<p>The record comprises available data on the abundance of <em>Cassia</em> (<em>Senna artemesioides</em>) in an area of 7150 m² in the TGB Osborn (Koonamore) Vegetation Reserve (or Koonamore Vegetation Reserve (KVR)) since the early 1940s. Available data cover 26 instances from 1940 to 2014 and include the number of individuals of each species encountered, and their life stage (adult or juvenile).</p> <p><br /> This is version 2.0 of the Koonamore Cassia Corner data release and supersedes any previous versions.</p>

<p>Four paired transects were set up early in the Reserve history to monitor the spread of saltbush (<em>Atriplex</em> spp.) into the reserve across the eastern and southern boundaries. These were read regularly for the first few years but data from them are not available digitally. The transects were reactivated in 1989 and measurements are provided for four occasions: 1989, 2003, 2008 and 2014. Species are identified as <em>Atriplex vesicaria</em>, <em>A. stipitata</em>, or if uncertain as A. sp., using the classifications of the 'Census of South Australian Plants, Algae and Fungi' (2024*).</p> <p>This is version 2.0 of the Koonamore Saltbush Transect Survey data release.</p>

The dataset comprises vegetation cover and shrub occurrence along a point intercept survey in two 1 ha plots at the Great Western Woodlands site between 2013 - 2015

<p>The dataset contains raw records on the frequency and % cover of Australian plant species stored in TERN's AEKOS as at 23 February 2017. There is information on basal area data in addition.The data includes plant records for the following datasets: [1] Australian Ground Cover Reference Sites Database, [2] Biological Survey of South Australia - Vegetation Survey - Biological Database of South Australia, [3] Atlas of NSW database: VIS flora survey module, [4] Queensland CORVEG Database, [5] TERN AusPlots Rangelands, [6] Transects for Environmental Monitoring and Decision Making (TREND) (2013-present) and the [7] TREND-Biome of Australia Soil Environments (BASE). </p> Soil samples for physical structure and chemical analysis (14 sites) throughout Australia were also incorporated in addition (starting 2013). The sites were: [1] AusCover Supersites SLATS Star Transects, [2] Biological Survey of the Ravensthorpe Range (Western Australia), [3] Biological Survey of South Australia - Roadside Vegetation Survey, [4] Biological Database of South Australia, [5] South-Western Australian Transitional Transect (SWATT), [6] Koonamore Vegetation Monitoring Project (1925-present), [7] Desert Ecology Research Group Plots (1990-2011) and Long Term Ecological Research Network (2012-2015), Simpson Desert, [8] Western Queensland, Australia (plants only) and [9] the TERN AusPlots Forest Monitoring Network - Large Tree Survey - 2012-2015. In total, 97,035 sites were extracted and downloaded for individual and population levels. The download package contains site location files, separate data files for individual and population levels, citation details for individual surveys and notes on how to interpret the download.

<p>There are data from 30 quadrats in the TGB Osborn Vegetation Reserve, varying in size and duration of measurements, several of which are shown in the Reserve map. They range in size from large quadrats (100 x100 m), one 60 x80m, to intermediate (10 x10 m) and small (1x1m and irregular). Most quadrats are inside the reserve but some lie adjacent outside the fenced area.</p> <p>The data from the quadrats is presented in three different files:<br />(a) the abundance (numbers) of individuals of species within the quadrat, <br />(b) a selection of species measured within the quadrat (subplot), and <br />(c) individual plant locations within the quadrats.<br />This is version 2.0 of the Koonamore Vegetation Quadrats Survey data release.</p>

In the mid-1920's Professor Theodore George Bentley (TGB) Osborn, Professor of Botany in the University of Adelaide, put forward strong scientific arguments concerning the lack of knowledge of the ecology of arid zone vegetation, and the effect of grazing on it (Osborn, 1925). In 1925 negotiations proceeded between the University of Adelaide and Messrs Hamilton Wilcox Ltd to secure a parcel of land for the purposes of research on Koonamore Station, a sheep-grazing property approximately 400 km north-east of Adelaide. A parcel of land of around 390ha was identified and fenced to exclude rabbits and other stock. The area was originally referred to as the Arid Region Flora Reserve but later was named the TGB Osborn Vegetation Reserve after its founder. For simplicity it is commonly referred to as the Koonamore Vegetation Reserve. <br></br> <p>This record is a collection of flora and fauna observations conducted in the TGB Osborn Vegetation Reserve (or Koonamore Vegetation Reserve). </p> <br></br>These records are organised accordingly :<ul style="list-style-type: disc;"> <li><a href="https://portal.tern.org.au/metadata/TERN/90a26f3a-cf42-41e5-ada4-9b0166b15b09">Vegetation Quadrats</a></li> <li> <a href="https://portal.tern.org.au/metadata/TERN/05f37d50-935e-4a0a-b45e-cb1b606ce476">Photopoints</a></li> <li> <a href="https://portal.tern.org.au/metadata/TERN/c593e881-ddb4-408a-ba5d-6a5f9d258b39"><em>Cassia</em> Corner</a></li> <li><a href="https://portal.tern.org.au/metadata/TERN/aff278df-c8e8-41ab-b22e-66ea7d466169"><em>Myoporum platycarpum</em> plant individuals</a> </li> <li><a href="https://portal.tern.org.au/metadata/TERN/615b121a-3c4f-41b5-90f6-1b7e95ce7a9d">Saltbush Transects</a></li> <li><a href="https://portal.tern.org.au/metadata/TERN/d3e676a3-bf84-439f-ae99-0ce631ec6d64">Senna Populations</a></li> <li><a href="https://portal.tern.org.au/metadata/TERN/dfe1b721-19c1-4f88-91c3-23f438c6f531">Kangaroo Transects</a></li> <li><a href="https://portal.tern.org.au/metadata/TERN/e6448738-d870-432d-9795-955c90f6ee6e">Rabbit Warren Monitoring</a> </li>

<p>The Biological Databases of South Australia (BDBSA) is South Australia's flora and fauna database that stores and manages specimen and observation records. This metadata record is the <i>Flora Survey</i> component that contains 1,050,631 plant measurements collected from 224,572 sites, across 5565 plant species since 1976. The dataset contains important vegetation structural attributes, with parameters such as crown openness, crown depth and crown separation ratio, including observations on plant occurrence data and fire disturbance related parameters. The resulting database provides a comprehensive record of biodiversity across sites visited during a diverse range of biodiversity projects undertaken in South Australia and provides a basis for future monitoring or other relevant work such as species modelling.</p> <p>Only validated BDBSA data is made publicly available and all records of sensitive taxa have been masked from the dataset. Data is accessible from the <a href="https://ecoplots-test.tern.org.au/search?dataset=bdbsa&search_logic=or#/">TERN EcoPlots</a>, which provides the ability to extract subsets of flora data across multiple data collections and bioregions.</p>
