Bridal Creeper poses one of the biggest threats to our precious local species across most of Southern Western Australia and is recognised as a weed of national significance. A strip of land in the original area along the Hopetoun foreshore still has a large infestation, due to very soft humus soil that is very conducive to Bridal Creeper growth. Our Licensed Pest Management Technician treated the area in August 2021 and will again be sprayed in early spring just before flowering for maximum effect.
Bridal creeper is a perennial climbing vine, which can sprawl for several metres, smothering the plants around it. It’s a “Declared Pest” in WA and is nationally recognised as a ‘Weed of National Significance’. This highly invasive weed causes serious problems outcompeting native plants and crops by smothering or preventing germination.
To begin addressing this significant issue within the Shire, the Southern Biosecurity Group funded a project that facilitated 4.6 hectares of bridal creeper control along the Hopetoun foreshore. The area treated was identified as a high priority due to its visual exposure, public access, and proximity to the RV camping area as well as other patches of remnant coastal vegetation and mallee communities.
The work was carried out by a team of two Licensed Weed Management Technicians using a light hand spray method over three days in October. Taking environmental considerations into account and to ensure that the surrounding native vegetation was minimally affected, the application was selectively hand sprayed at a very low dosage. A red dye was also incorporated into the solution to make the treated area easily visible. Signage was also used as a precaution to warn people to stay out of the treated area. The naturally occurring biological control agent known as ‘rust fungus’, or Puccinia myrsiphylli, was also released in the targeted area in an attempt to initiate its spread throughout the district.
