Ecological Sciences

Finding balance…

Between business objectives and environmental impact

Our ecological sciences practice solves the wide range of ecological issues you may confront during your project. With extensive experience working with regulatory agencies, our multi-disciplinary team includes terrestrial and aquatic ecologists, wetland scientists, threatened and endangered species experts, and agency-approved surveyors of federally and state-listed plants and animals. We determine the presence or absence of protected species, offer measures to provide mitigation solutions, work with regulators to resolve conflicts, and recommend a permitting strategy. We’re experienced with natural channel stream design, watershed-based restoration, and on-site mitigation projects.
