Presentation Description

Australia’s Murray-Darling Basin (MDB) has experienced significant flooding over 2022-23, and its effect on vegetation condition is unknown. Floodplain inundation stimulates vegetation growth by replenishing soil moisture to provide water resources to develop and support new canopy, however it is uncertain how long such benefits may last, especially across large spatial scales. The aim of this study was therefore to assess post-flood vegetation responses as a result of two key flood periods – 2016 and 2022. Multiple sources of remote sensing data was coupled with field measured evapotranspiration to identify inundation areas and assess tree condition. New knowledge gained from this analysis will help to understand tree responses to inundation and duration of benefit via increased canopy productivity. The intent is to aid catchment and regional water management, particularly in maintaining healthy ecosystems.

Acknowledgement of Country

The Flow-MER Program team acknowledges the First Nations communities of the Murray–Darling Basin and pays respect to Elders past and present.

We acknowledge First Nations people as the Traditional Owners of the land, water and sky Country across the Basin and value the expertise, wisdom and enduring connections that have informed their care for Country over millennia.

We recognise the intrinsic connection of First Nations people to Country, and we value the enduring cultural, social, environmental, spiritual, and economic connection to the rivers, wetlands, and floodplains of the Basin. We are committed to working with First Nations people across the Murray–Darling Basin to build relationships in a meaningful and genuine way to support and empower them in reaching their aspirations.
