Welcome to ILTER

International Long Term Ecological Research (ILTER) is a 'network of networks', a global network of research sites located in a wide array of ecosystems worldwide that can help understand environmental change across the globe. ILTER's focus is on long-term, site-based research.

ILTER can contribute 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.

Most ILTER members are national or regional networks of scientists engaged in long-term, site-based ecological and socioeconomic research (known as LTER or LTSER). They have expertise in the collection, management and analysis of long-term environmental data. Together they are responsible for creating and maintaining a large number of unique long-term datasets.
