Bat Survey & Ecological Consulting Services



Volant EcoServices serves clients across the eastern United States, including Ohio, Pennsylvania, Kentucky, West Virginia, and Indiana. We partner with clients to deliver expert environmental consulting that supports project goals, regulatory compliance, and responsible land management. Volant offers a focused range of services—including bat surveys, environmental assessments, and forest inventories—designed to meet agency requirements and move projects forward. Our team brings decades of field experience and scientific training to every project, helping clients navigate environmental regulations while advancing practical, conservation-minded outcomes.

Volant EcoServices conducts bat surveys for state and federally listed bat species including the Indiana bat (Myotis sodalis), northern long-eared bat (Myotis septentrionalis), and tricolored bat (Perimyotis subflavus) across Ohio, Pennsylvania, Kentucky, West Virginia, Indiana, and the broader eastern United States. Our surveys include presence/probable absence mist-netting, acoustic monitoring, and habitat assessments conducted in accordance with current USFWS bat survey guidelines and ESA Section 7 consultation requirements.

Volant conducts potential bat hibernaculum surveys to evaluate caves, mines, rock features, infrastructure, and other underground or subsurface structures that may serve as winter habitat for listed bat species. Surveys follow the most current U.S. Fish and Wildlife Service range-wide guidelines and are designed to support regulatory compliance and informed project planning.


Our biologists assess habitat suitability through field inspections, documentation of bat sign, and measurement of environmental conditions that influence hibernation. When appropriate, surveys are coordinated with resource agencies and conducted during the fall/winter/spring seasons to minimize disturbance and ensure defensible results.



These evaluations help determine whether sensitive overwintering habitat occurs near a project and whether consultation, avoidance measures, or mitigation may be required. By integrating hibernaculum assessments with active-season surveys, Volant provides a complete, seasonally informed understanding of bat use to help clients move forward responsibly and efficiently.

Accurate species identification is the foundation of defensible bat survey results. Volant EcoServices provides professional acoustic data vetting services, manually reviewing ultrasonic bat call recordings using USFWS-approved software and the expertise of federally permitted biologists. Unlike automated identification alone, our manual vetting process ensures that detections of Indiana bat (Myotis sodalis), northern long-eared bat (Myotis septentrionalis), tricolored bat (Perimyotis subflavus), and other species are verified to the highest standard of scientific rigor.


Our biologists have completed multiple acoustic identification training workshops and maintain current knowledge of bat call libraries and detection best practices. We vet data collected from a variety of detector platforms and provide clear, agency-ready documentation suitable for ESA Section 7 consultation, NEPA review, and state-level permitting.


Whether you need a second opinion on existing acoustic data or full vetting support for an ongoing survey program, Volant delivers reliable results that hold up to regulatory scrutiny.

Tricolored bat (Perimyotis subflavus) - bat species survey - Volant EcoServices

Biodiversity surveys are essential for understanding the presence and distribution of plant and animal species within a given area. Our biosurveys document species richness, identify sensitive or protected species, and assess overall ecosystem health.


Using standardized methodologies, we conduct surveys for a wide range of taxa, including mammals, birds, amphibians, reptiles, and invertebrates. Our detailed reports provide valuable insights for regulatory compliance, conservation planning, habitat management, and research initiatives, helping to protect and preserve natural resources.

Healthy forests are vital for biodiversity, carbon sequestration, and ecosystem stability. Our forest inventory services provide comprehensive data on tree species composition, stand structure, and forest health.


We conduct field-based measurements to assess tree density, age distribution, and habitat value, providing critical information for forest management, conservation planning, and sustainable land-use decisions. Whether for private landowners, government agencies, or conservation organizations, our forest inventories support informed decision-making to balance ecological and economic objectives.
