We present repeated stem measurement data from 20, 0.5 ha (100 m x 50 m) permanent rainforest plots in northern Queensland, Australia from 1971 to 2013. The plots have a rainfall range of 1200 to 350... more0 mm, represent eleven vegetation types, six parent materials, and range from 15 m to 1200 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. Data is presented for 10998 individual stems with plot stem densities at establishment ranging from 476 to 1104 stems ha-1. Due to the wide geographical range of the plots, no species dominate, although the families Lauraceae, Rutaceae and Myrtaceae contribute a large number of species. Basal area values at establishment ranged from 28.6 to 63.3 m2 ha-1 and showed no trend of increasing or decreasing over time due mainly to regular disturbance and recovery from natural events such as cyclones. In addition to stems ≥10 cm DBH data, we present height data, floristic data from understory stems (≥50 cm height to <10 cm DBH), an auxiliary species list (including vines, epiphytes, ferns, grasses, herbs and other life forms), and a list of voucher specimens lodged in herbaria. The data collected from the 20 plots provides an insight into the floristics, structure and long term forest dynamics of Australian tropical rainforests and allows direct comparisons to be made with long-term monitoring plots at a global scale.less
1173.2 TERN (ANU): Permanent Plots - CSIRO Rainforest Permanent Plots of North Queensland - Published 19 Jun 2017
The data represents the output from a Northern Australian Environmental Resources Hub NESP project titled "Mapping to underpin recovery planning for Littoral Rainforest and Coastal Vine Thickets (LRF)... more in the Wet Tropics".
The following spatial layers were derived:
• LRF vegetation that ‘wholly-equates’ to the EPBC Listing Advice
• ‘Potential’ LRF delineating areas consistent with broad characteristics of the community described in the EPBC Listing Advice
• Inundation statistics for each patch of wholly-equate LRF and potential LRF (patches defined by RE mapping) indicating:
o the proportion of each patch inundated with 80 cm sea-level rise
o the proportion of each patch inundated at each of 8 ARIs with and without sea-level rise
o the ARI at which a patch first becomes inundated
o the ARI at which a patch is >20% inundated
o the ARI at which a patch is >50% inundated
The data available for download include two GIS shapefiles and one excel spreadsheet:
1.Shapefile LRF_Wholly - includes the patches that wholly equate with the EPBC listing advice and inundation statistics for those patches
2. Shapefile LRF_Potential_rf - includes the patches that are captured as consistent with the broad characteristics of the EPBC listing advice and inundation statistics for those patches
3. Excel spreadhseet 'Shape file heading descriptions' provides a detailed description of the attributes contained in the shapefiles.

NESP Northern Hub Littoral Rainforest an - Spatial data - Published 24 Feb 2017
This database presents an index of the intensity, frequency and density of cyclone occurrence in the Australian region. It has been derived from data held in CSIRO CAMRIS database and originally coll... moreected by the Bureau of Meteorology from 1958 - 1990. The cyclone_density code in the coverage represents: 1 Australia, 2-23 the nominal index of cyclone density/intensity, as per the Bureau of Meteorology cyclones database.
Absolute External Positional Accuracy Check: +/- one degree.
Non Quantitative accuracy: The attribute called nominal_index holds values 0-23, which represent the intensity and density of cyclone occurrence. The attribute called cyclone_density provides a subjective definition of the density of cyclone occurrence:
Nominal_Index : Cyclone_Density
0 : No cyclone occurrence.
1 : Australian Continent.
2 : Low.
3-8 : Medium
9-16 : High.
17-23 : Very high.
Conceptual consistency: Coverages are topologically consistent. No particular tests conducted by ERIN.
Completeness omission: Complete for the Australian continent and oceans.less
