Webinar Topic: Understanding trends of woody vegetation using field evapotranspiration and remote sensing

New broadscale information to identify and understand trends in vegetation response to water are required to plan where, when, and how long, to target environmental water to specific locations in order to maintain ecosystem function.

In this project we are using field collected water use data (evapotranspiration) for River red gum and Black box to calibrate the outputs of a Basin-scale remote sensing evapotranspiration model. Evapotranspiration is a surrogate for vegetation condition, and outputs of this model allow us to observe trends in vegetation condition from 2001 to current time, for each remote sensing pixel in the Murray-Darling Basin. Data can be observed at various intervals depending on the management questions, and include weekly, monthly, seasonally, annually (for example). Some questions we are exploring include:

  • What do existing remotely sensed models tell us about the antecedent and current condition of long-lived woody floodplain vegetation at regional and Basin-scales?
  • How are vegetation condition and trends related to hydrology across scales including Basin-scale?
  • Determine condition of long-lived woody floodplain vegetation prior to the involvement of CEWH water;
  • Understand the influence of environmental water on woody vegetation condition

Join us for the final webinar in this Winter/Spring Flow-MER Friday Series.

About Tanya

Dr Tanya Doody is a CSIRO Principal Research Scientist specialising in ecohydrology with a focus on field measurement of tree water use to understand vegetation water requirements and the links between water availability and vegetation condition. Tanya leads the Flow MER vegetation Theme as well as a research project that will enable scaling of floodplain tree water use and hence condition, across the Murray-Darling Basin using remote sensing.

The Flow-MER program team acknowledge and respect the Traditional Owners as the First Peoples of the lands and waters of the Murray Darling Basin. We recognise their unique ability to care for Country and their deep spiritual connection to it. We honour Elders past and present whose knowledge and wisdom has ensured the continuation of culture and traditional practices. We are committed to genuinely partner, and meaningfully engage, with Traditional Owners and Aboriginal communities to support the protection of Country, the maintenance of spiritual and cultural practices and their broader aspirations in the 21st century and beyond. In particular we acknowledge the Traditional Owners of the seven Selected Areas where Flow-MER research is focussed.
