It’s not a botanical term. It is an ecological term used to describe the
broken remains of Allocasuarina seed cones lying under the tree after being
broken by birds (usually Glossy Black-Cockatoos) in the process of extracting
the seeds. The number of orts under a tree is used as a measure of the level
of food/feeding activity at the tree and the colour of the orts provides a
guide to the length of time that has elapsed since they were broken.
