    Data were used to demonstrate fitness impacts caused by fragmentation context. Showed extensive pollination can protect tree fitness from fragmentation. Grew open-pollinated progeny arrays of the bird-pollinated, mallee tree <i>Eucalyptus incrassata</i> in a randomised block design in a common garden experiment at Monarto, South Australia. Progeny arrays were collected from parental trees in either continuous forest or highly fragmented contexts. Data are therefore experimental, for hypothesis testing Data are not descriptive ecological, not plot based and not time-series. Data are not a representative sample of <i>Eucalyptus incrassata</i> and not representative of mallee eucalypts.

    <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>

    This dataset presents the demographic monitoring (growth and survival) of 81 tree species based on repeated stem measurement data from 20, 0.5 ha (100 m x 50 m) permanent moist forest plots in northern Queensland, Australia from 1971 to 2019, as well as four additional plots of 0.1 to 1 ha whose monitoring began in the 2000s. The plots have a rainfall range of 1200 to over 6000 mm, represent eleven vegetation types, six parent materials, and range from 15 m to 1500 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. We only report the data for the 81 species studied in Bauman et al. 2022 (Nature), here. We also provide the climatology of these plots as well as the temperature, vapour pressure deficit, and maximum climatological water deficit of all intervals separating consecutive censuses, as used in the analyses of Bauman et al. 2022.

    <p>This record is a collection of photopoints from surveys conducted in the TGB Osborn Vegetation Reserve (or Koonamore Vegetation Reserve (KVR)) since the early 1900s. Photographs have been taken approximately annually from 1926 until 2024 at a series of set positions (photopoints) by staff and students of the University of Adelaide. The duration of the record available digitally extends from 1907 (observations) to 2008 (photographs). These include stand-alone positions, corners of quadrats and points along transects. Photographs may have been taken in more than one direction at each point, and/or in black and white or colour. Each photograph was annotated according to what could be seen on the photograph, individual species identified, numbers given to each plant (not always reliable from event to event). Occasionally information on canopy diameter measured along EW and NS direction, plant height and plant mortality status is presented.</p> This is version 2.0 of the Koonamore photopoint data release and supersedes any previous versions.

    <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>
