Ecologist, Ashwell, Hertfordshire

We’re looking for an Ecologist to join our friendly and highly skilled team in Ashwell, Hertfordshire.

CSA Environmental is an independent, multidisciplinary consultancy of 85 people across five offices.

Our Ashwell team of 14 ecologists form part of a wider team of 50+ ecologists across the business that have built a strong reputation for providing clear, reliable ecological advice, and for encouraging clients to go beyond standard expectations.

We are proud to hold the Great Place to Work certification (2026), independently awarded based on our team’s own feedback.

It reflects what we’ve always believed: that good work comes from people who feel valued, trusted and supported to grow.

Ecology is not about compliance, it’s increasingly the discipline that shapes how development land is planned, designed and valued.

At CSA, we take that seriously.

We actively encourage clients to look beyond mandatory requirements and to think about what genuine long-term biodiversity improvement looks like on their sites.

That ambition runs through our project work, our habitat bank schemes, and the advice we give at every project stage.

• What you’ll be doing
• Undertaking UKHab baseline field surveys, with and without support/input from other ecologists in the team
• Undertaking desktop data searches for biological records/information and discussions with nature conservation consultees, as required
• Obtaining and reviewing local plans, planning policies and other relevant policy information, and developing a basic working knowledge of the planning system
• Preparing Preliminary Ecological Appraisal reports using our standard framework and applying standard CIEEM evaluation criteria, for final review by a Senior/Associate Ecologist
• Undertaking protected species surveys, dependent on personal experience, and providing support on surveys with our other ecologists
• Hold at least one personal survey licence, and demonstrating progress towards obtaining further licences
• Preparing reports following protected species surveys for review/completion by a Senior/Associate Ecologist
• Interacting and communicating with clients and other contacts in a professional and responsible manner at all times, across telephone, written and electronic communications
• Working professionally with all colleagues and supporting the Senior/Associate Ecologists as required, including a reasonable contribution to general administration work
• Assisting with the training and professional development of junior colleagues
• Assisting with the preparation and implementation of EPS and other licence applications
• Becoming familiar with and using QGIS and other graphics packages used by CSA, to produce simple maps and plans suitable for external use (e. g. site location plans, habitat plans)
• Demonstrating and developing an understanding of Biodiversity Net Gain, including associated legislation and best-practice guidance, along with a working knowledge of the Statutory BNG metric and developing QGIS skills to measure habitat areas and populate the metric
• Undertaking additional work outside of normal working hours, as reasonably required by specific survey needs and company workloads, on a par with the other ecologists (regular dusk and occasional dawn bat surveys, overnight newt surveys, etc.).
• At peak times this may involve 2–3 nights in a week (not including weekends)
• Playing an active role in organising work and survey planning, to benefit the smooth running of the team
• Complying with all CSA Health and Safety procedures in the course of your work, including consideration for the safety of others where leading a survey or site visit
