LTER-Europe adheres to the policies of the International Long-Term Ecological Research Network (ILTER). Therefore, you will need to apply for membership of ILTER. The European LTER community has elaborated a simple description and guideline how national networks are typically initiated and set up.

Contact the LTER network in your country if one exists. You can find details of existing National Networks which are members of LTER-Europe, collaborate in European eLTER projects and are involved in the eLTER ESFRI process. The National Networks will review your site application and, if the criteria are met, they will be able to officially acknowledge (validate) your site from the national perspective in the site registry DEIMS-SDR.  Note that only inserting your site into DEIMS-SDR does not necessarily mean your site will become a part of your country’s national LTER network, which may have its own criteria for inclusion.
