The objective of the Australian Tundra Experiment(ATEX) is to assess the likely response of vegetation and invertebrates to temperature increases attained through passive warming. The Australian Tundra Experiment (ATEX) follows the International Tundra Experiment (ITEX) protocol (Molau & Mølgaard 1996, Jarrad et al. 2009) which focuses on the growth and phenological responses of cold adapted vascular plant species to environmental change, specifically, to an increase in summer (growing season) temperatures. In addition to monitoring vegetation responses, the experimental warming chambers were used to monitor the response of invertebrates to warming. Warming is achieved using hexagonal fibreglass open-top warming chambers (OTCs). The OTCs were set up in December 2003 at 4 sites within a 2 × 4.5 km area of the Bogong High Plains, Victoria, Australia, known as Rocky Knobs (36.90ºS, 147.27ºE). Two of the sites were established on vegetation that had been recently burnt by the 2003 bushfires. The sites are at approximately 1700 m above sea level and generally have snow cover of variable depth for 3 to 4 months each year (June-July to September-October). At each site, permanent plots of 1 m2 were selected to include as many of the common vascular grassland species as possible. Treatments were then allocated at random for a total of 40 control and 40 warmed plots. This dataset contains microclimate data for a subset of plots from 30-05-2014 to 2-05-2015.

This dataset presents the demographic monitoring (growth and survival) of 81 tree species based on repeated stem measurement data from 20, 0.5 ha (100 m x 50 m) permanent moist forest plots in northern Queensland, Australia from 1971 to 2019, as well as four additional plots of 0.1 to 1 ha whose monitoring began in the 2000s. The plots have a rainfall range of 1200 to over 6000 mm, represent eleven vegetation types, six parent materials, and range from 15 m to 1500 m above sea level. Except for minor disturbances associated with selective logging on two plots, the plots were established in old growth forest and all plots have thereafter been protected. Plots were regularly censused and at each census the diameter at breast height (DBH) of all stems ≥10 cm DBH were recorded. We only report the data for the 81 species studied in Bauman et al. 2022 (Nature), here. We also provide the climatology of these plots as well as the temperature, vapour pressure deficit, and maximum climatological water deficit of all intervals separating consecutive censuses, as used in the analyses of Bauman et al. 2022.
