Long Term Ecological Research Network

  1. 1. Presentation by Emma Burns, Executive Director
  2. 2. Integrated purpose LTERN’s objective: To integrate key established plot networks across Australia to tackle critical questions associated with the impacts of disturbance on Australian ecosystems Australian Government Investment Goal: A sustainable set of long term data collection procedures and archives from plots across Australian ecosystems measuring selected flora, fauna and biophysical processes, suitable for key ecosystem science questions and for developing and testing ecosystem models
  3. 3. A research enabler Infrastructure to allow the research community to: – Develop a detailed understanding of the behaviour and regulation of key ecosystem functions and processes, including influence of interacting abiotic and biotic factors on landscape function. – Quantify critical relationships between vegetation condition and/or biodiversity and major disturbance regimes such as those associated with fire, logging, livestock grazing, invasive species and climate change. 3
  4. 4. Spatial distribution of the plot networks • 12 Plot Networks • 1,119 sites • 9 Principle Investigators/Network Leaders • 8 Institutions

  17. 17. LTERN Publications Fit-for-purpose, consistent, long-term monitoring is crucial to measure and understand key attributes of ecosystems— and the human and natural process that affect them. This need, its challenges, and their potential solutions have been written about by members of LTERN in a range of publications. Publications

Publications Catalogue 0 50 100 150 200 250 300 NumberofPublications LTERN Publications per Plot Network as of September 2015 • 1,049 publications generated to date • Since September 2014, 143 new publications To provide a central and comprehensive list of all relevant LTERN publications; and to demonstrate the research productivity of this infrastructure through one type of metric (i.e. written outputs).

  20. 20. The value of time-series data Reference: Dickman, C. R., et al. (2014). Desert Complex Environments. In Biodiversity and Environmental Change: Monitoring, Challenges and Direction. E. B. David Lindenmayer, Nicole Thurgate, Andrew Lowe., CSIRO Publishing: 379–438. The data and stories from the book, and the subset available through the data portal, demonstrate the value of time-series data and the potential misinterpretations that could result from short-term monitoring

The legacy of past logging practices, as well as current clearfelling, is driving the system towards collapse. Modelling suggests that even if logging ceased today, and there were no bushfires, there is still a 92% chance of ecosystem collapse Up listing of the threat status of leadbeater’s possum from endangered to critically endangered

  23. 23. Where to from here? Primary Priority: Continued repeated data collection from across LTERN. Secondary Priority: Continued publication of data collected and then, as feasible, publication of the background data. Based on current funding levels it is estimated that it will take at least 5 years to curate and publish all our data. Secondary Priority: A new challenge…..What can the data from within plot networks tell us collectively? Can multiple datasets collected from different studies for different purposes be used collectively to test a relevant and important continental scale science question? Proof of concept project: under a unifying lens of long-term climate data and climate projections—examine variation and patterns in long-term datasets, and model/predict future and past variations and patterns. And of course increased integration with international observatory networks and initiatives.
