Postpone Announcement

As you know, the ILTER OSM 2022 was planned for 12-16 September 2022. Currently there are still significant travel restrictions in place as a result of the Covid pandemic in China, and it is unlikely that these will be lifted very soon.


Therefore, and in light of our wish to enable broad face-to-face attendance at the meeting, we have decided to postpone the ILTER OSM for one year to 2023. We assume that this will enable all of us to hold a memorable event in Kunming in 2023, which will definitely be much more fruitful than a mostly virtual conference this year.


The ILTER OSM is an international academic conference and held every three years. It is the gathering of the global Long-Term-Ecosystem-Research community and interested representatives of other fields. The new date has not yet been fixed but will be communicated in due time. For latest information, please visit the events section on our website.



The International Long Term Ecological Research Network, ILTER, is a network of networks, encompassing hundreds of research sites located in a wide array of ecosystems that can help understand environmental change across the globe. ILTER's focus is on long-term, site-based research and monitoring. 

ILTER’s vision is a world in which science helps prevent and solve environmental and socio-ecological problems. ILTER contributes to solving international ecological and socio-economic problems through question and problem-driven research, with a unique ability to design collaborative, site-based projects, compare data from a global network of sites and detect global trends.

Specifically, the purpose of ILTER is to provide a globally distributed network and infrastructure of long-term research sites for use in the fields of ecosystem, biodiversity, critical zone and socio-ecological research, and to secure highest quality interoperable services in close interaction with related regional and global research infrastructures and networks.

 ILTER organizes an Open Science Meeting (OSM) every three years to foster scientific exchange and community building within and beyond the ILTER networks around the globe.
