Hi guys,
Walking along the old tramway track to Winterbrook falls recently (note that the road across bridge is still washed out), we noticed an abundance of these poly tubes with funnels on the top. There must be at least tow dozen of them scattered near the old flumes in the rainforest area.
Curious as to whether anybody knows what they are, they have 'Univeristy of Melbourne' written on the side of them - my guess is to catch king billy fronds for research?
