Who are we?

Ecoleg LLP is a specialist ecological consultancy based in Cardiff, working across Wales and England. The practice is led by three partners with a core team of six, supported by a trusted network of experienced associate ecologists who work with us regularly.

We work with contractors, consultancies and public bodies on rail, infrastructure and land management projects, from ecological appraisals and protected species surveys to on-site supervision and licensing. Our specialist expertise spans bats, dormice, ornithology, botany and invertebrates. We can also survey where others can't: our team includes ecologists qualified in rope access, tree climbing and aerial rescue, and confined space entry.

We are chartered, licensed, PTS-qualified and SafeContractor accredited, so we can mobilise quickly and work safely wherever the job is: on the railway, at height or below ground.

Our mission: To help nature help you.
