Introduction In June 2014, AusPlots, part of the Terrestrial Ecosystems Research Network (TERN), undertook surveys on Mundrabilla Station, Western Australia. The surveys involved vegetation and soils work following the AusPlots Rangelands methodology, with 3 plots completed. The plots are part of over 580 plots completed nationally. Figure 1 shows the national AusPlots plot network, and Figure 2 shows the locations of the plots on Mundrabilla Station.

This report provides a snapshot of some of the data which was collected during the survey work. A more detailed description of the methods used can be found online in our AusPlots Rangelands Survey Protocols Manual (White et al. 2012), available from our website www.ausplots.org.

Accessing the Data All of the data the AusPlots collects is freely available online through the AEKOS data portal at www.aekos.org.au. It can also be viewed on the Soils to Satellites website which contains a range of useful visualisations sourced from the Atlas of Living Australia. At http://www.soils2satellites.org.au/.

Point intercept data The point intercept method is a straightforward method that is readily repeatable and requires little instruction to produce reliable plot information. It provides accurate benchmark data at each plot including substrate type and cover; as well as species structural information such as growth form, height, cover and abundance and population vertical structure. The demographic information produced at each plot can be compared spatially to indicate plot diﬀerences, and temporally to indicate change over time. Additionally, the cover data collected at each plot can be used to validate cover data extrapolated through remote sensing techniques.

Plant collections Each species that is found within the plot has a herbarium grade sample taken. These have all been formally identified by the WA herbarium. Much of the material is then lodged at the WA herbarium or at the Ausplots facility in Adelaide.

Leaf tissue samples All of the above samples also have leaf tissue samples taken. This involves placing leaf samples from each species into a cloth bag and drying them on silica desiccant. All of the dominant species have an extra 4 samples collected. These samples are available for use on application to Ausplots facility in Adelaide. They are able to be used for genetic analysis, Isotopic composition and range of other uses.

Site description information Contextual information is also collected at each site. This includes measures of slope an aspect, surface strew and lithology, and information on the grazing and fire history of the site. The sites location is also recorded with a differential GPS and the plot corners and centres (with landholder permission) marked with a star picket.

Structural summary Detailed structural summary information is also collected at each site. When combined with the height and cover information from the point intercept data it enables the creation of structural description compatible with and NVIS level 5 description.

Leaf Area Index In plots where a mid and/or upper canopy is present a measure of Leaf Area is recorded. The tool used is an LAI- 2200 and it captures LAI measurements in a range of canopies using one or two sensors attached to a single data logger (LI-COR 1990). The LAI data has a range of potential application such as studies of canopy growth, canopy productivity, woodland vigour, canopy fuel load, air pollution deposition, modelling insect defoliation, remote sensing, and the global carbon cycle.

Basal area Basal area measurements are collected across plots where woody biomass is taller than 2m. Basal area measurements provide information useful for calculating biomass and carbon levels and for structural studies. The wedge aperture, the length of string – 50 cm (and hence the distance from the eye and subsequent angle from the eye to the edges of the wedge aperture) and species count are all important in calculations. Algorithms developed for use with the basal wedge include the above data to calculate plant basal area on a per hectare basis even

3 though species are counted outside the one hectare plot area. The method is plotless but used because it is based on the concept of circles (trunks/basal area) within circles (circular plots) – the area of one varies proportionally to the change in the area of the other. Use of the basal wedge may be superseded by further improvement of the 3D photo point method and development of algorithms to provide information on vegetation community structure.

Soil classification Soils descriptions i.e. information recorded, number of recordings and coverage of locations, are generally poor across the rangelands region of Australia. The plot descriptions and soil characterisations collected will substantially alleviate this paucity of information. The data collected can also be used to increase the reliability of the rangelands component of the Soil and Landscape Grid of Australia, produced by the TERN facility consistent with the Global Soil Map specifications. Analyses of the collected samples will greatly enhance the level of knowledge (e.g. nutrient and carbon levels) and hence understanding of rangelands soils and how they will respond to climate change and management options. It is hoped to eventually be able to analyse all 9 of the soil pits from within the plot using a number of different methods e.g. wet chemistry, MIR or NIR (mid infrared spectrometry or near infrared spectroscopy) either individually to provide a measure of variation of the parameter being measured across a plot or bulked together and a sub-sample extracted and analysed to provide a mean value for that parameter across a plot.

Soil meta barcoding samples Metagenomics is the study of genetic material recovered directly from environmental samples. Soil metagenomics provides the opportunity to understand what organisms are present at survey plots and provides an indication on their abundance. The collection techniques result in a bias towards higher order organisms. All of the Ausplots withon Mundrabilla Station have soil meta barcoding samples collected.

Soil bulk density The soil bulk density (BD), also known as dry bulk density, is the weight of dry soil divided by the total soil volume. The total soil volume is the combined volume of solids and pores which may contain air or water, or both. The average values of air, water and solid in soil are easily measured and are a useful indication of a soils physical condition. Soil test results are most often presented either as a percentage of soil (e.g. % organic carbon) or as a weight per unit of soil (e.g. nitrogen, mg/kg). As bulk density is a measure of soil weight in a given volume, it provides a useful conversion from these units to an area basis unit (e.g. t/ha). The resulting number gives an easily understandable idea of the carbon storage or nutritional status of the soil on an area basis.

3D Photo Panorama AusPlots uses a three-dimensional method for photographing the site. This involves taking three 360-degree panoramas in a triangular pattern. This allows the creation of a 3D model of the vegetation within the site which can be used to monitor change over time, track plot condition as well as providing a unique, fast measurement of basal area and biomass. One of the Photo panorama for each of the plots is shown below.

Potential Uses for AusPlots Data from Mundrabilla Station The AusPlots survey method was developed out of a dire need for consistent, national scale ecological data and surveillance monitoring. As such, the data can be used in a range of ways both on Mundrabilla Station but also to allow comparisons across the continent. Currently, a range of researchers and land managers make use of the data and samples. Some example applications that may be applicable within the region are listed below.

 Assessing vegetation change using the AusPlots methodology as both a baseline and a continued surveillance monitoring tool.  Detecting the impact of invasive species based on soil and vegetation data.  Ground-truthing satellite derived vegetation and soil data  Soil carbon analysis using the soil bulk density samples  Mapping soil phosphorus, nitrogen and other nutrients using soil pit and subsite samples  Assessing fuel loading using the basal area and leaf area data.  Use of the leaf tissue samples for genetic and isotopic analysis.
