WEED specialists will treat an infestation of sea spinach (Tetragonia decumbens) on the Seabird seawall this month.

Shire of Gingin president David Roe said the treatment was part of the current rehabilitation process, and the local community would plant native species in July and August.

“Sea spinach is an invasive weed that is prevalent in coastal areas throughout the region and strong growth over past six months on the seawall suggests that if left untreated the sea spinach will out-compete native plants,” Councillor Roe said.

“Treatment of the sea spinach will help to reduce competition for the existing native plants which were planted by the community in 2016 and assist new native seedlings for planting in 2017.

“This will be a one-off treatment however the site may require several treatments over the next 12-24 months to allow the local native seedlings to fully establish.”

The Northern Agricultural Catchments Council recently released a mobile phone app to help people identify native species and weeds.

The free Coastal Plant Pocket Guide, available on iTunes and Google Play, provides information about species identification, distribution, propagation and uses by Aboriginal people.

It also includes commonly encountered weed species, and how to control them.

“This is a great resource for community groups, schools, local government authorities and contractors to help identify and understand these common species on our coast,” coastal and marine project co-ordinator Mic Payne said.
