Environmental biologists investigate how human activities impact natural ecosystems by monitoring environmental conditions, conducting field assessments, and analyzing biological data. They earn a median annual salary of $80,060 as of May 2024, with employment projected to grow 6% through 2032. Most positions require at least a bachelor's degree in biology or environmental science, with master's degrees preferred for advancement.
Environmental biologists serve as frontline investigators of how human activities affect natural ecosystems. While you'll find them studying everything from river health to wetland boundaries, their focus is distinctly biological: examining how pollutants, development projects, and environmental conditions impact living organisms and the communities they form. Unlike general ecologists who may study natural systems broadly, environmental biologists concentrate specifically on human-environment interactions and often work directly with regulatory agencies and development companies.
An environmental biologist investigates the impacts of actions, pollutants, and conditions on wild communities. They usually focus on ecosystems rather than a particular species. For example, they may study "indicator species" such as mayfly nymphs, caddisfly larvae, and other macroinvertebrates living at the bottom of rivers, lakes, and streams to assess overall ecosystem health. They may delineate wetland areas, assess water quality, or investigate the impacts of a proposed development project. Their work often intersects with wildlife biologists and other environmental specialists.
What Does an Environmental Biologist Do?
Environmental biologists are mainly responsible for monitoring environmental conditions and conducting environmental impact assessments for development projects. These tasks usually involve significant fieldwork, such as maintaining environmental monitoring systems and collecting water and soil samples. Environmental biologists plan these monitoring and data collection programs. They must then analyze the chemical and biological data from the samples they've collected using mathematical and statistical techniques. They may use GPS equipment to record spatial information during field activities, and geographic information systems (GIS) to create maps from the GPS data.
When pollutant impacts are suspected, environmental biologists may work alongside environmental toxicologists to assess the effects of chemicals on organisms. Environmental biologists may also determine the impacts of wastewater discharge, agricultural and urban runoff, and other conditions. Many monitor pollution levels to ensure compliance with state and federal laws. Others may conduct wetlands delineations, classify wetland types, and conduct habitat assessments. Some are responsible for consulting with government agencies, obtaining required permits for clients' development projects, or submitting official comments on proposed environmental regulations for their organizations. Nearly all environmental biologists need to write and submit technical reports detailing their findings. Their efforts help protect ecosystems from the adverse effects of human activities and support conservation by providing scientific data that informs protection decisions.
A Day in the Life of an Environmental Biologist
A typical day varies considerably based on season, project phase, and specialization. During active field seasons (typically spring through fall), an environmental biologist might start their morning by reviewing the day's sampling schedule and checking weather conditions that could affect fieldwork. Mid-morning often involves traveling to field sites, which may include wetlands, streams, or proposed development locations. The bulk of the day could include collecting water samples, documenting plant species for wetland delineations, or setting up monitoring equipment.
Afternoons might shift to laboratory work, where biologists analyze samples, enter data into databases, and begin preliminary interpretations of results. Much of the work requires attention to detail and precise documentation. During winter months or between field seasons, environmental biologists spend more time in the office preparing technical reports, developing sampling plans for upcoming projects, coordinating with regulatory agencies on permit applications, and analyzing accumulated field data using statistical software. Client meetings and site assessment presentations also fill the calendar, requiring clear communication of complex scientific findings to non-technical audiences.
Where Does an Environmental Biologist Work?
Environmental biologists most often work for state and federal government agencies. While the US Bureau of Labor Statistics (BLS) doesn't report on environmental biologists specifically, it reports that as of May 2024, most environmental scientists work across several sectors. Approximately 22% work in state government agencies, while another 21% work for companies providing management, scientific, and technical consulting services. These professionals usually help companies comply with regulations and conduct environmental impact assessments for their development projects. About 14% work for local government agencies, 10% provide architectural and engineering services, and 7% work for the federal government.
Environmental biologists work in offices and laboratories but also spend significant time in the field, where they are exposed to all types of weather. Workers may also be exposed to pollutants, chemicals, and possibly water-borne pathogens while collecting samples or working with them in the lab. Following established safety precautions is essential. Extensive travel to reach work sites may be required, and some field locations can be pretty remote. Many environmental biologists find this mix of indoor and outdoor work appealing. However,h it's essential to consider whether you prefer predominantly field-based or lab-based work when choosing your career path.
Most environmental scientists, including environmental biologists, work full-time. They may work long or irregular hours in the field, particularly during peak sampling seasons, and may need an in-state driver's license to operate government vehicles.
Essential Skills for Environmental Biologists
Success as an environmental biologist requires a blend of technical expertise and interpersonal capabilities. On the technical side, proficiency with GIS mapping and spatial analysis software is nearly essential, as is competence with statistical analysis programs such as R or SAS. Environmental biologists must be skilled in water quality testing procedures, plant and species identification, and standard laboratory techniques. GPS equipment operation and field sampling protocols are fundamental to the work. Many positions also require knowledge of wetland delineation methods and habitat assessment frameworks.
Soft skills prove equally important. Environmental biologists spend considerable time writing technical reports and permit applications, so strong scientific writing abilities are crucial. Understanding regulatory compliance requirements helps navigate the complex web of federal and state environmental laws. Because projects often involve explaining findings to developers, agency officials, or the public, the ability to communicate technical information to non-technical audiences matters greatly. Project management skills help coordinate multiple field assessments and meet deadline-driven permit processes. Finally, meticulous attention to detail in data collection and documentation ensures the scientific integrity that regulators and courts may scrutinize.
