughout the greater St. Louis region and throughout Illinois.
Just as Ameren's rights of way and substations actively undergo integrated vegetation management to maintain safety and reliability, our pollinator-friendly plantings are actively maintained as well. For example, new native installations will undergo several years of establishment work on the front end, such as high mowing to control weeds, invasive species removal and overseeding as necessary. Established native plantings will then ideally be high mowed once annually during the dormant season. Already established plantings may require periodic restoration to preserve the integrity of these projects should they become overrun with invasive species or lose biodiversity, so there may be times when these projects are mowed during the growing season.
Ameren currently works with several reputable contractors to install and maintain pollinator-friendly projects on Ameren property. There may be times when Ameren must impact a native planting project on its property to repair or upgrade assets to continue providing power to our customers. Ameren will make every feasible effort to restore the affected area with native species or relocate the native planting to a more suitable location.
Ameren is also a member of several organizations working to support pollinator habitats:
- Power in Pollinators Initiative: Ameren is a founding member of the Electric Power Research Institute's initiative to help utilities research and understand ways their actions can not only minimize the impact on pollinators but also support them.
- Missourians for Monarchs
- Illinois Monarch Project
- UIC Rights of Way as Habitat Working Group
- Forest ReLeaf of Missouri
Ameren has an Avian Protection Plan (APP) in place, which was developed by an internationally renowned consultant specializing in assessing impacts to avian populations. Current best practices regarding the APP are applied across Ameren's assets throughout Missouri and Illinois. Some elements of the APP are:
- Proactive retrofits of facilities at potential highest risk of avian incidents
- Retrofits at facilities wherever incidents may occur
- Development of avian-safe standards for transmission and distribution construction
- Training of line crews, supervisors and outside contractors
- Reporting incidents to the U.S. Fish and Wildlife Service
- Investing in avian enhancements, such as support of bird rehabilitation centers like the World Bird Sanctuary and Illinois Raptor Center
In addition, Ameren initiated a territory-wide review of over 100 substations in Ameren Illinois to assess their current level of avian-safe design. We installed 92,000 avian-safe distribution poles and 180,000 protective covers on energized equipment and retrofitted 1,400 structures, resulting in reduced avian-related incidents at substations. The program has become a model of best practices for other utilities in the region.
See below for additional wildlife conservation projects that help protect bird populations in Missouri and Illinois:
- Flight Diverter Installation: Ameren Missouri installed flight diverters on transmission lines within the Riverlands Migratory Bird Sanctuary, adjacent to the Mississippi River near Sioux Energy Center, among other locations, to prevent collisions between trumpeter swans and high-voltage lines.
- Illinois Raptor Center: Ameren Illinois supported the construction of 36 raptor cages to house educational raptors at the center in Decatur, Illinois. The cages will allow public access to view raptors and learn more about raptor awareness and power line safety, and provide a safe place for injured raptors until they build enough strength to be released.
- Reflector Installation: Ameren installs reflectors and protective coverings on power lines where birds like to perch to protect them from contact with high-voltage lines.
- TreeHouse Wildlife Center: Ameren Illinois supported the construction of a 96-foot-long flight cage with over 200 feet of safe flight space for injured raptors to redevelop strength and skills during the final stages of rehabilitation.
- World Bird Sanctuary: Ameren continues to partner with the World Bird Sanctuary by supporting suitable habitats for all bird species.
- Native Vegetation Restoration: Areas planted and managed for native vegetation within our owned or managed properties and rights of ways provide beneficial habitat for a variety of bird species for foraging, nesting, and stopover cover during migration.
Nearly 50% of the known hibernating population of the federally endangered Indiana Bat (Myotis sodalist) occurs within Ameren’s combined service territories, along with many other species of cave-dependent bats. Ameren carefully evaluates proposed projects for their potential to impact the habitats these species rely upon.
- Bat Conservation Plans: Ameren has developed bird and bat conservation plans for each of our recently acquired wind energy facilities. We are in the final stages of developing a Habitat Conservation Plan for the Indiana bat, northern long-eared bat, and little brown bat for the High Prairie Wind Energy Center in Schuyler and Adair counties in Missouri. This plan is being developed in support of an Incidental Take Permit for the three bat species. It will provide clear operational guidelines to protect the covered species, as well as monitor and reduce the impact on all bat species living within or migrating through the facility.
- Missouri Bat Census: Ameren provides financial support for the private stewardship of cave and karst resources in Missouri. The Missouri Bat Census works with private landowners and managers of properties with caves to protect the caves, cave-dwelling species, and geological formations within them from damage and vandalism. Where necessary, the group helps install wildlife-friendly gates across their portals, allowing bats and other wildlife access while keeping unauthorized people out.
- Research: Ameren is actively engaged in industry-leading research with the Electric Power Research Institute’s (EPRI) Endangered and At-Risk Species Research Program, which includes bats.
At our steam-electric and hydroelectric generating facilities, Ameren complies with the requirements of Section 316 of the Clean Water Act, our NPDES operating permits and our FERC hydroelectric operating licenses. We have qualified, professional fisheries scientists on staff to guide the company's monitoring of fisheries species. When constructing new assets, we proactively identify water features within a project footprint so we can avoid and/or minimize impacts to those resources where feasible. When required, we obtain the necessary permits under the Clean Water Act, including sections 401, 402 and 404, and follow all mitigation and permit conditions to minimize impacts to water quality. By using native vegetation to restore areas disturbed by the construction and operation of our sites, Ameren helps manage erosion and stormwater quantity and quality within the watersheds near our operations.
- Aquatic Resource Protection Research Program: Ameren is an active funder and participant in the Electric Power Research Institute's (EPRI) research program. EPRI works to understand and develop cutting-edge technologies that protect fish communities and aquatic ecosystems from the impacts of utility operations.
- Osage Energy Center Initiatives:
- The Lower Osage River Protection and Enhancement Program, part of Ameren's operating license, provides funding to the U.S. Fish & Wildlife Service to implement a tailwater management plan on the lower Osage River downstream of Bagnell Dam. This program, in consultation with the Missouri Department of Conservation, is restoring and reconnecting the backchannel river habitat, and addressing the impacts of bank erosion on those habitats. It has successfully propagated and stocked over 12,000 federally endangered pink mucket mussels - the largest known population of this species throughout its range.
- A fish barrier net protects large fish from the turbines in the dam, including species of conservation concern such as paddlefish.
- High-efficiency turbines directly mix oxygenated air into the water drawn through the turbines. Combined with closely monitoring downstream oxygen and total dissolved gas levels within the Lower Osage River in real time, this technology has improved the habitat in the tailwaters of Bagnell Dam.
- Lower East Fork Black River Sediment Augmentation Plan: As part of Ameren's operating license for the Taum Sauk Energy Center, Ameren is collaborating with the Missouri Department of Conservation and the U.S. Geological Survey to conduct a pilot study examining the effectiveness of seeding river sediments into the Lower East Fork Black River to restore natural sediment transport dynamics. The goal is for this effort to ultimately lead to a natural enhancement of stream habitat, as a more natural sediment transport dynamic is restored to the river system.
- Missouri River Recovery and Implementation Committee (MRRIC): Ameren staff actively participate in this broad coalition of stakeholders composed of representatives from natural resource and environmental entities, industry, the barging community, flood protection agencies, Native American Tribes, irrigation managers, and local government representatives. Members of MRRIC advise the U.S. Army Corps of Engineers as they implement a congressionally mandated restoration plan for the Missouri River.
