The composition of many eastern Australian woodland and forest bird assemblages is controlled by a single, hyper-aggresive native bird, the noisy miner <em>Manorina melanocephala</em>. The "Avifaunal disarry from a single despotic species" working group harnessed diverse existing datasets and used them to develop and test models of noisy miner occupancy and impacts. Two datasets are published based on the analysis and synthesis.

The dataset catalogue information about research or management projects that have used remote devices to record behavioural, physiological or environmental data from free-ranging animals. The purpose of this dataset is to act as a conduit by which animal telemetry data, ideas, analysis and statistical tools may be shared between interested parties throughout Australasia. The animal telemetry projects collated in this dataset have been collated from peer-reviewed scientific papers published between 2000 and 2013. This represents the first-step in the creation of an Australasian focused database for animal telemetry research and management projects. If you have undertaken a telemetry project and it is not listed here, whether the study findings have been published or not, then please send details about the study to the dataset contact person. If applicable, the details will be incorporated. These data were compiled as part of the ACEAS working group project titled "Advancing the application of animal telemetry data in ecosystem management".

We conducted a four-step Delphi expert elicitation procedure. This approach allowed us to address the gaps in knowledge regarding national koala populations with the robustness of collective judgement. The four steps of the Delphi method ask for an upper estimate, a lower estimate, a best guess and a percentage confidence interval. Prior to the commencement of the workshop, the participants were required to complete the first round of the questionnaire. These results were then re-evaluated during the workshop and a second round of elicitation was conducted. The outcome of the two workshops will be a synthesis of the distribution and abundance of koalas, population trends, and a region-specific summary of threats to koalas. Peer-reviewed journal publications will be produced. The information will be used to inform researchers, managers and decision-makers to ensure that viable koala populations persist across their natural range.

<p>The record comprises data on rabbit warren surveys conducted within the TGB Osborn (Koonamore) Vegetation Reserve (KVR) from 1977 to 2014 as part of ongoing rabbit control efforts. The Reserve was divided into 400x400 m grid squares (with exceptions for row 5 and column 6), and warrens were identified based on the presence of at least four rabbit holes. In some years, the entire Reserve was surveyed; in others, only a subset was covered. All identified warrens or holes were fumigated and filled following detection.</p> <p>This is version 2.0 of the Koonamore Rabbit Warren Survey data release.</p>

This dataset consists of counts for multiple plant species obtained from the Ethabuka Station and Carlo Reserve in the Simpson Desert, Australia, from 2004-2013 by the Desert Ecology Research Group (DERG) in conjunction with LTERN. It also consists rainfall data obtained from 2004-2012. These datasets were used to perform a Dynamic Factor Analyses for the manuscript, "Life form explains consistent temporal trends across species: the application of dynamic factor analysis". For more information see: DERG; https://www.sydney.edu.au/science/our-research/research-areas/life-and-environmental-sciences/desert-ecology.html.

This dataset consists of counts of plants and seeds for the ephemeral desert herb <i>Trachymene glaucifolia</i> obtained from the Ethabuka and Carlo Reserves in the Simpson Desert, Australia, from 2004-2011 by the Desert Ecology Research Group (DERG) in conjunction with LTERN. It also consists of monthly rainfall data obtained from 1995-2012. Collectively, the dataset was used to construct Multivariate Auto-regressive State-Space (MARSS) models for the manuscript "Reducing common sources of uncertainty in time series population data using MARSS models".

<p>In 1997, many very young <em>Senna</em> seedlings were noticed in the Cassia corner and outside the northern boundary fence. To study the effects of grazing on these seedlings outside the reserve, three populations were identified and measured to the north of the fence, and a fourth population just south of the fence in the Reserve, not otherwise enclosed. </p> <p>Two of the outside populations were enclosed in triangular fences, one with sheep netting to protect from grazing by sheep, the other with both sheep and rabbit netting to protect against both sheep and rabbits. A third population was left unprotected. The population inside the Reserve was assumed to be protected from all grazing by the Reserve fence. The aim was to follow the fates of the original cohort. </p> <p>This is version 2.0 of the Koonamore Senna Population data release.</p>

Seedling surveys were conducted at the Cumberland Plain site in 2014. The identity and height of all seedlings were recorded along six 20 m x 1 m transects in the core 1 ha plot.

<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 describes the occurrence of bird species at sites within a burnt woodland. These sites comprise the following design: 5 replicate block. each with 2 large patch sites, 2 small patch sites and 2 matrix sites. One site of each pair was relatively more isolated than the other (surrounded by a higher proportion of unburnt vegetation). In addition, there are also 6 sites located beyond the extent of the fire. The data-set also lists vegetation attributes at each of these sites.
