Role Overview
This role is responsible for leading and coordinating ecology, biodiversity and statutory Biodiversity Net Gain (BNG) services across projects. You’ll act as the technical authority, ensuring delivery is compliant and aligned with planning, legal and client requirements.
Key Responsibilities
Ecology and Biodiversity Services
- Overall accountability for ecology and biodiversity data across projects, including statutory biodiversity metrics, habitat condition assessments and BNG performance throughout the project lifecycle.
- Technical assurance of all ecology outputs, including QA of PEAs, UKHab mapping, BNG metrics, EcIAs, HMMPs, Biodiversity Gain Plans and planning submissions.
- Setting service excellence standards to ensure outputs are consistent, defensible and aligned with industry guidance (CIEEM, DEFRA, Natural England).
- Developing delivery strategies and supporting fee proposals, including defining scope and challenging inefficiencies, cost risks or over-scoped work.
- Driving digital innovation, including GIS-enabled tools for ecological screening, BNG assessments and data integration.
- Integrating wider nature-based metrics (BNG, EBN, UGF and ecosystem services) to inform design, reporting and sustainability outcomes.
Team Leadership and Collaboration
- Managing and mentoring ecology team members, including technical development in statutory metric application, condition assessment and planning compliance.
- Working closely with landscape, sustainability and design teams to embed ecology early and influence layout, red line boundaries, landscape strategy and cost planning.
- Maintaining strong links across internal nature and sustainability teams to ensure consistency and sharing of best practice.
