This section of the website is for the ECN community (site managers, CCU staff, etc.). Here you will find essential information and links to a range of tools supporting site managers and others. Please scroll down to find information on: key sampling dates; providing data from your site; contacting people in ECN; related LTER inititiatives (ILTER, eLTER, etc.); checking/changing your site description on DEIMS-SDR; ECN performance indicators; providing details of relevant publications and requests for ECN data.

Providing your data

The Site Managers' secure pages on the ECN Data Centre contain links to the Data Progress Charts, Data Transfer Documents and ECN Coding Lists. Also available are resources to aid vegetation data entry and a facility to check the information held about your site in the database (and on the web site).

Contacting the CCU and other Site Managers

We operate a simple mailing list to send group-wide messages to ECN site managers and the CCU team. For details please contact Andy Sier (CCU).


Related LTER initiatives: eLTER, ILTER, DEIMS-SDR, etc.

Site-based Long-Term Ecosystem Research and monitoring (LTER) takes place around the world by networks similar to ECN. A global network - ILTER - provides a forum for these networks to exchanges information and work together. In Europe, eLTER brings together the LTER networks of many European nations. ILTER manages DEIMS-SDR, an online register of LTER sites and datasets.


DEIMS-SDR provides descriptions of LTER sites around the world, including those in the UK. The repository's coordinators periodically request sites and networks to check and update their site records, but even in the absence of such requests, it is good practice to check these descriptions - and the descriptions of the sites on our own ECN website - annually.

Andy Sier (ECN CCU) is ECN's main contact point with respect to the ECN data in DEIMS-SDR. However, since Site Managers know their site better than anyone, and since checking and updating the data for each site is now much easier, it would help if site managers/contacts could check the data for their site and in particular, add data to empty fields. Please refer to the instructions below.

  • To find your site record simply use the search box. This may return more than one entry, including site records and datasets. Icons indicate the type of record. Be sure to select the site description record. You can also filter the search using the checkboxes
  • Please read through your site record and note anything that is incorrect or that could be added
  • To edit your record, click on 'Log in' and use the UK ECN login details (please contact Andy Sier for assistance)
  • Tutorials provide more information about DEIMS-SDR and how to edit records. If need further help, please contact Andy Sier
  • IMPORTANT: If you edit the site descriptive text, please also check how your site is described on ECN's websites (this one and the Data Centre). It is likely that those descriptions will also need updating.

Performance indicators

Publications and data requests

We maintain a catalogue of ECN-related publications such as scientific papers describing research using ECN data and/or sites. We also try to keep a record of any requests made for ECN data. Providing this information helps us to monitor interest in, and use of, ECN data and sites.
