What is ITEX?

The International Tundra Experiment (ITEX) is a network of researchers examining the impacts of warming on tundra ecosystems. Currently, research teams at sites throughout the world carry out similar, multi-year coordinated experiments that allow them to examine vegetation change across the tundra biome.  The power of ITEX is the ability to perform quantitative synthesis of observations across many sites because the network of researchers agreed upon common protocols (outlined in the ITEX Manual).  See Syntheses & Data for examples and a list of ongoing projects.  Due to the long-term nature of the ITEX network, many of the sites also serve as a platform for monitoring and cross-site comparisons.
