Peter spotted this opportunity to listen on to what looks like an interesting webinar.

Saturday 21 May is World Fish Migration Day, which aims to create awareness about the importance of migratory fish and free-flowing rivers.

Within Australia’s great Murray-Darling Basin, native fish populations are currently estimated to be about 10% of pre-European settlement. One such species is the endangered Macquarie perch (Macquaria australasica).

Join Bush Heritage Australia’s Lis McClellan as we showcase the work of an exciting project using Light Detection and Ranging (LIDAR) remote sensing and drone surveys to assess natural barriers to assist with environmental flow planning for Macquarie perch spawning migrations in the upper Murrumbidgee River.

All the information and registration link is available here.
