Arctic ecosystems are changing in response to arctic warming, which is proceeding more than twice as fast as the global average. The International Tundra Experiment (ITEX) was established in the early 1990s to understand the effects of warming and environmental variability on tundra vegetation properties and ecosystem function. The ITEX program has been extremely valuable for detection of changes in tundra plant and ecosystem responses to experimental warming and to background climate change across sites that span the major ecosystems of the Arctic These files contain data representing the plant community composition and structure of ARCSS grid plots at Barrow and Atqasuk in a text tab delimited format. The data were collected on a subset of 30 plots at Barrow and 30 plots at Atqasuk.
