Observations of changes in phenology have provided some of the strongest signals of the effects of climate change on terrestrial ecosystems. The International Tundra Experiment (ITEX), initiated in the early 1990s, established a common protocol to measure plant phenology in tundra study areas across the globe. Today, this valuable collection of phenology measurements depicts the responses of plants at the colder extremes of our planet to experimental and ambient changes in temperature over the past decades. The database contains 150 434 phenology observations of 278 plant species taken at 28 study areas for periods of 1–26 years. Here we describe the full data set to increase the visibility and use of these data in global analyses and to invite phenology data contributions from underrepresented tundra locations. Portions of this tundra phenology database have been used in three recent syntheses, some data sets are expanded, others are from entirely new study areas, and the entirety of these data are now available at the Polar Data Catalogue (

Funding: Pat Webber and Terry Callaghan were the initial leaders of ITEX building on their involvement in the IBP Polar Biome program, and we thank them for their vision for this network. We thank A. Maria Fosaa for establishing the ITEX site in the Faroe Islands. We thank M. Dalle Fratte, D. Cooley, O. Durey, C. Eckert, J. F. Johnstone, C. Kennedy, V. Lamarre, G. Levasseur, C. Spiech, J. Svoboda, and R. Wising; the Herschel Island Qikiqtaruk Territorial Park staff, including E. McLeod, S. McLeod, R. Joe, P. Lennie, D. Arey, S. Goosen, D. Gordon, L. Meyook, J. McLeod, P. Foisy, C. Gordon, J. Hansen, A. Rufus, and R. Gordon; Quttinirpaaq National Park staff; the Greenland Ecosystem Monitoring program; the Warming and species Removal in Mountains (WaRM) coordinators, N. Sanders, A. Classen, and M. Sundqvist; as well as the many other individuals who established experiments and collected detailed phenology observations. We thank local communities for welcoming our research teams on their land, the Qamani’tuaq, Mittimatalik, Aujuittuq, Iñupiat, Waveroo, Cheyenne, Resolute Bay, and Finse Alpine Research Center, among many others.
