The dataset comprises well-designed survey data from the first fuel load survey across 192 transects within the 48 AusPlots Forests, 1-ha monitoring plots across Australia. Data includes: [1] Site identifiers (ID and Site Name) and site- or transect- specific notes from the fuel survey campaign; [2] Transect survey dates; [3] Transect photograph numbers and attributes (Bearing, Slope and Aspect); [4] Fuel measurements (Grass and Litter height; Duff depth; Fine Woody fuel counts and Coarse Woody fuel counts and diameter; Projective cover for biomass components (Grass, Litter, Herbs, Vines and Shrubs), and Mass of biomass components (Grass, Litter, Herbs and Vines)); [5] Moisture content for biomass components (Grass, Litter, Herbs and Vines).
Descriptions of the data and coding protocols used in the database are explained in (a) the database itself; (b) the explanatory file attached to this dataset and (c) the Ausplots Forest Monitoring Network Manual. The protocols and coding used in this module are drawn directly from international forest fuel survey protocols and are consistent with other Australian forest fuel inventory methodologies.

Purpose
The TERN AusPlots Forest Monitoring Network aims to establish a continental scale plot based monitoring network that improves our understanding of tree growth, forest productivity and carbon dynamics in tall eucalypt forests in relation to continental scale environmental gradients. This permanent plot network provides the infrastructure and data for tracking all aspects of forest dynamics over long periods of time. Between October 2014 and March 2015, fuel load surveys were conducted in the 48 large 1-ha Ausplots Forest Monitoring Network plots in mature, highly productive tall eucalypt forests across the Australian continent.
TERN AusPlots is a plot-based surveillance monitoring program, undertaking baseline assessments of ecosystems across the country. The aim of AusPlots is to establish and maintain a national network of plots that enables consistent ecological assessment and ongoing monitoring. The AusPlots network collects a range of field data for integration with other existing data sources and current knowledge.
Lineage
2) Woody fuel counts : Woody fuels were measured in four size classes [(1) 0-6 mm; (2) 6-25 mm; (3) 25-76 mm; and (4) >76 mm] at varying scales along the 28.3 m transect. Woody fuels were measured as counts of vertical planar intercepts. Size classes (1) and (2) were counted along two 2 m sub-transects between 6-8 m and 20-22 m. Size class (3) is counted in two 4m sub-transects between 5-9 m and 19-23 m. Size class (4) is counted along the entire 28.3 m transect. The diameter at intercept is also recorded for size class (4), as well as the estimated diameter of the hollow centre (if present) [see Manual].
3)Fine litter, grass, herbs and vines measurement: The projective cover and mass of fine litter, grass, herbs and vines were recorded separately from two 1x1 m quadrats at 7-8 m and 22-21 m along the transect. A representative sample of each component from the site was collected, taken to the lab, weighed, dried to a constant weight at 70°C and re-weighed to estimate moisture content [see Manual].
4) Duff depth measurement : The depth of duff (where present) was recorded from two soil cores per 1 x 1 m quadrat, totalling 16 across the site [see Manual].
5) Soil Sampling: Soil samples were collected from 1 x 1 m quadrats, with four 10 cm soil cores being collected from each transect (two from each quadrat). Soil cores were bulked for each transect, kept in a cooler bag during the day, and dried in an oven for 48 hours at 105 degrees celsius on return to the lab.
6) Installation of litterfall traps: The litterfall traps used for the TERN AusPlots Forest Monitoring Network sites are 0.75 x 0.75 m in dimension and have an input area of 0.56 m2. Four litterfall traps were placed across the site. One corner of the litterfall trap aligned with a steel dropper. The frame for each litterfall trap has constructed from 32mm diameter PVC pipe, including four 57 cm lengths and four 6.8 cm lengths (which form the sides), and four 47 cm lengths (which form the legs). These are joined with four right-angle elbow joins and four T- joins. The net for the litterfall trap was manufactured from a 1.8 x 1.8 m piece of shadecloth, which has splits along each side through which the side lengths of PVC pipe were threaded. The frame was assembled and secured with PVC cement solvent on- site. The legs have pre-drilled holes at the base, and have been pinned to the ground using tent pegs.
7) Installation of temperature and humidity data loggers : Three iButton data loggers have been installed at each site. Two are Thermochron DS1922L, which record temperature at four-hourly intervals, and one is a Hygrochron DS1923, which records both temperature and humidity at four-hourly intervals. iButtons have been attached to plastic fobs, which were wired on to the top of a steel dropper and placed inside the yellow safety cap.
