The Robson Creek site lies on the Atherton Tablelands in the wet tropical rainforests of Australia (17.121 S, 145.634 E) at 680-740 m elevation. It is situated in Danbulla National Park within the Wet Tropics World Heritage Area. The climate is seasonal with approximately 60% of rain falling between January – March and the landform is moderately inclined with a low relief although the Lamb Range rises sharply to 1276 m asl immediately to the north of the plot.
The Wet Tropics Bioregion of Australia is situated on the north-eastern coast of Queensland, between Cooktown to the north and Townsville to the south. Approximately 40% (7200 km2) of the region is covered by rainforest. Features of the region include very high plant and animal endemism, characteristics of both Gondwanan and Indo-Malaysian forests, and frequent cyclonic disturbance. To the north, south and west of the bioregion the climate becomes drier and the vegetation quickly grades to woodland.
The Robson Creek 25 ha plot was established in 2009. All stems ≥ 10 cm diameter are measured, tagged and mapped. Data can be accessed via the Supersites Data portal. In 2013, a 40 m flux tower was established adjacent to the plot. Infrastructure at the plot is limited to a simple field shed, however world class research facilities are located at CSIRO Atherton, a 35 minute drive from Robson Creek. Accommodation can be found at state government campsites http://www.nprsr.qld.gov.au/parks/danbulla/about.html (10 minutes), Tinaroo (20 mins) or Atherton (35 mins).
The Robson Creek 25 ha vegetation survey plot has been included in the Smithsonian Tropical Research Institute’s Center for Tropical Forest Science - Forest Global Earth Observatory (CTFS-ForestGEO) global network of forest research plots. This network dedicated to the study of tropical and temperate forest function and diversity.

Far North Queensland Rainforest - Robson Creek Ancillary Datasets
In January 2014 Matt Bradford (CSIRO) was interviewed by the ABC Radio National Off Track program at the Robson Creek flux tower.
Education and Outreach
A ClimateWatch trail near Robson Creek has been developed in collaboration with the Tinaroo Environmental Education Centre, a Queensland state government-run centre in Far North Queensland with a 25 year history of providing education on land care, outdoor pursuits and sustainability. The Tinaroo Environmental Education Centre ClimateWatch trail enables casual citizen scientists to contribute to phenological and biodiversity datasets that will complement monitoring at Robson Creek.
