On Call Biologists often support a variety of projects, including wildlife surveys, habitat assessments, environmental impact studies, and compliance monitoring for construction or land development. You may work in diverse environments such as wetlands, forests, urban sites, or along waterways, sometimes during irregular hours or in response to urgent client needs. Collaboration with ecologists, environmental consultants, land managers, or government agencies is common, offering the opportunity to build a broad professional network. The variety of projects both challenges biologists to adapt quickly and provides rich, hands-on learning experiences in the field.
