In 1997, the 12 original members of GT-net established
the GTN ecology network at a meeting of experts on ecological
Envisioned as an umbrella network linking like-minded ecological
efforts, the group collaborates with GTOS on projects ranging
from the Net Primary Productivity demonstration project
and the future biodiversity TEMS module. Each member represents
a different focus within the ecology observation realm,
thus enforcing an overall effort for comprehensive, harmonized
data on ecological change.
Centre for the Studies of Arid Zones and Dry Lands (ACSAD)
ACSAD is a regional center for research and studies pertaining
to the development of the arid and semi-arid areas of
the Arab World. It was established in Damascus, Syria,
in 1971 within the framework of the League of Arab States.
Monitoring and Assessment Programme (AMAP);
AMAP researches the status of threats to the Arctic environment
and provides scientific advice to Arctic governments.
Ecosystem Research Network (CERN);
The CERN network contains 29 field stations in China that
observes a range of ecological fields including agriculture,
forests, grasslands, freshwater and marine ecosystems.
Group on International Agricultural Research (CGIAR);
CGIAR's projects focus on scientific advancement as a
means to increase agricultural productivity in over 100
countries, thus decreasing hunger, poverty and nutrition
Worldwide CO2 Flux Measurements (FLUXNET);
A global network of 150 micrometeorological tower sites
that use eddy covariance methods to measure the exchanges
of carbon dioxide (CO2), water vapor, and energy between
terrestrial ecosystem and atmosphere.
Cooperative Programme on Integrated Monitoring of Air
Pollution Effects on Ecosystem (ICP IM);
This network focuses on determining and predicting the
impact of air pollutants, particularly nitrogen and sulphur,
on terrestrial and freshwater ecosystems.
Long-Term Ecological Research (ILTER)
This network is focused on coordinating and linking the
efforts of long-term ecological observation systems worldwide.
d'Observatoires de Surveillance Ecologique à Long
ROSELT provides multi-disciplinary (soil, vegetation,
water resources, biodiversity, climate, and socio-economic)
data collected in a wide range of ecosystems, land uses,
and geographical coverage. It has a particular focus on
Environmental Change Network (ECN);
Also a worldwide ecological observation system, ECN has
developed climate change and water quality indicators.
Long-term Ecological Research Networks (LTER);
This observation system represents the United States component
of the larger ILTER project.
Network of Biosphere Reserves (MAB-BR)
Biosphere reserves are areas of terrestrial and coastal
ecosystems promoting solutions to reconcile the conservation
of biodiversity with its sustainable use.
