Over the past two days Department of Biodiversity, Conservation and Attractions (DBCA) has contracted a monster of a machine to dig out some of the fast encroaching Bulrush, Typha orientalis, around the Olive Seymour Boardwalk, to protect the natural habitat and open up the view on the northern side.
It is able to rip the Bulrush clean out, rhizome and all, so it will be a while before the plant surrounds the walkway. Previously, a team of workers had to wade in the water and do the job by hand.
Typha orientalis is not native to Western Australia and is an aggressive weed that can suppress other vegetation and become dominant, and has also been linked to excessive water nutrients.
Thanks to DBCA for undertaking the groundworks.
