Chartered Ecologist (CEcol)

CIEEM’s Register of Chartered Ecologists, under powers conferred by the granting of a Royal Charter on 1st April 2013, recognises the effective application of knowledge and understanding of the science of ecology by professionals.

Chartered Ecologists are active professionals who use their knowledge, experience and influence to promote and advance ecology as an applied discipline. They may work or have worked in local or national government, consultancy, the voluntary sector, statutory agencies, industry or academia but they are united by three common characteristics:

  1. their advice and practice is based on a fundamental understanding of ecology and the critical evaluation of scientific evidence;
  2. they work in accordance with high standards of professional conduct; and
  3. they can communicate complex ecological concepts and ideas confidently and effectively to a wide range of audiences.

As our natural environment faces ever-increasing pressures and threats there are signs that society is starting to recognise and value the vital life support, provisioning, regulating and cultural services it provides. Chartered Ecologists are at the forefront of work to protect and enhance the natural environment and to safeguard, manage and restore these services for the benefit of nature and society.

Before joining the Register, applicants are rigorously assessed to ensure that they are fully competent and confident practitioners. Registrants are periodically re-assessed to ensure that they have maintained the high level of competence required. Chartered Ecologists are identified by the post-nominal letters ‘CEcol’.

Admission to the Register of Chartered Ecologists is currently open to:

  • Fellows or Full members of CIEEM; and
  • Members of other professional bodies, licensed by CIEEM, such that their members can apply to CIEEM to join the Register. Details of licensed professional bodies will be listed below as and when a license is granted.


All applicants are required to meet defined eligibility criteria in order to be assessed for registration. These are:

  • Evidence of being an ‘active’ ecologist whether in an employed, self-employed, retired or otherwise voluntary capacity. This may include contributing expertise, being a source of expert advice and guidance and sharing knowledge.
  • Evidence of compliance with the mandatory minimum Continuing Professional Development (CPD) requirement. Registrants may be asked to supply evidence, through a random auditing process, of continuing to meet this requirement whilst on the Register.
  • Evidence of continuing compliance with CIEEM’s Code of Professional Conduct with no complaints upheld in the three year period leading up to the application.
  • Evidence of meeting the minimum competence requirements at the Accomplished or Authoritative levels as defined by CIEEM’s Competency Framework. We strongly recommend that, in the first instance, you complete a self-assessment of your competence level for each of the competencies within CIEEM’s Competency Framework to satisfy yourself that you are working at the required level.

If you meet the eligibility criteria and are interested in applying for Chartered Ecologist status please register your interest using the form at the bottom of this page.

Supporting your CEcol application

Your Chartered Ecologist application will be assessed against the Accomplished and/or Authoritative levels of our Competency Framework. The Framework specifies the levels of competence expected of our members at different professional grades and provides a competence-based assessment of membership and Chartered Ecologist eligibility.

There are five stages in the application process for Chartered Ecologist status:

  1. Check you are eligible to apply.
  2. Using the Competency Framework, carry out a self-assessment to satisfy yourself that you can evidence the minimum standard of competence required.
  3. Identify and approach two sponsors who will be able to endorse your written evidence and support you in identifying the best examples to demonstrate your competence.
  4. Prepare and submit the written part of your application (Stage 1).
  5. If successful at Stage 1, prepare for and attend your Professional Review Interview (carried out by video conference).
