SWIFFT Seminar notes 28 July 2022

Arthur Rylah Institute – Science that matters 

SWIFFT Seminar 28 July 2022

 

SWIFFT  seminar notes are a summary of the  seminar and not intended to be a definitive record of presentations made and issues discussed.

This SWIFFT seminar was conducted online with 242 participants via Microsoft Teams.  SWIFFT wishes to acknowledge support from the Department of Environment, Land, Water and Planning, Victoria in organising the seminar and thank the speakers from ARI for their time and delivery of presentations. Also, thanks to Michelle Butler who chaired the session from Ballarat and acknowledged Traditional owners, Elder’s past and present on the lands covered by the meeting.

 

Key points summary

 

ARI intro

Introduction to Arthur Rylah Institute for Environmental Research (ARI)
  • ARI is part of the Department of Environment, Land, Water and Planning.
  • ARI helps contribute information to the people of Victoria on how to manage our natural environment.
  • ARI science underpins high quality evidence-based decision making by governments and communities.
  • ARI scientists work across plants, animals, natural systems, rivers, coasts, grasslands, alps, and forests but importantly much of the work involves co-operation and involvement of the community.

  • The ARI web site has information on research projects, e-news and seminars.

 

Zeb Tonkin intro

Monitoring ecological outcomes of water for the environment across Victoria
  • River regulation has disrupted the natural flow of waterways resulting in major impacts to ecosystems and native flora & fauna species.
  • Water for the Environment (environmental flows) is aimed at restoring aspects of natural flow regimes flow altered systems.
  • The effective use of environmental water is reliant on having a good understanding of species ecology, populations and flow requirements.
  • Research is conducted through the Victorian Environmental Flow Monitoring Assessment Program and the Victorian Wetland Monitoring Assessment Program.

 

Regan intro

Using decision science to address complex environmental problems
  • ARI is applying Decision Science to provide evidence-based decision making and transparency in the decisions being made.
  • There has been a shift over time from managing one or more species to encompassing whole ecological systems along with other competing values.
  • Placing community at the centre, valuing nature and recognising traditional owner values are key aspects of the decision-making process.
  • Structured Decision Making focuses on making optimal choices based on the available information.

Peter Griffioen  intro

Identifying species from their calls with A.I. Deep Learning meets birds, bats and frogs
  • Automatic sound recorders are being used to identify endangered species, communities of fauna and feral animals.
  • ARI is developing ways of improving the accuracy and efficiency of processing large amounts of acoustic data from the field focusing on frogs, birds and bats.
  • The model being used is a 1-D Convolutional Deep Neural Network using TensorFlow (some similarity to the technology used in Shazam music app).
  • Sound recordings provide scientists with the information to discover species in an area and look at changes over time or in response to events such as bushfires.

Durkin intro

In search of Watson’s Tree Frog in a post-fire landscape – using genetics to inform conservation management
  • Watson’s Tree Frog was only described in 2020 as a distinct species of the Large Brown Tree Frog and is considered endangered Nationally and critically endangered in Victoria.
  • In Victoria, there were no records between 1996 and 2015 (19 years). It is now known to exist at 43 sites within the East Gippsland forests and is being monitored using passive acoustic recorders.
  • The January 2019/20 Black Summer bushfires burnt 85% of Watson’s Tree Frog known habitat with the species being detected at 64% of sites post fire but long-term impacts need to be monitored.
  • Watson’s Tree Frog has low genetic diversity in Victorian populations which may require genetic rescue from NSW populations into the future after confirming the taxonomic status.

Kate Lee intro

How do we make connecting and acting for nature the norm?
  • ARI is involved with a large number of stakeholder organisations and groups in collaborative research aimed at helping people connect with and act for nature.
  • The Victorian’s Valuing Nature program is part of a 20-year plan, Biodiversity 2037, which  recognises the importance of community in protecting nature.
  • The annual Victorian Nature Festival is one of the flagship events in helping people connect with nature comprising social media and virtual on-line events.
  • Victoria is developing a state-wide Biodiversity Citizen Science strategy which includes evaluation of citizen science.
  • Work is underway to develop a nationwide program to encouraging people to be responsible pet owners, particularly in relation to containing pet cats and protecting wildlife.
