Who we are

We are the leading professional membership body representing and supporting ecologists and environmental managers in the UK, Ireland and abroad. Our Vision is of a healthy natural environment for the benefit of current and future generations.

With a growing membership and an increasingly influential voice we are transforming the professionalism of the sector, just as our members are transforming understanding of, and attitudes towards, protecting and enhancing our natural environment.

By working together, we believe we can make a difference, leading to a world rich in biodiversity for the benefit of us all, now and in the future.

Our history

We were formed in 1991 as the Institute of Ecology and Environmental Management. From small beginnings, we have grown into an increasingly influential professional body – setting standards, sharing knowledge and providing sound advice to governments on all aspects of ecological and natural environmental management practice.

Our leadership was recognised in 2013 when we were awarded our Royal Charter, becoming the Chartered Institute of Ecology and Environmental Management (CIEEM – pronounced “sy-eem”). That same year we launched our first ever Competency Framework for the profession, which has become the benchmark for practice standards and membership progression.

We were further recognised for our contribution to the public good in June 2020 when we became a registered charity in England and Wales.
