Arum Lily Blitz
The army in the war against the South West's worst invasive w**d has grown this year.
Managed by Nature Conservation Margaret River Region, the Arum Lily Blitz team say they've had another record-breaking year to stop the spread of the w**d.
Despite their beautiful appearance, arum lilies are toxic to native plants and found widespread throughout the region.
Arum Lily Blitz officer Ben Howell told Stan Shaw on ABC South West Breakfast they've experienced highest participation numbers so far.
"We're up to 2200 properties registered since the start of the program in 2019," he says.
"Over 30,000 hectares currently under management, eight businesses supporting us with herbicide distribution... and also record year for people picking up that herbicide which sort of indicating that lots more people are getting on board."
Mr Howell believes there's still a long way to go in educating the public about the deceivingly attractive w**d.
"A lot of people do think they are beautiful... but once you see what they are doing to the biodiversity of the region and smothering areas of native vegetation you kind of get that picture of it being fairly ugly."
New collaborative strategies included involving school kids with infestation mapping and cave divers removing the w**ds from the South West's famous caves, an initiative through the Capes Foundation.
"This year they had some local cavers from the Leeuwin caver club, and they were able to abseil into the doline of the Lake Cave and we were able to target the arum lilies growing in there - they're not selective, they'll grow everywhere."
