Networks and sites

TeaComposition involves a large number of international research projects and networks.

They study ecosystem processes and functioning and responses to changes in environmental conditions.

They work with observational or experimental approaches.

Below is a description of these networks.


ILTER (International Long Term Ecological Research) consists of networks of scientists engaged in long-term, site-based ecological and socioecological research. Our mission is to improve understanding of global ecosystems and inform solutions to current and future environmental problems.

ILTER’s ten-year goals are to foster and promote collaboration and coordination among ecological researchers and research networks at local, regional and global scales and to improve comparability of long-term ecological data from sites around the world, and facilitate exchange and preservation of this data. Further, ILTER aims to deliver scientific information to scientists, policymakers, and the public and develop best ecosystem management practices to meet the needs of decision-makers at multiple levels and to facilitate education of the next generation of long-term scientists.

Number of sites:365

GLORIA (Global Observation Research Initiative in Alpine Environments) is a research network aimed to establish and maintain a world-wide long-term observation network in alpine environments. Vegetation and temperature data collected at the GLORIA sites will be used for discerning trends in species diversity and temperature. The data will be used to assess and predict losses in biodiversity and other threats to these fragile alpine ecosystems which are under accelerating climate change pressures.

Number of sites: 27 sites (with each 3 summits)

TreeDivNet (Tree Diversity Experiments Worldwide) is a global network of tree diversity experiments, which provides a unique platform for research on the relation between tree species diversity and ecosystem functioning in major forest types around the world.

Number of sites:16

ClimMani (Climate Change Manipulation Experiments in Terrestrial Ecosystems: Networking and Outreach) is a COST action focusing on Climate Change experiments. The aim of the Action is to improve the quality and appropriateness of experiments, data and modeling in climate change research and facilitate better use of experimental data for scenario building and process understanding. The COST action will bring together researchers designing, conducting and modelling climate change experiments and researchers analyzing and synthesizing results on the experimental impacts. ClimMani has a strong focus on developing common metrics in global climate change experimentation and has provided a strong platform for the discussions and fine tuning of the TeaComposition methodology.

INTERACT (International Network for Terrestrial Research and Monitoring in the Arctic) is an infrastructure project under the auspices of SCANNET, a circumarctic network of currently 79 terrestrial field bases in northern Europe, Russia, US, Canada, Greenland, Iceland, the Faroe Islands and Scotland as well as stations in northern alpine areas. INTERACT specifically seeks to build capacity for research and monitoring in the European Arctic and beyond, and is offering access to numerous research stations through a Transnational Access program.

Number of sites:10

TERENO (Terrestrial Environmental Observatories) is an interdisciplinary project that aims to investigate long-term ecological, social and economic impact of global change at regional level. For further information visit the website:

DIRT (Detrital Input and Removal Treatments) network is aiming to study the effects of changing litter inputs on soil organic matter dynamics. For more information visit the website:

Number of sites:3 +2 that will be established within the INTERACT TA

TeaComposition H2O

TeaComposition H2O is a separate but closely associated network led by the Blue Carbon Lab’s Drs Peter Macreadie and Stacey Trevathan-Tackett from Deakin University in Australia ( The Blue Carbon Lab specializes in carbon cycling in aquatic ecosystems from the microbes and gas flux to ecosystem restoration and carbon offset feasibility assessments.

Number of sites: NN
